Terms of Use

You accept these Terms when you click "Create free account", when you use the Free Demo, or when you otherwise access the Service. Our Privacy Policy and Cookie Policy explain how we handle information and form part of these Terms. If you do not agree, do not use the Service.

The Service is for business use. You must be at least 18 years old and able to enter into a binding contract. If you use the Service for a company or other organization, you confirm that you have authority to bind it, and "you" means that organization. Sole proprietors and individuals acting for a business are business users.

Section 17 contains an arbitration agreement and class-action waiver that affect how disputes are resolved. You can opt out within 30 days as described there.

"Account"

The registered account you create to use the Service through customer.dqverify.com.

"API"

The DQVerify application programming interface, endpoints, SDKs and developer tools described in the Documentation.

"API Key"

The secret credential issued to your Account that authenticates API calls.

"Credits"

The unit of consumption for the Service. Each validation module (address, email, phone) consumes one Credit per call; a call that uses all three modules consumes three Credits. "Free Credits" are granted at sign-up; "Purchased Credits" are bought in credit packs.

"Customer Data"

Addresses, email addresses, phone numbers and related records that you submit to the Service for validation, through the API, the platform or a batch upload. Also called Validation Data.

"Documentation"

The API documentation, help center and pricing information published on dqverify.com, as updated from time to time.

"Free Demo"

The validation widget on dqverify.com that anyone can use without an Account.

"Output"

The results the Service returns for Customer Data, including standardised addresses, validation statuses, codes and appended fields.

"Service"

The DQVerify website, platform, API, batch tools, Free Demo and related services provided by DQE.

"USPS Data"

Address data, products and marks of the United States Postal Service used in address validation, including DPV, CASS, ZIP+4 and RDI.

Accurate information. Give us accurate, current registration details and keep them updated. You must register with a business email address.

Credentials are secrets. You are responsible for keeping your account password and API Keys confidential and for all activity under your Account, whether or not you authorized it. Do not share API Keys or commit them to public repositories. Tell us at once at legal@dqverify.com if you believe a password or API Key has been compromised; we may rotate or revoke keys to protect the Service.

Google and Microsoft sign-in. If you sign in with Google or Microsoft, you are responsible for that provider account, and we may rely on the provider's confirmation that you control the email address it reports.

One organization, one trial. Each organization may hold one Account with Free Credits. Creating multiple Accounts to obtain more Free Credits is a breach of these Terms.

Free Demo. The Free Demo on dqverify.com is provided for evaluation only. It is rate-limited (currently 3 requests per module per 30-minute window per IP address), carries no service-level commitment, and may be changed or withdrawn at any time. You must not script, automate or otherwise circumvent the Free Demo, use it in a simulated manual-entry mode, or use it to generate or compile lists. The Free Demo is provided "as is" and Sections 13 and 15 apply to it.

Free Trial. When you create an Account with a business email address, we grant Free Credits so you can test the Service before buying. No credit card is required. Free trial credits (currently 100) are valid for 14 days from account creation; unused trial credits expire at the end of the trial or when you buy a credit pack, whichever comes first. Free Credits have no cash value and cannot be transferred, sold or exchanged. We may change or end the Free Trial for new sign-ups at any time. Sections 6 and 8 apply to Free Credits and the Free Demo in full.

Plans. We currently offer three plans: Validate (the free tier described in Section 4), Verify (one-time credit packs) and Enterprise (custom volumes, connectors and terms set out in a signed order form or agreement, which prevails over these Terms if they conflict). Prices, pack sizes and what each plan includes are those shown on the pricing page at the time of purchase.

How Credits are consumed. Each validation module consumes one Credit per call; a call using address, email and phone consumes three Credits. Credits are consumed whether or not the input is valid.

One-time purchases, no renewal. Purchased Credits are sold as one-time packs. There is no subscription, no monthly fee and no automatic renewal; nothing is charged again unless you buy another pack. Purchased Credits are valid for 12 months from the date of purchase; unused Credits expire at the end of that period.

Payment. Payments are processed by Stripe on Stripe-hosted pages. We do not store full card numbers. All fees are in US dollars and exclude sales, use and similar taxes, which you are responsible for unless you give us a valid exemption certificate. Enterprise customers pay under the terms stated in their order form or agreement.

Refunds. Credits that have been consumed are non-refundable. Unused Purchased Credits are not refundable except as required by law or as DQE agrees in writing. If we discontinue the Service or a module before your Purchased Credits expire, we will refund the unused portion.

Price changes. We may change prices for future purchases at any time by updating the pricing page. Price changes do not affect Credits you have already bought.

Rate limits. The API is subject to the rate limits we communicate for your plan or publish in the Documentation. Requests over the limit may be throttled or rejected. Throttling is not a service failure and does not entitle you to a refund.

You may use the Service only for your own internal business purposes: to validate, correct and standardise addresses, email addresses and phone numbers that you already lawfully hold, and to use the Output in your own applications and records. You must not, and must not allow anyone else to:

• Resell or redistribute. Sell, rent, lease, sublicense, publish or otherwise make the Service or Output available to third parties as a standalone product, or use the Service to build a competing validation or data-enrichment product.
• Compile lists. Use the Service or Output to create, compile, augment or verify mailing lists, address databases or contact lists that you do not already lawfully hold, including by iterating through address ranges, harvesting autocomplete suggestions, or generating phone numbers or email addresses artificially. See Section 8.
• Automate the Free Demo. Script, scrape, or bypass the rate limits of the Free Demo or the Service.
• Submit unlawful data. Submit Customer Data that you do not have the right to submit, that relates to a person you know to be under 18, or that you know to be inaccurate or fraudulent.
• Make eligibility decisions. Use the Service or Output as a factor in deciding a person's eligibility for credit, insurance, employment, housing or any other purpose covered by the Fair Credit Reporting Act. DQVerify is not a consumer reporting agency and the Output is not a consumer report.
• Reverse engineer. Reverse engineer, decompile or attempt to extract the source code, algorithms or underlying USPS or third-party datasets of the Service.
• Interfere. Probe, scan or test the vulnerability of the Service without written permission; introduce malicious code; or interfere with the integrity or performance of the Service.
• Break the law. Use the Service for harassment, stalking, discrimination, fraud, or any activity that violates applicable law, including the laws in Section 7.

We may suspend or terminate access for breaches of this Section under Section 16.

Validation tells you whether an address, email address or phone number appears valid. It is not consent from the owner to be contacted, and it does not tell you whether you may lawfully contact that person.

You are solely responsible for complying with the Telephone Consumer Protection Act (47 U.S.C. 227), the FCC's rules at 47 CFR 64.1200, the National Do Not Call Registry rules, the Telemarketing Sales Rule, the CAN-SPAM Act (15 U.S.C. 7701 and following) and all state telemarketing, text-messaging and email laws, as in effect from time to time, in any calls, texts or emails you send to contacts validated through the Service. This includes obtaining any consent the law requires, honoring opt-outs and revocations, scrubbing against do-not-call lists and respecting calling hours.

Line-type results (mobile, landline, VoIP) are informational and are not a sole basis for deciding how a number may be contacted. You will indemnify us under Section 14 for claims arising from your calls, texts, emails or other outreach.

Address validation is performed with USPS CASS Certified software and USPS-licensed data supplied to DQE by a USPS licensee. DQE is not itself a USPS licensee. The USPS license terms below apply to you.

• Legitimately obtained addresses only. You may use the address service only to process addresses you already lawfully hold. You must not use it to create address lists artificially.
• No list compilation and no derivative products. You must not use the Service or Output to artificially compile or maintain a list of addresses not already in your possession, or to create derivative products from USPS Data.
• No renting or selling processed lists. No address list that contains addresses or address attributes updated through the Service may be rented, sold, distributed or otherwise provided, in whole or in part, to any third party.
• Online lookups. Single-address lookups (including the Free Demo) confirm whether an input matches a known address record. You must not automate submissions to the online lookup in a simulated manual-entry mode.
• Stop processing. USPS seeds its data with artificial addresses to detect misuse. If one is detected, validation of the affected list stops immediately and a one-time restart code is required. You must notify us at once at legal@dqverify.com when this happens. We (or our USPS licensee) are required to report your company name and address and the affected addresses to USPS, and those reports are kept for five years. We may suspend the affected list or your Account while the matter is resolved, and must suspend your processing if USPS requires it after repeated incidents. USPS text: "During the processing of your list, an artificially created address was detected. In accordance with the License Agreement between USPS and the licensee, this USPS product shall be used to process legitimately obtained addresses only, and shall not be used for the purpose of artificially creating address lists. Continuing use of this product requires compliance with all terms of the License Agreement. If the customer believes this address was identified in error, contact the Licensee."
• No raw data. You receive per-request Output only. You get no rights in the underlying USPS reference files, and you must not attempt to reconstruct them.
• Notices and safeguards. Keep any USPS or DQVerify attribution in Output and apply reasonable safeguards to USPS-derived data.
• USPS ownership and non-endorsement. USPS owns all rights in USPS Data and its marks. DPV, CASS, ZIP+4, ZIP Code and USPS are trademarks of the United States Postal Service. USPS does not endorse DQVerify.
• Data currency. USPS Data is updated on USPS release cycles. Output reflects USPS deliverability status at the time of the request and is not a guarantee of delivery or occupancy.
• Changes. If USPS changes its license terms or certification requirements, we may change these terms or the address service on notice. If that materially reduces the Service, Section 5 (Refunds) applies to unused Purchased Credits.

Ownership and license. You own Customer Data and, as between you and us, the Output. You grant us a non-exclusive license to process Customer Data to provide the Service, to prevent abuse (including USPS misuse detection), and as required by law.

Your responsibilities. You are solely responsible for the accuracy, legality and lawful collection of Customer Data, including any notices or consents required to submit it to us, and for the results of your use of the Output.

Our role. We act as your service provider for Customer Data. We do not sell it, use it for our own marketing, combine it with other data to enrich or target, or use it to build lists.

Retention. We do not retain the addresses, email addresses or phone numbers you submit once your request is complete. Batch results are available for download during your session and are then deleted. If you do not download them, they are still deleted. Download your results before you leave the page. Inputs typed into the Free Demo are processed in real time and are not stored by the website.

Service providers and location. The service providers that may process Customer Data, and where the Service is hosted, are listed in the Privacy Policy (Sections 5 and 10). You acknowledge that validation processing is performed by our affiliate in the European Union and by our licensed US data partner, as described in the Privacy Policy. We may add or replace service providers and will update that list.

Security and breach notice. We use reasonable administrative, technical and physical safeguards designed to protect Customer Data, as described in the Privacy Policy. If we confirm a breach of security affecting your Customer Data, we will notify you without undue delay and within the time required by applicable law.

Deletion. Because Customer Data is not retained after processing, nothing further is needed on termination. Account data is handled as described in the Privacy Policy, Section 12.

We offer connectors and listings for third-party platforms such as Salesforce, Shopify, Adobe Commerce, AWS, Snowflake and Microsoft Azure. Those platforms are provided by their owners under their own terms and privacy policies, which govern your use of them. We do not control them and are not responsible for their availability, security or handling of your data. If you connect a third-party platform to the Service, you authorize us to exchange Customer Data and Output with it as needed to make the integration work.

Our rights. DQE and its licensors (including USPS and our affiliate DQE Software SAS) own the Service, including software, algorithms, APIs, Documentation, trademarks and underlying datasets. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the Service for your internal business purposes during the term. All rights not expressly granted are reserved.

Feedback. If you send us suggestions or feedback, you grant us a perpetual, irrevocable, royalty-free license to use it without obligation to you. We will not identify you as the source without your permission.

Each party will keep the other party's confidential information confidential, use it only to perform under these Terms, and protect it with at least reasonable care. Your Customer Data is your confidential information. Our non-public pricing, Documentation marked confidential, and security information are ours. Confidential information does not include information that is public through no fault of the recipient, already known to the recipient, independently developed, or lawfully received from a third party. A party may disclose confidential information when required by law after giving reasonable notice where permitted.

Accuracy of results. Results depend on USPS Data and third-party data sources that change over time and may contain errors or gaps. We do not guarantee that an address is deliverable or occupied, that an email inbox exists or accepts mail, or that a phone number is in service or of a particular line type. Results are indicators, not guarantees. You must not rely on the Output as the sole basis for decisions that have legal or similarly significant effects on a person.

We do not warrant that the Service will be uninterrupted, error-free or secure, or that defects will be corrected. Any service-level commitment is set out in your Enterprise agreement.

By you. You will defend, indemnify and hold harmless DQE, its affiliates and their officers, employees and agents from any third-party claim, and the resulting damages, penalties, costs and reasonable attorneys' fees, arising from: (a) Customer Data or your collection of it; (b) your calls, texts, emails or other outreach to contacts validated through the Service, including claims under the TCPA, CAN-SPAM or state law; (c) your breach of Section 6, 7 or 8; or (d) your violation of law or of a third party's rights.

By DQE. We will defend you against a third-party claim that the Service, used as permitted by these Terms, infringes a United States patent, copyright or trademark, and pay the damages finally awarded or agreed in settlement. This does not apply to claims arising from Customer Data, your modifications, combinations with products we did not supply, or use after we told you to stop. If a claim is made, we may modify the Service, obtain a license, or terminate the affected part and refund unused Purchased Credits. This Section states our entire liability for infringement.

Procedure. The indemnified party must give prompt notice of the claim, allow the indemnifying party to control the defense and settlement (no settlement may impose obligations on the indemnified party without its consent), and give reasonable cooperation.

Cap. DQE's total liability arising out of or related to these Terms or the Service will not exceed the greater of (a) the fees you paid to DQE in the 12 months before the event giving rise to the claim, or (b) USD 100.

Excluded claims. The exclusions and cap above do not apply to your payment obligations, either party's indemnification obligations, your breach of Section 7 or 8, or a party's gross negligence, fraud or wilful misconduct, and do not limit liability that cannot be limited by law.

Some states do not allow certain exclusions or limitations; in those states our liability is limited to the fullest extent the law allows.

Term. These Terms apply from the moment you first use the Service and continue until your Account is closed. You may close your Account at any time in the customer portal where that option is available, or by emailing support@dqverify.com.

Suspension. We may suspend all or part of the Service, with notice where practical, if: (a) you breach Section 6, 7 or 8; (b) USPS misuse detection is triggered or USPS requires suspension; (c) your use threatens the security or integrity of the Service; (d) you fail to pay amounts due; or (e) continued service would expose us to legal liability.

Termination by DQE. We may terminate your Account for a material breach that is not cured within 10 days after notice, or immediately for a breach of Section 6, 7 or 8. We may also terminate for convenience on 30 days' notice, in which case we will refund the unused portion of your Purchased Credits. We may close Accounts that have been inactive for an extended period after giving notice to the Account email.

Effect. On termination your license ends, unused Free Credits are forfeited, and unused Purchased Credits are forfeited if we terminated for your breach. Customer Data is not retained (Section 9); account data is handled as described in the Privacy Policy. Sections 5 (amounts owed), 7, 8, 9, 11, 12, 13, 14, 15, 17, 18 and 20 survive termination.

Talk to us first. Before starting arbitration or a lawsuit, send a written description of the dispute to legal@dqverify.com; we will send ours to your Account email. The parties will try in good faith to resolve the dispute for 30 days after the notice.

Binding arbitration. If the dispute is not resolved within 30 days, it will be resolved by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules, or its Consumer Arbitration Rules if the AAA determines that they apply. The Federal Arbitration Act governs this Section. The seat of arbitration is Miami-Dade County, Florida; hearings may be held by videoconference at either party's request. The arbitrator decides all issues, including the scope and enforceability of this Section, except that a court, not the arbitrator, decides whether the class-action waiver is enforceable. The arbitrator may award any relief a court could award to an individual party. Judgment on the award may be entered in any court of competent jurisdiction.

Exceptions. Either party may (a) bring an individual claim in small-claims court if it qualifies, and (b) seek an injunction or other equitable relief in court to protect intellectual property, confidential information, or against misuse of USPS Data or the Service.

Class-action waiver. EACH PARTY MAY BRING CLAIMS ONLY IN ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, CONSOLIDATED OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate claims of more than one party. If this waiver is found unenforceable for a claim, that claim must be brought in court under Section 18, and this Section otherwise remains in effect.

Opt-out. You may opt out of this arbitration agreement and class-action waiver by emailing legal@dqverify.com within 30 days after you first accept these Terms, stating your name, Account email and that you opt out of arbitration. Opting out does not affect any other part of these Terms.

Jury waiver. To the extent a claim proceeds in court, each party waives a jury trial where permitted by law.

These Terms are governed by the laws of the State of Delaware and applicable federal law, without regard to conflict-of-laws rules. For any dispute that is not subject to arbitration under Section 17, the state and federal courts in Miami-Dade County, Florida have exclusive jurisdiction, and each party submits to that jurisdiction.

We may update these Terms. We will post the updated Terms on this page with a new effective date and, for material changes, notify Account holders by email at least 30 days before the change takes effect. Changes to Section 17 do not apply to a dispute that either party had notice of before the change took effect. Your continued use of the Service after the effective date means you accept the updated Terms. If you do not agree, stop using the Service and close your Account before the effective date.

• Export, sanctions and lawful use. You must comply with US export control and sanctions laws and must not use the Service if you are on a US government restricted-party list or located in an embargoed country.
• Government users. The Service is commercial computer software and documentation; US government users receive only the rights granted to all customers under these Terms.
• Assignment. You may not assign these Terms without our written consent. We may assign them to an affiliate or to a successor in a merger, acquisition or sale of assets.
• Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control, other than payment obligations.
• Notices. Notices to DQE go to legal@dqverify.com or to DQE LLC, 1200 Brickell Ave, Ste 1960, Miami, FL 33131. Notices to you go to your Account email.
• Entire agreement. These Terms, the Privacy Policy, the Cookie Policy and any Enterprise order form are the entire agreement about the Service. If an order form conflicts with these Terms, the order form controls for that order.
• Severability and waiver. If a provision is unenforceable, the rest remains in effect. A failure to enforce a provision is not a waiver.
• Relationship. The parties are independent contractors. There are no third-party beneficiaries, except that USPS may enforce Section 8.
