How does the free trial work?

Sign up with a business email and you get 100 free credits for 14 days. No credit card is needed. You can run address, email, and phone checks on real records through the API or a CSV upload.

How much does DQVerify cost after the trial?

Credits are sold as one-time packs, starting at $700 for 20,000 credits. There is no subscription and nothing renews automatically. Paid credits are valid for 12 months from purchase. Each check uses one credit per module, so verifying an address, email, and phone for one record uses three credits.

Do you store the data I verify?

No. Validation inputs are processed in real time and are not retained once your request completes. Batch results are available to download during your session. Email, phone, and international address validation run on infrastructure of our affiliate DQE Software SAS in the European Union (France).

Does DQVerify use USPS CASS Certified software?

Yes. US addresses are processed with USPS CASS Certified software supplied by a USPS licensee. The certification belongs to that software, not to DQVerify. Each US check corrects and returns the ZIP+4, confirms deliverability with USPS DPV, and returns the address in standardized form with a result code that says whether it is valid as entered, was corrected, or is missing something such as a street number or unit.

Can I verify addresses outside the US?

Yes. Address validation covers 240+ countries and territories with the same API key, using licensed postal authority data. CASS is a US-only standard, so it applies to US addresses only.

Does it work with Salesforce and Shopify?

Yes. DQVerify is listed on Salesforce AppExchange and the Shopify App Store, and DQE, our parent company, is a Salesforce ISV Partner. Records can be validated as they are created, with no exports or imports.
