What Verify & Confirm™ Does
Verify & Confirm™ is a real-time address validation platform that helps organizations ensure mailing and shipping data is accurate before items are sent. By detecting change-of-address records and validating delivery information instantly, the system prevents costly delivery failures and returned mail.

Verify & Confirm™ allows organizations to check addresses individually or in batches, ensuring shipments and mailings reach the intended destination the first time.
The platform integrates easily with existing applications and workflows through a RESTful API, allowing businesses to validate address data automatically during mailing preparation, order fulfillment, or customer data entry.

Frequently Asked Questions
What does Verify & Confirm™ do?
Verify & Confirm™ validates addresses in real time and detects change-of-address records so mail and shipments are sent to the correct, current location. It's designed to catch bad or outdated addresses before they cause a failed delivery.
Can Verify & Confirm™ integrate with existing systems?
Yes, Verify & Confirm™ offers a RESTful API that lets developers integrate address validation directly into applications, CRMs, billing systems, and shipping workflows. This allows address checks to run automatically at data entry, checkout, or mail preparation instead of as a separate manual step.
Can Verify & Confirm™ process large volumes of address data?
Yes, Verify & Confirm™ supports both single-record lookups and batch processing, making it suitable for enterprise-scale mailing and shipping operations. Organizations can validate one address during a live transaction or clean an entire database in a single batch run.
Why is real-time address validation important?
Real-time validation ensures an address reflects the most current delivery information at the moment it's captured, rather than relying on data that may already be outdated. This reduces returned mail, failed deliveries, and the operational costs of reshipping or remailing.
Does Verify & Confirm™ detect change-of-address records?
Yes, Verify & Confirm™ detects change-of-address (COA) records so businesses know when a customer or recipient has moved. Since millions of people file change-of-address requests every year, this detection keeps delivery data current without manual follow-up.
How fast is Verify & Confirm™'s API response time?
Verify & Confirm™ is built for ultra-fast response times, allowing address checks to run inline within live systems without noticeable delay. This speed makes it practical to validate addresses during checkout, form submission, or order processing in real time.
Can Verify & Confirm™ validate a single address or only batches?
Verify & Confirm™ supports both: it can validate one address instantly through a single API call or process large batches of addresses at once. This flexibility covers use cases from a real-time checkout form to a full database cleanse.
What's the difference between Verify & Confirm™ and MailPreparer®'s address cleansing?
MailPreparer® cleanses and standardizes entire mailing lists as part of USPS presort preparation, while Verify & Confirm™ is a standalone, real-time API for validating addresses at the point of capture, such as checkout or CRM entry. Many organizations use both together: Verify & Confirm™ to keep data clean continuously, and MailPreparer® to prepare the resulting lists for postal submission.
Does Verify & Confirm™ reduce returned mail and packages?
Yes, by validating addresses and flagging change-of-address records before items ship, Verify & Confirm™ reduces the volume of mail and packages returned as undeliverable. Fewer returns mean lower reshipping costs and a better delivery experience for recipients.
Can Verify & Confirm™ be used during customer data entry, not just before mailing?
Yes, because Verify & Confirm™ integrates via a RESTful API, it can validate addresses the moment a customer enters them, such as during account signup or checkout, rather than only in a pre-mailing batch. Catching bad addresses at entry prevents inaccurate data from ever reaching downstream mailing and shipping systems.
Does Verify & Confirm™ include change-of-address detection similar to NCOALink-based competitors?
Yes, Verify & Confirm™ detects change-of-address records in the same way that NCOALink-based tools from vendors like AccuZip and Melissa flag moved recipients. This lets organizations update delivery data automatically instead of relying solely on static address correction.
