Verify Customer Address

This request allows you to use the USPS's address verification service to determine an address's legitimacy.


This request uses LoanPro's integration with the USPS database to check if the provided address is a USPS deliverable mailing address. Address verification is an important piece of lending as it provides lenders a way to contact borrowers if they fall behind on their payments. Here's what you need to know about address verification:

  • USPS's verification service works via Connections—LoanPro's hub for integrations—and it needs to be configured within your account.
  • This feature can ensure an address is legitimate, but it cannot guarantee that a customer actually resides there.
  • If you use this service via the API, pay special attention to the responses you receive; the responses will provide useful information.

For an example of how address verification works within the UI, see our USPS Address Verify & Validate article.

Alternative Method

There is an alternative way to send an address verification request. While the setup above uses the customer ID, you can use an address ID if you send a POST request to the following endpoint:{AddressID})/verify
