How can we help?

USPS Address Validator and Standardization


Streamline your physical mail by ensuring addresses are legitimate and properly formatted.

The USPS Address Validator and Standardization tools allow you to both validate an address can receive mail and format it properly to help it arrive more reliably. You can use both tools within a customer's page in LMS, either when entering their address or on the customer tools tab.

USPS Address Validator

Clicking validate will submit a request through our integration with the USPS database to check if the provided address is a USPS deliverable mailing address. If the address is found in the USPS database, the Verify icon will change to a check mark. If the address is not found, an error will be displayed with a red X.

It's important to note that while this feature can ensure that an address is legitimate, it cannot guarantee that your customer actually lives there.

USPS Address Standardization

Clicking this standardizes the address to match the USPS's formatting; this helps keep your data clean and prevent lost mail. Here's an example of an address that doesn't quite match USPS formatting:

1600 Pennsylvania Ave NW

Washington DC 20500 USA

After USPS standardization, it will look more like this:

1600 PENNSYLVANIA AVE NW

WASHINGTON DC 20500-0003 USA

If you click ‘Save’, then it will update the Customer address that you’ve verified to the standardized address with its formatting.
