What Is Usps User Id

Your USPS Web Tools user ID is a combination of letters and numbers, for example 123ABCDE1234 , that is automatically generated by USPS. The user ID gives you access to package tracking, rate, and service delivery standards APIs with USPS when you register.

How do I find my USPS user ID?

If you forgot your username, you can retrieve it by going to the USPS.com Account sign-in page, and select “Forgot your username?” Enter the email address associated with your account to have your username emailed to you.

Why can't I create a USPS account?

To resolve this issue, you’ll want to ensure that you’re using a physical ship from address; this does not have to match your billing address. If you are using a PO box or have an address that does not receive mail delivery, then you’ll want to use the address of your Post Office where you drop off your mail.
