You cannot change your USPS.com username after you create it

USPS does not offer a way to edit or change the username you chose when you set up your account. Once you create a username, it stays the same for the life of that account. If you want a different username, you will need to create a new USPS.com account with the username you prefer.

This is different from your password, which you can change at any time from your account settings. Your username is the permanent identifier you use to log in, and USPS treats it as a fixed part of your account record. The distinction matters because many people assume usernames work like passwords — they do not.

Key Takeaways

  • USPS.com usernames cannot be changed once created, so you will need to create a new account if you want a different one.
  • You can change your password whenever you want through your account settings, but not your username.
  • Creating a new account means starting fresh with a new email address or phone number linked to it.
  • Any saved addresses, payment methods, or preferences in your old account will not transfer to a new one.
  • USPS customer service cannot change your username for you, even if you ask them directly.

What happens to your old account when you create a new one

If you create a new USPS.com account with a different username, your old account remains in the system but becomes inactive if you stop using it. You will not be able to merge the two accounts or move information from one to the other.

Any saved addresses, payment methods, or shipping history tied to your old account stays there. You will need to re-enter these details in your new account. If you have any pending shipments or mail holds connected to the old account, contact USPS directly to make sure those are handled before you switch over completely.

How to create a new USPS.com account with your preferred username

Go to USPS.com and click "Sign Up" or "Create Account" on the login page. You will be asked to enter an email address or phone number, a password, and your preferred username. Choose the username you want to use going forward. Take your time with this choice since you cannot change it later.

Complete the remaining steps, which include verifying your email or phone number and providing your name and address. Once your new account is active, you can log in with your new username. Keep your old account credentials in a safe place in case you need to reference anything from your old account later, such as past shipping records or payment history.

Why USPS locks usernames in place

USPS treats your username as a permanent account identifier tied to your shipping history, payment records, and account security. Allowing username changes would complicate their record-keeping and could create confusion if a username was reassigned to a different person.

This approach is common among government and financial websites, where account identifiers are kept stable to prevent fraud and maintain accurate records. It is less convenient than some commercial sites, but it reflects how USPS prioritizes account security and record integrity. The policy protects both you and the postal service from potential misuse.

Changing your password instead of your username

If you straightforward want to update your login credentials for security reasons, you can change your password without creating a new account. Log into USPS.com, go to your account settings, and look for "Password" or "Security Settings." You will be asked to enter your current password and then create a new one.

Changing your password is quick and keeps all your saved information, shipping history, and payment methods intact. Do this if your current password is weak, if you have shared it with someone, or if you want to use something more memorable. You only need to create a new account if you specifically want a different username.

What to do if you forgot your username

If you cannot remember your username, go to the USPS.com login page and click "Forgot Username?" or a similar link. You will be asked to enter the email address or phone number associated with your account, and USPS will send you a reminder of your username.

If you no longer have access to that email or phone number, contact USPS customer service by phone or through their website. Have your name, address, and any other account details ready to verify your identity. They can help you regain access to your account or discuss other options for recovering your information.
