How to Reauthorize Your UPS Account

UPS is upgrading to a new security protocol called OAuth 2.0, which requires all shipping platforms with a UPS connection to reauthenticate their accounts. To avoid service disruptions and continue using your UPS account for label creation, rate comparisons, and other functionalities within Endicia, please complete the reauthentication process by August 5, 2024.

Reauthorization Only Required for Connected UPS Accounts

The steps in this article are only required to reauthorize your own connected UPS account and do not apply to UPS from Endicia. If you only ship UPS using UPS from Endicia, no action is required at this time.

Get Started

To complete the required changes, you will need the following information that is associated with the UPS account number you have configured in Endicia:

  • UPS.com username or email account login

  • Password for the account

  • Please note that additional information is required if you also use UPS Mail Innovations.

Reauthorize Your UPS account(s) in Stamps.com

  1. Go to Settings and select Carriers.

  2. Select UPS from the carriers list and click Edit.

  3. Enter the ZIP code associated with your UPS account number shown in the top right.

  4. Click Authenticate with UPS. This will redirect you to the UPS website to complete authentication.

  4. Click the Add button

  5. Select Documents and Packages as Payment Account Type and enter the Account Number, Nickname, and select the Country associated with the account. Then click the Next button.

  6. Open the Account Verification Method page and select Pin Verification. A PIN will be sent to the email associated with the account for verification.

  7. Select I already have a pin once that email is received and enter the pin and email associated with the account, then click the Next button.
