For security reasons, this mailed activation code is only valid for a limited time—typically 30 days from the date the letter was generated. If you do not enter the code into your online account before this window closes, the code becomes invalid, and you must start the verification process again. ## How to Request a New Activation Code If your code has expired and you still want to complete your registration online, you can request a new letter. 1. Go to the official USPS website and log in to the personal account you created for Informed Delivery. 2. Navigate to the Informed Delivery enrollment page. 3. Select the option to request a new activation code. 4. Confirm that your mailing address is correct. 5. Submit the request.

USPS will generate a new letter with a new unique code and mail it to your address. This process usually takes three to ten business days. Once the new letter arrives, log back into your account immediately to enter the code before it expires. ## Verify Your Identity In Person If you do not want to wait for another letter to arrive in the mail, or if you have trouble requesting a new code online, you may be eligible to verify your identity in person. To use this method: * Log in to your USPS account and navigate to the Informed Delivery signup page. * Look for the option to verify your identity in person. * If eligible, the system will generate a mobile barcode and provide a list of participating Post Office locations near you. * Save the barcode to your phone or print it out. * Visit the designated Post Office and present the barcode along with a valid, government-issued photo ID. The address on your ID must match the address you are registering for Informed Delivery.

A postal employee will scan your barcode and verify your identity, which will activate your Informed Delivery account without the need for a mailed code. ## What to Do If You Cannot Request a New Code In some cases, the option to request a new code online may not be available. This usually happens if too much time has passed since your initial registration attempt, causing your sign-up session to expire completely. If this occurs, you will need to delete your pending enrollment or restart the registration process from the beginning. If the system prevents you from registering because your address is already associated with a pending account, you may need to contact USPS customer support or visit your local Post Office for assistance in clearing the old request.
