## Receiving and Entering the Invitation Code Once you have requested the code, the physical letter from USPS typically arrives in your mailbox within three to ten business days. To complete your enrollment: 1. Open the letter to locate your unique alphanumeric activation code. 2. Log back into your personal account on the official USPS website. 3. Navigate to the Informed Delivery section or your account profile. 4. Enter the code exactly as it appears in the letter to activate the service.
Please note that these codes are time-sensitive. The letter will specify an expiration date, which is typically 30 days from the date the request was generated. If the code expires before you enter it, you will need to restart the enrollment process to request a new one. ## Alternative: Promotional Invitation Codes Occasionally, USPS sends promotional letters to addresses that are eligible for Informed Delivery but have not yet signed up. These mailers contain an invitation code to simplify the registration process. If you receive one of these promotional mailers:
1. Visit the web address provided on the mailer. 2. Sign in or create a USPS account. 3. Enter the invitation code printed on the mailer when prompted during the signup process to verify your address. ## What to Do If You Do Not Receive the Code If your mailed invitation code does not arrive within the expected timeframe, or if you encounter issues during the online request process, you have alternative options: * **Request a New Code:** You can log back into your USPS account and request that another letter be sent. This will invalidate the previous code. * **In-Person Verification:** Instead of waiting for a mailed code, you can opt for in-person identity verification. The USPS website will provide a list of participating local post office locations. You must bring a valid government-issued photo ID that matches your registration address to complete the process in person.
For any persistent issues or changes in eligibility, it is recommended to consult the official USPS Help and Support page or contact USPS customer service directly.
