Look for a field labeled for an invitation code, promo code, or similar during the address verification or service activation screens. Enter the full code exactly as it appears on your invitation, paying attention to capitalization and any hyphens. Submit the form to apply the code. The site will confirm if the code is valid and associate it with your account and mailing address. If you already maintain a USPS.com account, sign in first. Navigate to the Informed Delivery dashboard or enrollment section from your account menu. An option to enter an invitation code may appear if you have not fully activated the service for your address, or it may be accessible under account preferences or promotional offers. ## Completing Enrollment After Entering the Code After the code is accepted, finish verifying your mailing address. USPS typically requires confirmation that you receive mail at that location. This can involve selecting the correct address from a list of matches or waiting for a physical confirmation piece if automated matching fails. Once verified, Informed Delivery begins displaying daily mail previews for eligible letter mail and package tracking updates. You can manage notification preferences, such as email or text alerts, from the same dashboard. The service works best when your address is residential and within the contiguous United States, though availability depends on local mail processing capabilities.
## What to Do If the Code Field Does Not Appear Some users never see an invitation code prompt because their address is already eligible for standard enrollment or because the invitation has expired. In these cases, simply proceed with regular signup steps. The absence of a code field does not prevent access to Informed Delivery. If your invitation materials include a unique URL or QR code, scanning or visiting that link may pre-fill the code automatically and take you straight to the relevant page. Double-check that you are logged into the correct USPS.com account associated with the address on the invitation. Codes are usually tied to a specific household address and cannot be transferred. ## Troubleshooting Entry Problems If the site rejects the code, confirm that you typed it without extra spaces and that it has not already been used. Codes are single-use and time-limited. Clear your browser cache or try a different browser if the page fails to load the entry field. Mobile users should ensure they are on the full website rather than a limited app view, as some account features appear only in the browser version. For persistent issues, use the contact or help options available on the Informed Delivery site itself. USPS support can verify code status when you provide the invitation details and your account information. Do not share the full code publicly or with unofficial services.
## Alternative Ways to Locate Enrollment Help If you cannot find the entry point after following the steps above, return to the main USPS.com homepage and search for “Informed Delivery” using the site’s search bar. This reliably surfaces the official enrollment page and related FAQs. Local Post Office staff can also direct you to the correct online process but cannot enter codes on your behalf. Once enrolled, check the dashboard regularly for mail images, package notifications, and any additional service options such as mailpiece hold or package intercept requests. The service remains free and can be paused or canceled at any time through the same account portal.
