Fix Zip Code Notification For Free

The confirmation number is the 16-digit code printed on the confirmation letter sent to your new address. If you submitted your USPS address change order online, the code is in the confirmation email that you received.

Usually what happens is a carrier or post master from the office where the package is sent will correct the zip code by looking at the address and even reach out to that particular post office to ensure the package is delivered to the correct address.

Without the Code, you'll have to visit a Post Office to change or cancel your COA order. If you submitted your Change of Address (COA) online, you will receive the MVL and CNL mentioned above. Additionally, you will also receive a Change of Address Confirmation via email containing the Confirmation Code.

Invalid zip code error is displayed when attempting to process a payment from your customer with a billing address outside the U.S. They may have a ZIP code (or Province code) that includes characters that do not meet the U.S. 5 digit standard.

What should I do if I am not yet receiving mail at my new address? If it is more than ten days after the start date of your move and no mail has arrived, call 1-800-ASK-USPS (1-800-275-8777).

After you submit an Official Change of Address (online at moversguide.usps.com, in-person at a Post Office?, or through your mail carrier), you will receive an email and a physical letter with a 9-digit alpha-numeric code requesting confirmation of your change of address.
