If your address is showing as "undeliverable" in the application, this may be because your address is not found in the USPS database.
We use USPS for address verification. If your address is showing as undeliverable, we suggest contacting the USPS Address Management Systems office to let them know that your street number, street name, apartment or suite number, and City, State, and ZIP Code are not listed in our national database correctly.
