Why does it say that I have not provided a valid address?

The AIUSA Action Center compares user addresses to the United States Postal Service (USPS) database.  If no match can be made between the address you provide and an address in the USPS database, then the system will report your address is invalid and will not allow you to proceed.

You can check your address at the USPS website at:

Please verify the spelling and the number of the address at the USPS website and try again.
