USPS Address Help

The IRS uses the United States Postal Service (USPS) addresses and so for some this may be the issue if it tells you the address is not found. Use this USPS address help to assist with troubleshooting.

For example if you enter 1001 East Chestnut Expressway, Springfield, MO 65802 it might not recognize the address because the USPS has the address as 1001 E Chestnut EXPY, Springfield, MO 65802-3625.
