That is incorrect. The UAD requires the
physical address to be entered in a
format that conforms to the USPS...The UAD does not require the address to match some so-called official USPS address.
Here is the applicable section of the UAD spec (appendix D):
Property Address, City, State, ZIP Code
The appraiser must enter the physical property address in a format that conforms to the United States Postal Service (USPS) address standards in Publication 28 – Postal Addressing Standards (pub28) for complete addresses. Address standards can be found at USPS.gov. The subject address must be populated consistently throughout the form.
Please keep in mind that many zip codes allow for the use of more than one city name - zip codes can be looked up here:
