Reading a Utah ZIP code
Utah holds 347 ZIP codes between 84001 and 84791, spread over 29 counties. Salt Lake City leads the state with 52 codes, ahead of Ogden with 13. Every code here opens with the digit 8: that opening number is the national postal region Utah belongs to, the next two digits name the sectional center that sorts the mail, and the final two point to the local office. A ZIP+4 suffix narrows delivery to a block face. Boundaries follow carrier routes rather than city limits, which is why Salt Lake City spreads across 52 codes while some rural codes cross county lines.
