Reading a Arizona ZIP code
Arizona holds 530 ZIP codes between 85001 and 86556, spread over 15 counties. Phoenix leads the state with 77 codes, ahead of Tucson with 54. Every code here opens with the digit 8: that opening number is the national postal region Arizona 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 Phoenix spreads across 77 codes while some rural codes cross county lines.
