Reading a Alabama ZIP code
Alabama holds 811 ZIP codes between 35004 and 36925, spread over 67 counties. Birmingham leads the state with 62 codes, ahead of Mobile with 34. Every code here opens with the digit 3: that opening number is the national postal region Alabama 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 Birmingham spreads across 62 codes while some rural codes cross county lines.
