Reading a Arkansas ZIP code
Arkansas holds 706 ZIP codes between 71601 and 72959, spread over 75 counties. Little Rock leads the state with 25 codes, ahead of Fort Smith with 13. Every code here opens with the digit 7: that opening number is the national postal region Arkansas 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 Little Rock spreads across 25 codes while some rural codes cross county lines.
