Reading a Rhode Island ZIP code
Rhode Island holds 90 ZIP codes between 02801 and 02940, spread over 5 counties. Providence leads the state with 12 codes, ahead of Warwick with 4. Every code here opens with the digit 0: that opening number is the national postal region Rhode Island 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 Providence spreads across 12 codes while some rural codes cross county lines.
