Reading a Oklahoma ZIP code
Oklahoma holds 765 ZIP codes between 73001 and 74966, spread over 77 counties. Oklahoma City leads the state with 76 codes, ahead of Tulsa with 52. Every code here opens with the digit 7: that opening number is the national postal region Oklahoma 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 Oklahoma City spreads across 76 codes while some rural codes cross county lines.
