Oklahoma City ZIP code footprint
How Oklahoma City's ZIP footprint compares with national norms.
12 ZIP codes are listed for Oklahoma City, covering a population of 702,767. They span 26 numbers, 73102 through 73127. The median covered metro on this site lists 12 codes; Oklahoma City ranks 2 of 94 by count. Large metros carry more codes because USPS splits a delivery area once carrier volume outgrows one route cluster, not because the city is geographically bigger.
All 12 codes share the 731 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Oklahoma City passes through one facility. The range runs 73102 to 73127.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Oklahoma redraws tax and municipal lines on a different schedule entirely. A Oklahoma City mailing address does not prove an address sits inside Oklahoma City city limits, and a single code can straddle the boundary.

Why ZIP-based rate lookup is unreliable
USPS redraws ZIP codes when carrier routes change. Tax jurisdictions move with annexations, county lines and voter-approved districts. The two never line up. In Oklahoma, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Oklahoma Tax Commission lookup at the time of sale.
