Quick answer

ZIP boundaries are postal delivery routes, not tax boundaries — a code that crosses a city or district line can hold more than one rate, so destination-based sellers should validate by full street address.

Cincinnati ZIP code footprint
How Cincinnati's ZIP footprint compares with national norms.
12 ZIP codes are listed for Cincinnati, covering a population of 311,097. They span 28 numbers, 45202 through 45229. The median covered metro on this site lists 12 codes; Cincinnati 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 452 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Cincinnati passes through one facility. The range runs 45202 to 45229.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Ohio redraws tax and municipal lines on a different schedule entirely. A Cincinnati mailing address does not prove an address sits inside Cincinnati 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 Ohio, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Ohio Department of Taxation lookup at the time of sale.
