Indianapolis ZIP codes: US ZIP code list for Indianapolis, Indiana (IN)

Quick answer

Indianapolis, Indiana has 12 US ZIP codes, running 46201 to 46227 inside Marion County. Each carries the same 7% combined sales tax rate. 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.

Indianapolis ZIP code footprint

How Indianapolis's ZIP footprint compares with national norms.

12 ZIP codes are listed for Indianapolis, covering a population of 879,293. They span 27 numbers, 46201 through 46227. The median covered metro on this site lists 12 codes; Indianapolis 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 462 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Indianapolis passes through one facility. The range runs 46201 to 46227.

ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Indiana redraws tax and municipal lines on a different schedule entirely. A Indianapolis mailing address does not prove an address sits inside Indianapolis 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 Indiana, even without local add-ons, remote sellers should validate the full delivery address against the Indiana Department of Revenue lookup at the time of sale.

What is the first ZIP code in Indianapolis, IN?
