Quick answer

St. Paul, Minnesota has 11 US ZIP codes, running 55101 to 55119 inside Ramsey County. Each carries the same 9.875% 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.

St. Paul ZIP code footprint

How St. Paul's ZIP footprint compares with national norms.

11 ZIP codes are listed for St. Paul, covering a population of 303,176. They span 19 numbers, 55101 through 55119. The median covered metro on this site lists 12 codes; St. Paul ranks 54 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 11 codes share the 551 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to St. Paul passes through one facility. The range runs 55101 to 55119.

ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Minnesota redraws tax and municipal lines on a different schedule entirely. A St. Paul mailing address does not prove an address sits inside St. Paul 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 Minnesota, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Minnesota Department of Revenue lookup at the time of sale.
