Quick answer
St. Petersburg, Florida has 10 US ZIP codes, running 33701 to 33714 inside Pinellas 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.

St. Petersburg ZIP code footprint
How St. Petersburg's ZIP footprint compares with national norms.
10 ZIP codes are listed for St. Petersburg, covering a population of 261,256. They span 14 numbers, 33701 through 33714. The median covered metro on this site lists 12 codes; St. Petersburg ranks 55 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 10 codes share the 337 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to St. Petersburg passes through one facility. The range runs 33701 to 33714.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Florida redraws tax and municipal lines on a different schedule entirely. A St. Petersburg mailing address does not prove an address sits inside St. Petersburg 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 Florida, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Florida Department of Revenue lookup at the time of sale.
