Quick answer
Austin, Texas has 12 US ZIP codes, running 78701 to 78759 inside Travis County. Each carries the same 8.25% 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.

Austin ZIP code footprint
How Austin's ZIP footprint compares with national norms.
12 ZIP codes are listed for Austin, covering a population of 979,882. They span 59 numbers, 78701 through 78759. The median covered metro on this site lists 12 codes; Austin 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 787 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Austin passes through one facility. The range runs 78701 to 78759.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Texas redraws tax and municipal lines on a different schedule entirely. A Austin mailing address does not prove an address sits inside Austin 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 Texas, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the Texas Comptroller of Public Accounts lookup at the time of sale.
