Sioux Falls ZIP code footprint
How Sioux Falls's ZIP footprint compares with national norms.
7 ZIP codes are listed for Sioux Falls, covering a population of 202,078. They span 8 numbers, 57103 through 57110. The median covered metro on this site lists 12 codes; Sioux Falls ranks 78 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 7 codes share the 571 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Sioux Falls passes through one facility. The range runs 57103 to 57110.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; South Dakota redraws tax and municipal lines on a different schedule entirely. A Sioux Falls mailing address does not prove an address sits inside Sioux Falls 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 South Dakota, local jurisdictions set their own increments, so remote sellers should validate the full delivery address against the South Dakota Department of Revenue lookup at the time of sale.
