How This FIPS Code Works

49 049
49 = State FIPS (Utah)
049 = County FIPS

SQL — filtering by county FIPS 49049
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '49049';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '49'
  AND county_fips = '049';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 49049 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 49 (not 49) and 049 (not 49) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Utah County

ZIP codes do not align perfectly with county boundaries — a single ZIP code can span multiple counties, and a county can contain parts of many ZIP codes. The ratios below (from the Census 2020 ZCTA relationship file) show the land area share of each ZCTA that falls within Utah County. Why FIPS ≠ ZIP →
