How This FIPS Code Works

35 017
35 = State FIPS (New Mexico)
017 = County FIPS

The 5-digit FIPS code 35017 is formed by combining the 2-digit state identifier 35 (New Mexico) with the 3-digit county identifier 017. Together they uniquely identify Grant County in every US federal dataset. No two counties share the same 5-digit FIPS code.

SQL — filtering by county FIPS 35017
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '35017';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '35'
  AND county_fips = '017';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 35017 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 35 (not 35) and 017 (not 17) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Grant County

The ratios below (from the Census 2020 ZCTA relationship file) show the land area share of each ZCTA that falls within Grant County. Why FIPS ≠ ZIP →
