How This FIPS Code Works

01 055
01 = State FIPS (Alabama)
055 = County FIPS

The 5-digit FIPS code 01055 is formed by combining the 2-digit state identifier 01 (Alabama) with the 3-digit county identifier 055. Together they uniquely identify Etowah County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 01055
import requests

SQL — filtering by county FIPS 01055
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '01055';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '01'
  AND county_fips = '055';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 1055 is WRONG for this county

Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 01 (not 1) and 055 (not 55) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
