How This FIPS Code Works

33 007
33 = State FIPS (New Hampshire)
007 = County FIPS

Census ACS API — Python 33007
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",

SQL — filtering by county FIPS 33007
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '33007';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '33'
  AND county_fips = '007';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 33007 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 33 (not 33) and 007 (not 7) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Coos County
