How This FIPS Code Works

16 085
16 = State FIPS (Idaho)
085 = County FIPS

The 5-digit FIPS code 16085 is formed by combining the 2-digit state identifier 16 (Idaho) with the 3-digit county identifier 085. Together they uniquely identify Valley County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 16085
import requests

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

    "in":   "state:16",

SQL — filtering by county FIPS 16085
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16085';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '085';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16085 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 16 (not 16) and 085 (not 85) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Valley County
