How This FIPS Code Works

16 005
16 = State FIPS (Idaho)
005 = County FIPS

The 5-digit FIPS code 16005 is formed by combining the 2-digit state identifier 16 (Idaho) with the 3-digit county identifier 005. Together they uniquely identify Bannock County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 16005
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:005",
    "in":   "state:16",

SQL — filtering by county FIPS 16005
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16005';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '005';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16005 is WRONG for this county

get_acs(
  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),

  county    = "005",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 16 (not 16) and 005 (not 5) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Bannock County
