How This FIPS Code Works

16 027
16 = State FIPS (Idaho)
027 = County FIPS

The 5-digit FIPS code 16027 is formed by combining the 2-digit state identifier 16 (Idaho) with the 3-digit county identifier 027. Together they uniquely identify Canyon County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 16027
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:027",
    "in":   "state:16",

SQL — filtering by county FIPS 16027
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '16027';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '16'
  AND county_fips = '027';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 16027 is WRONG for this county
R — tidycensus 16027

get_acs(
  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),
  state     = "16",
  county    = "027",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 16 (not 16) and 027 (not 27) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Canyon County

ZIP codes do not align perfectly with county boundaries — a single ZIP code can span multiple counties, and a county can contain parts of many ZIP codes. The ratios below (from the Census 2020 ZCTA relationship file) show the land area share of each ZCTA that falls within Canyon County. Why FIPS ≠ ZIP →
