How This FIPS Code Works

08 065
08 = State FIPS (Colorado)
065 = County FIPS

The 5-digit FIPS code 08065 is formed by combining the 2-digit state identifier 08 (Colorado) with the 3-digit county identifier 065. Together they uniquely identify Lake County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Census ACS API — Python 08065
import requests

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

SQL — filtering by county FIPS 08065
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '08065';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '08'
  AND county_fips = '065';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 8065 is WRONG for this county

)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 08 (not 8) and 065 (not 65) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

ZIP Codes in Lake 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 Lake County. Why FIPS ≠ ZIP →
