How This FIPS Code Works

06 029
06 = State FIPS (California)
029 = County FIPS

The 5-digit FIPS code 06029 is formed by combining the 2-digit state identifier 06 (California) with the 3-digit county identifier 029. Together they uniquely identify Kern County in every US federal dataset. No two counties share the same 5-digit FIPS code.

Using FIPS Code 06029 in Code

Common patterns for querying federal datasets by this county's FIPS code. The leading zeros are significant — always treat FIPS codes as strings, not integers.

Census ACS API — Python 06029
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:029",
    "in":   "state:06",
    "key":  "YOUR_CENSUS_API_KEY",
}
r = requests.get(url, params=params)
data = r.json()  # [[header...], [Kern County, California, income, pop, ...]
SQL — filtering by county FIPS 06029
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '06029';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '06'
  AND county_fips = '029';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 6029 is WRONG for this county
R — tidycensus 06029

get_acs(
  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),
  state     = "06",
  county    = "029",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 06 (not 6) and 029 (not 29) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →

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