How This FIPS Code Works

02 220
02 = State FIPS (Alaska)
220 = County FIPS

Using FIPS Code 02220 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 02220
import requests

url = "https://api.census.gov/data/2022/acs/acs5"
params = {
    "get":  "NAME,B19013_001E,B01003_001E",
    "for":  "county:220",
    "in":   "state:02",
    "key":  "YOUR_CENSUS_API_KEY",
}
r = requests.get(url, params=params)
data = r.json()  # [[header...], [Sitka City and Borough, Alaska, income, pop, ...]
SQL — filtering by county FIPS 02220
-- 5-digit combined FIPS (state + county)
SELECT * FROM your_table WHERE county_fips = '02220';

-- Some datasets store state and county separately
SELECT * FROM your_table
WHERE state_fips = '02'
  AND county_fips = '220';

-- ⚠ Never cast to integer — leading zeros are lost:
-- county_fips = 2220 is WRONG for this county
R — tidycensus 02220
library(tidycensus)

get_acs(
  geography = "county",
  variables = c(income = "B19013_001E", pop = "B01003_001E"),
  state     = "02",
  county    = "220",
  year      = 2022
)
Zero-padding reminder: FIPS codes must always be stored and compared as zero-padded strings. 02 (not 2) and 220 (not 220) — losing the leading zeros is one of the most common data-join bugs in federal datasets. Full guide →
