A tool for looking up FIPS county codes.

Example

const fips = require('fips-county-codes');

fips.get({
  "state": "AL",
  "county": "Chambers"
});

// {
//   "state": "AL",
//   "county": "Chambers",
//   "countyfp": "015",
//   "fips": "01015"
// }

fips.get({
  "fips": "017",
  "state": "MD"
});

// {
//   "state": "AL",
//   "county": "Charles County",
//   "countyfp": "017",
//   "fips": "24017"
// }

fips.getByCountyAndState('MD', 'Anne Arundel');

// {
//   "state": "MD",
//   "county": "Anne Arundel County",
//   "countyfp": "003",
//   "fips": "24003"
// }

fips.getByFipsAndState('006', 'MD');

// {

Source

U.S. Census Bureau (2010). Here is the CSV data for all of the United States.

Data manipulation

The only change I made to the dataset was to include a header row in the CSV file; I use csv2json to convert dataset to JSON. I did not attempt to change types. All fields are of type String.

Field descriptions

| Field Name | Field Description | Example | | ---------- | ----------------- | -------------- | | state | State Postal Code | FL | | statefp | State FIPS Code | 12 | | countyfp | County FIPS Code | 011 | | countyname | County name | Broward County | | classfp | FIPS Class Code | H1 |

FIPS Class Codes

• H1: identifies an active county or statistically equivalent entity that does not qualify under subclass C7 or H6.
• H4: identifies a legally defined inactive or nonfunctioning county or statistically equivalent entity that does not qualify under subclass H6.
• H5: identifies census areas in Alaska, a statistical county equivalent entity.
• H6: identifies a county or statistically equivalent entity that is areally coextensive or governmentally consolidated with an incorporated place, part of an incorporated place, or a consolidated city.
• C7: identifies an incorporated place that is an independent city; that is, it also serves as a county equivalent because it is not part of any county, and a minor civil division (MCD) equivalent because it is not part of any MCD.
