• State FIPS: 22
• Capital: Baton Rouge

Louisiana has parishes rather than counties — the Census returns parish equivalents (e.g. East Baton Rouge Parish). The county FIPS column works the same way.

FAQ

What county is Baton Rouge, Louisiana in?

The example above — 900 N 3RD ST, BATON ROUGE, LA, 70802 — falls in East Baton Rouge Parish (FIPS 22033).

Which congressional district covers Louisiana?

Congressional districts are numbered per state; the GEOID is the state FIPS (22) plus the district number. Run any Louisiana address through the tool to get its current district, senatorial and house/assembly districts in one pass.

Does this work for the whole state?

Yes — the tool covers all of Louisiana. The Census Geocoder needs a street address (PO Boxes return NO_MATCH); misspellings and wrong ZIPs are usually auto-corrected.

Is it free?

Yes — up to 100 addresses per run on the free plan, powered by the free official Census Geocoder. A one-time $9 credit pack raises the limit to 1,000 addresses per run.
