What you can build

State → LGA → ward dropdownsRegistration and address forms where each dropdown depends on the one before. Plain HTML, React or Django.

Phone number fieldsAccept every way people type a number, store +234…, and explain why a number is invalid.

Bank account formsBank dropdowns and the CBN check digit, to catch a mistyped account number before you pay.

Senate, Reps and AssemblyWho represents an LGA or ward: INEC's 109 districts, 360 federal and 990 state constituencies.

Search and autocompleteFind places even with typos, old spellings and accents: lagso, Yenegoa, Ọ̀yọ́, AMAC.

Vehicle platesCheck and format standard and dealer plate numbers from the Road Traffic Regulations.

Why naija-data

Every record has a source

INEC, the Constitution, the CBN, the NCC and the Official Gazette, each recorded with URL, date and licence. Values from a single source are flagged. See the sources.

Errors in official lists, caught

Cross-checking found a duplicated INEC ward, typos in official names, duplicated constituency codes and banks sharing a code. Each is documented. Coverage and gaps.

Same answers everywhere

Python, JavaScript, Go and the API come from one dataset, and over 13,000 shared tests check that they agree, down to the search scores.

Free and open

Code under MIT, data under CC BY 4.0: use it in commercial apps, just give credit. No API key, no sign-up.
