Nigerian conventions

Address formats

Nigerian addresses are descriptive, postcodes are rarely known, and landmark fields are not optional decoration.

The shape of a Nigerian address#

A usable Nigerian address form collects:

  1. Street address — house number and street, free text, generous length
  2. Nearest landmark — optional but prominent; this is how deliveries actually succeed
  3. City / town
  4. Local Government Area (LGA) — dropdown, filtered by state
  5. State — dropdown of the 36 states + FCT

Postcodes#

Nigeria has postcodes; almost nobody knows theirs. Never make postcode a required field. If a partner system demands one, derive it from the LGA behind the scenes.

Do

Nearest landmark (optional) — e.g. "opposite Mobil filling station"

Don't

Postcode (required)

Writing addresses back#

Display addresses in the order users say them: street, landmark, city, LGA, state. Don't reformat into a foreign envelope layout.

Abbreviations#

Spell out "Street", "Road", "Close" and "Crescent" in stored data; accept any abbreviation in input. "FCT" and "Abuja" should both resolve to the Federal Capital Territory.
