Bénin
Classification (as of 14 October 2026): C — National digital addressing system exists, is being rolled out or is being legislated
Benin has no postcode; in April 2026 the Council of Ministers authorised a national digital, geolocated street-and-door addressing strategy, starting in Greater Nokoué and Parakou.
World Bank estimate: 46.6% of the population lived in rural areas in 2025.

WIA Pin Code turns GPS coordinates into a 12-digit code (XXX-XXX-XXX-XXX) for any point on Earth. Each code identifies a cell of about 20 m north–south × 40 m east–west at the equator (narrower towards the poles). The first nine digits are the earlier v1 code, so existing v1 codes remain the prefix of the new code. The code is calculated from coordinates alone, so conversion works without an internet connection (maps and search need one). It is free for governments and individuals, and is meant to complement, not replace, Benin's own addresses, postcodes and address systems.
function yujinTransform(lat, lng) {
const latStr = String(Math.floor(((lat + 90) / 180) * 999999)).padStart(6, '0');
const lngNorm = (lng + 180) / 360;
const lngBase = Math.floor(lngNorm * 999);
const lngSub = Math.floor((lngNorm * 999 - lngBase) * 1000);
return latStr.slice(0,3) + '-' + latStr.slice(3,6) + '-' + String(lngBase).padStart(3,'0') + '-' + String(lngSub).padStart(3,'0');
