Milsat built the geospatial backbone of Nigeria's 11-character digital postcode

As first reported by TechCabal, Nigerian start-up Milsat Technologies, founded in 2017, is the technical partner behind the National Digital Alphanumeric Postcode, which the Nigerian Postal Service (NIPOST) launched on 1 October 2026. The system gives each addressable building an 11-character code, replacing the older six-digit numeric postcodes that pointed only to an area. TechCabal reports that Milsat's work with NIPOST began towards the end of 2021 and included a pilot in Abuja.

Space in Africa's analysis describes the production chain. Satellite imagery was processed automatically into basemaps and sent to more than 25,000 field agents in under 15 minutes. Agents then mapped buildings and roads door to door in under nine months, recording structure type, use and ownership. NASRDA, the National Population Commission and the Surveyor General's office supported the work.

NIPOST now manages the dataset from a GIS lab. Access is through an app, web finder, API, SDKs and bulk data. Updates are request-driven: users suggest edits or request codes for new buildings, and NIPOST reviews each submission. Open issues include accuracy in dense areas, owners' names appearing in address records, and hosting. NIPOST says AWS serves the public website but does not hold the master records, and that contractors such as Milsat have only controlled access.

Why it matters: Nigeria now has a national building-level address layer that surveyors, planners and GIS teams can integrate through an API and bulk data. Its value depends on coverage, how quickly it tracks new construction, and where the data is hosted and governed.
