OPEN ADDRESS INFRASTRUCTURE · 54 COUNTRIES

Every place in Africa can have an address by tonight.

ADAS turns any GPS point into a nine-digit address that survives a phone call, works on a feature phone, prints as a QR plate, and validates offline. One system, borderless, built as open infrastructure — not another app.

SHEET 01 · ONE ADDRESS, THREE FORMS

SS-1794-15024

Spoken

Digits only — no letters to mishear across languages, accents, or scripts. Read it over any phone call, type it on any keypad.

▦ QR

Printed

A weatherproof plate on the gate. Any camera resolves it — no app required. Damaged plate? The digits underneath still work.

/a/SS1794

Linked

A URL you can drop in WhatsApp, an SMS, or an order form. The registry resolves it to a pin, a zone, and a verification status.

SHEET 02 · HOW IT WORKS

Zones follow people, not politics

Each country is cut into up to 10,000 zones by population — small in dense cities, vast in open land. Nearby zones share nearby numbers, so 1794 next to 1795 means next door, and zone numbers never change when districts are redrawn.

SS-1794-15024

A misheard digit fails loudly

The last digit is a checksum. Swap or mistype any digit and the code rejects during the phone call — not after a 30 km trip to the wrong gate. Validation runs offline, in any app, with no network.

The whole country, offline

A country's entire zone map compresses to the size of one photo thumbnail. Couriers resolve any code to zone level with zero connectivity, then sync the exact pin when signal returns.

National address systems stop at their borders. ADAS is the interoperability layer above them: national codes, postcodes, and Plus Codes resolve as aliases of one continental identifier — the same nine digits in Lusaka, Lagos, and Juba.

SHEET 04 · FOR BUILDERS

An address you can verify, not just deliver to.

Logistics networks route to it. Banks accept it as proof of address. Utilities bill to it. One integration covers every market you operate in — resolution is open, verification is the product.
