Case Study: Bluenumber achieves precise identity validation and location verification with what3words

Validating identities with what3words and Bluenumber

what3words and Bluenumber have teamed up to tackle a common problem: many people and small-scale actors in global supply chains are effectively “invisible,” making it hard to verify identities, locations and progress toward the UN Sustainable Development Goals. Bluenumber’s BlueView is a free, open public registry that lets people announce and own their data, and the challenge was to link those digital identities to precise, verifiable locations.

By integrating what3words’ 3‑word addresses into BlueView, users can associate a Bluenumber with a precise 3 m x 3 m location, self‑verify it and invite public confirmation (for example: ///dynamic.assessors.apart, Pasul Tihuta, Romania). The result is improved identification and accountability for farmers, makers and resellers, better benchmarking of performance, and richer, location‑accurate data that helps governments, businesses and NGOs measure SDG progress and design more effective interventions.
