A what3words Case Study
Allies is an international address‑verification platform used by UK organisations including IKEA, the NHS and the Post Office, maintaining daily updates across 240+ countries. Because global addresses are frequently mistyped, incomplete or imprecise, e‑commerce and delivery firms suffer lost revenue and missed deliveries; Allies’ PostCoder Web API was built to correct, standardise and auto‑fill addresses at scale.
By integrating what3words into PostCoder Web, Allies lets businesses convert addresses to 3‑word locations and look up addresses from a 3‑word code, and accept 3‑word input at checkout. The integration delivers precise 3m×3m delivery points for drivers, reducing time spent locating properties, improving delivery efficiency and customer satisfaction—particularly for new builds and poorly addressed rural areas.
