Frequently asked questions
Which UK address API is cheapest?
Per-lookup cost depends on volume. AutoPostcode publishes rates from about 3.8p per lookup on entry plans down to under 2p on higher-volume annual plans, and will beat any like-for-like written quote from another UK provider.
Do all UK address APIs use the same data?
Most reputable UK providers work from the same official Royal Mail address file, so the underlying addresses are comparable. The differences are price, API design, autocomplete quality, plugins, and support.
How hard is it to switch provider?
Usually a single endpoint change. AutoPostcode includes free migration and integration support, plus a WordPress/WooCommerce plugin if you don't want to write code at all.
