Mobile app

08 December 2021

We are now able to make addressing available as an Android app, named AddressUK.

Address UK
Unlike all other similar products, AddressUK does not perform lookups over the Internet.  Although this is the cheaper option, it suffers from serious communication delays and possible loss of signal.
The entire Royal Mail database of 2m road-level addresses is stored within the user's phone, advanced compression techniques making this eminently practicable, and giving instant response.

An evaluation copy can be downloaded at no cost through PlayStore: simply search for 'AddressUK'.
