Royal Mail are Strategetic Partners with Allies Computing

The authoritative source for UK address data

Royal Mail delivers letters and parcels to around 30 million addresses across the UK. With a rich and varied heritage, Royal Mail has helped the world to communicate for over 500 years.

Allies has been an authorised licensor of Royal Mail data since the early 1990s when the postal operator first began to licence their Postcode Address File (PAF) database for commercial use.

Alongside PAF, we offer the Multiple Residence, Alias and Not Yet Built datasets. These datasets enrich PAF with details of multiple occupancy properties and properties under construction. We also provide British Forces Post Office postcodes.
