OVERVIEW
The Royal Mail Alias File is a specialist dataset that enhances UK address data by resolving common issues caused by alias addresses—alternative names, non-standard formats, or locally known place names that don’t match Royal Mail’s official delivery addresses.
Alias data is not included in the standard Postcode Address file (PAF), however is an additional dataset that can be used to enhance existing address information. It includes 3 million records, so having access with aliases alongside PAF will help identify accurate address more quickly.
There are four types of alias records: Locality, Thoroughfare, County and Delivery point aliases.
- Locality records include local names and Postally Not Required (PNR) details.
- Thoroughfare records include alternative, unofficial and combination names used locally for streets and thoroughfares
- Delivery Point Alias records include additional information such as trading names and building names.
- County Alias records include historic county names, administrative and postal county information.
