# UK Alias Addresses

The Alias address format is identical to the [Postcode Address File](/docs/data/paf.md) format.

Alias address results are labeled with `pafa`.

Alias addresses are alternate representations of a UK address found on the main Address File. Typically these are:

* House name additions on numbered properties (e.g. `Rose Cottage` at `2 High Street`)
* Business name additions for companies operating from home (`Jones Plumbing` at `2 The Avenue`)

Aliases addresses are extracted from Royal Mail's Alias file to supplment the Postcode Address File. They are not required for delivery purposes.
