      post_town paf_post_townrequired

      Possible values: <= 30 characters

      **Filter by Town or City" A Post Town is mandatory for delivery of mail to a Delivery Point. This is not necessarily the nearest town geographically, but a routing instruction to the Royal Mail delivery office sorting mail for that Delivery Point. A Post Town will always be present in every address, and for some Localities the Post Town will be the only locality element present.

      postcode Postcoderequired

      Possible values: >= 6 characters and <= 8 characters

      Correctly formatted postcode. Capitalised and spaced.

      county Countyrequired

      Since postal, administrative or traditional counties may not apply to some addresses, the county field is designed to return whatever county data is available. Normally, the postal county is returned. If this is not present, the county field will fall back to the administrative county. If the administrative county is also not present, the county field will fall back to the traditional county. May be empty in cases where no administrative, postal or traditional county present.

      county_code County Coderequired

      Short code representing the county or province. May be empty ("")

      uprn Unique Property Reference Numberrequired

      UPRN stands for Unique Property Reference Number and is maintained by the Ordnance Survey (OS). Local governments in the UK have allocated a unique number for each land or property.

      Up to 12 digits in length.

      Multiple Residence premises currently share the same UPRN as the parent premise.

      May not be available for a small number of Great Britain addresses due to longer update cycles for Ordnance Survey's AddressBase datasets. Returns empty string "" in these instances.

      Although UPRN takes an integer format, we encode and transmit this data as strings. As a 12 digit number, the UPRN can exceed the maximum safe integer Number.MAX_SAFE_INTEGER in most browsers causing this datapoint to be corrupted.

      Take special care when storing UPRN. As a 12 digit identifier, you will need 64 bits to encode every possible UPRN value. This means applications like Excel will corrupt cells containing UPRN values.

      udprn int32required

      UDPRN stands for ‘Unique Delivery Point Reference Number’. Royal Mail assigns a unique UDPRN code for each premise on PAF. Simple, unique reference number for each Delivery Point. Unlikely to be reused when an address expires.

      Up to 8-digit numeric code.

      A new UDPRN is automatically assigned to each new Delivery Point added to PAF.

      umprn object required

      A small minority of individual premises (as identified by a UDPRN) may have multiple occupants behind the same letterbox. These are known as Multiple Residence occupants and can be queried via the Multiple Residence dataset. Simple, unique reference number for each Multiple Residence occupant.

      Note: this will be an empty string "" when not used.

      postcode_outward Postcode Outwardrequired

      Possible values: >= 2 characters and <= 4 characters

      The first part of a postcode is known as the outward code. e.g. The outward code of ID1 1QD is ID1. Enables mail to be sorted to the correct local area for delivery. This part of the code contains the area and the district to which the mail is to be delivered, e.g. ‘PO1’, ‘SW1A’ or ‘B23’.

      postcode_inward Postcode Inwardrequired

      Possible values: >= 3 characters and <= 3 characters

      The second part of a postcode is known as the inward code. e.g. The inward code of ID1 1QD is 1QD.

      dependant_locality Dependant Localityrequired

      Possible values: <= 35 characters

      When the same thoroughfare name reoccurs in a Post town, it may not be possible to make it dependant on a dependant thoroughfare. In this case the thoroughfare is dependant on a locality. For example if we want to find 1 Back Lane in Huddersfield we see that there are three.

      Possible values: <= 80 characters

      Also known as the street or road name. In general each Thoroughfare Name will have a separate Postcode. Longer Thoroughfares with high number ranges often have multiple Postcodes covering the entire length of the road, with breaks at suitable points e.g. junctions or natural breaks in the road.

      dependant_thoroughfare Dependant Thoroughfarerequired

      Possible values: <= 80 characters

      postcode_type Postcode Typerequired

      Possible values: [S, L, ``]

      This indicates the type of user. It can only take the values 'S' or 'L' indicating small or large respectively. Large User Postcodes. These are assigned to one single address either due to the large volume of mail received at that address, or because a PO Box or Selectapost service has been set up. Small User Postcodes. These identify a group of Delivery Points.

      On average there are 19 Delivery Points per Postcode. However this can vary between 1 and, in some cases, 100. There will never be more than 100 Delivery Points on a Postcode.

      su_organisation_indicator Small User Organisation Indicatorrequired

      Small User Organisation Indicator can have the values 'Y' or space. A value of 'Y' indicates that a Small User Organisation is present at this address.

      delivery_point_suffix Delivery Point Suffixrequired

      A unique Royal Mail 2-character code (the first numeric & the second alphabetical), which, when added to the Postcode, enables each live Delivery Point to be uniquely identified. Once the Delivery Point is deleted from PAF the DPS may be reused (although they aren’t reused until all remaining Delivery Points in the range have been allocated). The DPS for a Large User is always '1A' as each Large User has its own Postcode.

      premise Premiserequired

      Possible values: <= 84 characters

      A pre-computed string which sensibly combines building_number, building_name and sub_building_name. building_number, building_name and sub_building_name represent raw data from Royal Mail's and can be difficult to parse if you are unaware of how the Postcode Address File premise fields work together. For this reason, we also provide a pre-computed premise field which intelligently gathers these points into a single, simple premise string. This field is ideal if you want to pull premise information and thoroughfare information separately instead of using our address lines data.

      The current administrative county to which the postcode has been assigned.
