A comprehensive suite of easy to use, up to date, free, if not affordable, address postcode APIs.
We’re not just a leading UK postcode API lookup service, we’re so much more. We are approved licenced resellers for Ordnance Survey and Royal Mail and manage, maintain and link to a lot of other data including Companies House, Directors at Home, Police, Government, Ordnance Survey and Royal Mail’s Postcode Address File (PAF) & Multi Residency files.
We essentially provide information services delivered through one of several means: you taking out a licence and downloading comma separate files (CSV, Excel, etc), you uploading data to our servers for enhancement & cleaning, you sending us requests via our postcode API or you simply surfing our websites.
Well over 30 million verified UK address records!
No need to store and process these large cumbersome postcode data files yourself, no need for labour intensive processing of updates and changes or otherwise keeping on top of data decay, we take care of all of this inhouse, which must be a considerable time saving benefit for you?
Just some of the applications:
Requests to the API should be made over HTTPS so all traffic is encrypted.
The API responds to different methods depending on the endpoint.
| Method | Usage |
| GET | To retrieve information such as addresses or account data. |
| POST | To create a new resource. |
| PUT | To update the information in an existing resource. |
| DELETE | To permanently remove a resource from Addresses and Postcodes. |
All requests to endpoint V2 and V3 should be made to the following URL structure:
https://addressesandpostcodes.co.uk/api/version/resource/endpoint?key=your-api-key
Our legacy V1 API uses a slightly different API structure:
https://addressesandpostcodes.co.uk/api/pc2add/v1/resource/endpoint?key=your-api-key
The API always responds with HTTP status code of 200 code.
All responses are returned with a status parameter of 'success' or 'error'.
The basic request provides only plain address data from PAF sources. This is ideal for lightweight applications.

NHSERs (formerly NHS Commissioning Regions - NHS CR) are sub-divisions of the NHS commissioning board. There are four NHS ERs in England and they were renamed from NHS CRs in May 2017. The NHS CRs were formed on 1 April 2013, replacing pan SHAs, and are responsible for providing clinical and professional leadership at sub-national level. They are also responsible for the co-ordination of planning, operational management and emergency preparedness at sub-national level and undertaking direct commissioning functions and processes.

England and Wales - Parliamentary constituencies relate to those defined by the Parliamentary Constituencies (England) Order 2007, the Parliamentary Constituencies (England) (Amendment) Order 2008 and the Parliamentary Constituencies (Wales) (Amendment) Order 2008, and which came into effect at the May 2010 General Election. No further changes are envisaged until 2020. Scotland - The Scottish Parliament (Constituencies) Act 2004, passed by the UK Parliament in July 2004, came into effect upon the dissolution of the last UK Parliament and breaks the linkage between UK parliamentary constituencies and Scottish parliamentary constituencies. This Act has enabled the Westminster Government to reduce the number of Scottish constituencies in the UK parliament in line with recommendations made by the Boundary Commission for Scotland following its Fifth Periodical Review of Constituencies (December 2004). The Parliamentary Constituencies (Scotland) Order 2005 details the reduction of the number of constituencies for the UK Parliament from 72 to 59 Scottish seats. The changes bring the size of Scottish constituencies more into line with the size of English seats. English constituencies currently contain nearly 70,000 voters on average, compared to the Scottish average of 53,500. Northern Ireland - In Northern Ireland, the Commission's Fifth Periodical Report on Parliamentary Constituencies outlined changes to and the composition of constituencies in 2010. In practice, the new Parliamentary Constituencies are not very different to their predecessors. As before there are 18 constituencies, all retaining the same name. In the main, the boundary amendment process has involved the re-assigning of existing electoral wards from one constituency into a neighbouring constituency. The only exception concerns Derryaghy ward within Lisburn City local government district which previously resided entirely within Lagan Valley County constituency. It has now been split into two separate wards - Derryaghy (North) and Derryaghy (South), the former now included in Belfast West borough constituency, the latter remaining where it was.

"Statistical" wards were those electoral wards promulgated in Statutory Instruments by the end of a calendar year and implemented for statistical purposes on 1 April in the following year, irrespective of the year of statutory operation. The policy on statistical wards was agreed by ministers and was originally intended to minimise the impact on statistics of the frequent changes to the electoral ward boundaries. However, in 2006 a change to the policy on statistical wards was agreed by the then NSGG (the National Statistics Geography Group). The 1 April implementation date is retained but it now relates to those administrative and electoral areas that are statutorily operative on 31 December of the previous calendar year (i.e. statutory wards). As such, statistical wards no longer exist – the last set produced was 2005 statistical wards. The administrative and electoral areas in England and Wales for each postcode, used for statistical analysis.

In processing 2001 Census data for publication, 18 2003 statistical wards were identified as sub- threshold i.e. the count of population and households fell below the threshold for creating OAs and for the non-disclosive release of Census data. These 18 sub-threshold wards were combined with seven "receiving" wards to form acceptably sized OAs and permit publication of data. The sub- threshold wards are not separately identified in the ONSPD and postcodes in these statistical wards have been assigned to their receiving ward. The resulting set of wards is known as CAS wards. Sub-threshold wards (those below the threshold for creating OAs and for the non- disclosive release of Census data) are not separately identified in this field and postcodes in these "statistical wards" have been assigned to their "receiving ward". The resulting set of wards is known as "CAS Wards". A pseudo code is included for Channel Island and Isle of Man. The field will otherwise be blank for postcodes with no grid reference.

National parks are designed to conserve the natural beauty and cultural heritage of areas of outstanding landscape value, and to promote public understanding and enjoyment of these areas. There are currently 13 national parks in England and Wales. Of these, 10 were designated in the 1950s following the National Parks and Access to the Countryside Act 1949, The Broads (Norfolk/Suffolk) has had a similar status since 1989 (the Broads has its own special authority, the Broads Authority, which is similar to the National Park Authorities but with extra powers in relation to navigation) and The New Forest was given national park status in 2005. The South Downs is the latest national park, becoming fully operational on 1 April 2011. In Scotland the National Parks (Scotland) Act was passed in July 2000. The first Scottish national park, Loch Lomond and the Trossachs, was established in July 2002, and the Cairngorms National Park was established in March 2003. Their boundaries are not constrained by any other geography. The national parks cover parts of England, Wales and Scotland.

Our data is very up-to-date. Our address data is regularly updated from various sources, including Royal Mail's Postcode Address File database, and is enhanced with real-time corrections from address owners/occupiers submitted through our site (no other API service offers this additional feature).
Just register a free account and purchase an API credits pack, upon which we will assign you a dedicated API key in order to use our API lookup service.
A lookup is a search of a full UK postcode against our entire address database.
Lookup credits are one flat low rate of 2.5p each. It's that simple.
All credits in a pack expire one calendar year after purchase. Upon this expiry, they are considered lost and non-refundable.
If your lookup fails to get a list of addresses for any reason (e.g. an invalid UK postcode was searched), no credits will be deducted.
Not yet but we are working to hard to complete it. Over time we will complete the documentation and expose our hundreds of endpoints.
Currently there is not rate limit to paying customers. We reserve the right to change this at any time.
All our data is stored in London using an industry leading cloud provider.
The API has been designed and built over many years with best practices at the time being applied. We are working very hard to standardise the end-points. V3 of our API is our LTS release.
Please let us know if any of our API endpoints are not returning useful error messages and we will work with you to fix your API query.
Yes. While our service is designed to be self-service and fully automated, we offer support for any technical enquiry. Simply get in touch with us and we will get back to you within one business day (in most cases, within a couple of hours).
We guarantee availability of at least 99.9% from our high-performance multi-core cloud servers.
