The API feed contains records and related data we have for addresses and businesses under any full and valid UK postcode.

Our records come from the following sources:

  • Royal Mail PAF (Postcode Address File®)
    Royal Mail's PAF is the most up-to-date and accurate database of addresses in the UK. Our local PAF database is updated every three months, and is enhanced with approved user-submitted amendments and updates, particularly enhancing accuracy of the business/organisation information available within PAF.
  • Royal Mail PAF Multiple Residence
    While PAF maintains an accurate record of individual delivery points, the Royal Mail Multiple Residence data enhances this by allowing identification of properties where two or more dwellings share a single front door. Our local Multiple Residence database is updated every three months, and is enhanced with approved user-submitted amendments and updates, particularly enhancing accuracy of business/organisation information.
  • Companies House
    We maintain a database of all active Companies House businesses with a UK-registered address. This is public domain data, and is locally updated every three months.

Additionally, we also include other useful data with every address record, including address counts, the country/region/district/ward, coordinates and constituency/MP information. Note that the maximum delineation of this extra information is at postcode unit-level; so all addresses which share the same postcode unit will share the exact same additional information.

How up-to-date is our address data?

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).

How do I use this service?

Just register a free acount and purchase an API credits pack, upon which we will assign you a dedicated API key in order to use our API lookup service.

What is an API lookup?

A lookup is a search of a full UK postcode against our entire address database.

How much are the credits?

Lookup credits are one flat low rate of 1.5p each. It's that simple.

Do the lookup credits expire?

All credits in a pack expire one calendar year after purchase. Upon this expiry, they are considered lost and non-refundable.

Do we deduct a credit if the lookup doesn't produce any data?

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.

What payment methods are available?

All payments are securely processed through PayPal, which means you can pay with nearly any UK bank account or credit/debit card.

Are there any other fees?

There are no contracts, overages, fees or any other additional charges. All you pay for is the number of lookups you wish to make.

Is there any technical support?

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).

What is your service uptime?

We guarantee availability of at least 99.9% from our high-performance multi-core dedicated server.
