Is your database up-to-date?
Yes. Our Address Database is updated everyday against Royal Mail's Postcode Address File so you can be confident you won't miss the latest address changes.
How do I use Ideal Postcodes?
Just sign up and create an API Key for free. You can load keys with prepaid lookups if you want to use our paid API. Otherwise you can use the token for our free API.
What is a lookup?
A lookup is any database lookup on Royal Mail's Postcode Address File. Each lookup incurs a license fee to Royal Mail. For example, one postcode search on /postcodes/:postcode equates to one lookup.
What are the available payment methods?
We accept Visa and Mastercard. Please get in contact with us if you would like to use an alternative method.
What is Postcodes.io?
Postcodes.io is our open-source postcode API service that uses Open Data from the Office of National Statistics. This project would be ideal for you if you are primarily looking to geocode or reverse geocode postcodes.
Are there any other fees?
There are no contracts, overages, fees, or licence charges at Ideal Postcodes. All you pay for is the number of lookups you wish to make.
Is help available?
Yes. We are available for live chat on our support page or via this link for debugging and general queries. We are also available for support queries via email.
Do you use the Multiple Residence Dataset?
Yes. If you wish to query this data, you may generate a separate key to combine this dataset with PAF. The additional cost per lookup is 0.5p.
