Frequently Asked Questions

Billing & purchasing

Our plans contain a specific number of lookups and run for either a month or a year. A plan will last until its lookups are used or it reaches the end of its term.

If you have selected a subscription, at the end of your active plan your account will be renewed with the same plan. You can always visit your account on the Admin Portal to update which subscription you prefer.

We offer our annual plans without a subscription. Please note that accounts without any active plans will be suspended automatically.

Yes. Each Global Address Auto-Complete and UK Postcode search uses one lookup.

For high usage in the UK, we offer the option of annual licences. This is part of the Royal Mail PAF licence. Please speak to us for details.

Yes. We send emails when your subscription is due for renewal or in danger of expiry.

  • Annual Subscriptions: you will be notified of an upcoming renewal when your plan falls below 20% and your plan will renew when it reaches 10%.
  • Monthly Subscriptions: you will be notified that your plan has renewed when it reaches 10%.
  • One-off purchases: you will be notified when your plan falls below 20% and then again when it falls below 10%.

Please ensure that we do have a valid email address and phone number for you. This is important so that we can contact you before suspending an account that has expired.

We are happy to issue VAT free invoices for eligible customers.

Please contact us and provide proof that you are entitled to purchase free of VAT in the UK. We can set your account to be VAT free and any future invoices will not include VAT.

Data quality and reliability

We source our data from a number of selected providers, including the Royal Mail, HERE and Ordnance Survey.

This means that our address data is the most current and up to date available. For most countries, our data is updated monthly or quarterly. In the UK it is updated on a daily basis.

The UK PAF® data is updated on a daily basis.

The Royal Mail PAF® changes constantly – new addresses are added and properties are built or modified, addresses are removed and errors corrected. We make sure that our data is always reflecting the current state of the official PAF® data base.

We aim for 100% uptime including updates and maintenance. Since 2008 when our postcode lookup web service went live we have had no down time at all. Our web service is structured in a way that makes it robust to failures :
  • It is delivered from two completely autonomous data centres. Each location can handle 100% of the load and does not depend on any other part of our system.
  • We run on a distributed anycast DNS infrastructure, providing active fail over between our locations. This is managed for us by DYN Inc.
  • All updates and maintenance are performed without taking the system off line.


Some of our data suppliers specify that all lookups must expire within 12 months.

Any lookups purchased from Fetchify will last for a maximum of one year. If multiple plans are purchased at the same time, the expiry periods will run consecutively and each pack will have a full shelf life.

Our data is supplied by a number of suppliers, including the Royal Mail PAF® and HERE. Use of some of the data sets require agreement with end user terms.

When you sign up for an account with us, you will need to read and agree to our terms of trade as well as the end user terms for specific data sets/suppliers.



Yes, our API does return province and UK county names where available.

In UK, since the postcodes were fully implemented, the Royal Mail have stopped supporting counties and they are no longer required as part of a postal address. There is no central authority in the UK to define a single set of counties and their boundaries. There are at least three different sets of county names in circulation :

  • Former Postal – as used by Royal Mail in the past for mail delivery purposes
  • Traditional – the “real” county names going back in history
  • Administrative – this includes unitary authorities

More information about the confusion around county names in the UK can be found on Wikipedia.

Our advice is to leave county names out of UK addresses completely. The county name is not needed as part of an address in the UK and Royal Mail sorting machines would ignore it anyway. However, our system does provide a choice of traditional and former postal county names for customers who do require this data.

We don’t provide a separate sandbox environment, but free trial accounts are available with 100 free lookups for testing. 

Signing up for a trial account with us gives full access to the data for a limited number of requests. There is no commitment and no credit card is required, you only pay if you decide to use our service on a live system.

Once your trial period is finished and you convert to a live, paid for account, we also have some free postcodes you can test with:

  • UK Postcode Lookup API – the free test postcodes are AA1 1AA, AA1 1AB, AA1 1AD and AA1 1AE. They represent fictitious data.
  • Auto-Complete API – you can test for free with our own real postcode SL6 1QZ. The data is real and has a mix of residential and commercial addresses.

In most cases our API servers will respond in well under 10ms.

The exact speed of response will depend on the internet connection speed. Once all the DNS and connection overheads are included, total response times your application is likely to see should always be well below 200ms. We monitor our API performance from a variety of locations around the world.

The risk is small and we do provide a way to make it secure.

There are two ways to reduce the risk of your token being abused :

  • Our system allows a token to be locked to a specific domain(s). Usage on any other domains will be denied.
  • Use a data relay script on your own server. This will hide your token on your server and you can implement additional security there.

This answer assumes you are using the client side JavaScript integration. If you are using a server side integration, it will not be applicable as your token is then already hidden in your server-side code.

Please get in touch if you would like more information on this topic.

The access token is like a user name and password combined. It gives access to our APIs.

When you sign up for a trial account, a trial access token is created for you automatically and sent to your email address. While your account is in trial mode, your token should only be used for testing and evaluation.

When you purchase from us for the first time, the same access token is activated and can then be used for lookups on a live system.

Your developers will need the access token in order to add (integrate) our address search to your application or website.
