Autocomplete addresses
using one single API
With the Postcode.eu Address Autocomplete API you are assured of accurate addresses in your webshop and company. All your customers and/or employees can fill in addresses faster and error-free using the autocomplete function. This enables your system to recognise and correct incorrect addresses before they actually are entered in your system.
You can use the address auto complete in your webshop, site or office system, but the possibilities go even further. You can also validate existing address files and do this periodically. The API uses smart technology that detects and corrects spelling errors.
Save time and money
At the end of the day, you really do save a lot of money. Addresses get entered much faster and there is no need to maintain seperate address systems anymore.
The costs of undelivered parcels will also go down because you only work with error-free addresses that actually exist.
“One wrong address can lead to customer loss or missed sales. If you have a hundred wrong addresses, you can calculate your loss.”
Address data of multiple countries
The API offers addresses from Austria, Belgium, Denmark, Finland, France, Germany, Luxembourg, Norway, Spain, Sweden, Switzerland, the Netherlands and the United Kingdom. Your international customers can fill in their addresses more quickly and without faults using the autocomplete. All your customer has to do is start typing and choose the right address from the suggestions.
New countries are constantly added to the Address Autocomplete API. As soon as a new country is added, you can request its addresses immediately. No hassle with extra subscriptions, acces to all available countries is covered by one subscription.
Reliable
It is important to work with reliable data, which is why we only work with official sources such as postal companies and governments. As a result, you are assured of high quality and accurate data: completely up-to-date!
It's nice to have reliable data, but without reliable servers it's of no use. That's why we do everything we can to make sure our servers are always up. And with a response time of 0.02 seconds, they are also fast!
Reliability is very important, as is privacy. With us there are no shadowy free models that resell your data or trackers that follow what you or your customers do. Your data is safe with us.
