POSTCODES.IO

POSTCODES.IO is a UK geolocation API that automatically determines the postal code of any location on the map. With this e-commerce integration, you can select customer postcodes based on their address and location, automatically fill in the appropriate field in the order, and check the correctness of the manual entry.

4 reasons to connect POSTCODES.IO to your website
01
01
Easier for the customer

Incorrect postal code is the main problem of delays and delivery errors. With Postcodes enabled, your UK customers will no longer need to remember or search for their 7-letter and 7-digit code. The site will automatically fill in the field using geolocation data based on the location or the entered address. With the mass reverse geocoding API, you can find addresses by points on the map and even place icons with indexes on it to make the search even more convenient. In Ukraine, Ukrposhta started providing such an API only in 2019, but in order to use its functionality, you need to conclude an agreement with the carrier as a legal entity. POSTCODES.IO is free software that can be used in any project without restrictions.

API methods for every situation

With POSTCODES.IO, you will be reliably protected from accidental customer errors that can lead to loss of cargo and damage to your reputation. The API can find a postal code by address and geolocation (longitude and latitude of the device from which the order is being placed). If the customer entered the zip code manually, the system will check its correctness, including by checking with the nearest ones. And if the field is only partially filled in, it will offer the correct options. You don't have to ask customers to enter the zip code at all, but automatically select it in the order management system. This can also be convenient for grouping shipments to different regions and optimizing logistics. To test the capabilities of Postcodes during development, you can use a random index generator.

Free license

POSTCODES.IO is a free API developed by the GitHub community. The free MIT license allows developers to use the code for any project by simply posting the text of the agreement on the website, along with the documentation of other used integrations. The official Postcode website contains the most popular ready-made solution libraries for Java, PHP, Node.js, Python, C#, and others. They can be used by all interested developers, just as they can create their own unique solution based on open source.

Always relevant

POSTCODES.IO is regularly updated from open government sources. You and your customers won't need to worry about changes to the United Kingdom map. On average, the general data update is carried out every two to three months.

Conclusion

POSTCODES.IO is a very useful API for anyone who ships goods within the UK. It is able to determine zip codes by address and geolocation, correct errors and automatically fill in the appropriate line, and can also be used for other purposes, such as map customization, as free software. Integration of Postcodes will protect your business from accidental mistakes made by customers and employees responsible for organizing delivery, as well as improve the UX of the site and user experience.
