About
This API lets you validate postcodes within the United Kingdom.
Postcodes are used by delivery services to do delivery route planning and to provide recommendations based on your users' area among other scenarios. In such cases, validating UK postcodes when collecting them from users ensures that you can alert them in case of mistakes and collect only valid addresses. This can help reduce the cost of returned or undeliverable mail. By ensuring that addresses are accurate and complete, organizations can reduce the need for manual processing and re-delivery of orders.
Try out the API in the API playground and see how this free online postcode validator API can help you validate postcodes easily, save time, and reduce validation errors through a simple API call.
