I appreciate Postcoder’s robust and detailed API documentation, which made setup incredibly swift and seamless. The thorough SDKs were immensely valuable in this process.

This leads to high customer satisfaction and conversion rates, sometimes exceeding 80% in lending journeys. My overall experience with Postcoder has been excellent from the start, so much so that I would unequivocally purchase it again and recommend it highly with a perfect score of ten out of ten.

"Postcoder does so much more"

3.5/5

What do you like best about Postcoder?

We've been using Postcoder.com for many years and have had a fantastic experience. Originally we just used it for address lookup, the platform has evolved significantly, offering much more than just postcode validation.

The additional features help create a more detailed profile of customers and verify key details, improving data accuracy and customer insights. The service is fast, efficient, and integrates seamlessly into our systems. Their continued innovation and excellent support make them a valuable partner. If you're looking for address verification and customer data enrichment solution, Postcoder.com is a top choice. Highly recommended! Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

It would be great if the pricing on other items was for rounded credit not like 2.4 credits for a mobile look up. other than that its great. Review collected by and hosted on G2.com.

Response from Rachel Potter of Postcoder

edit

Hi, thanks so much for your positive feedback; we're really pleased you're taking advantage of some of our additional features and that you have found our support to be as helpful as we intend it to be. We appreciate the comment regarding the credit pricing; we did consider rounding certain credits to the nearest whole or half credit, but by keeping them rounded to the nearest decimal place it allows us to keep our prices as cost-effective for our customers as possible. We will bear it in mind for future price changes though!
