"Postcoder is a great address search API — well-built, cost-efficient, scalable, with great support."

5/5

What do you like best about Postcoder?

Postcoder offers an excellent developer experience — the documentation, examples, and support are all well delivered. The API security is thoughtfully designed, with fine-grained controls for rate limiting, domain restrictions, emailed alerts and more. Usage metrics and detailed logging are also very helpful — overall, it’s a highly developer-friendly platform.

For our user experience, the address searches are near-instant, creating a light-touch, frictionless journey for our customers. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Very little to dislike about Postcoder. One minor detail was the use of non-standard country codes for defining address searches — but the service desk was very helpful, quickly providing the correct codes, and the issue was resolved within 20–40 minutes. Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

Postcoder supports both our internal and external user experience by enabling fast and accurate address entry through its address search and email verification features. This speeds up data input and ensures consistent, verified data — which is essential for reliable reporting and operational accuracy. Review collected by and hosted on G2.com.

"Been using Postcoder for years and it works great for us and our customers!"

4.5/5

What do you like best about Postcoder?

Postcoder just reliably works in the background, giving our customers easy and reliable data so they can check out quickly and we get accurate data then for our delivery partners. It was easy to set up and never seems to be out of action or need amendments from us leaving us free to get on with what we need to do in other areas of the business! Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Can't think of any to be honest! Maybe a small monthly fee option would be better than periodic top ups? Review collected by and hosted on G2.com.

What problems is Postcoder solving and how is that benefiting you?

It helps us by making checkout easier for our customers therefore increasing the likelihood of spending with us. It also helps us get consistent address data for our delivery partners meaning they are less likely to have address issues meaning missed deliveries and upset customers and increased workload for our customer service team.
