What do you like best about Postcoder?

I've been using Postcoder for over 5 years now, and it just works without any issues. It's simple to configure, and my sales and delivery team use it daily without even realizing they're using it. I really appreciate its ability to link with our ERP system to help locate customer delivery addresses accurately. The accuracy is crucial for providing great customer and delivery service. The initial setup was very easy, taking only about 20 minutes, including setting up the account. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Just keep an eye on the credits - if you don't have auto topup enabled it can bring everything to a halt Review collected by and hosted on G2.com.

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

Response from Rachel Potter of Postcoder

Thanks for your review, Theodore! We're delighted that you were impressed by our support team and that the service is as speedy, accurate and worry-free for you as we have designed it to be.

For the benefit of other readers: Postcoder supports two-character ISO country codes and accepts both UK and GB (the official code) for UK address lookups.

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

Cant 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.

Response from Rachel Potter of Postcoder

Hi Tim, thank you for your loyal support and for sharing such positive feedback — it’s great to hear Postcoder is making a real difference for both your customers and your team. We appreciate your suggestion about a monthly fee option for smaller use customers and I will pass this onto the team for consideration.

"Seamless Address Verification, Exceptional Support"
What do you like best about Postcoder?

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. I also greatly value the high quality of address lookups, which ensures top-tier results from credit checks and eliminates manual searches for our customers. 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.
