"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.

Since we used their API's it is now even easier for anyone to be able to start using their service. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Response from Garrie Clayton-Flatt of Postcoder

Hi Anthony, we really appreciate your feedback and are glad to hear that you found Postcoder a simple API to integrate into your CRM, and that by using it you benefit from not needing to update or host data yourselves.

"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.

We love the developer-friendly API; it makes integration into websites and applications very simple. This, combined with its highly accurate and reliable address data, makes it a powerful tool for our business as we want to improve data quality and streamline our checkout or sign-up processes. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

It's a bit challenging to manage team members within the admin dashboard. And the credit-based pricing model can be a bit complicated. Review collected by and hosted on G2.com.

Response from Rachel Potter of Postcoder

Thank you for your great feedback—we’re really pleased to hear Postcoder is helping to improve your data quality and simplify integration. We appreciate your comments on managing users on the dashboard and this is something out development team are currently working to improve. Regarding our pricing, our credit-based model is designed to be flexible and cost-effective by letting you use just one credit pack across all our services, but we do understand that it may not be clear for all users, so please see https://postcoder.com/pricing for a breakdown of costs and how many credits each request will use.

"Simple to use API, Excellent Support"
What do you like best about Postcoder?

I found Postcoder easy to setup and we utilise the API to retrieve and confirm Eircodes (Irish post codes). The graphical user interface (GUI), is well designed and has all the key features needed. The customer support provided by Postcoder has also been excellent, offering prompt and effective assistance whenever required. Review collected by and hosted on G2.com.

"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.

"Postcoder does so much more"
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

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!
