"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?

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.

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

It helps us by making checkout easier for our customers therefore increasing the likelyhood 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 work load for our customer service team.

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.

"Seamless Address Verification, Exceptional Support"

5/5

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 -Best in class address lookup tooling"

5/5

What do you like best about Postcoder?

The ease of use and their documentation is superb. Allowing me to hook up to the service very easily. They also have a wide offering of services that I haven't taken full advantage of yet, but nice to see they have a good ecosystem. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Not clear how to add other members of my team there, it'd be good to allow other members of my organisation to manage it. Could just be something I've missed though Review collected by and hosted on G2.com.

"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!
