"Good Experience with PostCoder"

4/5

What do you like best about Postcoder?

Postcoder is very basic and easy to use, easy to implement over other postcode searches we've used.

Any of our developers are able to pick this up and use it within our code base.

Email alerts when over credit use. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

Some of the reporting is hard to read or understand. Especially the credit usage. I receive emails saying our credit usage is high but unable to see where and why easily in their reports dashboard. Review collected by and hosted on G2.com.

"Excellent product. When we found a bug, they fixed it straight away."

4/5

What do you like best about Postcoder?

The Postcoder API allows us to perform address autocomplete and lookup for our users in any country with the same code. This made it quick to set up. In addition, it gives us the address unique identifiers that we need to send to our printers for mailsorting in the United Kingdom. When we found a bug in the address autocomplete endpoint for one country, the development team fixed it right away. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

It would be helpful for the documentation page to have even more examples for different countries. Review collected by and hosted on G2.com.

"Seamless Integration and Great Reliability"

5/5

What do you like best about Postcoder?

Postcoder is a great tool we've integrated directly into our applications for checking addresses, emails, mobile numbers, and bank details. It's really reliable and easy to use, fitting perfectly into our systems without any hassle. Their customer support is top-notch, always ready to help if we need it, and the price is pretty good too. All in all, Postcoder makes our work a lot smoother and we're really happy with it. Review collected by and hosted on G2.com.

What do you dislike about Postcoder?

I'd say that it's worth noting that accessing additional data for addresses comes at a higher cost. Moreover, the bank verification feature, although useful, is quite basic and may not meet the needs of those seeking more in-depth financial data verification. Review collected by and hosted on G2.com.
