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.
