City from Post code

Hi.
I created some feature in my Invoice Plane v1 (i’m a developper too), and i would like to know if they have already been developed in IP2 or do i need to redevelop them :

One of them is an autocompletion list that shoes cities from an entered post code when i create or modify a customer.
It is very much used in my country (France) because there are multiple cities for one post code (it is much easier to enter a 5 digits post code instead of a long city’s name) and i’m sure that the city’s name is correctly inserted.

For the moment, i have created a simple table with cities names and post codes. But i’m sure that there are some web services that gives these informations.

Thanks for reading
