Add Postal ZIP Code; Need Longitude & Latitude

[IamTDR]

Hi
In my data model, I have a field for Postal ZIP Code. 

What is the best method to add two additional fields for longitude/latitude?

Hi IamTDR,

You might want to find a database having the link between ZIP Code and Lat/Lon

Depending of your country there's open data on some website

Or you could take a look here :
