Reply To: Customizing map field info/need phone ext to show

@ Shea

Well, you could add the extension after the phone number like so:

800-355-1990 Ext 1204

That is how I see phone numbers listed in most cases.

I bit more complex… you could add a custom phone number type, Extension and add it as a second number. See this tutorial on how to add custom phone number types.

Hope that helps!
