Zip Code

Hi

In the Leads section I have hidden the Zip Code entry and added a Post Code Pick List in which I have entered the local post codes for Brisbane, Australia.

My questions are:

Is it possible instead to convert the Zip Code to a Pick List?

When I convert a lead to a potential will the new Postcode field show?

I would also like to do the same for the City field. Is that at all possible?

Thank you

Jean
