Porting Number Question

[b17777]

In MN they shuffled prefixes around and I no longer live in the area code of my cell phone.I need to keep my number as I'm self employed and I need the phone to keep ringing, so having to get a new number is a deal breaker for me. Do I need to give an address in the area code of my current phone? Anyone have any experience with this ?

I'm not sure if there are exceptions, but when I ported my number this weekend (Verizon -> AT&T), the rep told me that my billing address had to match the zip code of my number, otherwise the port would fail
