Where "geographic area" can mean "moved a block, no longer technically in the same municipal area", yes. I'll give you one guess why I know this. Yes, most cases port just fine. I've ported multiple times successfully too. But no, your number is not "yours". It's the telecom's, and they decide if you can keep it or not... and they have a history of choosing so poorly that they are now legally required to make a better choice most of the time. It really does not imply good things about trust in their future behavior.
