[Maritime Q-Scout]

This may be better suited for the tech forum, I'm not sure as it wasn't specifically a tech question.

I just moved back to Nova Scotia, and changed my cell phone from a New Brunswick number back to a good ole 902 exchange.

Now I'm thinking, who do I have to let know that my cell phone number has changed

I mean friends, family obviously, but what about businesses, websites? I'm not sure who I gave out the old number to and who I didn't. Does anyone have a list they usually inform with regard to these things?
