What are my chances of salvaging my old landline number?

I figured some teleco geniuses out here, so I figured I might give it a shot.

The house I grew up in is looking to get rid of it's landline, and thus it's phone number. This phone number is one of the small number I actually have memorized-making it super useful, because I am unlikely to memorize any additional numbers in my lifetime, and certainly no numbers will ever have the same nostalgic ring to them.

They're a different phone carrier, and a different state. The current owner would be happy to hand the number over. Is this type of transfer in the realm of possibility?
