hate to say it but odds are that number has been recycled after 2 years..you can try calling it to see if someone answers or what it says..

The number is lost  , it goes back into the number pool after 90 days after the account is canceled.

numbers after 3 months of closure of accounts goes back into a pool of numbers and back into the carrier who owns the actual number.  For example my number is originally from Verizon.  If I close my T-Mobile account my number will go back to Verizon after 3 months.  

 i have 2 lines I transferred one to google voice. They cancel the other one by default. 

I need my number how can I reactivate it ?
