Porting number from Bell MTS

[Siliron]

I'm going to sign up and transfer shortly from a Bell MTS account. To port my number should I use the account number that shows on the top of my BellMTS bill or should I use Mobility Bill Number that shows up on the mybell site? Or does it not matter?

@Siliron  Use the account number on the bill. And ignore the IMEI
