Pin number

If you did not pre select the 4 digit pin at time of new service (which prob not), then it would be the last 4 digits of your cell phone number.....Yep, that should do the trick.........

For my phone transfers, i had several by the way, it ended up being the last 4 digits of my social security number. Otherwise call the provider and they must give it to you. They can't keep your pin from you or tell you if its your soc sec number.
