Can you use a use your old phone number with new verizon prepaid account

You can, but if you're shopping for new prepaid or post pay service, I would recommend checking more than just the 4 main names everyone knows. There are a lot of quality services available much cheaper. Not all numbers are available to switch, but most are. You should be able to check your number on their website.

Yes you can. I was alltel and I switched to Verizon and I have had this number for 22 years
