Here is how to get your Thumb Cellular account number and transfer PIN, and what to do with them when you move your number to another carrier.
Account Number
Thumb Cellular only requires your account number and PIN to port out. They do not offer any online accounts, so you will have to contact Thumb Cellular customer service number or visit a local care center in Michigan to get your account number and PIN.
Transfer PIN
Ask for the transfer PIN in the same call. Thumb Cellular issues the account number and the PIN together.

Check coverage before you port
Thumb Cellular owns and operates its own towers inside its home service area, so at home you are on Thumb Cellular’s own network, not a national one. Outside that area your phone roams onto Verizon, which is the coverage that applies when you travel. Check it on Verizon’s own coverage map before you start the transfer.
Your right to keep the number is federal, not a carrier policy. The rule is the FCC’s: Portability: Keeping Your Phone Number When Changing Service Providers.

Where Thumb Cellular customers usually go next
Thumb Cellular roams on Verizon’s network outside its home area, so the phone in your hand is already Verizon-compatible. These carriers will take it with no compatibility question.
