Here is how to get your BirchMobile account number and transfer PIN, and what to do with them when you move your number to another carrier.
Account Number
Porting requires your account number and telephone number, as well as a correct matching address. You must call Customer Service for the account number (after verifying that you’re the account owner).
Transfer PIN
Ask BirchMobile for the transfer PIN. There is no default PIN — do not guess one.

Check coverage before you port
BirchMobile runs on the T-Mobile network, so the coverage you get at your address is T-Mobile coverage. Check it on T-Mobile’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.

Questions about BirchMobile
Can I keep my phone number when I leave BirchMobile?
Yes. Federal number portability rules let you take a working number to a new carrier. BirchMobile cannot refuse the transfer or charge you to release the number.
Should I cancel BirchMobile before I port my number out?
No. Cancel first and the number is released, which ends your right to move it. Keep the BirchMobile line active until the new carrier confirms the port completed.
How long does a port out from BirchMobile take?
A simple wireless transfer usually completes within one business day once the new carrier submits the correct BirchMobile account number and transfer PIN.
Does BirchMobile run on its own towers?
No. BirchMobile is a reseller riding on the T-Mobile network.
