To change a Boost Mobile phone number, contact Boost Mobile Customer Support. As of April 2015, the toll-free General Support number is 1-866-402-7366 and is open Monday to Friday from 4 a.m. to 8 p.m. PST and Saturday and Sunday from 4 a.m. to 7 p.m. PST.

Not all physical Boost Mobile locations have the ability to change a phone number. Representatives at a brick-and-mortar location may have to call Corporate Customer Support to facilitate the number change.

When calling Boost Mobile support, it is necessary to provide some specific account information in order to validate identity and confirm that the changes requested on the account are authorized. Once a caller is validated and authorized, Boost Mobile asks for the Electronic Serial Number located on the back of the phone. The ESN is a unique code used to identify a specific cellular device on a network. To change the phone number tied to an ESN, the support agent releases the phone number currently assigned to the ESN and assigns a new number in its place. Generally, changing the phone number assigned to an ESN can take a few minutes to a several hours to fully register across the whole network.
