Contact TracFone and request the release of your number for porting. Your account number is NOT the Phone Number; instead, it is the MEID or IMEI serial number of the phone, which can be found on the back of the phone itself under the battery (remove the battery to locate it!). Alternatively, if you're using a BYOP SIM Card, the account number will be the last 15 digits of your SIM Card number. You can also access the account number in the My Account section of the TracFone website by clicking 'Add(or Edit) Nickname'.The passcode can be found on your online TracFone My Account page under 'Update Personal Profile', where it's listed as the Security PIN. If this field is blank, make sure to set up a passcode PIN before initiating the porting process.
