Your Comcast / Xfinity account number is found on the top-right corner of each bill you receive, and there is one account number for each billing address. Your account number is created when you sign up for any Comcast service and does not change. Each XFINITY Voice account has a single four-digit Voice Security PIN that protects access to voice features online and over the phone. If you are a new customer, you should have received your Voice Security PIN via an automated phone call or by mail. Before you can access certain details about your voice service, including billing details, voice information and voice features, you may be asked to provide your Voice Security PIN. Online, your account number is associated with XFINITY usernames for each person on your account. Each XFINITY username has a contact email address, a password and a secret question and answer (in case you lose your password). The primary XFINITY username is the main username for the account.
Call TracFone and ask them to release your number for porting. Tracfone account # is NOT the phone number. It is the MEID or IMEI serial number of the phone (this can be found on the back of the phone itself – under the battery, so remove the battery!) Or, if your are using a BYOP SIM Card, it will be the last 15-digits of your SIM Card number. You can also view the account number in the My Account section of the TracFone website by clicking “Add (or Edit) Nickname”. – TracFone doesn’t use passcodes, use 0000 if the operator you are porting to requires a passcode.
Twigby does not have a Customer Service number listed. To port out, you will need the 4 digit Twigby account number, MDN, address and zip code. (customers can log in at https://www.twigby.com/signin/login) There is no individual PIN so Twigby uses 1234. If you need help getting your account information, you can use the chat box on their website.
A four digit PIN and the Account # are needed to port out from U.S. Cellular. The customer’s account number can be found on their bill statement or online under account info, after you sign in. If you do not remember your PIN you can call U.S. Cellular customer service.
