You can leave a family plan and keep your number in one of two ways. Move it to a different carrier, which needs the account number and transfer PIN from the account owner. Or take the line over at the same carrier with a transfer of responsibility, which the account owner has to approve. Sort out any phone balance first, since it usually comes due when the line leaves.
Your two options
| Move to a new carrier | Take the line over at the same carrier | |
|---|---|---|
| What you need | Account number and transfer PIN | The account owner's approval |
| Phone balance | Usually comes due | Can often move with the line |
| Your number | Comes with you | Stays the same |
| Credit check | Depends on the new carrier; prepaid needs none | Usually, for postpaid |
Moving your number to another carrier
- Ask the account owner for the account number and a transfer PIN for your line. Most carriers create the PIN in their app.
- Check whether your phone is paid off and unlocked.
- Sign up with the new carrier and choose to keep your number.
- Enter the account number and PIN. Your line leaves the family plan when the transfer finishes.
Prepaid carriers make this easy because each line is its own account. On Visible, every line has its own login and bill, so nobody else holds your PIN again.

Taking the line over at the same carrier
Verizon, AT&T and T-Mobile all let an account owner hand a line to someone else, who becomes responsible for it on their own account. Each carrier calls it something like a transfer of responsibility or transfer of ownership. The new owner usually goes through a credit check, and the line moves to a plan for one, which can cost more per line than the family plan did.
What it costs you and the family
| Before (4 lines on Verizon Unlimited Plus) | After you leave | |
|---|---|---|
| The family's 3 lines | $45 a line | $55 a line: $165 total, about the same bill for one less line |
| You on Visible | $25/mo, taxes included |
Talk to the account owner first
- The remaining lines may pay more per line once yours leaves.
- Any phone balance on your line usually comes due when it moves to another carrier.
- Shared perks, like streaming services, stay with the account owner.
Taking shared things with you
- Contacts, photos and messages live in your Apple or Google account, not the carrier's, so they come with you.
- Shared streaming perks and family cloud storage stay with the account owner.
- If your phone is financed on their account, agree who pays the balance before you move.
Under 18, or added as an authorized user?
Carriers usually need an adult account holder. If you're not on the account as an owner or manager, you'll need the owner to create the transfer PIN or approve the transfer.

Common problems
| Problem | Fix |
|---|---|
| The owner won't share the PIN | You can't port without it. Ask them to create a PIN just for your line, or to transfer the line to you. |
| The transfer of responsibility fails the credit check | Ask about a deposit, or move to a prepaid carrier with no credit check. |
| Your phone is locked to the family's carrier | It has to be paid off first; agree with the owner who pays. |
