What happens to a phone number?

A phone number depends on its carrier service and account arrangements. Before canceling a line, ask about keeping or transferring the number. Move your own account recovery methods first, so important accounts do not depend on a number you are giving up.

Steps

  1. Find the carrier and account owner

    Check whose name is on the mobile bill and which company supplies the service. Write down the carrier's name and support route. A person who uses a handset may not be the person who controls its carrier account.

  2. Decide whether the number should stay

    Consider family contact, messages and your own account recovery settings. Make a separate choice for the number and the physical phone. Keeping a handset does not tell the carrier what should happen to the line attached to it.

  3. Review accounts that use your number

    While you manage your own accounts, check which use the number for recovery or verification. Arrange another supported route before giving the number up. Use our two-factor guide for the account settings, without recording any security codes here.

  4. Ask about transfer before cancellation

    For a move to AT&T, the company says the old service must stay active during transfer. Ask your own carrier which process applies. Do not cancel first and assume that a later call will recover the same number.

  5. Use the carrier's after-death route

    Verizon offers transfers to another Verizon account. T-Mobile offers line transfers to an account in the requester's name. Your family should follow the relevant carrier's instructions and explain what they want to keep before requesting a disconnection.

  6. Preserve the memories separately

    Save the voicemails or messages you want preserved while you control the account and device. Check the voicemail guide before changing service. Ask the carrier what a transfer would do to the mailbox.

  7. Leave an instruction your family can find

    Record whether to ask about keeping the number, the carrier name and where your billing papers are. Leave credentials out. Review the active-line plan with the person you choose, so they know which company to contact.

Good to know

Should my family cancel the line immediately?

Ask the carrier about transfer and saved messages before cancellation. Your instructions can state that you want them to make that inquiry first. There is no single cancellation rule in this guide that applies to every family account.

Can a family member keep the number?

Some carriers provide a transfer route after a death. Verizon and T-Mobile describe those options in their help pages. The person requesting the transfer must follow that carrier's process.

Does keeping the number preserve every message?

Do not assume that it does. Save the particular memories you want and ask about mailbox effects before service changes. Our linked carrier guides explain the supported processes without promising that a number transfer keeps every item of data.

Should I write down my carrier PIN?

Keep it out of this checklist and this website. Record the company, the account owner and the location of relevant paperwork. Provide sensitive verification information only through the carrier's own secure process when the carrier requests it.

What should I do while I can?

Check the recovery settings on your own important accounts. Add supported alternatives, preserve chosen messages and tell your family your number preference. Those are separate tasks, so completing a phone transfer alone would not complete your account plan.
