Can we cancel the phone line yet? A free checklist for the person taking over
When someone who ran the household's tech is no longer around, cancelling their phone number feels like tidy, sensible admin. It can also lock you out of the bank, the email account and the password manager, because many of them send login or reset codes to that number. Tick what applies. You get a plain answer, "keep the line for now" or "safe to plan the cancellation", and a printable list of what to move first. It runs in your browser and nothing is sent anywhere.
Tick what applies and press "Check the phone line".
Why the answer is almost always "keep it"
Text-message codes are a weak but common way to prove who you are, and that is exactly why a number matters: sign-ins and password resets are sent to whoever holds it. Cancelling a line closes that route, and carriers may later reissue the number to someone else. The cost of keeping a basic plan for a few weeks is small next to the cost of rebuilding access to an email account. This tool therefore leans one way on purpose; it never says "safe to cancel" on its own, only that you can plan it once each item has a tested replacement.
Do this before you rely on it
- Check each service's own help page for how to change the contact number or add a second method. Steps change, and this page does not replace them.
- Tell the carrier only when the checklist is done. Ask whether a number can be paused, not closed.
- Write the result on the first page of your handover notes. Our free start-here sheet has a line for it, and the guide to what to write down explains where recovery codes belong.
- If you are the one who runs the household's tech, try the free gap checker to see which of these gaps you are leaving. The Handover Binder ($9) has a sheet for exactly this list.
This checklist is not legal, financial or telecom advice, and not a will.
