How to Notify Three After a Death in the UK
If the person who died had a Three mobile, broadband or smartwatch account, you can tell Three using its bereavement form or by calling its bereavement team. The main decision is whether you want to close the account, transfer it to someone else, or move the number to another network before anything important is lost.
Dealing with a phone account can feel small compared with everything else after a death, but it often is not. A mobile number may still be tied to banking logins, two-factor codes, family contacts, voicemail messages and household bills. It is worth slowing down and making the right decision before the account is closed.
What Three lets you do after someone dies
Three says you can usually do one of three things:
- close the account
- transfer the account ownership to someone else
- move the number to another network provider
That choice matters. If you close an account too early, you may lose access to a number that is still being used for account recovery, text-message verification or saved voicemail. If another person in the household needs the service to continue, a transfer may be the better route.
How to notify Three
Three’s official options are:
- complete the online bereavement form
- call the bereavement team on 0333 338 1400
Three says the phone line is open 08:00 to 20:00 Monday to Friday and 09:00 to 18:00 on Saturday and Sunday.
The online form is usually the clearest starting point because it lets you upload the death certificate and say exactly what you want to happen to the account. If you ask to transfer the account or move the number to another network, Three says it may need to contact you and that it aims to do so within 48 hours. The form also says it will email within 5 working days to confirm changes.
What information and documents you need
Three asks for the deceased person’s:
- account number or mobile number, if known
- full name
- date of birth
- address
- death certificate number
- registrar’s name
- district where the death certificate was issued
You should also expect to provide your own contact details and, if using the form, upload a copy of the death certificate.
Before you start, it helps to gather:
- the phone or broadband account details
- the death certificate
- the account holder’s address and date of birth
- a note of what you want to happen to the number
- a list of any other linked Three numbers on the same account
Should you close the account, transfer it, or move the number?
This is the part that matters most.
Close the account
This is usually right if nobody needs the service anymore and the number is not tied to anything important. Three says that if the account is cancelled without moving the number elsewhere, it will usually set the cancellation date to the next bill date.
Transfer the account to someone else
If a partner, child or other family member still needs the service, you may be able to change ownership instead. Three says this can be subject to a successful credit check.
Move the number to another network
If the number needs to be kept but not with Three, Three says the account will be cancelled when the PAC is used. If the PAC is not used, it says the account will be cancelled 30 days after the PAC was requested.
That 30-day window is important. Do not request a PAC and then forget about it.
Important things people often miss
Voicemail can be lost
Three warns that once the account is closed or transferred, you will lose access to any personalised voicemail messages linked to that number. If there is anything you may want to keep, try to save it before submitting the form.
You usually do not need to return the device or SIM
Three says it does not normally ask for the device or SIM to be returned as part of the bereavement process. The SIM will stop working once the account is cancelled.
Pay Monthly cannot be switched to Pay As You Go in this situation
Three says it cannot move a Pay Monthly account to Pay As You Go when the account holder has died because of system limitations. If your real goal is keeping the number, ask instead about a change of ownership or moving the number with a PAC.
Overseas deaths can still be dealt with
If the person died abroad, Three says it can still process the request, but it will need the death certificate. If you need the account to stay active a little longer while arrangements are made, tell them that clearly.
What about final bills, refunds and balances?
Three says any outstanding balance will be cleared at the point of cancellation. It also says it cannot send refunds by cheque, but it can process refunds directly to the executor of the estate once it has the relevant information.
That means it is sensible to keep a note of:
- any final bill issued
- the date the account was actually closed
- whether a refund is due
- who Three says it can pay the refund to
A simple order to follow
If you are not sure where to start, use this order:
- Check whether anyone needs the number, broadband or device line to stay active.
- Save anything important tied to the account, especially voicemail and recovery access.
- Gather the death certificate and account details.
- Decide whether you want closure, transfer, or a PAC to move the number.
- Submit the bereavement form or call Three’s bereavement team.
- Keep the confirmation email or final bill for your records.

Final thought
Notifying Three is usually straightforward, but the real risk is rushing the decision. Before you close anything, think about the mobile number, voicemail, account recovery and whether someone in the household still depends on the service. A ten-minute check now can save a lot of frustration later.
