Recycled phone numbers: what happens to a betting account tied to an old SIM
If your old number is reassigned, the new holder can receive the codes and messages meant for your betting account. The gambling law does not mention recycled numbers, so protection rests on the operator's identity checks and on you changing the number before you let the line go. Your mobile network sets its own recycling rules, so ask it.
What a recycled number is, and why it matters here
A recycled number is a phone number that a mobile network has taken back from one customer and later issued to another. For a betting account, that matters because the number is usually the contact point. If you stopped using the SIM but never changed the number on the account, the account still points at a line you no longer control.
The first step is to update the number while the old line still works, as set out in the guide on changing the phone number on a betting account. This guide covers what happens when that step was missed.
What the gambling rules say, and what they do not
Neither the Gambling Control Act, 2025 nor the operations regulations describe recycled numbers, dormant SIMs or network reassignment. Those matters sit with the mobile network and its own terms. This guide therefore states no recycling period and no network procedure.
What the gambling rules do set is the frame around the account. A person may take part only if registered and holding an account (Act s.72(1)), and an operator must require proof of age of majority before registration (s.72(3)). Regulation 85(2) requires identity checks against "reliable, independent and electronically verifiable data sources" before the account is activated and before any deposit is taken.
What can go wrong when the number changes hands
| Situation | Risk to the account | Rule or fact that applies |
|---|---|---|
| New holder receives a one-time code meant for you | A code could be used to reset a password or approve an action | Operators must use multi-factor authentication such as one-time passwords for online payments (Ops Regs r.49(c)). A code only protects you if it reaches you. |
| New holder receives marketing or alert messages | Your name, balance hints or betting activity are exposed to a stranger | Personal data of the player must be protected; see the guide on personal data terms. |
| Prize is paid to the registered wallet on the old number | A small-tier prize goes to a wallet you no longer hold | Ops Regs Third Schedule: small-tier prizes are paid automatically to the registered mobile money wallet or online gambling account. |
| Account is left idle for months | Balance is returned to you, but where it goes is unclear if your details are stale | Act s.77(1): after three months with no transaction the licensee remits the balance to the player. |
| Someone claims the account using your old number | An attempt to be treated as the registered player | Ops Regs r.85(3)-(4): winner identity is verified and verification includes official identification documents. |
The third row depends on how the operator is set up, so check the operator's terms rather than assuming one outcome.
Illustrative example
Illustrative example: a player stops using a SIM in January and opens a new line in March, but never updates the betting account. The old number is later issued to someone else. A login code sent for an old request now arrives on a stranger's phone. The operator still holds a verified name and ID for the account, so a properly run reset should ask for more than the code, but the player has lost the one channel the operator uses to warn them.
Steps to take now
- List what is tied to the old number
Check each betting account, the mobile wallet and any email or app that sends codes to that line. Old accounts you forgot are the usual gap.
- Update the number while the old line works
Use the operator's own app or customer care. The operator may ask you to verify your identity again, which is consistent with regulation 85.
- Ask your mobile network, not the operator, about the line
Ask whether the number is still yours, how long a lapsed line is held and whether it can be restored. Use the network's official shop or customer care, because the rules are the network's.
- Withdraw or note any balance
Money left on an idle account is easy to forget. The guide on inactive account balances explains section 77 in more detail.
- Tighten the other ways in
Use a strong password that is not shared with other services, and read the guide on protecting an account from SIM swap to secure whichever line you use now.
If you have already lost the number
If the line was lost, stolen or has been reassigned and you cannot reach the operator by the old route, contact the operator's customer care centre. Section 68(8) of the Act requires an online operator to maintain one in Kenya. Say that the registered number is no longer yours, and ask for the account to be protected until your identity is confirmed.
Follow the steps in the guide on lost or stolen phones as well. If activity you did not start has already appeared, go to what to do if a betting account is hacked.
If codes arrive for a stranger's account
If you have just been given a number and start receiving betting messages or codes, they are not for you. Do not tap links or share codes, and do not try to log in. The guide on receiving a betting OTP you did not request lists what to check.
Contact the operator named in the message through its own app or website, not through the number in the message.
If the operator will not fix your details
Write to the operator, keep a copy and ask for a written reason if it refuses. If a data problem remains, the Office of the Data Protection Commissioner accepts complaints through its official portal. The ODPC complaint page is listed in the sources below.

Questions and answers
Does Kenyan gambling law say anything about recycled phone numbers?
Not in the Gambling Control Act, 2025 or the operations regulations read for this guide. The rules that apply are general: a player must be registered with an account (s.72(1)), and identity must be checked using reliable, independent and electronically verifiable data sources (r.85(2)).
Can the new holder of my old number log in to my betting account?
Having the number is not the same as having the account. A login still needs the account credentials, and the operator must check identity under regulation 85. The risk is that a number-based reset or one-time code reaches the wrong person, which is why you should change the number on the account first.
How long does a network keep a number before reassigning it?
This guide does not give a period. The recycling and inactivity rules belong to your mobile network, and they should be read on its own official pages or confirmed with its customer care.
What happens to the money if I stop using the account?
Under section 77 of the Gambling Control Act, 2025, where no transaction has been recorded for three months the licensee must remit the balance to the player. If the player's whereabouts stay unknown for five years, the money is presumed abandoned and goes to the Unclaimed Financial Assets Authority.
What if I am receiving messages meant for someone else's betting account?
Do not use any code or link, and do not reply. Tell the operator named in the message through its own customer care channel that the number has changed hands.
Where can I complain if an operator ignores a data problem?
The Office of the Data Protection Commissioner accepts complaints through its official complaints portal, which its complaint page links to.
