Sending money mistakenly is common for both M-PESA and Airtel Money Kenyan users. In such a case, you do not have to lose your money when there are channels for reversing money.
It is advised that you take immediate action as it significantly increases the likelihood of a full recovery.
Both Safaricom and Airtel have established structured protocols to freeze and retrieve these funds.
Below is the definitive, 2026 step-by-step technical guide to executing a reversal on Kenya’s primary mobile money networks.

Note: For business or merchant payment errors, refer to the step-by-step process to reverse money sent to wrong till and paybill numbers.
1. How to Reverse an M-PESA Transaction (Safaricom)
Safaricom offers three official channels to reverse peer-to-peer (individual) transactions. Time is a critical factor; your request should ideally be initiated within 24 hours of the transfer.
Method A: The 456 SMS Reversal (Fastest)
This is a free, automated self-service channel available 24/7. It is the most efficient way to freeze funds before the recipient can withdraw them.
- Locate the official M-PESA text confirmation message in your inbox.
- Forward the entire, unedited message to the shortcode 456.
- You will receive an immediate acknowledgment SMS from Safaricom stating that the reversal process has commenced.
- Safaricom will reach out to the recipient to verify the error. If uncontested, the funds are typically credited back to your account within 2 to 24 hours.
Method B: USSD Self-Service (*234#)
If you accidentally deleted the confirmation message but still require immediate intervention, use the USSD menu.
- Dial *234# from your Safaricom line.
- Select My M-PESA Information (Option 2), followed by M-PESA Reversal (Option 5).
- Alternatively, look for the Self-Service option depending on the menu updates, and select Reverse Transaction.
- You will be prompted to input the unique 10-character M-PESA transaction code (e.g., SLK4H7R2T1).
Method C: Direct Customer Care Channels
If automated systems fail, or if the transaction requires human intervention:
- Call 234: This is a dedicated, toll-free M-PESA support line. Speak directly to an agent, providing the transaction ID, the wrong recipient’s phone number, and the exact amount sent.
- The MySafaricom App: Navigate to the M-PESA tab, view your transaction history, select the specific transaction, and tap the “Reverse” button to log an instant ticket.
2. How to Reverse an Airtel Money Transaction (Airtel Kenya)
Airtel Kenya provides a robust self-service platform designed to resolve erroneous individual transfers directly from your handset.
Method A: USSD Self-Service (*185#)
The most reliable and direct method for an Airtel Money reversal is managed via the network’s primary financial menu.
- Dial *185# on your Airtel line.
- Select Airtel Money or navigate directly to Self-Help/Customer Care (usually Option 10 or designated as Self-Service).
- Select My Transaction Reversals.
- Choose Initiate Transaction Reversal.
- The system will display your recent transactions. Select the specific erroneous transfer you wish to claw back.
- Enter your Airtel Money PIN to authenticate and authorize the reversal request.
Method B: Customer Care Assistance
If the USSD portal is inaccessible or the transaction does not appear in the recent history menu:
- Dial 100 from your Airtel line to connect with Airtel Customer Care.
- State the nature of the error clearly and provide the transaction details, including the reference ID and the unintended recipient’s mobile number.
Important Rules You Need to Know
While Safaricom and Airtel will help you reverse the money, you need to keep these three strict rules in mind:
1. The Person You Mistakenly Sent Money Must Agree
Safaricom or Airtel cannot just take money out of someone else’s wallet without talking to them first. They must call the person who received your money to get their permission.
If that person has already withdrawn the cash or refuses to give it back, both safaricom and Airtel are not allowed to force a reversal without a court order.
2. Keeping Money Sent Mistakenly is a Crime
If someone receives your money by mistake and refuses to return it or spends it, they are breaking the law.
Under Kenyan cybercrime laws, keeping money sent to you by mistake is a criminal offense. If they refuse to cooperate, go to the nearest police station, file a report, and get an OB Number.
You can then take this OB number to Safaricom or Airtel so their fraud teams can track the user.
3. You Cannot Reverse Airtime if You’ve Spent it
If you accidentally bought airtime instead of sending cash to a person, you can only get a reversal if that airtime is 100% untouched.
If you use even one shilling of it for a text, call, or data, the transaction is locked and cannot be reversed.
