How to check the M-PESA number that sent you money

Start from your own M-PESA transaction, not a screenshot

Whether money really arrived is a question only your own account can answer. Open your usual M-PESA app, menu or statement yourself and find the transaction you are asking about. Read the amount, the date and time, the transaction code and the sender details that your own account shows.

A message, receipt image or screenshot that someone else sends you is a claim, not proof of payment. Its layout can be copied. Compare what you were sent with the transaction in your own account before you release goods, send a refund or believe that a payment has cleared.

Why the sender's number may show only some digits

Since 24 March 2026, Safaricom has masked the sender's full mobile number on M-PESA transaction notifications. As reported by Maudhui House, a 10-digit number is partially hidden, showing roughly the first four and last three digits — for example 0722***000. Safaricom said the change was approved by the Central Bank of Kenya and is intended to reduce unwanted contact, social engineering and the harvesting of phone numbers from transaction messages.

A partial or masked sender number is therefore normal and is not by itself a sign of fraud. Do not guess the missing digits, and do not search for or accuse an unrelated number that happens to fit the visible pattern.

Ask Safaricom for the sender's full details through *334#

Safaricom introduced a consent-based way to see full sender details. Maudhui House reported that a recipient who needs to confirm an unexpected payment can forward the transaction message to the short code *334#. The code sends a request to the sender, who can approve or decline releasing their own full name and number. The report described a limited verification window — up to 24 hours after the transaction, with a two-hour period for the sender to respond — and said the recipient is notified if the sender declines.

Use only the official channel. Do not install a third-party app, dial codes dictated by a caller, or share your PIN or one-time password with anyone who offers to "reveal" the sender for you. Safaricom's fraud-awareness pages state that Safaricom only calls from 0722000000 and that customers should not dial codes on instruction from a stranger. A request for your PIN to look up a sender is itself the fraud.

If the money was not meant for you, leave it untouched

An unexpected payment can feel like good luck, but it may belong to someone else. People Daily reported on 9 September 2026 that Kenya's Computer Misuse and Cybercrimes Act creates an offence for intentionally withholding an electronic payment delivered in error, carrying a fine or imprisonment, and that a court case had involved recipients who used money sent to them by mistake. The same report described separate, heavier penalties where funds are treated as proceeds of crime.

The safe response is to keep the money in your account and resolve it through Safaricom rather than by sending funds to a number someone gives you. Do not spend, withdraw or move it, and do not make a separate transfer to an unrelated number supplied by a caller. Ask Safaricom to handle the reversal through its official process.

If a sender asks you to reverse money by SMS (456)

Safaricom's own M-PESA reversal page explains the official do-it-yourself reversal: forward the original M-PESA transaction message to 456. Only the sender or the recipient of that transaction can request a reversal, the request must be made within 24 hours, the transaction must be a Safaricom-to-Safaricom P2P transfer, and up to three attempts are allowed. A reversal also depends on the recipient having enough balance.

Crucially, the other party can decline. People Daily reported on 9 July 2026 that Safaricom said it cannot force a reversal when the recipient refuses, and advises the parties to resolve it directly or to report the matter to the police, using an Occurrence Book number if it becomes a legal dispute. A request to reverse is a request, not an instruction that overrides your own check.

Check the number, then report safely

Search the number that messaged you, any number you were asked to pay, and any Paybill or Till on ScamBusterKE before you act on a claim about a payment. Community reports describe what people report; they are not a finding of guilt. No reports does not prove a number is safe, and a matching report does not by itself establish who sent a particular payment.

If you add a report, describe the request and what happened in neutral terms. Keep PINs, one-time codes, full receipts, account balances and identity documents out of the public description. Evidence uploads are private supporting material for moderation. If money has genuinely left your account, or your line may be compromised, contact Safaricom promptly through an official channel and consider a police report through the DCI.
