Kenya Power has released the only two M-Pesa Paybill numbers that customers should use when buying tokens and paying bills.
The company has cautioned customers that the only two numbers are 888880 and 888888 for pre-paid services and post-paid services respectively.
In a statement from the company, KP addressed a recent incident where some customers accessed the token system fraudulently.
"Investigations on allegations of fraud in the pre and post-paid billing systems at Kenya Power have been ongoing for several months now.
"The matter is currently being investigated by the Directorate of Criminal Investigations (DCI) due to the criminal nature of the fraud. We are giving the DCI all the necessary support and we are confident that now the net has been cast, the culprits will be caught and appropriate action taken," the statement reads in part.
