He said the IEBC did not expect to see such a big number of Kenyans transferring voting stations in the ongoing voter registration.
Kenyans who share national identity card numbers in the voter register should now expect an SMS from the electoral commission asking them to correct their details.
Andrew Limo, the manager for communication and public affairs at the Independent Boundaries and Electoral Commission (IEBC), said the body had picked their mobile phone numbers and was in the process of contacting those affected.
“The commission has now retrieved the mobile numbers of some 78,000 voters sharing ID cards and will shortly be sending them SMS to call them to update their records with us,” Mr Limo said.
“The requests for transfers are overwhelming and we did not anticipate the scale. There were large turnout towards the end,” he said.
The registration was scheduled to end on Tuesday but a court extended the deadline to Thursday to allow those who had been locked out of enlisting to get their voting cards.
The commission had targeted to register at least four million new voters and at most 6 million, a target it did not reach in the four weeks of mass registration.
At the same time, even as Kenyans are being rallied to register in large numbers, some expressed lack of trust in the electoral process, saying some leaders will steal votes come the August polls.
Some of the Kenyans interviewed said politicians always rig elections.
Speaking to the Nation while registering in Kahawa West, Nairobi on Wednesday, Evans Njoroge, 24, said he had delayed listing because he was busy with his business and did not trust the electoral process.
“I believe my vote matters, but then we are so used to leaders stealing votes that at the end it looks like my vote means nothing,” he said.
“I have never taken a voters card before because every time leaders get elected, they don’t do better and the same problems remain. But I think it’s important to have a card because it will be useful during campaigns,” Ben Gitaa said at Moi Avenue Primary School in Nairobi.
