The registrar of JAMB, Ishaq Oloyede, who stated this while briefing journalists in Abuja on Saturday, said the move was to provide more time for candidates to get their national identification numbers.
He said the suspension was also to address the technical challenges experienced at some centres.
He asked candidates to disregard the use of NIN for the 2020 registration and strictly comply with other procedures for the registration. He however said that JAMB will consider the use of NIMC for 2021 exams.
The 2020 UTME and DE registrations exercises are scheduled to begin on Monday, January 13 and end on February 17 across the country.
