Here is a very simple step to retrieve jamb E-pin if it is lost or you haven’t been given.
As described by a candidate
I actually paid for the e-pin online but I wasn’t given immediately. So I went to jamb office and I was showed how to retrieve it.
Go to this link>>> http://www.jamb.org.ng/eFacility/CandPay/InitPay#
