Candidates who have entered wrong date of birth and wrong course can now follow the steps outlined in this post to do their National Youth Service Corps (NYSC) correction of date and wrong course. https://www.myschoolgist.net/nysc-portal-how-to-correct-date-of-birth-and-wrong-course/

Henceforth, information from the West African Examination Council (WAEC) will now be used to effect changes on the NYSC portal as from the 2017 Batch 'A' online Registration.

The link above also contains a special guide on how to buy the WAEC Verification PIN online or using the bank option.

What if I didn't use waec can I still use the verification pin

Sorry, I don't understand what you mean, but I think you want to know if your age will be fetched from WAEC if you enter the PIN, if am correct, it is yes, and possible only if you wrote WAEC.

What if I didn't use waec can I still use the verification pin

I wrote waec but it was nabteb I used in processing my admission, the result on my school portal is nabteb, that's why I'm asking if I can use the waec verification pin when I didn't use waec to enter school

And please how long does it take for course correction to reflex
