Dear aspirant !!

Hope you are doing well !

Registration is the act of enrolling in something, like a school . There is also registration for voters and drivers and people attending a conference.

Please clarify firstly for which school you are asking these things then only we can answer you properly.

Hope it helps you !

Thanks for asking!!

For registration number of any school please contact the school authorities for the details or visit the school website, if incase it's mentioned there. You may also contact the board of studies of school or the Educational board it's affiliated to for the registration number.
