Hello aspirant,

If You have done any mistake in the RRB PO Application form and if you want to correct it, then there is one solution for this problem - You can register again in the RRB PO Application form with new Mobile Number and Email ID, considering no mistake to be made this time. You cannot apply for the new form with the same email ID and mobile number as it was used earlier. This will noyt generate admit card. Apply again for RRB PO form with a new email ID and Mobile Number.

Furthermore, to correct any mistake in yoru RRB PO Form, there is another method and that is to provide an affidavit. You can make a 'Affidavit' from notary office which will resolve your mistake. This affidavit will work during online exam and also at the time of document verification.

I hope that this will help
