Get it done. add a surname. it will be better for you in the future and save you from unnecessary hassle. I got mine added.
hereβs what I did.
– advertised in the newspaper.
-got it published in the Gazette
– based on the Gazette notification, get your Aadhaar updated.
-then PAN and Passport after that.
names of the school/ college certificate can me done later on or a letter can be added with proof stating name change/surname addition when applying for jobs/university etc.
