help on gro entry register

Have just failed to locate an ancestor

"Thank you for your recent application for the birth certificate of George
Cliffe.

The reference supplied was 1902 December Nottingham 7b 669.

Unfortunately, this reference does not relate to an entry containing the
above name(s). Our researchers have checked the indexes for the December
quarter of 1902 but found no trace of George Cliffe. Therefore, we are
unable to issue a certificate."

Can anyone help please?

He was 19 at the time of the 1901 census and born in Nottingham

Fred...

If he was 19 in the 1901 census why apply for a birth certificate for 1902
