what is driving licence number

A Driving Licence (DL) number is a unique alphanumeric code assigned to every licence holder in India, which serves as a crucial identifier for their driving credentials. The standard format is typically 16 characters and is structured to encode specific details. It generally begins with a two-letter state code, followed by a two-digit Regional Transport Office (RTO) code, the four-digit year of issue, and concludes with a seven-digit unique serial number. This unique code is essential for verification, maintaining driving records, and is used as a form of secondary identification.
