The Indian Driving Licence (DL) number is typically a 16-character alphanumeric string, which includes a hyphen (-) or a space as a separator. Although it is sometimes referred to as a 15-digit format, the complete valid number, including the separator, totals 16 characters. This standardized format allows for easy identification and includes components such as:
- Two characters representing the State Code.
- Two digits for the Regional Transport Office (RTO) Code.
- Four digits indicating the year of issue.
- Seven unique serial digits for the license.
