What character must replace the 9th position in a driving licence number?

In a driving licence number, the 9th position is specifically reserved for the digit 9. This is a standardized practice to help ensure consistency and simplicity in the structure of driving licence numbers. The presence of this digit serves to allow for effective processing and verification by various agencies and databases that handle driving and licensing information.

While it might seem plausible for the 9th position to accommodate letters or other digits, the established format dictates that it must be a 9. This is crucial for identifying legitimate driving licences and enables easier tracking of records associated with a driver.

Other characters such as letters, digits between 0-9, or symbols do not adhere to the required structure of the licence number at this specific position in the sequence, as per the standard design. Thus, replacing the 9th character with anything other than the digit '9' would violate the regulatory format for driving licence numbers.
