Driving License Numbers: Formats, Variations, and Randomization

Technically speaking, the format and number of digits in a driving license number can vary significantly depending on the country and even the state or province within a country. For example, in the United States, drivers license numbers can range from 1 to 9 digits, and in some cases, they may include letters. Similarly, in the United Kingdom, the number is 16 alphanumeric characters. In Canada, the number can range from 6 to 15 characters, varying by province.

State-Specific Formats in the U.S.

The format within states can also differ. For instance, in the State of California and Pennsylvania, the driver's license numbers typically consist of a mix of digits and letters. In Pennsylvania, the number is comprised solely of digits, whereas in California, it includes one letter and seven digits. However, it's important to note that these formats can have changed over time. For example, in the 1970s, when the author lived in New Jersey, the number appeared as a single letter followed by 14 digits.

UK Driver License Number Format

In the United Kingdom, the driver's license number format is more standardized. It consists of 16 characters, which can be a mix of letters and numbers. However, the utility of this format for residents of Quebec might be limited due to the vast differences in driving regulations and recognition between regions.

Uniqueness and Randomization

While a significant portion of the driving license number can be predicted based on specific criteria, such as the digits and letters derived from one's surname, date of birth, initials, etc., the last two digits are random. Since June 2015, there is no longer a need to retain the paper copy of the driving license, and the photocard is sufficient for all purposes, including the driving test. In the UK, it's not mandatory to carry the driving license while driving, but if you are stopped by the police, you must produce your driving license within 7 days.
