The Ontario driver's license has 15 letters and digits. The initialletter is the first letter of the driver's last name.
i.e. S for Smith, R for Roberts, B for Black and so on.
The four digits which follow that letter, indicate the name is thesame as all other names spelled the same way.
i.e. if the numbers following the S for the name Smith were 1234,then that would mean that every person with the name Smith wouldhave S1234 as the first letter and first 4 digits.
There are 5 digits as the next sequence. The last of those 5 digitsis 'attached' to the last sequence of 5 digits to indicate thedriver's date of birth. The second number in the last sequence of 5numbers indicates the gender of the driver. A male driver is 0; afemale driver is 5.
i.e. Smith the driver's date of birth is January 15, 1991. Smiththe driver is male. Smith's last 6 numbers of his driver's licensewill be: 9-10115.
There are 4 numbers in the driver's license which do not seem to beindicative of anything special and may be randomly assigned. I havebeen unable to find out what those 4 numbers mean or even if theydo mean something. So they MAY be random.
The result of this example would be a driver's license for Mr.Smith which might look like this: S1234-xxxx9-10115 where the xstands for numbers which might be randomly assigned.
If I can ascertain if the x actually designates something, I willbe back to improve this answer.
