What your Alberta driver's license number tells you

Your Alberta driver's license number is an eight-character code printed on the front of your card. It is not randomly assigned — each part of the number carries information about you, including your last name, birth date, and sex. Understanding what each section means can help you verify your license is correct or explain your number to someone who needs it.

Alberta's numbering system has been in place for decades and remains the standard for all current licenses issued by Alberta Transportation and Economic Corridors. The number stays the same throughout your life unless you change your legal name or correct an error on your license.

Key Takeaways

  • Your Alberta driver's license number is eight characters long and encodes your last name, birth date, and sex.
  • The first four characters are derived from your last name using a specific algorithm that converts letters to numbers.
  • Characters five through seven represent your birth date in a compressed format (year, month, day).
  • The final character indicates your sex and serves as a check digit to catch errors.
  • You cannot request a different number, and the number does not change when you renew your license.

How the first four characters encode your last name

The first four characters of your Alberta driver's license number come from your last name. Alberta uses a modified Soundex algorithm, which converts letters into numbers based on how they sound when spoken aloud. This system allows the province to assign a unique numeric code to nearly every surname.

The first character is always the first letter of your last name converted to a number (A=0, B=1, C=2, and so on through Z=25). The remaining three characters are generated by grouping the other letters in your last name by sound category and assigning them numbers. Letters that sound similar — like B, F, P, and V — all map to the same digit.

If your last name is short, the remaining positions are padded with zeros. This means two people with very different last names might share the first four characters of their license number if their names sound similar enough. That is why the remaining four characters (birth date and sex) are critical to making each number unique.

Characters five through seven: your birth date

The fifth, sixth, and seventh characters of your license number represent your birth date in a compressed format. Character five is the last digit of your birth year (so someone born in 1987 would have a 7, and someone born in 2005 would have a 5). Characters six and seven are your birth month and day, each represented by a two-digit number.

For example, if you were born on March 15, 1992, characters five through seven would read 2-03-15. If you were born on December 8, 2001, they would read 1-12-08. This compressed format allows Alberta to fit your full birth date into just three characters while keeping the overall license number to eight digits.

The final character: sex and error detection

The eighth and final character of your Alberta driver's license number indicates your sex and also functions as a check digit. For males, this character is an even number (0, 2, 4, 6, or 8). For females, it is an odd number (1, 3, 5, 7, or 9). The specific digit is calculated using a mathematical formula that includes all the previous seven characters.

This check digit serves as a safeguard against data entry errors. When Alberta staff or a business reads your license number into a computer system, the software can verify that all eight characters are correct by recalculating the check digit. If the number you provided does not match the expected check digit, the system flags it as a potential error.

What happens if your name or birth date changes

If you legally change your last name — through marriage, divorce, or a court order — you must explore for a new license with a new number. The new number will be generated based on your new last name and will be different from your previous one. You will need to bring proof of the name change (such as a marriage certificate or court order) to Service Alberta when you explore.

If an error is discovered in your birth date on your license, you can request a correction. You will need to provide proof of your correct birth date, such as a birth certificate. Once corrected, your license number will be recalculated to reflect the accurate information. Corrections are free, but you will receive a new physical card with the corrected number.

Where to find your license number and how to use it

Your Alberta driver's license number is printed on the front of your card in the upper right corner. It is also listed on your paper receipt if you have a digital license through the Alberta One Key app. When you need to provide your license number — to a rental car company, insurance provider, or government agency — always double-check that you are reading all eight characters correctly, including zeros.

Some businesses may ask for your license number over the phone or online. Only provide it to organizations you trust and that have a legitimate reason to request it. Your license number, combined with your name and birth date, can be used to look up your driving record, so treat it with the same care you would your Social Insurance Number.

Frequently Asked Questions

Can I request a different license number?

No. Your license number is generated automatically based on your legal name and birth date. You cannot request a different number, and Alberta does not issue vanity or custom license numbers for driver's licenses (only for vehicle license plates).

What if I was born on a leap day (February 29)?

Your license number will show 02-29 for the month and day characters, the same as anyone born on February 29. This is encoded directly into your license number and does not cause any issues with the system.

Does my license number change when I renew?

No. Your license number remains the same for life unless you change your legal last name. When you renew your license, the new card will have the same eight-character number printed on it.

Why do two people I know have the same first four characters in their license numbers?

This can happen when two people have last names that sound similar enough to produce the same Soundex code. The system is designed so that the birth date and sex characters (the last four digits) make each number unique. If two people had identical license numbers, it would indicate an error.

Is my license number the same as my driver's license record number?

No. Your license number is the eight-character code on your card. Your driver's license record number is a separate identifier used internally by Alberta Transportation and Economic Corridors to track your driving history and vehicle registrations. You typically only need the eight-character number for everyday use.
