In Canada, licence plate numbers are usually assigned in ascending order, beginning with a starting point such as AAA-001. Thus, someone familiar with the sequence can determine roughly when the licence plate was issued. After Ontario's transition to an ABCD-123 format in 1997, plates were issued in ascending order starting with AAAA-001. It took close to ten years to exhaust the supply of plate numbers with A as the first digit. In late 2006, plates with B as the first digit were assigned, and have continued from there sequentially. Plates with C as the first digit have been spotted in Ottawa and Toronto as of August 2016.
The gradual increase in the use of letters in the serials of licence plates has given rise to an increased possibility of unintentional profane or inappropriate words or messages arising from the use of sequential alphanumeric combinations. Thus, numbering sequences generally exclude certain combinations of letters or numbers that would be potentially offensive. Jurisdictions' attention to excluding offensive combinations varies widely, however. In 1986, Waldale, a Canadian licence plate manufacturer, due to a production error, produced an entire batch of New Brunswick plates that began with the letters ASS. The plates were issued, and were unofficially scrapped, but many found their way into the collectors' black market.
From 1971 to 1975, Manitoba's licence plate bore the slogan 'Sunny Manitoba: 100,000 lakes'  but was changed to 'Friendly Manitoba', possibly due to conflict with Minnesota's '10,000 lakes' slogan.
Driver’s licence number that is of great interest, often because it can serve as a unique identifier. In Alberta and British Columbia, the licence number is a unique number that has little or no significance or meaning in terms of other personal information attributes.
