A vehicle registration plate, also known as a number plate (British English) or a license plate (American English), is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes.
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.
In Canada, licence plates are issued by an agency of the provincial or territorial government. Generally, the appearance of plates is frequently chosen to contain symbols, colours, or slogans associated with the issuing jurisdiction.
