Alabama registers vehicles under a staggered registration system, January through November, based on the first letter of the owner's last name. Motor vehicle registrations expire on the last day of the designated renewal month. For example, someone whose last name begins with the letter F, G, or N is required to register his or her vehicle in the month of April, and the previous registration expires on April 30.
Leased, commercial, and fleet vehicles are subject to renewal in the months of October and November and the registrations for these types of vehicles expire on November 30. Vehicles registered pursuant to the International Registration Plan (IRP) are assigned renewal registration months by the department.
