Province code
AO Aosta
On Italian plates registered up to 1994, the code AO marks the province of Aosta, in Valle d'Aosta.
What it looks like
Provincial plates used three formats: the code plus six digits, the code with digits and a trailing letter, or the code with a leading letter and five digits.
AO 123456AO 12345AAO A12345
Modern plates carry no province code
Since 1994 Italian plates have been sequential nationally: two letters, three digits, two letters, with no geographic reference at all. A modern plate cannot be traced to a province, and anyone claiming otherwise is guessing. The code on the blue side sticker, where present, is optional and can be changed by the owner.
Check the vehicle's history
The province tells you where a car was born, not how it has lived. Real mileage, accidents and liens need the VIN.
17 characters. Field E on the registration document, or the base of the windscreen.

The VIN still decodes, but the archives we query hold less history for these vehicles.
