OPEL motor cars can be identified from the following numbers:

Location . Vehicle Identification Number (VIN)- stamped on the vehicle- on the factory plate- on the production stickers

Production number/ Order number

(PA Number on the ADREMA plate)

– on the upper spoiler , Engine Number- on the engine blockRadio and CD changer numbers (from construction year 1989)- on the radio and CD changer


The appearance and format of the data carriers on Opel vehicles (e.g. identification letters in the VIN, the appearance of the punched numbers, format of the type plate and the Adrema plate) vary greatly because production is carried out worldwide.

In the engine block production glues can be, the parts the VIN or a production number contain. With the help of this number can do with the Opel work conclusions on a certain vehicle pulled are limited or the number the possible passenger car on a few become.

Specific feature:

In vehicles, for him Swedish market are determined, is in the boot 2nd VIN

 Appearance of the VIN

The numbers are mostly stamped; on the Opel Tigra A they may be embossed. According to Opel, punched VINs were also used at the Luton works. As a rule, the Vehicle Identification Number (VIN) is stamped in a straight line, with equal spaces between each character.

The VIN has a special symbol at both ends. This can be a diamond shape, a six pointed star, an “X“, the acronym “GM” or a four pointed star shape.
At the works, if a mistake is made when applying the VIN, the erroneous VIN is crossed or barred out and the correct VIN placed next to it.

The Arena was produced together with an identical looking Renault vehicle, i.e., the VIN also resembled a Renault VIN and the factory plate as well also resembled a Renault factory plate.
Etched and not painted over (Aluminium)
The VIN on the Opel Sintra is written in dots and very untidily stamped. As the vehicle was built in the USA, the VIN looks different.

Frontera B:

Visible VIN

There is in addition a second VIN behind the windshield on some of the older models such as the Sintra and Frontera, as well as on the majority of newer models, such as e.g. the Astra (except for the Coupé and Convertible), Zafira B and Meriva. This is the so-called visible VIN. It is on a small riveted metal plate or on a sticker in both bar code form and in clear text. Some newer models, Such as e.g. the Tigra B, still do not have a visible VIN.

Under the pulled through line information to the color type (Y=Standard, Z=Metallic, with newer vehicles not compelling), to the color code (3-figure number) as well as to the drive GM is a code ( Interior equipment color) available.

 Type plates in Opel vehicles modified for natural gas

Opel vehicles with an OSV GmbH (Opel Special Vehicles) natural gas fit installed at the works have a second type plate on the right-hand B-spar with a different VIN (in particular another World Manufacturer Identifier Code (WMI) and serial number).
This is because of a so-called two-stage approval procedure: alongside the general certification, shown on the original Opel type plates, there is a second certification/approval for the modification for natural gas use, shown on the second type plate. The company Opel Special Vehicles (OSV) uses the WMI “W0S” and puts a “V” at the fourth character of the VIN. The letters and numbers for the type, model and model year are identical, the works letter and the serial number however are different from the original Opel VIN.

Adrema Plate (Production Plate):

In General

Adrema plates are not subject to any statutory regulations and may differ within the individual plants and be altered if required. The data they contain serve solely to control the production process.

Until recently Opel used to fit a production purchase order (PO) number plate (= Adrema plate) in all cars, which was painted over in the colour of the car. Adrema plates in the FRONTERA and MONTEREY however, are not overpainted but are silver in colour.

New models, starting in 2000 normally do not have an Adrema plate (although the Zafira and Antara is an exception to this rule). But the space on the radiator yoke where they used to go an Adrema plate is still present.

 Location of the Adrema plate

Normally on the radiator yoke
The Vivaro is an exception: it is on the right B-spar beneath the type plate

The characters are embossed. The metal plate is fastened with rivets.

Not all equipment features are shown on the plate because the basic models of the LS or GL vary a lot in the kind of fittings they have.

Exception – Opel Monterey:
The Adrema plate with the complete VIN is black and attached using adhesive tape (not riveted)
(not riveted)
Exception – Opel GT (Wilmington/USA works):
A sticker with the complete VIN in the glove compartment

Engine Number:

Vehicle identification using the engine number

The engine number is not identical with the number at the end of the VIN.

Identification is possible, with the complete engine number, through the manufacturing plant.

 Location of the engine number

Petrol engine:

Stamped on the cylinder block below the cylinder head

– on longitudinal engines on the left in the direction of travel

– on transverse engines at the front bottom right (as viewed when standing in front of the vehicle).

An example of a transverse engine (Astra C): Under the dipstick holder

4.5 Engine number sticker

All new vehicles have a white paper sticker on the engine block showing the complete engine number (in full and as a barcode strip). The sticker is not particularly adhesive and so many of them fall off quite naturally as they get older.

Attention: The sticker on the Opel GT does not contain the engine number but other information, among other things the date the engine was built.
