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.
Table of production times for different models of Opel vehicles:
|from construction year||until construction year|
|Astra A (F)||1991||1998|
|Astra B (G)||1998||2004|
|Astra C (H)||2004||2009|
|Astra C GTC||2005||2009|
|Astra C Convertible||2006||2010|
|Astra D (J)||2010|
|Tigra B (Twin Top)||2004|
Vehicle Identification Number:
Location of the VIN
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.

1.2.2 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.

2.2 Form and appearance of the factory plate
Adhesive label from MY 1998
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.
2.3 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.
3. Adrema Plate (Production Plate):
3.1 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.
3.2 Location of the Adrema plate
3.3 Appearance of the Adrema plates
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.
4. Engine Number:
4.1 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.
4.2 Location of the engine number
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
On the cylinder block in front of the clutch housing
4.3 Appearance of the engine number
Opel engine numbers are stamped or needle-punched on.
Engine numbers over two lines and engine numbers with the designation after the serial number are also possible (here on the Corsa D (Z14XEP)
4.4 Breakdown of the engine number
1 = Maximum exhaust values
A = Austria
C = Euro 1
E = Euronorm
S = Sweden “A10/11”
X = Euro 2 IAW Directive 96/69/EG
Y = Euro 3 IAW Directive 98/69/EG
Z = Euro 4 IAW Directive 98/69/EG
No letter, or letter cancelled out = no emissions class
2 = Engine size (ever x 100 cc)
Example: 20 x 100 cc = 2.0 litre engine
3 = Compression ratio (Compression group)
|G||Less than 8,5 :1|
|L||8,5 – 9 : 1|
|N||9 – 9,5 : 1|
|S||9,5 – 10 : 1|
|X||10,5 – 11,5 : 1|
|Y||More as 11,5 : 1|
4 = Fuel blending
|NG||Natural Gas (Erdgas)|
5 = Assembly Plant
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.
5. Gearbox number:
Gearbox numbers cannot be used for identification purposes, but a gearbox number attribution to a given VIN can be performed at the works.
5.1 Location of the gearbox number (Examples)
5.2 Breakdown of the gearbox number
1 = Assembly Plant
e.g.: A = Aspen , B = Bochum
2 = The day of the year
3 = Last number of the year
e.g. 7 for 2007
4 = Shift number at the works
1 or A = early shift
2 or B = late shift
3 or C = night shift
5 = Transmission type
6 = Individual works internal transmission designation
e.g. 7 = Overdrive or manual transmission
O = without locking differential
S = with locking differential
7 = Ratio (ring gear diameter)
e.g. 394 = 3.94
6. Radio Number:
As of Model Year 1989, Opel passenger vehicles have been fitted with radios and/or CD-players at the manufacturing plant, on which a standardised individual number is stamped or stuck on. With the help of this individual number, the VIN can be traced up to a maximum of 10 years in the past.
6.1 Example of a radio number
Example: Example: The model NCDC 2013 (Quadruple CD changer with navigation)
