Being able to decode the diverse markings on a car or part is important in establishing what type of car or part you have. This site is ane of the nigh comprehensive numbers decoding places available anywhere. From this page, y'all can quickly get to the specific codes. I endeavor and reply emails and decode specific requests, merely often you tin can discover the information here if you spend a couple minutes looking.
Above, left: A trim tag, lists original interior trim, exterior color, build date and other fisher body info.
Above, right: An engine showing engine suffix code and partial vin code.
You can verify the model of a car, or the originality of a machine. The primary number on a automobile is the VIN number. The VIN is the legal and almost accurate representation of the motorcar. This will tell a lot of information about the car itself, where it was built, what model it is and what engine originally came in the car (mostly or specifically afterwards 1972). A trim tag or body number tag is FISHER BODYS representation of the motorcar. Information technology is used to identify when the car was built and how the car (body) was originally fitted out, what type of seats, colors, etc... finally, the engine, manual and rear axle markings tell where the unit was made or assembled, when it was made, what the specific characteristics it is and usually what it was originally installed in. By decoding these items, yous tin can gather a lot of information most your car equally well as check the originality of a car. This is peculiarly helpful if you are checking out a "numbers matching" car where the asking price is usually higher. If whatsoever item appears to be amiss, y'all should exist VERY skeptical of the originality of the car. However, in some cases, legitimate changes could have been made (warranty work, production assembly line substitution, etc...) Most of this information pertains to the Chevrolet Camaro.
Delight note - this site is heavily slanted towards Chevrolet decoding with an emphasis on Camaros. 1970 to 1981 specifically. Decoding other cars is like but don't be surprised if you detect an omission here or there.
The VIN is the Vehicle Identification number. It is the legal definition of the car - regardless of everything else you're looking at. When you buy Whatever car, the VIN on the slice of newspaper in your hand MUST MATCH the VIN affixed to the machine. Otherwise you're dealing with ii unlike vehicles. And while information technology should be obvious - if you decode a Trans Am vin and you're buying a Camaro.... or you have what looks like a Nova sitting in the driveway, but the VIN decodes as a Monza... call back - the VIN is the car. And if the VIN says the thing is a Monza and you're trying to buy a Nova - nevermind the paperwork. Walk away.
The VIN is 13 digits long, until 1981 when information technology goes to 17 digits. "Carfax" needs 17 digits - therefore information technology tin't do anything with a pre-81 vehicle. The VIN is affixed to the auto with specific rivits called rosette rivits. It is non affixed with hardware store pop-rivits. If at all possible, never touch or remove the VIN from the vehicle for ANY reason.
In extreme cases where you have doubts nigh the validity of the VIN affixed to the vehicle (i.e. it'due south been tampered with or affixed with popular-rivits), yous would double check it against the hidden (or confidential) vin. This number will be stamped on the concluding substantial thing that'll become destroyed during the cars life. In the case of the Camaro - this is the firewall, BEHIND the heater box. The theory is - if the firewall is destroyed, the whole auto is gone. You won't accidentally fix and alter or obliterate the confidential vin during the repair process - so these numbers will ever match up.
Here's the hidden vin on a Camaro. The format is not the consummate VIN, simply enough to conclude the original VIN's number.
1 = chevy, 4 = model year, North = assembly constitute, xxxx = serial number of vehicle. (this will lucifer the VIN plate)
The VIN will incorporate MODEL data. The "SS", and "Z28" are Not MODELS. They are options. Options aren't coded in the VIN. However, get-go in 1972 when the specific engine is coded into the VIN, the ENGINE volition give away or hint at the option. These two choice packages required specific engines and the VIN engine lawmaking will boom down a Z28 or an SS. This becomes somewhat useless after 1974, simply helpful again in 1981. The Type LT and Berlinetta are Models and the VIN will reveal this.
The sequential number for the vehicle doesn't start at 000001. The Camaro more often than not starts at either 100001 or 500001, depending on year and assembly found. This way if the plant is building 3 unlike vehicles, each vehicle line will be in a unique sequential range - Camaros at 100001, Novas at 300001, Impalas at 700001, etc... The first 10 or xx cars are usually pilot cars and go to places other than dealers.
The VIN Number breakup for specific year Camaros is located under each twelvemonth Camaro information as the data contained in the VIN changes from yr to twelvemonth. The VIN on the 1967 Camaro is on a stainless steel plate rivited within the drivers door jamb. All other models take the VIN located on a plate visible through the windshield on the drivers side dash panel.
| VIN info from 1967 - 1971 were in the same format. The breakdown is as follows: |

The Cowl or Trim tag is FISHER BODYS representation of the Trunk. Not a vehicle, but a shell. In Summary, Fisher body doesn't intendance if this is a Camaro or a Firebird. They need to know what color to paint the thing and what style & color interior to put into it. Annihilation related to their assembly of the affair and what they demand to know is represented on information technology. After they're done with information technology, information technology gets the Division specific goodies.
I say this because fisher body doesn't care if this is a Z28. Merely they'll demand to know to paint the stripes on one. Aforementioned matter with the big block super sport... this had a blackness painted tail panel - and then it'll be indicated (on norwood built cars. LA didn't code the tag in an obvious way). The small block SS isn't coded because there'south typically nothing unique nigh it. Fisher torso besides punches holes and runs electrical items (ability windows, power locks) in sure spots. In the mid 70's as these options became available, they'd exist indicated on the tag as well. In some cases, these punched holes hint at things (like TH400 kickdown holes, or Muncie speedometer cable holes)...
The trim tag is not a legal piece of data. It'south informative, but not definitive. In otherwords, a trim tag hinting at a SS 396 Camaro with a half dozen cylinder VIN number is not an SS. It's a half dozen cylinder Camaro - regardless of what the tag says. The VIN trumps the tag. What yous see is what yous get and that trumps the tag besides. Just it's squeamish to know what the tag is saying. Hopefully what you lot come across is agreeing with the tag itself. Y'all won't become arrested for removing or switching tags but you may wonder WHY the tag was switched, if it was. I have no idea why people would do that... it could be innocent or it could be for nefarious purposes.
The Tag is generally rivited onto the trunk, except in some years (1973 & 1974) where they only spiral information technology onto the car with canvas metallic screws.
A notation virtually paint. As we know, Fisher Body paints the auto. Generally, the regularly available color code will be indicated, but occasionally, you'll see "--" where a number should be. This means the car had SPECIAL PAINT. Information technology doesn't say WHAT paint was used - simply that the car isn't getting a stock offered colour. It could stand for anything. Sometimes (more often than not not on camaros) - a WA code will be stamped, and you can translate that WA code to a color. Or it might have the color lawmaking from another car line on it. By and large on the Camaro, special paint is represented as "--", and it'south generally indicating "black".... but not ever. You'll need to check the Build sheet (if bachelor) or check for trace show on the car as to the original colour. Otherwise, your guess is every bit good as mine.
The Corvette is totally congenital by Chevrolet. Information technology has a tag, just it'south not a Fisher Body tag. This besides explains why y'all will find complete assembly instructions in the Assembly Manual and Shop manual. All aspects of the Corvette are Chevrolets responsibleness.
Location on 1967 - 1969 Camaros is on firewall next to brake booster. From 1970 - 1981 it's facing upwards on the cowl panel as you open the hood, right nigh the windshield on the drivers side. 1982 - 1985 model location is nether the hood on the radiator cross back up. Mid 1984 models contain the body tag and a Service Parts Identification Label located in the center of the console cover). In 1986 the body tag is no longer used, replaced with just the Service Parts Identification Label (which is useless if you replace the console chapeau). The Service Parts ID Label contains VIN, selection codes, paint type, paint code, convertible elevation code and interior trim code.

Norwood built cowl tag decoding.
Read the tags from left to right, top to bottom. Additional detail may be hyperlinked and spans years. My individual yearly Camaro information also has a tag specific to the yr contained in in that location, as well as a wide amount of color/trim information specific to that year. Where OPTIONAL is mentioned, this data may or may not be present. ** For example, if the motorcar doesn't say Z27, it'southward 99.9% sure it'due south Not a SS car.

Model Clarification - Combination of Motorcar sectionalization, Series and trunk mode. (extracted fromVIN)
Breaks out every bit 1|24|87.
ane = Sectionalisation (chevrolet) |
23 = 6 cylinder Camaro (1970 - 1972)
24 = 8 cylinder Camaro (1970 - 1972)
FQ = Camaro Base level (1973 - 1978)
FS = Type LT (1973 - 1978)
FP = Camaro Base level (kickoff in 1979)
FS = Berlinetta (beginning in 1979)
| 87 = body style (2 door coupe)
Assembly Plant - identifies which assembly plant built the car
Assembly establish code designation changed in 1973 from 3 characters to one.
L (or LOS) = Van Nuys, N (or NOR) = Norwood
See to a higher place for additonal examples of assembly plants for other car lines.
Body Sequence Number - production serial number of the body, won't match the VIN sequence.
Trim Lawmaking - Indicates (interior) trim color and material.
Due to the broad variety of trim colors bachelor, and especially later 1973 in which diverse dashboard, rug & fabric combinations were offered.... it's best to select the year you wish to decode from the drib box below.
Paint Lawmaking - indicates the outside pigment color and vinyl top colour if and so equipped. A two part code indicates bottom and top colors respectively on a 2 tone pigment choice, or what color an optional stripe, convertible elevation or vinyl top was ordered. When a car has the same upper & lower code, it tin can be assumed the machine was a solid color.
Due to the wide multifariousness of colors available, and especially in later years in which color keyed wheels, dual or triple tone color schemes or stripes were used, it's all-time to select the model year car you want to decode from the drop box. In addition to the codes, I've added color chips where available.
Paint Type Code: L = Lacquer, E = Enamel, W = H2o
Starting in 1985 the paint types are:
DIS Lacquer - Dispersion Lacquer
SOL Lacquer - Solution Lacquer
BC CC - Base Coat/Clear Coat
Water - Enamel
Build Engagement - digit 1 & two identify month, third digit identifies week.
Month code: 01 = Jan, 02 = Feb, 03 = Mar, 04 = April, 05 = May, 06 = Jun, 07 = Jul, 08 = Aug, 09 = Sep, x = October, eleven = Nov, 12 = Dec
Week code: A = 1st, B = 2nd, C = third, D = 4th, East = fifth
Accessory codes (or optional information):
On Norwood cars, Z28 and SS (Z27) will be indicated here. In add-on to the "FS" on Type LT's, a "Due south" may be in this surface area to signify Type LT'south. In 1975 with the reintroduction of the Rally Sport, a Z85 volition be in this position. In 1979 that designation was shortened to "Z". If the auto was a standard sport coupe, this surface area would exist blank.
If the car is a Super Sport, the tag volition be stamped Z27. Next to this will be the engine RPO if it was a Big Cake. (LS3, L78)
If the auto was a Z28 the number side by side to the code is the stripe code. The stripe code corresponds with the year pigment code. Blank = no stripes. nineteen = black, ten or 11 = white.
Stripe code in 1973 was
Bare = Wasn't ordered with D88 stripes | YF8 = blackness stripes | ZR8 = white stripes
One word of circumspection.... the "reproduction" (or counterfeiting) market is at present making these tags for sale - stamped every bit the heir-apparent desires. Every bit such, extra scrutiny should be used in comparing the torso tag, VIN, any other documentation, and the actual auto, to look for oddities.
The other "need" for these tags is non just to fake Z28'due south or Super Sports, simply to restore a car, and then get a trim tag to friction match the restored car and try and phone call it "100% original". Not many people want to meticulously restore a lime green automobile with tan interior.
Batch codes - Very few people know how to decode these. I'll put more in here later. With the counterfeiting of trim tags, this is the last code which could be used to scrutinize the trim tag as existence direct up, or faked.
