Serial Numbers
Serial numbers can be used to identify the year a particular model may have been produced from the 1979 model
year on.
Prior to 1979 it is NOT possible to identify a Peugeots year of production from its serial number. Regardless of
what you've read and where you've read it it simply isn't possible!!! The number of digits may indicate the decade
of production with 5 digits representing a 50's model, 6 for a 60's model and 7 for a 70's model. Peugeot
changed decal schemes very frequently. Changes in decals, along with component changes, make it easy to
narrow down a models year of production to within 2 or 3 years without a serial number. For bike produced prior
to 1979 decal schemes and component date codes are the preferred methods of narrowing down a production
year.
For bikes produced in the 50's, 60's and early seventies its more difficult to date them because Peugeot didn't
change decals or components often. Some models were identical in every way for a period of several years. For
those models it takes not only the serial number but a keen memory if you were the original owner or knew the
owner.
Some time around 1979-80 Peugeot labeled bikes with a small paper sticker. This sticker has the alphanumeric
model, size, possibly a color code and a model specific serial number. I say model specific because these models
also have a frame specific number. A frame specific number would have the following format: Y012 12345678.
At the time of this writing its not known what these numbers mean. Y012 may be the date code with '0' being the
year and '12' being the month the frame was built, not the bike. '012' may also be '0' for the year with the
second and third dgits being a frame material code. There are many frames with YX03 stickers and YX01 stickers
which may be for Carbolite 103 tubing and Reynolds 501 respectively. Although no definitive documentation has
been found/provided more than like;y the numbers represent the year and month of production.

| The following numbers are from a 1985 P18 mixte, As you can see there's a paper sticker and a stamped number. As noted earlier the stamped serial number is 8 digits. The sticker breaks down as: P18=model Click image Click Image T=handlebar type BU=unknown or burgundy 53=frame size in CM |
| The following numbers are from a known 1984 P8. Again, there's a paper sticker along with the stamped serial number. The breakdown is as follows: P8=model 60=frame size in CM Click image Click image 3393109=model serial number |
| The stamped serial matches the sequential number on the paper sticker. This is the only Peugeot II know of with this unique numbering. The breakdown is as follows: PH12=model Click image Click image 54=frame size in cm |
| Date Codes Component date codes are helpful in determining a models year. On occasion serial years. Date codes are simply stampings on various components which represent their date of manufacture. Codes vary by manufacturer. Older models may have NO codes while newer models have many. Codes can be found on cranks, hubs, rims, stems and other components. A good source for interpreting component date codes is the Vintage Trek website. VintageTrek |
