Most CitroŽns built after 01 Jan. 1980 have a 4-digit number stamped in ink
somewhere on the body. From this, the so-called "ORGA" or "RP" number, one can
calculate the day of production of that vehicle. Apparently, CitroŽn
first introduced this number on 08 Nov. 1976, since that is the day that
corresponds to the ORGA number 0001. Starting from that date, this number was
incremented by 1 every day, whether the factory was operational on that day or
not. To calculate the day of production easier, I have included an
ORGA-number to production date converter at the bottom of this
2CV and Dyane - On top of the bulkhead, right hand side.
BX - It is printed in blue (?) ink on the A-post (in front of the
front door) on the driver's side just below the upper hinge, next to the sticker
that specifies the tyre pressures. CX - On the front of the left
hand side suspension turret, usually hidden by wiring. GSA - On
the right inner front wing (?). Xantia - On the bulkhead just in
front of the right -front- suspension sphere (quasi below the front window). At
that position one finds the color-code (a letter code) and, in smaller
characters above that, the ORGA number. XM - It is printed in
white ink on the A-post (in front of the front door) on the driver's side.
Information on where to find the ORGA number on other CitroŽn models is
not yet available.
In order to be able to use the converter below, you'll need a
Internet Explorer 3.0 or higher.Please enter only numbers in the ORGA or RP
number entry field. No checking of the input is done (yet).
