Mopar Broadcast Sheet by VIN — Decode the Fender Tag

A Mopar broadcast sheet is the paper production document Chrysler generated for each Dodge, Plymouth, or Chrysler vehicle as it was assembled. It lists the model, engine and transmission, paint and trim, and the full set of sales codes for every factory option. Because it was tucked inside the car during assembly, surviving broadcast sheets are prized by Mopar collectors. When the paper sheet is gone, the metal fender tag carries a condensed version of the same build data.

The Mopar fender tag is a stamped metal plate on the driver's-side inner fender or radiator support. It encodes the vehicle in rows of sales codes: the paint code, trim code, engine and transmission codes, the SO (schedule order) number, the build date, and option sales codes. Read it from the bottom row up, decoding each sales code against a Chrysler reference for that model year. The VIN confirms the year, plant, and body before you start, since Chrysler reused some codes across years.

Sales codes are Chrysler's short alphanumeric codes for factory options, colors, and equipment, the Mopar equivalent of GM's RPO codes. They appear on the fender tag and broadcast sheet, covering everything from the engine and axle to interior color and individual option packages. Decoding the sales codes for a given model year reveals exactly how the Dodge, Plymouth, or Chrysler was equipped at the factory, in more detail than the original window sticker.

SO stands for Schedule Order, sometimes called the scheduling or order number. It is the production order Chrysler assigned to the vehicle, appearing on both the fender tag and the broadcast sheet. The SO number ties the fender tag to the broadcast sheet and the rest of the build paperwork, so collectors use it to confirm that a car's tag, sheet, and VIN all belong together rather than having been mixed and matched.

During assembly Chrysler workers often tucked the paper broadcast sheet inside the car, where it sometimes survives for decades. Common spots include under the rear seat, behind or beneath the front seats, above the headliner, behind door panels, on top of the gas tank, and inside the springs of the seat frame. Survival is never guaranteed, and many were thrown away, so when no paper sheet turns up, the fender tag is the primary on-the-car build source.

The classic Dodge Charger and Challenger are among the most documented Mopars. Enter the VIN to confirm the year, plant, and body, then decode the fender tag for paint, trim, engine, transmission, SO number, and sales codes. If the original broadcast sheet survives inside the car, it confirms the same build in full. For a high-value Hemi or R/T car, collectors cross-check the fender tag, the VIN-stamped engine and transmission, and any surviving broadcast sheet to confirm a genuine numbers-matching example.
