Gt bike serial number.
If the bike frame was manufactured at the santa ana ca facility the first three or four digits of the serial number should be letters abbreviating the model or size of the frame such as xl xxl cr24 or something like that.
Vintage and older gt bikes may have serial numbers placed on other areas of the frame such as the seat stays next to the rear dropouts or the head badge.
This is not always the case and there will be some bikes that do not fit into this formula.

Okay fine so maybe there are a few bikes without serial numbers but this is rare and typical only on hand made bikes or really old bicycles.
