    Caution;  Merge;  Workers Ahead! Avalanche 1.0 Disc - serial number - PLEASE HELP!

    I recently bought about half of a 2003 Avalanche 1.0 Disc (The same Blue/Silver frame here) including the frame, fork, and a couple other components. I fixed it up for my girlfriend to use. About 2 weeks after I finished fixing it, it was stolen out of my garage. I hadn't thought to record the serial #. Now I am learning the hard way that there is almost nothing you can do about a stolen bike without the serial number.

    As blind luck would have it , I took a couple of pictures during repair and one of them shows only the **LAST 4 DIGITS** of the serial number, eg 1234.

    A little reading has told me that these may be the only "unique" digits in the serial. Which is to say, a serial number organized as follows:

    [XX####] [1234]

    Where the [XX####] describes the manufacture location, build location, date of manufacture, etc... and the last 4 digits are the unique identifier.


    • Can anyone help me with trying to reconstruct the whole number, or at least get an idea of what it may look like?
    • Anyone have more insight about the serial numbers?
    • People willing to share all EXCEPT the last 4 digits on similar bikes?

    I badly need as much of this number as possible to file a proper police report and inform pawn shop owners, etc. what to look out for!

    Any help is greatly appreciated.


    FYI: I read this already:
    Also, I contacted GT, and they said due to being new owners, they do not have old records that might help.

    I had an '03 Avalanche 1.0 exactly like that. I just happen to have the bb shell from that frame sitting on my desk (I worked at the shop I bought it from, got to destroy the frame myself for warranty and keep the BB shell as a momento).

    Serial number is IGT3A11786
