Shipping Order Number vs Sequence number vs VIN

Is the Shipping Order Number also called the sequence number? If I plug in my 1965 Dart 270 VIN into this well known decoder, it tells me the sequence number is 678096, which is part of the VIN. http://www.jonsteiger.com/www/CGI-BIN/62-65MoparVINDecoder.cgi
The IBM card tells me the shipping order number is 42934489 and it calls the VIN the serial number. It's confusing me.
Also, I can't find an online fender tag decoder for 1965, is there one around? Oops, nevermind, I found one here: 1965 Dodge Body Plate Data
Thanks,
Rick
