The VIN and the build date on the cowl tag match up very well for the 01D build week body number should be somewhere near 784xxx. The car should have been shipped around January 21 (actually a bit later like 1/23) not February 21st. I suspect you have a Typo on you NCRS document, wouldn't be the first one. Whats the full info on the body tag. Zone office delivery can mean all kinds of things, a special order car for a GM exec, something for a national car show, or a demonstrator.
