info screen shows different receiver #

[NOTSO]

I have a 7200 that has a dealer locked rom 3 card and I am able to view programs but not the guide, I have noticed the reciever ID on the back of the receiver and the number provided me with the box keys is different from the receiver number that shows on the info screen.
My question is which is correct, I have a magic card that I want to test with but have been having troubles and think this might be the problem, I don't want to loop the card trying to get the ird number and box keys off it and the dealer dissappeared after the rom 3 plastic got hit last week... anyway any info would be appreciated.
Basically is the receiver number in the info screen correct? always?

The one on the screen is the correct one...........the box may not be original or the receiver may have been cloned to another, don't matter really, use the one on the screen.
