If the tag was to get separated from the rifle, does that number on the barrel give an indicator of the caliber?

Without taking the rifle to a gunsmith how does one verify that it is indeed a .308 versus 30.06?

Thanks for your time.

Did you buy this from the CMP of a private party?
If it came directly from the CMP it is most likely chambered for the NATO 7.62x51 (.308).
If you purchased it from a private party it may have already been modified.
The MANN barrel was designed to test ammunition and a commercial 308 round will not chamber properly without the head spacing being modified.
But if you bought it from the CMP the head spacing should not have been modified and should work fine with legitimate NATO 7.62x51 ammunition or Commercial 308 resized with a SMALL BASE case sizing die.
This thread may give you some insight.
