Is there an age limit on wire in NEC?
There is no limit to the age of the wire, even old knob &amp; tube can be used to maintain historical accuracy. The one place I would modify this statement is on aluminum wire but code allows repair with the same type of device or material without upgrading. 
As far as your 12-3 if it has not been in the sun so the outer thermoplastic covering is good it can be used the same as a brand new roll of 12/3. Since you can read the listing information it is fine.
