"RE: Attn: New purchasers: Please share serial number"
I just checked and mine was made in Japan. (serial number 500XXXX) and I got it in late June 2012.when the D800 was released Nikon announced that the D800 would be made in Japan (Sendai factory) and assume that is still correct.Anyway for the purpose of the original poster I think all the above answers conclude that you cannot tell how old your D800 is by the serial number.
