The ratio code is usually two letters (sometimes 3, sometimes a number & 2 letters), and is found on the right-hand axle tube. The code will tell you what was originally installed in the housing, but nothing about any changes that might have been made since then.

You'd be better off checking the true ratio either manually, or by popping the cover and looking on the edge of the ring gear for four sets of numbers, two of which are tooth counts and two of which are date codes.
