You will have to go to a jeweler or something to get it engraved. I handled the first batch getting engraved and I had to sort through the whole order and find the numbers, some people bought 2-3 of the same number, some people bought several different years/numbers, it was a real pain. So this time around I just ordered a bunch of blanks. Any jeweler could engrave it, or at the mall around here theres a place called "Things Remembered" and they sell personalized gifts and also do engraving.
