see this thread:
Need a part number...
apparently the part# is
Part # is 79621-S3Y-941, or 79621-S3Y-A41
but I dont see anywhere where you can order it.
Options I can see is that you can try to find someone with a broken bezel to sell you the sticker, or buy another bezel. I saw someone selling a bezel in the for sale section for around $45
