Maybe we are talking different things. I was thinking the number in the corner of the sticker. The date should be put on the sticker at the time the radio was certified as narrow. I know the picture is poor but if you can see the 131 in the corner that tells that the certification of it being narrow was done by me. Need any radios certified as narrow because I still have a bunch of stickers LOL
