Yes, this is the first time I have seen # and @. They are not allowed in Australia.
The plate reads: #4pe@ce (for peace) ☮️
Cryptic, however a nice message.
First time ever I've seen the @ and # on a license plate. Agreed, @DaveCleghorn, that it says "For Peace" in a cryptic way...probably because the NC license plate FORPEACE or 4PEACE or anything similar wasn't available or allowed. Just asking, is anyone not for peace?
Like Mike Simon, I'm not familiar with their social media use other than the fact that in some instances using the @ as a prefix will automatically bring up a name in your contact list OR in the thread you are talking about. (apparently NOT here however!). As for the # or hashtag as they say, I must admit I'm ignorant on the social media use of that. My life doesn't seem to be missing much so it cannot be THAT important.
[FWIW in the computer world, I used to work for an Israeli company, and their main computer system in graphics used a highly modified version of an HP RTE OS real time operating system on an HP1000 series minicomputer. The prefix for getting the operating system's attention was the @. The Israeli engineers called it "streudel" since it resembled a pastry. Long before the # or number sign was called hashtag by today's generation, it was called octothorpe by telephone engineers; press the # on a phone and it generates a multifrequency tone of 941+1477 Hz]
