This is Square (the new equivalent of a cash register) sending you a copy of a receipt. In order for it to do this, you would have to have provided your phone number. This is totally legitimate.
I got a text message on my cell from this #. It said "View your receipt from Lunchbox Deli:" followed by a URL link to squareup.com. I didn't take the bait. I wonder if it's a scam, especially since I've never been to a Lunchbox Deli?

Unless you made the call, to a number you verified as real & correct, there is no such thing as a legitimate call. As caller ID is easily spoofed (faked) you can never assume your caller is who they say they are.
