Just got the same text. I agree it must be a scam. It's from an Arizona area code and I'm in Phila.

More interesting:
Myself and two co-workers all received this text within the last 12 hours. Three numbers that are in no way similar on three different carriers (T-Mo, Verizon, AT&T). One person did not, but his cell phone number is not listed in our system.
