Is this a scam?

I got this text yesterday, along with a link (I did not/will not click it until USPS tells me its legit).

I haven't ordered anything, but I'm in some Facebook groups where we do gift exchanges and send each other things all the time, so it's possible that could be it.

I haven't had a chance to go into the post office yet. I did send an email to customer support, just waiting to hear back. I tried looking in my account on the USPS website, but I'm not seeing anything (not really sure where I would look or what to look for though)

I tried searching the number too, but didn't find anything. I know I have gotten legit texts like this from UPS before, but this is a first with USPS for me.
