craigslist texting scam?

i just posted some ads and got a reply via text , the return # was only 5 digits and the message was kind of vague , is this a new scam for pay #s ?
thanks in advance

did a little more googling and yes it is a scam if you get a weird text form a 5 digit # dont answer it

Have seen adds with the phone # scambled like abc-def-ghij   222-333-4445 Or a combo of #'s and letters so guess it has been going on.

We have not gotten any yet. Thank goodness.

I've just recently started posting on CL. Good info. I appreciate it 

basic rule of craigslist is if something seems off don't bother responding, most likely it's a scam, at the very least it's probably someone who's going to waste your time and not a serious buyer anyways.
