report a scam on craigslist

Yesterday I had posted an ad to Craigslist, I received a text from 505 886 5579 saying they were interested in the items I posted and asked me to send a code to verify I am real. This person’s email is [email protected]. I thought this new way to avoid the scam, then I gave the code to this person. After all I realize this is scam, this person may use my phone number to register a new account. I'm make report here, hope everyone be careful of this phone number and email.
