Identical situation, same phone number. Seeking a Craigslist ad for the iPhone 6 at $650. Reported the incident to PayPal, and my co-worker is trying to gather more information on the number.
Got a text message reply to a Craigslist ad wanting me to send a valuable item out of state asking me to accept payment via paypal, but the person refused to fund my account before I shipped the item. When I started asking questions, he balked.
Same thing just happened to me with a CL post, if this number contacts you just ignore them or tell them you're not selling without cash in hand payment.
They said they needed me to ship it and they'd add $200.00 extra for my time to ship it.
Always be wary of anyone offering a too good to be true offer or trying to pay in any other way than cash for things on craigslist.
