Who called from 2560000000

I just received a phone call and so did my boyfriend from the 256-000-0000 and a lady answered then said" oops wrong number". I was wondering if anybody has figured out exactly what is with it or if anybody has had charged from that number???

same thing here!!!   I live in the SE Michigan area with a prefix of 734 on my cell......got the call today at 5:09PM  .......i didn't answer the phone...... and she is damn lucky I didn't.

My wife received a call on her cell phone with the young lady saying wrong number then not 10 minutes later the same thing on my home phone....eerie.

Got a call today around 9 am.  The lady said she dialed a wrong number and hung up.  I am in Michigan and on a do-not-call list.

I got a call from the same young girl telling me it was a wrong number on my cell phone earlier this evening.  I didn't think anything of it until I got the call on my home number about 5 minutes later.  I tried asking her who she was trying to call and she again said it's the wrong number and immediately hung up.  I'm a little freaked out that everybody is getting this call.....are we going to have ridiculous charges on our phone bills?
