I have had the same cell phone number for a long time. I have always escaped telemarketers calling my cell phone because I am very careful to keep the number private (I don’t put it on forms and such).
Recently, however, things have changed. I have been getting calls various numbers (one of them: (206) 496-0957). It’s my habit not to answer any calls from numbers I don’t recognize but I accidentally answered a call from this number one time. It was for some political survey. Unfortunately, by answering the call, I proved to them that my number was a working number.
The 206 area code is for the Seattle, Washington area.
