At present, there is no such area code as 6 14 for domestic and international long-distance calls.
If you receive a call starting with "6 14", there are several possibilities: 1. This is a call from other places; 2. This was dialed by a mobile phone somewhere; 3. This is a local call; 4. This is part of the beginning of the special service number; 5. This call was made through some kind of Internet phone. 6. This is a kind of telecommunication equipment that can modify and hide the real number (also called "arbitrary number display" software); 7. Are you misreading the caller ID number or is there something wrong with the device display?
