In all cases of long distance, 1 plus the area code is used.  In small areas where local only is involved you usually only dial 7 digits.  In metro areas with multiple area codes, you use 10 digit dialing.  Some places you use 10 digit dialing or 1 + area code, depends on the phone company.    I've seen this happen on the east coast.
