I have maintained a website about telephone numbering for 18 years. North American (USA, Canada, etc.) area code 877 is not linked to a specific geographic area, rather it is one of the area codes reserved for toll-free calls in which the calling party is not charged.Instead, the telephone carrier charges the cost of the call to the called party.78 is one of the codes used in Atlanta, Georgia.   678 is a telephone area code assigned to metropolitan Atlanta,  Georgia and its suburbs and exurbs. This area code was â¦ first  assigned to customers signing up for new telephone service on  January 15, 1998.
