The 678 code was introduced in 1998 as an overlay on top of 404 and 770, back when Atlanta was running out of numbers faster than anyone predicted. Today it blankets the same footprint alongside 470 and covers everything from downtown high-rises to the outer suburbs.

Metro Atlanta recently climbed back to the sixth-largest metro in the U.S., logging roughly 6.48 million residents [1]. The region is also home to a huge slice of the state's economy, generating about 60 percent of Georgia's $700 billion GDP and hosting the headquarters of Delta, Coca-Cola, Home Depot, and UPS [2].

A 678 number tells clients in Alpharetta, Sandy Springs, or Marietta that you're right down the road. Georgia has 1.4 million small businesses employing nearly 44 percent of the state's private workforce [3], so standing out in that crowd starts with looking local instead of like a random 800 number.
