404 area code
Atlanta and nearby portions of the metropolitan area.
404 is associated with Atlanta's core. Overlay codes such as 470, 678 and 943 span a wider metropolitan arrangement that also includes 770. A 404 number does not describe the entire Atlanta region, and the prefix cannot establish whether an address is inside a particular service radius.

Questions about 404
Is 470 outside Atlanta because it is not 404?
No. 470 is part of Atlanta's overlay arrangement. It can serve customers in the Atlanta region, including places associated with 404 and 770.
Is a 404 call safe to answer?
The 404 prefix identifies a numbering region, not a caller's identity or trustworthiness. Verify an unexpected request by contacting the organization through a number you already know.
Can I get a 404 business number?
Search the available numbers in VeraDial. Inventory changes, so a 404 number is not guaranteed. You can also keep your current carrier number and forward voice calls to a VeraDial line; existing texts stay with your carrier.
