Contact the concierge if you are a guest in an Atlanta hotel. The concierge will call a cab on your behalf and have it waiting at the door for you.
Call a local cab company; there are dozens in Atlanta. Tripsmarter.com provides a list of Atlanta cab companies and the contact information for each. Call one to request a cab. Provide the address of your location so that a driver can be dispatched to you.
Go outside and hail a cab yourself. Atlanta cabs are not as easy to hail as those in New York City, because there are not nearly as many on the streets. However, if you are at the airport, you can easily hail a cab outside baggage claim.
