904 as an Overlay of 305
Area code 904 is an overlay of area code 305, meaning the two codes share the exact same geographic territory in First Coast (northeast Florida), centered on the Jacksonville metropolitan area including Duval, St. Johns, Nassau, Baker, and Clay counties. When 904 was activated in July 11, 1965, all existing 305 phone numbers stayed unchanged. New phone lines in the region may now be assigned either 305 or 904, and ten-digit dialing is required for all local calls.

Browse 904 Numbers →There are three ways to get a phone number with the 904 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 904 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Browse our 904 inventory.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 904 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 904 number. If you already have a 904 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Florida sometimes can’t accept inbound ports of 904 numbers due to 911 routing rules.
