610 as an Overlay of 215
Area code 610 is an overlay of area code 215, meaning the two codes share the exact same geographic territory in Eastern and southeastern Pennsylvania, including the Lehigh Valley, Delaware County, Chester County, Berks County, and portions of Montgomery and Northampton counties. When 610 was activated in January 8, 1994, all existing 215 phone numbers stayed unchanged. New phone lines in the region may now be assigned either 215 or 610, and ten-digit dialing is required for all local calls.

Browse 610 Numbers →- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 610 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. Contact us about a 610 number.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 610 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 610 number. If you already have a 610 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 Pennsylvania sometimes can’t accept inbound ports of 610 numbers due to 911 routing rules.
