Companies that hold curated inventories of specific area codes can sell you a 835 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 835 inventory.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 835 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 835 number. If you already have a 835 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 835 numbers due to 911 routing rules.

Is 835 a scam area code?
No. 835 is a legitimate, active area code for Eastern and southeastern Pennsylvania, including the Lehigh Valley, Delaware Valley, and areas west of Philadelphia — covering Lehigh, Berks, Delaware, Chester, Northampton, and portions of Montgomery County. Like any area code, scammers occasionally spoof 835 caller IDs, but the code itself is heavily used by real Pennsylvania businesses, government offices, and residents.
Why was the 835 area code created?
The 835 area code was created as an overlay because the supply of available telephone numbers in the existing 610 and 484 area codes was nearly exhausted. The Pennsylvania Public Utility Commission approved it on December 2, 2021, and numbers began being assigned on September 2, 2022.
Do I need to change how I dial if I have a 610 or 484 number?
No. The region has required 10-digit dialing since the 484 overlay was introduced in 1999. The addition of 835 requires no change in dialing habits — all local calls within and between the 610, 484, and 835 area codes continue to require 10 digits.
What counties does the 835 area code cover?
The 835 area code covers all or portions of Lehigh, Berks, Delaware, Chester, Northampton, and Montgomery counties in Pennsylvania, plus a small portion of New Castle County, Delaware.
