Oakland 510 Area Code Transition: What You Need to Know

Mark Speer

The Oakland area is changing its phone numbering system to accommodate the growing demand for phone numbers. Here’s everything you need to know about the addition of the new area code, 341, and how it affects residents.

Oakland’s New Area Code Overlay

Oakland is introducing a new area code, 341, to supplement the existing 510 area code. This overlay is necessary to ensure a continuous supply of phone numbers for residents and businesses in the area.

Impacted Cities in Alameda and Contra Costa Counties

The 510 area code serves several cities across Alameda and Contra Costa counties, including Alameda, Albany, Berkeley, Emeryville, and more. Residents in these areas will be affected by the transition to the new area code.

Changes for 510 Area Code Users

If you currently have a 510 phone number, there are important changes to note:

1. New Dialing Procedure
You will need to adjust how you dial local phone numbers. Instead of seven digits, you’ll now dial the area code followed by the telephone number or 1 + area code + telephone number for all local calls, regardless of whether you’re dialing a 510 or 341 number.

2. Update Automated Services
Ensure that any equipment programmed to dial 7 digits is updated to reflect the new dialing procedure. This includes various systems such as life safety devices, medical monitors, PBXs, and more.

Key Dates to Remember

– December 15, 2018: Begin using the new dialing procedure (1 + area code + telephone number).
– June 22, 2019: Mandatory use of the new dialing procedure for all local calls.
– July 22, 2019: New lines or services may be assigned numbers from the new 341 area code.

Important Reminders

– Your phone number will remain the same; only the dialing procedure for local calls will change.
– The cost of calls will not be affected, and you’ll still be making local calls within the area.

Stay informed about the changes to Oakland’s area code system to avoid any disruptions in your phone services. By following the new dialing procedures and updating your automated services, you can seamlessly adapt to the transition and continue to stay connected in the Oakland area.
