Phone Number Prefixes and Carriers

Our California phone number lookup for the 818 area code analyzes the three-digit prefix to identify the initially assigned telecommunications company and rate center. This prefix code data may help to determine the U.S. carrier, California geographic region, and local calling area associated with the phone number.

Phone numbers follow the following structure under the North American Numbering Plan:

• NPA- area code (where the number was originally assigned)
• NXX - Central office code that locates the specific neighborhood and identifies the service provider
• XXXX - Subscriber number identifies the individual phone line within that local exchange

Understanding the area code can help you determine if a call is local to your area. However, keep in mind that due to mobile number portability and VoIP services, the caller may be anywhere in the United States, so it’s best to search for the most recent phone number details.

Prefixes by Company

Carrier names have been updated from their original FCC assignments to reflect current companies following mergers, acquisitions, and rebranding. Updates were determined using AI-assisted research and may not be accurate or reflect up to date changes. This data is provided without warranties of accuracy or completeness.
