What Is an 408 Area Code?
The 408 area code was established in 1959 as a split from the original 415 area code, which covered much of Northern California. It primarily serves the Santa Clara County, encompassing major cities such as San Jose, Cupertino, and Sunnyvale. As the region has grown, especially due to the influence of the tech industry, the 408 area code became synonymous with Silicon Valley.
The 408 area code is now one of the most recognizable codes in the United States, associated with technology giants like Apple, Google, and Facebook, all of which have offices or headquarters within its boundaries. Due to the rapid growth in population and business activity, the area code has expanded to include an overlay, 669, introduced in 2012 to provide more phone numbers to meet demand.

How Does a 408 Area Code Phone Number Work?
A 408 area code phone number works like any other North American phone number, following the standard format used in the North American Numbering Plan (NANP). The format includes:
- A three-digit area code (e.g., 408)
- A three-digit central office code (NXX)
- A four-digit line number (XXXX)
For example, a full phone number would look like: 408-555-1234.

How to Dial a 408 Phone Number?
Dialing a 408 phone number follows the standard procedure used throughout the North American Numbering Plan, whether you’re making local, national, or international calls.
Initiate with the International Access Code (For International Calls)
If you’re dialing from outside the United States or Canada, start by entering your country’s international access code (for example, 011 from most countries).
Enter the Country Code
Next, enter the country code for the United States, which is 1.
Include the Area Code
Once the country code has been dialed, enter the 408 area code.
Dial the Remaining Digits
Finally, input the seven-digit phone number associated with the 408 area code. For example, if the number is 555-1234, your full dialing sequence would be 1-408-555-1234 for international calls or 408-555-1234 for local and national calls.
Are Area Code 408 and 669 Overlay Codes the Same?
Yes, the 408 area code and 669 overlay code serve the same geographical area in Santa Clara County, including Silicon Valley. The 669 area code was introduced in 2012 as an overlay to meet the increasing demand for phone numbers in the region.
The key differences between the two codes are:
- 408: Established in 1959, it’s the original area code for the region.
- 669: Introduced in 2012, it’s the newer overlay code used when 408 numbers are no longer available.
Since both codes serve the same area, residents and businesses might receive either a 408 or 669 area code when requesting a new number.

Tips for Safety

How to Verify the Legitimacy of a 408 Number?
If you’re unsure about the legitimacy of a 408 number, here are a few steps you can take:
1. Check Voicemail: Listen carefully to any messages left. Scammers often leave vague or threatening messages, while legitimate businesses provide clear information.
2. Reverse Number Search: Use a reverse phone lookup tool to check the identity of the caller.
3. Consult Toll-Free Directories: Some companies have directories that list official contact numbers, including those with local area codes like 408.
4. Utilize User Databases: User-driven databases can provide information about whether others have reported a particular number as suspicious.
Countries and Territories Providing 408 Area Codes
The 408 area code is part of the North American Numbering Plan (NANP) and is used exclusively in the United States, specifically in California’s Santa Clara County and Silicon Valley. It does not extend to any other countries or territories outside the U.S.
