Area code 408 · San Jose, California

Get a 408 phone number for your business

408 covers the southern end of San Francisco Bay: San Jose, Santa Clara, Sunnyvale and Cupertino, then Milpitas, Campbell, Saratoga and Los Gatos, and south down the valley through Morgan Hill to Gilroy. It is a South Bay code rather than a Bay Area one, and it takes in only part of Silicon Valley. We provision numbers on a network we own, which is why one costs $1.00 a month and is not tied to a contract.

Palo Alto is not 408

408 does not run the length of Santa Clara County. Palo Alto, Mountain View and Los Altos are in the county but dial 650, so the northern strip of Silicon Valley falls outside 408 entirely. Fremont, up the I-880 corridor from Milpitas, is 510, and Santa Cruz over the hill is 831. What does share 408's exact ground is 669, which is why local calls here are dialled with ten digits.

What the 408 part actually is

A North American number has four parts. The area code is the second, and it is the one that tells a caller roughly where you are before they have spoken to anyone.

+1
Country code North American Numbering Plan
408
Area code Called the NPA in carrier systems
555
Exchange The NXX, a block within the area code
0147
Line number The individual line on that block
The example uses the 555-0100 block, which is reserved for fiction, so it does not ring anyone.

How to get a 408 number

  1. Tell us how many you need

    Give us the area code and a quantity. We search live inventory and come back with what is actually available, including any repeating or sequential patterns worth having.

  2. Point it wherever you want

    Route it to a seat, a ring group, an auto attendant, or straight down a SIP trunk into a PBX you already own. A number is not welded to one product on our network.

  3. Register the 911 address

    Every number needs a validated street address so an emergency call reaches the right dispatcher. That is a legal requirement rather than an upsell, and it takes about a minute in the portal.

Already have a 408 number?

Bring it. Porting a local number in is $5.00 once and the number itself does not change. Numbers port out again just as freely if you ever leave, which is worth saying because not every carrier makes that straightforward.

  1. You sign the LOA

    A letter of authorization proves the number is yours to move. We prepare it and send it over; you check the details and sign.

  2. We request the port

    The request goes to your current carrier with a copy of your most recent bill, which is what they match the account details against.

  3. They confirm a date

    The losing carrier accepts the request and returns a firm order commitment date. If they reject it, it is almost always a mismatched address or account number, and we fix it and resubmit.

  4. The number cuts over

    On the agreed date the number starts ringing on our network. Your old service stays live until that moment, so there is no window where calls go nowhere.

Questions about 408 numbers

Can I get a 408 phone number?
Yes. We source local numbers in every US area code, and 408 is $1.00 per number per month with no contract. You choose the number, we provision it, and it is on your account without a wait in most cases.
Where does area code 408 cover?
The footprint lies inside Santa Clara County, from Milpitas at the northern edge of the code down the valley to Gilroy at the far southern end. Pacific time applies throughout, and daylight saving is observed.
Do I need an office in California to use a 408 number?
No. A 408 number works from anywhere, and your team can be remote or spread across several states. What the number buys you is a local presence for the people calling you, which matters because a lot of people will not pick up an unfamiliar out-of-state number.
Is a 669 number as local as a 408 number?
Yes. 669 sits on exactly the same ground as 408, so both are local numbers for San Jose and the rest of the South Bay, and both are dialled as ten digits. Coverage and rate centres are identical; only the digits differ. Which of the two a given line carries is decided by the numbering plan, not by where the business sits.
Can I move my existing 408 number over?
Yes. Porting a local number in is $5.00 once and the number does not change. We prepare the paperwork and coordinate with your current carrier, and your existing service stays live right up to the agreed cutover.
What does a 408 number cost in total?
The number is $1.00 per month. If you also need a phone system to answer it on, seats start at $19.95 per user per month with every feature included at every tier. If you already run a PBX, point a SIP trunk at the number instead and pay per minute.
