The 310 split off from the original 213 in 1991 to give the Westside and South Bay their own numbering space. It got so tight that in 2006 the 424 overlay was layered on top, the first overlay California ever did [1]. If your number still starts with 310, you're holding onto a piece of coastal LA that new businesses can't get as easily anymore.
Los Angeles County is home to about 296,746 small businesses, the largest concentration in the state [2]. The 310 slice of that map runs from Malibu down to Torrance, and it's a mix of entertainment agencies, tech firms, restaurants, and trades who work up and down the coast. A 310 number tells locals you're one of them, not a call center somewhere else.
The labor force in LA County sits around 5.1 million people [3], and plenty of them screen unknown area codes. Answering with a familiar 310 gets more calls picked up, more voicemails returned, and more appointments booked. That matters whether you're a Culver City accountant or a Redondo Beach contractor chasing referrals.

Frequently Asked Questions
Can I still get a brand new 310 number?
Yes, though supply is tighter than it used to be. The 424 overlay was added in 2006 because 310 numbers were running out, so availability varies by prefix. We check inventory in real time when you sign up.
Do I have to dial ten digits inside the 310?
Yes, ever since the 424 overlay went live in 2006, every call inside this region has been ten-digit dialing. Your phone system handles it automatically.
What if my business isn't based in the 310 zone?
You can still get a 310 number. Businesses in the Valley, Long Beach, or even out of state pick 310 numbers because they work with clients on the Westside and want the call answered.
Can I move my existing 310 number to Tonet?
Yes. Porting your number over is free, takes a few business days, and you keep the number you've been giving out for years. Nothing changes for your callers.
How much does a 310 business line cost?
Plans start at $10 per user per month, billed daily. Extra numbers are $2.50/month each. There's no contract, so you can add or drop lines as your team changes.
