(831) Area Code Business Phone Numbers
Get a real local number for Salinas, Monterey, Santa Cruz, and the rest of California's Central Coast. The 831 code was split off from 408 in 1998, and it still signals "we're from around here" to anyone picking up the phone.

The 831 area code was carved out of 408 in 1998, when the old South Bay code was running out of combinations. It covers Monterey, San Benito, and Santa Cruz counties, which means one three-digit prefix stretches from the UC Santa Cruz redwoods down through Pebble Beach and the Salinas lettuce fields to the quiet ranch roads around Hollister. Folks on the Central Coast know their code, and a caller ID that starts with 408 or 650 reads as "someone from over the hill."
Salinas and the surrounding valley are built on agriculture, with the region producing more than 70% of the country's leafy greens and earning the nickname "America's salad bowl."[1] That means the local business mix leans toward growers, packers, cooling houses, trucking yards, and the equipment and service shops that keep them running, plus a steady layer of restaurants, clinics, and real estate offices serving the people who work them. Tourism carries a lot of weight too, with the Monterey Bay Aquarium pulling close to two million visitors a year and anchoring hotel and tour-operator businesses up and down the coast.[2]
A local 831 number tells a customer in Watsonville or Seaside that you are nearby and that someone will actually pick up. Even if your team is spread between a shop in Salinas and a laptop in Santa Cruz, one 831 line can ring every one of them. That is the point of a cloud-based service like Tonet: the area code stays local even when the people do not sit in one building.

What You Get With an 831 Number From Tonet
Every feature is included on both plans. The difference is only how you pay for calls and texts.
Auto Attendant
Record a greeting that sends callers to sales, dispatch, or a specific person. Nest menus as deep as you need for a farm office that routes buyers one way and drivers another.
Call Recording
Toggle recording on any 831 line, incoming and outgoing. Keep orders, delivery notes, and service calls on file for the retention window you set, 90 days by default.
AI Transcription
Recorded calls are transcribed with speaker labels and a short summary. Search the text, jump to any word to play from there, and skim yesterday's calls instead of re-listening.
Business SMS
Send and receive texts from your 831 number for appointment reminders, delivery updates, or quick confirmations. Sending needs a one-time 10DLC carrier registration from the dashboard.
Mobile App
Same login on iOS and Android as the dashboard. A technician out at a Watsonville jobsite can take calls to the office line without handing out a personal cell.
Daily Billing
Plans start at $10 per user per month billed daily against a prepaid balance, numbers are $2.50 a month each, no contracts. Add a seasonal picker in May, drop them in November, and the charges stop the day you do.
Frequently Asked Questions
Can I get a real 831 number if my business is not in Salinas?
Yes. Pick 831 from the dashboard and the number works right away, whether you sit in Monterey, Austin, or Manila. It shows as a local Central Coast number on caller ID.
How much does an 831 number cost?
Each number is $2.50 per month. On top of that you need a user plan: Pay As You Go at $10 per user per month plus 1 cent a minute and 3 cents a text, or Unlimited at $15 per user per month for US calls and texts under a fair-use policy.
Can I port my existing 831 number over?
Yes, at no charge. Fill out the port form in the dashboard, sign it on screen, upload your current carrier bill, and track the status. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working the whole time.
Will one 831 number ring my whole team?
Yes. Put the number into a ring group and every member rings at once. Turn on Call Queue and callers wait with hold music if everyone is on another call. Nobody at the Salinas office needs to transfer manually.
Does an 831 number from Tonet work for banking 2FA or app sign-ups?
It is a VoIP number, so it usually does not work for banking-style verification codes, and it is case by case for other apps. Don't count on it for things like that. A US SIM is the dependable route for 2FA.
