Area codes
US area codes, state by state
A local area code tells customers you're nearby. Pick a state for its area codes, the time zones they cover, and which codes overlay each other, then choose a local business number on Onyx Phone in the code your customers already know.

Choosing an area code for your business
- Match where your customers are. A number in their area code looks local on caller ID, and customers recognize it as nearby.
- Overlays are the same place. When a region runs out of numbers, a new code is added on top of the old one. Numbers in either code ring the same area, and everyone there dials ten digits.
- Keep the number you have. If customers already know your number, move it to Onyx Phone for free instead of starting over.
- One business, several areas. Your plan includes one number for each user, and more lines are $5 a month, so a business serving two cities can have a local number in each. See how lines work.
Getting started
- Create a login and pick a plan. Checkout saves a card for the 7-day free trial, and nothing is charged until it ends.
- Confirm your business and its 911 address, and get a local number on the spot. Bringing your own number? You answer on a temporary one while it moves over, for free.
- Choose where calls ring, write what callers hear, invite your team, and register for texting. Then answer in the browser, the iPhone and Android apps, or a desk phone. How it works has the details.
