(843) Area Code Business Phone Numbers
The 843 covers the Lowcountry coast, from North Charleston and Mount Pleasant down to Hilton Head and up to Myrtle Beach. It was carved out of 803 in 1998, and a 843 number still reads as homegrown Carolina coast to anyone who sees it on an incoming call.

Before 1998, every number east of Columbia dialed through 803. The 843 split off to cover the coast, and nearly thirty years later it still stretches from the barrier islands north to Horry County. People who grew up here recognize it the moment it rings.
North Charleston is the third-largest city in South Carolina and the industrial engine of the region. Boeing broke ground on a $1 billion expansion of its 787 Dreamliner complex here, with plans to add 1,000 jobs as production ramps to ten aircraft a month[1]. Roper St. Francis is building a new campus in the city that is projected to drive $2.5 billion in economic impact and create 3,600 jobs[2]. Between aerospace, healthcare, and the port, the small-business layer underneath is thick: contractors, trades, clinics, logistics shops, hospitality.
In a market this local, the number that shows up on caller ID matters. A 843 number tells a Mount Pleasant homeowner or a Summerville property manager that whoever is calling actually works in the area. Tonet gives you one in a few minutes, with no office visit and no US address requirement.

Frequently Asked Questions
How fast can I get a 843 number?
Minutes. Sign up at dashboard.tonet.ai/signup, add a card, make the $15 minimum deposit, and pick a 843 number by searching in the dashboard. Your phone system builds itself within seconds and you can place a call from the browser right away.
Can I port my existing 843 number from another provider?
Yes, and it costs nothing. The port form is signed on screen in the dashboard, with your current bill uploaded as proof. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working on the old service until the switch, no downtime.
Does Tonet charge extra for a 843 number versus any other area code?
No. Any US local number is $2.50 per month, whether that is 843 for Charleston, 212 for Manhattan, or anywhere in between. Pick as many as you want.
Will a 843 number work for banking verification codes?
A Tonet number is a VoIP number, and VoIP numbers usually do not work for banking-style two-factor codes. For other apps it is case by case. If you need a reliable number for 2FA, a US SIM is the dependable route.
Can one 843 number ring my whole team?
Yes. Put the number on a ring group and every member rings at once, on the browser, mobile app, or desk phone. Turn on Call Queue and callers wait with hold music until someone is free. If everyone is offline, the call drops to the group voicemail.
