(854) Area Code Business Phone Numbers
The 854 code went live in October 2015 as an overlay on top of 843, after the state regulator saw 843 running out of prefixes [1]. It covers the same coastal strip, from North Charleston down to Hilton Head and up to Myrtle Beach, so a 854 number reads as local anywhere along the coast.

Before 854, the whole coast of South Carolina ran on a single area code, 843, dating back to the 1998 split from 803 [1]. By the time 854 arrived in 2015, ten-digit dialing had already become the norm across the region, which is why nobody really thinks of 854 as the "new" code anymore. It just means a number was issued recently.
North Charleston is the third largest city in South Carolina and sits in the middle of a working economy, aerospace at Boeing, automotive, defense, bioscience and a growing tech scene [2]. Cantey Tech, headquartered in North Charleston, made the 2026 Inc. 5000 list of fastest-growing private companies in the country, one of 56 South Carolina firms on it that year [2]. The small business picture matches: contractors, logistics shops, hospitality, marine services, medical offices.
If you run a small business along the coast, a local number still carries weight. A 843 or 854 on the caller ID tells someone in Mount Pleasant or Summerville that you are actually here, not a call center two states away. Tonet gives you a 854 number in the dashboard the moment you need one, and you can swap in a 843 later if you want both codes on the account.
Cities Served by the 854 Area Code
The 854 overlay sits on top of 843 and covers 17 coastal counties, so a 854 number dials and rings as a local call across the whole Lowcountry and up through the Grand Strand.
Features Built for Coastal South Carolina Businesses
Every Tonet plan includes the same features. The difference between the $10 and $15 per user plans is only how usage gets paid, not what the phone system can do.
Auto Attendant
Record a greeting, map keys 1 through 9 to a person, a team, voicemail or an outside number. Useful when a marina or a dental office has one number and three places a call could go.
Call Recording
Toggle recording on per number, incoming and outgoing. A contractor can keep the quote conversation, a property manager can keep the tenant call, and both can search the text later.
AI Transcription
Recorded calls come back as a searchable transcript with speaker labels and a short summary. Voicemails are transcribed too and arrive by email with the audio attached.
Business SMS
Send and receive texts from your 854 number, with pictures and PDFs. Receiving works right away. Sending needs the one-time 10DLC carrier registration filed from the dashboard.
Mobile App
Same login as the dashboard on iOS and Android, so a crew in Goose Creek and the office in North Charleston answer the same number from wherever they are.
Daily Billing
$10 per user per month billed by the day. Add a seasonal hire in May, pay those days. Let them go in September, the charge stops that day. No contract, no seat minimum.
Frequently Asked Questions
Is 854 a real local number or does it feel like a cell code to people here?
It is a real local area code for coastal South Carolina, approved by the state's Public Service Commission and in service since October 2015. Because 854 overlays 843, anyone used to the Lowcountry sees it as the newer local code, not a long-distance or mobile code.
Can I get a 843 number instead, or along with a 854?
Yes. Both codes are available in the Tonet dashboard, picked by area code when you buy. Numbers are $2.50 per number per month, so running one of each on the same account is common for businesses that have been here through both eras.
What does it cost to get started with a Tonet 854 number?
Plans start at $10 per user per month billed daily, with no contract. Numbers are $2.50 each per month. The minimum top-up is $15 to get started, which lasts about 30 days for one user on Pay As You Go.
Can I port my existing 854 or 843 number to Tonet?
Yes, porting in costs nothing. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier, and your number keeps working with your current provider until the switch, so there is no downtime.
Do I have to dial all ten digits in the 854 and 843 region?
Yes. Ten-digit dialing became mandatory in September 2015, right before 854 went live, and it has been that way ever since. Tonet handles the dialing format automatically in the browser and the app.
