513 was one of Ohio's original area codes from the 1947 split, back when the whole southwestern corner of the state shared a single prefix. These days it covers Cincinnati and the ring of suburbs around it, from Hamilton and Middletown down through Mason, Norwood, and Oxford. If you grew up in the area, 513 just reads as home.
The Cincinnati metro is home to about 2.31 million people, which makes it Ohio's largest and the nation's 30th largest metro area [1]. REDI Cincinnati tracked $819.7 million in capital investment across 51 economic development projects in the region in 2025, so there is real momentum behind the small businesses here [2]. Hamilton County alone counts roughly 26,600 business establishments [3].
When your contractor, salon, or law practice shows up on caller ID as a 513 number, people in Hyde Park or West Chester pick up. An 800 number says call center, a cell number says maybe a scam, but a 513 number says the shop around the corner. That is the whole reason to bother with a local line.
Cities Served by the 513 Area Code
The 513 covers Cincinnati and most of the surrounding Butler, Hamilton, and Warren County communities. If your customers are anywhere in the Queen City region, a 513 is the right number.
What You Get With a 513 Number From Tonet
Every feature is on both plans, so a Cincinnati plumber and a Mason startup pay for the same toolkit. The only difference is how you pay for usage.
Auto Attendant
Greet callers with your own recording and press-1 menu, then route them to a person, a group, voicemail, or an outside cell. Nest menus as deep as you need.
Call Recording
Flip recording on per number for incoming and outgoing calls. Recordings sit in the dashboard and come with a searchable AI transcript on each call.
AI Transcription
Recorded calls get speaker-labeled transcripts and a short factual summary with the outcome and next steps. Every voicemail is transcribed too, with the audio in your inbox.
Business SMS
Send and receive SMS and MMS from your 513 number, with the conversation shared across your team. Sending requires the one-time A2P 10DLC carrier registration, filed from the dashboard.
Mobile App
iOS and Android apps use the same login as the dashboard, so you can take 513 calls from the Banks or from a job site in Hamilton. Browser works too, no install needed.
Daily Billing
Plans run $10 or $15 per user per month, billed daily from a prepaid balance. Add a user mid-month, pay only for those days; remove one, the charge stops that day.
Frequently Asked Questions
Can I port my existing 513 number to Tonet?
Yes, porting in is free. Most ports complete in 7 to 10 business days, sometimes longer depending on your current carrier. Your number keeps working with your old provider until the switch, so no downtime.
What does a 513 number cost?
Numbers are $2.50 per month each. On top of that you pick a user plan: $10 per user per month on Pay As You Go (1 cent a minute, 3 cents a text), or $15 per user per month on Unlimited for US calls and texts.
Do I need to live in Cincinnati to get a 513 number?
No. You can be anywhere in the world. The number is picked by area code in the dashboard and works immediately, with no US address, company, or SIM card required.
Can I use my 513 number on a desk phone?
Yes. Tonet works with standard SIP phones from Yealink, Grandstream, Poly, Cisco, and Fanvil. You can also buy a pre-configured Yealink from Tonet shipped to a continental US address, with $100 of calling credit included.
Can a 513 number ring a whole team at once?
Yes. Set up a ring group and every member rings at the same time, or turn on Call Queue so callers wait with hold music until someone is free. If everyone is offline it drops to the group voicemail.
