How to Get a Business Phone Number (And What to Do When It Rings)
Getting a dedicated business phone number is one of the fastest wins available to any small business. It takes your personal cell out of your marketing materials, signals professionalism to every caller, and gives you a clean line between work and personal life.
The process itself is simple. What's less obvious is what happens after you have the number — and whether anyone will actually answer it.
Here's the full picture.
Why You Need a Separate Phone Number for Your Business
Before we get to the how, a quick case for the why.
Using your personal cell as your business number creates three problems:
Privacy. Once your personal number is on your website, Google Business Profile, and Yelp listing, it's public forever. Customers, vendors, and spam callers have your personal cell. That doesn't go away.
Credibility. When a customer calls a business and reaches a voicemail that says "Hi, you've reached Mike" with no business name, they're not sure they dialed the right number. A dedicated business number can greet callers with your business name from the first ring.
Portability. If you ever hire a receptionist, add a team member, or switch phone systems, a dedicated business number stays with the business. Your personal number doesn't.
If you're currently using your personal cell for business, swapping that out is one of the highest-ROI changes you can make in an afternoon.
Your Five Main Options
1. Keep using your personal cell (not recommended)
Free, but all the downsides above. Skip this one.
2. Google Voice — Free or $10–$30/mo
Google Voice gives you a dedicated local number that rings your personal phone. The free personal version works, but it's limited and not officially supported for business use. Google Voice for Business requires a Google Workspace subscription ($6–$10/month) plus the Voice Standard add-on ($10/month per user) — so roughly $16–$20/month for one person.
What you get: a separate number, call forwarding, voicemail with basic transcription, and SMS.
What you don't get: someone to answer those calls. Google Voice rings your phone. If you don't pick up, it goes to voicemail. If you're on a job, asleep, or in a meeting, callers hit voicemail — and most of them won't leave one.

3. VoIP provider — $20–$50/mo
Services like RingCentral, Nextiva, and Grasshopper give you a business number with more features: voicemail, auto-attendant menus ("Press 1 for sales, press 2 for support"), call routing, and team extensions.
These are good options for businesses with multiple staff members who need to share calls. For a solo operator or small team, the features often exceed what you need, and the setup is more involved.
4. Carrier business line — $20–$60/mo
AT&T, Verizon, T-Mobile, and similar carriers offer dedicated business phone lines. These are physical SIM-based lines with a local number. They're reliable and fully supported — but they're also the most expensive option, often require contracts, and still don't answer calls for you.
5. Ringzy — From $39/mo
Ringzy provisions a dedicated local business number instantly — same as a VoIP provider — but the number comes with an AI that answers every call in under 2 seconds, 24/7. When someone calls your Ringzy number:
- The AI picks up immediately with your custom greeting
- It answers questions using information you configure (services, hours, pricing, FAQs)
- It books appointments directly into your Google Calendar
- It sends you a full transcript and summary after every call
No voicemail. No missed calls. No manual follow-up.

The Question Most Guides Skip: Who Answers?
Here's what every "how to get a business phone number" article leaves out: a number is only as useful as who picks it up.
Google Voice, VoIP services, and carrier lines all solve the "separate number" problem. None of them solve the "someone needs to answer this" problem. You still have to pick up every call yourself — which means every call you miss goes to voicemail.
For small service businesses — plumbers, HVAC contractors, electricians, dental offices, law firms — a missed call isn't a minor inconvenience. It's a booked job that goes to a competitor, or a new patient who calls the next dentist on the list.
The average small business misses 62% of inbound calls. Most of those go to voicemail. Most voicemails don't get returned the same day. By the time you call back, the caller has already moved on.
A dedicated number solves half the problem. Answering it solves the other half.

Common Questions
Can I get a free business phone number?
Google Voice (personal) is free and gives you a local number. If you plan to answer all calls yourself and don't need advanced features, it's a reasonable starting point. The limitation is that it's a forwarding number — it still rings your personal phone, and if you don't answer, it goes to voicemail.
Can I use my existing phone number?
If you already have a business number you've given to clients, number porting is an option with most providers — they move your existing number to their system. Ringzy currently provisions new numbers; porting is on the roadmap. In the meantime, many businesses set up call forwarding from their old number to the new Ringzy number during the transition.
Do I need a toll-free number?
Almost certainly not. Local numbers perform better for small businesses — callers recognize them and are more likely to pick up when you call back. Toll-free numbers (800, 888, etc.) are associated with large corporations and call centers. Unless you serve a truly national audience, a local number is the better choice.
What if someone already has my preferred number?
Number availability depends on area code. In most markets, Ringzy can find a local number quickly. If a specific number matters to you, check availability during signup.
Getting a business phone number is a one-afternoon task. The bigger question is making sure that number actually works for your business — answering calls, booking appointments, and keeping you informed — even when you can't pick up.
