Sooner or later, most of us end up asking: what is the cheapest way to get a business phone number? I asked the same thing not long ago, and the answers I found online were either vague or trying to sell me something. This guide is the opposite of that — straight talk, real numbers where they exist, and practical advice you can actually use today.
Whether you’re dealing with this right now or just planning ahead, it helps to know what’s normal, what’s overpriced, and what’s a flat-out bad idea. I’ve broken it all down below in plain English, no jargon and no fluff.
What is the Cheapest Way to Get a Business Phone Number: What You Need to Know
You need a business phone number that isn’t your personal cell — for professionalism, work-life boundaries, and credibility. The cheapest good option is free: Google Voice. But ‘cheapest’ and ‘best for you’ diverge as you grow, so here’s the honest breakdown from $0 upward.
Google Voice: $0, and genuinely good for solopreneurs. You get a real phone number (choose your area code) that rings your existing phone, with voicemail transcription, call screening, business hours routing, and texting — all through the app. Setup takes 10 minutes. The catches: one number per account, limited customer support, occasional porting quirks, and Google’s history of killing products makes some businesses nervous. For freelancers and brand-new businesses, though, it’s the obvious starting point. Worth reading next: Is Franchising a Good Way to Start a Business With No Experience.
Here’s What Really Matters
The $10–$20/month tier is where growing businesses land. OpenPhone ($15/user/month) is the modern favorite: unlimited calling/texting in the US and Canada, shared team inboxes, auto-attendant (‘press 1 for sales’), voicemail transcription, and integrations with HubSpot and Slack. Dialpad ($25/user) adds AI call transcription and analytics. Grasshopper ($14/month) is the old reliable for solopreneurs wanting a professional front. These services run entirely as apps — no hardware, works on the phones you own. For the official guidance, see Consumer Reports’ buying advice.
Carrier business lines ($30–$60/month per line from AT&T, Verizon, T-Mobile) make sense in exactly one scenario: you need a separate physical phone or your business depends on carrier features like priority data. For most small businesses they’re overpriced — you’re paying for a second device plan when an app would do. The exception: field businesses where employees need rugged work phones; then carrier lines with device financing make sense.
Practical Steps That Work
- Google Voice: $0 — real number, voicemail transcription, call screening; perfect for starting out.
- OpenPhone ($15/user/mo): team inboxes, auto-attendant, integrations — the growing-business pick.
- Dialpad ($25/user/mo): adds AI transcription and analytics.
- Carrier lines ($30–$60/mo): only worth it for separate physical/field phones.
- Local area codes convert better for local businesses; toll-free ($5–$15/mo) suits national ones.
- Port existing numbers (3–10 days); set professional voicemail day one; keep business/personal separate.
The Part Most People Miss
Don’t forget the toll-free question. An 800 number ($5–$15/month add-on from most VoIP providers, or free-ish via Google Voice alternatives) still signals ‘established business’ to many customers, especially 40+. For local businesses, a local area code number actually converts better — people trust local numbers and answer them. Match the number type to your customer psychology, not your ego.
Porting and professionalism notes: you can port an existing number into most of these services (takes 3–10 days; don’t cancel the old service first). Set up a professional voicemail greeting on day one — it’s shocking how many businesses skip this. And separate your number from your personal one even if you’re solo: the boundary protects your evenings, and the day you hire, the business number transfers cleanly instead of being tangled in your personal phone.

My recommendation ladder: just starting out → Google Voice (free, 10-minute setup). Growing, need team features or auto-attendant → OpenPhone ($15/mo). Need AI transcription/analytics → Dialpad. Physical phones for field crews → carrier lines. Revisit yearly — at 3+ employees, the per-user math deserves a fresh comparison.
Common Mistakes to Avoid
- Using your personal cell as the business number — no boundaries, no clean handoff when hiring.
- Paying $50/month for a carrier second line when a $0–$15 VoIP app does the job.
- Choosing a vanity/toll-free number for a local business where a local area code builds more trust.
- Cancelling the old service before porting completes — losing the number permanently.
Questions People Ask
Can I keep my existing number?
Yes — port it to Google Voice ($20 one-time) or any VoIP provider. Takes 3–10 days; keep old service active until porting completes.
Is Google Voice really free for business use?
Yes, the standard version is free. Google Workspace users get an upgraded Voice with more business features at $10/user/month.
What about WhatsApp Business?
Great free complement for messaging-heavy businesses, but it’s not a phone-number replacement — customers still expect to call a real number. Use both.
How do I keep business and personal finances separate?
Open a dedicated business checking account on day one — it’s free at most online banks — and run ALL business income and expenses through it. Pay yourself with regular transfers to your personal account instead of spending directly. This separation makes taxes dramatically easier, looks professional to clients, and is legally essential if you formed an LLC and want its liability protection to hold up.
When should a small business hire an accountant?
Get a one-time consultation ($200–$400) when you start earning real revenue, to set up your tax structure and estimated payments correctly. Hire ongoing help when tax season takes you more than a weekend, when you hire employees, or when revenue passes ~$75,000–$100,000. A good accountant typically saves more than they cost through deductions and penalty avoidance you wouldn’t find alone.
The Bottom Line
Start free with Google Voice — it handles solopreneur needs brilliantly. At $15/user/month, OpenPhone adds the team features growing businesses need. Skip carrier second lines unless you need physical work phones. Keep business and personal numbers separate from day one.
