How do I get a business phone number for my new business?

The best option for most new businesses is a VoIP business phone system that gives you a dedicated business number separate from any personal cell phone. Phonewire's cloud-hosted VoIP starts at $25/user/month and includes an auto-attendant, voicemail to email, business texting, and a mobile app so you can make and receive business calls on your existing cell without giving out your personal number. For the smallest solo businesses, a second-number app like Google Voice is a lower-cost starting point, though it doesn't scale well to a team.

Should a new small business use a personal cell phone or get a business phone number?

Using a personal cell as your business number works initially for solo operations but creates problems as you grow: clients have your personal number permanently, calls can't route to employees, there's no auto-attendant or call queue, and personal and work calls share the same device. Starting with a dedicated business phone number from day one avoids a painful number change later and gives you the infrastructure for professional call handling from the start.

What is the difference between a landline and VoIP for a new business?

A traditional copper landline transmits calls over physical copper wire from the phone company — these are being retired by AT&T through 2029 and are not recommended for new businesses. VoIP (Voice over Internet Protocol) delivers a business phone number over your internet connection with far more features: auto-attendant, voicemail to email, call routing, mobile app, business texting, and easy scalability. VoIP is what 'landline for business' now means in practice.

Can I use my existing cell phone as my business phone with VoIP?

Yes. Phonewire's Linkus UC app runs on your existing iPhone or Android and gives you a business extension on your current device. Business calls come in on the app with your business number showing as caller ID. Personal calls come in on your regular number. You don't need a second device. When you call clients from the app, they see the business number, not your personal cell.

How much does a business phone number cost for a new small business?

Phonewire's cloud-hosted VoIP for a small business runs $25 per user per month with no hardware purchase required beyond optional desk phones. This includes an auto-attendant, voicemail to email, business texting capability, and the Linkus UC mobile app. For a solo business owner using only the mobile app, the cost is $25/month — often less than adding a business line to a cell carrier plan, with far more features included.

How to Get a Business Phone Number for Your New Business

When you start a business, your personal cell phone number becomes your business number by default. Clients call it, you give it out on cards, it goes on the website. This works — until it doesn’t. Clients have your personal number forever. You can’t separate work calls from personal calls. When you hire employees, there’s no way to route calls to anyone but you. And if you ever want to change the number, you’re changing it everywhere simultaneously. Here’s how to get a proper business phone number — and what the right choice actually is in 2026.

Option 1: Your Personal Cell Phone (The Default — and Its Problems)

Most new businesses start here, and for a solo founder with minimal call volume, it’s fine initially. But the personal cell as business number has structural problems that compound as the business grows:

You can’t separate work and personal calls. Every call that comes in rings the same device with the same ring. There’s no way to route after-hours calls to voicemail without also routing personal calls. There’s no auto-attendant, no hold music, no call queue.

The number stays with you, not the business. When you hire a receptionist and route calls through your personal cell, every client has your personal number. If you later want to hand off incoming calls to someone else, you can’t — clients are calling you directly.

Your personal number is on record everywhere clients can find it. Once you give your personal number to a client, you’ve lost the ability to reclaim that privacy. Business communications and personal life share one number permanently.

For a business with even one employee or any expectation of growth, starting with a proper business number from day one avoids the painful transition of changing numbers later.

Option 2: A Second Phone Number on Your Cell (Apps Like Google Voice)

Apps like Google Voice, OpenPhone, Grasshopper, and similar services give you a second phone number that rings on your existing smartphone. You get a separate business number without carrying two devices. Calls to the business number ring the app; calls to your personal number ring the regular dialer.

For a very small, very early-stage business — a freelancer, a side business, someone just starting out — this approach works. The cost is low, setup is immediate, and it provides basic separation between personal and business calls.

The limitations become apparent as the business grows:

They don’t scale to a team. These apps are built for individual users. Adding a receptionist, routing calls to different employees, managing a call queue, or setting up an auto-attendant that actually routes to real people is either not possible or requires paid upgrades that quickly approach the cost of a real phone system.

Audio quality and reliability are inconsistent. App-based calling depends on cellular data or Wi-Fi quality at the moment of the call. Dropped calls, latency, and audio quality issues are more frequent than with a proper VoIP system.

Call recording, voicemail to email, business texting, and intercom are either limited or unavailable without significant additional cost.

Option 3: A Real Business Phone System With VoIP (The Right Answer for Most Businesses)

A VoIP business phone system gives you a real business phone number — one that belongs to the business, not to any individual employee — along with the full infrastructure for professional call handling: auto-attendant, ring groups, voicemail to email, business texting, call recording, and a mobile app that extends every extension to cell phones without giving out personal numbers.

For a new business, this means:

Your business number is yours permanently. The number belongs to the system, not to you or any employee. When you hire staff, calls route through the same number. When employees leave, the number and client relationships stay with the business.

You can still use your cell phone. Phonewire’s Linkus UC app turns your existing iPhone or Android into a business extension — you make and receive calls on your business number, not your personal cell. No second device needed. Work calls and personal calls stay completely separate.

The system grows with you. Start with two extensions. Add ten when you hire. Add a reception desk phone when call volume justifies it. Change the auto-attendant greeting when your hours change. None of this requires a technician visit or a contract change — it’s configuration in the system.

The cost is lower than you might expect. Phonewire’s cloud-hosted VoIP for a new small business with 2–5 users runs $25/user/month — often less than a small business pays for individual cell phone plans they’re using for business calls. And unlike carrier phone plans, a VoIP system includes an auto-attendant, voicemail to email, business texting capability, and call routing that a cell carrier plan never will.

What about a traditional landline? A copper POTS landline — the kind connected to your building via physical copper wires from the phone company — is the one option not worth getting for a new business in 2026. AT&T is actively retiring copper lines through 2029, rates are spiking, and copper has none of the features a VoIP system includes. If someone recommends you get a “landline” for your new business, what they mean is a business phone number delivered via VoIP — not a copper wire telephone line.

What Phone Hardware Does a New Business Actually Need?

The answer depends on whether you have staff working from a fixed location. For a home-based business or a business where everyone works remotely, the Linkus UC app on existing cell phones is the only hardware you need — no desk phones required.

For a business with an office where employees take calls at a desk, Phonewire installs physical VoIP desk phones from Yealink, Snom, Poly, or Panasonic — professional phones that connect to your network and deliver better call quality and easier call management than any app-based solution. A reception desk with a proper Yealink phone and BLF panel handles call volume that would overwhelm a smartphone app.

Most new businesses with an office start with a mix: one or two desk phones at the most call-heavy workstations, and the mobile app for everyone else. That combination scales easily as the business grows. See our recommendations for the best desk phones for small business.
