Want to know how to get a business phone number without buying a second phone? You have four real options, and two of them cost nothing or close to it.
This guide walks through each one in plain English: what it costs, what it's good for, and how to set it up today. It's written for owners of small service businesses in the US, from solo trades to busy offices.
Quick answer
Most small businesses should get a local virtual number that rings on the phone they already carry. It's cheap, it's live in minutes, and you can take it with you if you switch providers.
Why use a separate business phone number?
Once your personal cell is on your website, your Google listing, and your truck, it's public for good. Owners on Reddit say the same thing again and again.
"We used my personal cell number our first year and I still receive calls 5 years later, which I never pick up due to sales calls, resulting in lower customer service." From r/sweatystartup
Your personal number stays with friends and family, not every directory scraper.
A business call looks different from a personal one, so you can answer the right way.
If you hire, hand off, or sell someday, the number goes with the company.
How to get a business phone number: your 4 options
Here's the whole field at a glance. Each option gets its own section below.
| Option | Typical cost | Best for | Watch out for |
|---|---|---|---|
| Second line from your carrier | A monthly line fee | People who want a "real" cell line | Few business features, tied to one phone |
| Google Voice | $0 to $20/mo | Solo owners on a budget | Business texting limits, no one answers for you |
| Virtual number (VoIP app) | Low monthly fee | Most small businesses | Check texting registration is included |
| Toll-free or vanity number | Varies by provider | National brands, ads | Feels less local to nearby customers |
Option 1: A second line from your carrier
Most modern phones support two lines with an eSIM, so your carrier can add a second number to the phone you already own. It's simple, and calls arrive like any other call.
The catch is that it's still a personal-style line. You won't get business greetings, call routing, or a shared inbox, and the number lives on one device.
Option 2: A free business phone number (Google Voice)
If you want a free business phone number, Google Voice is the usual answer. A single US user with a personal Gmail account can use free Google Voice, or pay for Voice Starter ($10/mo) or Voice Standard ($20/mo), without Google Workspace.
It works well as a starter line, and plenty of owners run on it for years. The limits show up around business texting and when you need more than one person on the line.
"In theory you can't do business texting on consumer apps like Sideline and Google Voice. In reality you might be able to get away with it without getting kicked off their networks, but the side effect is some traffic gets filtered out." From r/sweatystartup
We cover plans, setup, and those limits in detail in our Google Voice for business guide.
Option 3: A virtual phone number for business
A virtual phone number for business isn't tied to a SIM card. It lives in an app, rings on your cell, your laptop, or a teammate's phone, and it's usually live within minutes.
This is the best fit for most small businesses. You pick a local area code, add a greeting and business hours, and you have a real second phone number for business without a second phone.
When you compare providers, ask three questions. Can it forward calls, can it text (and is registration included), and can you take the number with you if you leave?
Option 4: Toll-free and vanity numbers (and local vs toll-free)
Toll-free numbers (800, 888, 877 and so on) are mostly handed out first come, first served. A vanity number spells a word, like 1-800-FLOWERS.
For a local service business, a local phone number for business usually wins. A nearby area code tells customers you're around the corner, while toll-free fits companies that sell across the country.
Already have a number? You can keep it
You don't have to start over. According to the FCC, you can keep your number when you switch providers in the same area, even between landline, internet phone, and wireless companies.
This is called porting, and the FCC says simple ports should be processed within one business day. We have step-by-step porting guides for common providers, such as porting out of Google Voice.
Texting from your business number (10DLC in plain English)
Customers will text your business number, so plan for it. In the US, business texting from a regular 10-digit number is called 10DLC, and the business and its provider have to be registered before messages go out reliably.
You can't register on your own. According to The Campaign Registry, a messaging provider registers you, so pick a phone provider that handles it.
How to set up a business phone line: a checklist
Whichever option you pick, these five steps take under an hour.
- Pick a local area code. Match where your customers are.
- Record a greeting. Say the business name first. Our greeting scripts can help.
- Set business hours. Decide what happens to calls at night and on weekends.
- Set up forwarding. Our free call forwarding codes tool shows the exact codes for your carrier.
- Update it everywhere. Google Business Profile, website, invoices, and your truck.

Frequently asked questions
How do I get a business phone number?
Pick one of four options: a second line from your carrier, Google Voice, a virtual phone number app, or a toll-free number. Most small businesses do best with a local virtual number that rings on the phone they already have.
Can I get a business phone number for free?
Yes. Google Voice offers a free tier for a single US user with a personal Gmail account. Paid tiers start at $10/month, and business texting has limits on consumer apps.
Can I keep my existing number for my business?
Usually, yes. The FCC says you can port your number to a new provider in the same area, and simple ports should take about one business day.
Should my business use a local or toll-free number?
A local number is usually better for a local service business, because a nearby area code signals you're close by. Toll-free fits businesses that sell nationally.
Do I need a second phone for a business number?
No. A virtual number or an eSIM second line rings on the phone you already carry.
