What Is a VoIP Number?
A VoIP number is a regular phone number, in the same format as any other, that is assigned to an internet-based phone account instead of a physical line or SIM card.
Calls and texts to the number are routed over the internet to whichever device you're signed in on: a smartphone app, a laptop, a desk phone, or all three at once. Because the number lives in the cloud, you can pick an area code from almost any city, answer calls from any country, and change devices without changing numbers.
You'll also see VoIP numbers called virtual numbers, cloud numbers, or online phone numbers. The names differ, but the idea is the same: a real phone number you use through an app instead of a SIM card or a wall socket.
Types of VoIP Numbers You Can Get
You can get five kinds of VoIP number: local, toll-free, mobile, vanity, and international. Pricing and verification differ by type, so decide which one you need before you sign up.
| Number type | Looks like | Best for | Typical cost |
| Local (geographic) | +1 (212) 555-0100 | A local presence in a city; a small business main line | US/Canada about $1–$10/mo, often included with a plan; abroad commonly $8–$50/mo |
| Toll-free | +1 (800/833/844/855/866/877/888) | Customer support and national brands; free for callers in the US and Canada | US/Canada about $1–$15/mo plus inbound minutes; abroad often $25–$80/mo |
| Mobile | Country-specific mobile prefix (for example UK 07xxx) | Heavy SMS use and markets where mobile numbers are trusted | Varies widely by country; often stricter verification |
| Vanity | 1-800-FLOWERS | Memorable marketing numbers | Standard number price plus any search or reservation fee; premium numbers cost more |
| International | A local number in another country (+44, +61, +91 …) | Serving customers abroad without an office there | Commonly $8–$50+/mo, depending on country and type |
Two more distinctions matter when you choose.
Fixed vs. non-fixed A fixed VoIP number is tied to a verified physical address; a non-fixed one isn't. Banks and verification systems trust fixed numbers more, and some countries require them.
Voice-only vs. SMS-enabled Not every VoIP number can send and receive texts. If you need SMS for customer messages or one-time codes, confirm the number is SMS-enabled before you buy.
What You Need Before You Start
You need an internet connection, a device to take calls on, and, depending on the country, identity or business documents. No special hardware is required.
- A stable internet connection: Each call uses roughly 100 kbps in each direction, so ordinary broadband or 4G/5G handles several calls at once.
- A device: A smartphone, a computer with a browser or desktop app, or an IP desk phone. Most people start with the mobile app.
- Documents, where the country requires them: US and Canada numbers need only an account and a payment method. Numbers in the UK and many other countries may need a government ID, proof of address, or business registration, depending on the country, the number type, and whether you're buying as an individual or a business.
- An emergency address: In the US, VoIP providers must route 911 calls and pass on your registered location, so you'll be asked for a physical address during setup.
- Business details for texting (US): If you'll send business texts from a US local number, carriers require A2P 10DLC brand and campaign registration. Have your legal business name, EIN, and website ready.
How to Get a VoIP Number in 7 Steps
Getting a VoIP number takes seven steps: define what you need, choose a provider, pick a number, complete verification, activate it, configure it, and test it. For a US or Canada number, the first five usually take under ten minutes.
Step 1: Define what you need
Decide who the number is for, where your callers are, and whether you need texts. Those three answers narrow the provider list before you open a single pricing page.
- Personal or business: A second personal line needs little more than a number and an app. A business line usually needs call routing, voicemail, shared access, and a per-user plan.
- Country and area code: A plumber in Austin wants a 512 number. A software company selling into the UK wants a +44 number, even if the team sits in Toronto.
- Voice, SMS, or both: If you need texts, filter for SMS-enabled numbers from the start.
- New or existing number: If customers already know your number, plan to port it rather than replace it.
Step 2: Choose a provider
Pick a provider that sells numbers in the countries you need, prices the way you'll use it, and makes porting straightforward. Providers differ more than their homepages suggest, so compare them on these points rather than the headline price.
Number coverage Some providers sell US numbers only; others cover 100+ countries.
Pricing model Per-user plans (most cost $15–$50 per user per month) suit teams; pay-as-you-go suits a single number with light use. Check whether minutes, texts, and a number are included or billed separately.
Features you'll use Call forwarding, IVR, voicemail transcription, call recording, a shared inbox, CRM integrations, AI call reports. Don't pay for a call-centre suite if you need one line.
Porting Some providers port numbers in at no charge; others charge a one-time fee, commonly $10–$50 per number.
Security and reliability Look for encrypted calls, STIR/SHAKEN caller ID attestation, a published uptime record, and clear 911 handling.
Support Quick answers matter when a number stops ringing on a Friday afternoon.
Step 3: Pick a number
Choose the number type first, then the country and area code, then the digits. In the provider's dashboard, search available numbers by country, type, and city, and pick one you like.
If you're torn between a local and a toll-free number, the short version is: local numbers build trust with nearby customers and cost less to run, while toll-free numbers signal a national presence and are free for callers. Vanity numbers are searched by the letter pattern you want; not every combination is available.
Step 4: Complete verification
Verification is what stands between signing up and having a live number. How much you need depends on the country, the number type, and whether you're an individual or a business.
| Number location | What's usually required |
| US and Canada | An account and payment method; no documents for most local and toll-free numbers |
| UK | Often proof of identity, and for some number types proof of address or business details |
| EU countries (for example Germany, France, Spain) | Government ID, plus proof of a local address for geographic numbers |
| Australia, Singapore, India, and others | Government ID; business registration for business numbers; a local address in many cases |
| Mobile numbers (any country) | Usually the strictest: ID plus address, and some countries limit them to residents |
These rules are set by each country's telecom regulator, not the provider. Uploading clear, current documents up front avoids the most common delay: a rejected submission.
Step 5: Activate and set up
Once the number is approved, sign in on the devices you want it to ring on. US and Canada numbers are typically working within minutes; numbers that need document review go live once the review is complete.
- Install the provider's mobile app and sign in, so calls ring on your phone.
- Add the desktop app or use the browser dialer for calls from your computer.
- Connect any IP desk phones with the SIP credentials the provider gives you (many small businesses skip desk phones entirely).
- Enter your emergency address so 911 (or 999/112) calls route correctly.
Step 6: Configure the number
The number works as soon as it's active, but ten minutes of configuration is the difference between a line that rings and a line that answers professionally.
Caller ID Set the business name and number that appear when you call out, and register them with carrier analytics services to reduce the chance of a "Spam Likely" label.
Business hours and forwarding Use business hours to decide where calls go after closing time: voicemail, a mobile, or a colleague.
Voicemail Record a greeting and turn on voicemail transcription so you can read messages as text.
IVR (for businesses) An IVR menu ("press 1 for sales, 2 for support") routes callers without a receptionist.
Team access Assign the number to one person or share it with a team.
Step 7: Test, then port
Before you print the number anywhere, make test calls at different times of day, to and from mobiles and landlines. Listen for delay, echo, or dropouts.
If you hear problems, run a VoIP speed test and check your router's QoS settings before blaming the provider. If you're keeping an existing number, this is the moment to submit the port request.
How to Get a VoIP Number for Free
You can get a VoIP number for free in three ways: included with a paid business plan, through Google Voice if you're in the US, or from an ad-supported app. Each has trade-offs.
Included with a paid plan Many business VoIP providers include one local number with every paid plan, sometimes with a monthly bundle of minutes and texts. You pay for the plan, not the number, which makes this the most dependable option for a business line.
Google Voice (personal) Google Voice offers a free US number with calling, texting, and voicemail. You must be in the US and already have a US phone number to sign up, and business features require a paid Google Workspace subscription.
Ad-supported apps TextNow and similar apps give you a US or Canadian number in exchange for ads and limited features. They can reclaim the number if you don't use it, and many apps and banks refuse these numbers for verification codes.
How Much Does a VoIP Number Cost?
A VoIP number costs from about $1 a month to $50 or more, depending on the country, the number type, and the provider. If you need a business plan around it, most plans cost $15–$50 per user per month, plus any usage beyond what the plan includes.
VoIP pricing has four parts, and knowing them stops you comparing a "$2 number" with a "$15 plan".
| Cost component | Typical range (2026) | Notes |
| The number | About $1 to $50+/month | US and Canada numbers are cheapest; numbers in many other countries, and toll-free numbers abroad, cost far more |
| User plan | $10–$150+/user/month (most $15–$50) | Covers the apps and features; calling may be unlimited, bundled, or metered |
| Usage | Domestic calls often included; international from about $0.01 to $1+/min | Depends on the plan and destination; US business texting adds carrier surcharges |
| One-time fees | $0 to a few hundred dollars | Porting, setup fees in some countries, vanity numbers, texting registration |
If you call or text one country a lot, look for prepaid country packs. Calilio, for example, sells calling, SMS, and combo packs for specific countries through the Calilio Hub, in a range of sizes and validity periods, which brings the per-minute cost below pay-as-you-go rates.
A single US number with light use can cost a few dollars a month. A five-person business on a mid-tier plan with call routing and recording typically spends $100–$300 a month before taxes, while numbers in several countries can add $50 or more per number.
How to Keep Your Existing Number: Porting to VoIP
You keep your existing number by porting it to your VoIP provider. If customers already know it, don't replace it.
In the US, the FCC guarantees your right to move a number between wireline, wireless, and VoIP providers, and your old carrier cannot refuse the port even if you owe them money. Simple ports must complete within one business day; ports with several numbers or a landline-to-VoIP move usually take a few days to two weeks. Number porting follows five steps:
- Check portability: Enter the number in the new provider's porting tool. Almost all US, Canadian, and UK numbers can be ported.
- Gather your account details: The account number, the billing name and address exactly as they appear on your bill, and the account or port-out PIN.
- Sign a letter of authorization: This is your written permission for the new provider to move the number.
- Keep the old service active: Cancelling before the port completes can release the number for good.
- Confirm on the port date: Check that calls and texts arrive on the new service before you cancel the old one.
Mismatched billing details are the most common reason ports are rejected, so copy them from an actual bill.
How to Get an International VoIP Number
Getting an international number follows the same seven steps, with two differences: verification is usually stricter, and not every number type is available in every country.
Expect to upload documents Most countries outside North America ask for a passport or national ID, and many want a local address for geographic numbers. Some restrict certain number types to registered local businesses.
Availability varies by type Toll-free numbers are widely available; mobile numbers are restricted or unavailable in some markets.
Check routing rules A few countries limit forwarding calls from a local number to a phone abroad.
Plan SMS separately SMS-enabled international numbers are less common than voice-only ones.
Use one provider for every country A provider with international coverage lets you manage virtual phone numbers in several countries from one dashboard, which is far simpler than opening an account with a carrier in each country.
How to Get a Temporary VoIP Number
A temporary VoIP number is one you use for weeks or months and then release. It's the same kind of number, bought on a month-to-month plan instead of kept for years.
When a temporary number makes sense
A short-term number is useful whenever you need a separate line for a limited time and don't want to hand out your main number.
Marketing campaigns A dedicated number per campaign or ad shows exactly which one made the phone ring.
Events and short projects A pop-up shop, a trade show, or a three-month contract can have its own line that you close when it ends.
Travel and relocation A local number in the country you're visiting or moving to makes local calls cheaper and easier while you're there.
Online listings and sign-ups Sellers, landlords, and freelancers use a separate number to keep their personal one off public listings.
Testing Developers and QA teams use temporary numbers to test calling, SMS, and verification flows before launch.
How to get one
You get a temporary number the same way as a permanent one, then release it when you're finished.
Step 1: Choose a monthly plan Pick a provider that bills month to month, so you can stop paying when you no longer need the number.
Step 2: Add a number Choose the country, area code, and type, and complete any verification the country requires.
Step 3: Use and track it Forward calls to your phone or team, and use call reports to see how the number performs.
Step 4: Release it Delete the number from your account when the campaign or project ends, and update anywhere it was published.
What to watch out for
Temporary numbers work well for short-term calling and texting, but they have limits worth knowing before you rely on one.
Released numbers get reused Once you release a number, the provider can reassign it to someone else, who may then receive calls meant for you.
Don't use them for important accounts Banks, email providers, and government services use your number to recover your account, so give them a number you'll keep.
Free "receive SMS" websites aren't private Public inbox sites show every message to anyone, and many services block their numbers. A number in your own account is the only private option.
Can You Text With a VoIP Number?
Yes, you can text from a VoIP number if it is SMS-enabled and, for US business use, properly registered.
US local numbers Businesses must complete A2P 10DLC brand and campaign registration before carriers will deliver their messages. Unregistered traffic is filtered or blocked.
US toll-free numbers These go through a separate toll-free verification.
Personal use A single personal number generally works without registration, subject to carrier spam filters.
Your provider submits the registration; you supply the business details. Approval usually takes a few days.
Common Problems When Getting a VoIP Number (and Fixes)
Most trouble with a new VoIP number comes down to five things: verification blocks, spam labels, rejected documents, call quality, and reclaimed free numbers. Each has a clear fix.
"This number can't be used for verification" Some apps and banks block numbers they identify as non-fixed VoIP. Choose a fixed VoIP number from a business provider, or a mobile-type number where available.
Calls show as "Spam Likely" New numbers, high outbound volume, and very short calls raise spam scores. Register your caller ID with carrier analytics services, ramp up call volume gradually, and use a provider that signs calls with full STIR/SHAKEN attestation.
Documents rejected Usually a blurry scan, an expired ID, or an address that doesn't match. Resubmit a clear photo of a current document.
Poor call quality Almost always the network rather than the number. Turn on QoS in your router, avoid congested Wi-Fi, and test your connection's jitter and packet loss.
Number reclaimed Free services reclaim inactive numbers. If a number matters, keep it on a paid plan.
Are VoIP Numbers Legal and Safe?
VoIP numbers are legal in the US, Canada, the UK, the EU, Australia, and most of the world, and they're used by hospitals, banks, and government agencies. A few countries restrict consumer VoIP apps, so check local rules before relying on one while travelling.
With a reputable provider, calls are encrypted in transit, and your account should be protected with a strong password and two-factor authentication. The bigger risk is voice-phishing calls that spoof caller IDs: never give account details to a caller you weren't expecting, and call back on a number you trust.
VoIP Number vs. Landline vs. Mobile SIM
A VoIP number is the fastest of the three to set up, the only one that rings on several devices at once, and the only one that lets you choose any area code or country. Landlines and SIMs keep one advantage: they don't need an internet connection.
| # | VoIP number | Landline | Mobile SIM |
| Setup time | Minutes (longer where documents are needed) | Days to weeks | Same day |
| Works on several devices | Yes, at the same time | No | No |
| Any area code or country | Yes | Only your local exchange | Only your home country |
| Typical monthly cost | From about $1 for a US number; most business plans $15–$50 per user | About $20–$80 per line | Varies by carrier and plan |
| International calling | Low per-minute rates | Expensive | Expensive or plan-dependent |
| Needs internet | Yes | No | No |
| Future-proof | Yes | Being retired (UK: January 2027) | Yes |

Frequently Asked Questions
Short answers to the questions people ask most before getting a VoIP number.
How do I get a VoIP number?
Sign up with a VoIP provider, choose a local, toll-free, mobile, or international number in the country and area code you want, complete any verification the country requires, and activate the number in the provider's app.
Can I get a VoIP number for free?
Yes. Google Voice offers a free US number to US residents who already have a US phone number, ad-supported apps offer free numbers with limits, and many business providers include a local number with a paid plan.
How much does a VoIP number cost?
It depends on the country and type. US and Canada numbers typically cost about $1–$10 a month, while numbers in many other countries cost $8–$50 or more, and toll-free numbers abroad can cost $25–$80. Business plans that include a number usually cost $15–$50 per user per month.
Can I keep my existing phone number when switching to VoIP?
Yes. Porting moves a landline, mobile, or toll-free number to a VoIP provider. In the US, your old carrier cannot refuse the port, and simple ports must complete within one business day. Keep the old service active until the port finishes.
How long does it take to get a VoIP number?
A US or Canada number is usually live within minutes, with no documents. Numbers in the UK and many other countries go live once your ID or business documents are approved, which can take from a few hours to a few business days. Ported numbers take from one business day to a few weeks.
Can I get a VoIP number in another country?
Yes. Providers with international coverage offer local, mobile, and toll-free numbers in dozens of countries. Expect to provide a government ID and, for many countries, proof of a local address.
Can I use a VoIP number for WhatsApp, Telegram, or bank verification?
Often, but not always. Many services accept VoIP numbers, but some block numbers classed as non-fixed VoIP. A fixed or mobile-type VoIP number has the best chance; test it with a low-stakes service before relying on it for banking.
Can a VoIP number receive text messages?
Yes, if the number is SMS-enabled. US businesses texting from local numbers must register under A2P 10DLC, and toll-free numbers need toll-free verification.
Do I need special equipment for a VoIP number?
No. A smartphone with the provider's app, or a computer with a browser, is enough. IP desk phones and headsets are optional.
Can I get a temporary VoIP number?
Yes. Add a number on a month-to-month plan and release it when you're done. Avoid using a temporary number for bank or email accounts, because released numbers can be reassigned to someone else.
What is an online phone number?
An online phone number is another name for a VoIP or virtual number: a real phone number that works through an app over the internet, without a SIM card or landline.
Is a VoIP number the same as a virtual phone number?
In practice, yes. Both describe a number that isn't tied to a physical line or SIM and is delivered over the internet.
