What is a VoIP number?
A VoIP phone number, short for Voice over Internet Protocol , is a virtual phone number that makes and receives calls over the internet instead of a traditional phone line. Also called an internet phone number, it looks exactly like any other phone number, but it is not tied to a physical location, a desk phone, or a SIM card.
You can use it from a laptop, a mobile phone, or a browser, wherever you have an internet connection. For businesses, this means your team can have real, professional phone numbers without installing any hardware, paying for physical lines, or being stuck at a desk to take calls.
Businesses use VoIP numbers to handle customer calls, run sales and support teams, set up local numbers in new markets, and keep remote teams connected, all without the cost or complexity of a traditional phone system.
The main reasons are cost, flexibility, and reach. VoIP calls are significantly cheaper than landlines, especially for international calls. Your number works on any device, from anywhere. And you can get a local number in a city or country where you have no physical office, making your business look established and accessible to customers worldwide.
How does a VoIP number work?
When you make an outbound call through a VoIP network, your voice is converted into digital data and sent over the internet to whoever you're calling, then instantly converted back into audio on the other end. To the person picking up, it sounds exactly like any regular phone call. The only difference is that there's no phone line, no desk phone, and no hardware involved on your end.
All you need is a reliable internet connection and a device. Once you sign up for VoIP services and log into your VoIP account, your number is active and ready to use - from your laptop, your mobile, or a browser tab.

Types of VoIP phone numbers for business
Local VoIP numbers
A local VoIP number carries the area code of a specific city or region, giving your business a familiar, local presence wherever your customers are. The big advantage? You don't need a physical office there. Whether you're based in New York but want a Dallas number, or you're a fully remote team serving customers across the US, a local VoIP number makes you look and feel like a neighbor. Customers are far more likely to answer calls from a number they recognize.
Toll-free VoIP numbers
A toll-free number , like an 800 or 888 number, lets customers call your business for free. The call cost falls on you, not them. This is a simple but powerful trust signal: it tells customers that reaching you costs them nothing, which lowers the barrier to getting in touch. Toll-free numbers are especially useful for support lines, sales teams, and marketing campaigns where you want to remove every possible reason not to call.
Vanity VoIP numbers
A vanity number is a custom phone number that spells out your brand or uses a memorable sequence of digits. Think 1-800-PLUMBER or 1-800-LAWYERS. Vanity numbers stick in people's minds, they work especially well in advertising, on billboards, and in radio spots where you only have a few seconds to make your number memorable.
International VoIP numbers
An international VoIP number gives your business a local presence in another country - without opening an office there. Get a UK number for your London customers, a German number for your Berlin clients, or an Australian number for your Sydney team. KrispCall offers international VoIP numbers in 100+ countries, making it the simplest way to expand globally without the cost or complexity of a local setup.
Key features of KrispCall VoIP numbers
Global Calling
Make instant international calls to 100+ countries with crystal-clear quality without incurring any international roaming charges or dialing exit codes. Stay connected with clients, remote teams, and partners across every time zone, at a fraction of traditional international call rates.
Text Messages (SMS)
Send and receive SMS globally from your VoIP number, straight from your KrispCall dashboard. Two-way texting lets customers reply instantly, ideal for appointment reminders, order updates, and real-time support conversations.
Voicemail
Never miss a message. When a call goes unanswered, KrispCall captures the voicemail and delivers it straight to your Unified Callbox, alongside call logs and SMS threads, with transcriptions so you can read messages without listening to every recording.
Shared Phone Number
Let your team make calls, send texts, and manage customer conversations from one shared VoIP number. Calls ring across team members simultaneously; whoever picks up first handles it. Full conversation history, contacts, and voicemails are synced for everyone.
Call Forwarding
Easily forward inbound calls to a colleague, mobile phone, or department based on rules you set, by availability, time of day, or line status. Set it up in a few clicks from your KrispCall dashboard, no IT team needed.
Call Transfer
Move a live call to the right agent or department without disconnecting the caller. Choose a warm transfer, where you brief the receiving agent first, or a blind transfer for quick handoffs. Works from any device on KrispCall's VoIP network.
Multiple Phone Numbers
Manage multiple local, toll-free, or international VoIP numbers on a single device. Assign different numbers to different teams, regions, or campaigns, and handle all of them from one KrispCall account without carrying extra phones.
Phone Tree (IVR)

Significantly lower costs

Yes. VoIP numbers can send and receive SMS and MMS messages just like a regular phone number. With KrispCall, you can text customers directly from your VoIP number using the mobile app or browser.
VoIP numbers are used by businesses of all sizes, from solo freelancers who want a professional number separate from their personal phone, to growing startups managing distributed teams, to large enterprises running global call centers. Remote teams, sales teams, customer support teams, and any business that needs to communicate across borders use VoIP numbers every day.
A VoIP number looks exactly like any other phone number. It has a country code, an area code, and a line number, the standard format your customers expect. For example: +1 (415) 555-0192 for a US local number, 1-800-555-0175 for a toll-free number, or +44 20 7946 0301 for a UK number. There is nothing about the number itself that tells a caller it is VoIP.
Fixed (linked to a physical address) and non-fixed (fully virtual, no location attached). Within those, you can get local, toll-free, international, or vanity numbers depending on your business needs.
Secure when used with a reputable provider. Most reputable VoIP providers encrypt all calls and messages. For extra protection, use strong passwords, enable two-factor authentication, and avoid unsecured public Wi-Fi for sensitive calls.
Fixed VoIP numbers are traceable to a physical address. Non-fixed numbers have no location attached, but all calls leave digital records, timestamps, duration, and account details, accessible to law enforcement through legal channels.
Free options exist but come with limited features and poor reliability – not suitable for business use.
Yes. KrispCall supports number porting, transferring your current number from your carrier, and keeping using it on VoIP without your customers noticing any change.
