Quick Answer: A virtual number for WhatsApp Business is a cloud-based phone number that lets businesses register and operate WhatsApp Business without a physical SIM.

How to Set Up a Virtual Number for WhatsApp Business: Step-by-Step Guide
What Exactly Is a Virtual Number and How Does It Work?
A virtual phone number, also known as a DID (Direct Inward Dialing) number or VDID (Virtual Direct Inward Dialing) number, is a telephone number that is not directly associated with a specific phone line. Instead, it exists in the cloud and can be routed to any existing phone line or device. VoIP (Voice over Internet Protocol) technology powers most virtual numbers, transmitting voice data as digital packets over the internet rather than through traditional copper telephone lines.
Key features of virtual numbers include:
- Portability: Usable from anywhere with an internet connection.
- Flexibility: Calls can be forwarded to different devices or numbers.
- Cost-effectiveness: Typically 40-60% cheaper than traditional business phone lines (Source: FCC VoIP Consumer Guide).
- Scalability: Add or remove numbers instantly as your team grows.
Why Use a Virtual Number for WhatsApp Business?
Global Reach: Communicate with clients across countries without high roaming charges.
Professionalism: Maintain a dedicated business line for customer support.
Privacy: Protect your personal phone number while staying reachable.
Automation and Analytics: Integrate with tools like FreJun to track messages, call logs, and customer interactions automatically.
Multi-Device Access: Use your WhatsApp Business account on desktop, mobile, and tablet seamlessly.
For WhatsApp Business, a virtual number provides a dedicated business line without the need for an additional physical device or SIM card.
Which Virtual Number Provider Should You Choose?
Selecting the right provider is the single most important decision in this process. Not every virtual number works with WhatsApp Business — providers must support SMS or voice-based OTP delivery, and some VoIP-only numbers are rejected during WhatsApp verification. The table below compares the leading options:
| Provider | Best For | WhatsApp Compatible | Starting Price | Key Feature |
|---|---|---|---|---|
| FreJun | Sales & recruitment teams | Yes | From $14.49/user/mo | CRM integration, auto-dialing, call recording |
| SMS-Magic | WhatsApp API campaigns | Yes | Custom pricing | WhatsApp Business API, bulk messaging |
| Zoko | E-commerce & support | Yes | From $4.99/mo | Automated messaging, team inbox |
| Grasshopper | Small businesses | Limited | From $14/mo | Call forwarding, voicemail |
| Google Voice | Individual users | Limited | Free (US only) | Basic calls, texts, voicemail |
| OpenPhone | Startups & SMBs | Yes | From $13/user/mo | Team collaboration, call routing |
We recommend FreJun for recruitment and sales teams because it combines virtual number provisioning with automated call logging, CRM sync, and analytics — eliminating the need for separate tools. For teams that only need WhatsApp messaging without voice calling, Zoko offers a lower entry price.
What Are the Benefits of Using a Virtual Number for WhatsApp Business?
Implementing a virtual number for your WhatsApp Business account delivers measurable advantages across privacy, cost, and operational efficiency. Research from Juniper Research projects that business messaging over platforms like WhatsApp will exceed 2.7 trillion messages annually by 2026 (Source: Juniper Research, 2023), making a professional setup essential now.
- Professional Image: A separate business number maintains clear boundaries between personal and business communications.
- Enhanced Privacy: Your personal number stays private, protecting your personal life from business intrusions.
- Improved Organization: Keeping business conversations separate makes it easier to manage customer interactions and track communication history.
- Flexible Number Choice: Choose a number with a specific area code for local marketing or regional expansion.
- Easy Scalability: Add numbers for different departments or locations without additional hardware.
- Cost-Effective: Virtual numbers cost 40-60% less than traditional business phone lines, especially for international communications.
- Advanced Features: Call forwarding, voicemail-to-email, and analytics are standard with most providers.
- Seamless Integration: Virtual numbers connect directly with CRM systems, streamlining your workflow.
How Do You Choose the Right Virtual Number Provider?
Selecting the appropriate virtual number provider is critical for a smooth WhatsApp Business experience. Evaluate each option against these four criteria:
- WhatsApp Compatibility: Confirm the provider’s numbers can receive SMS or voice OTPs for WhatsApp Business verification. Not all virtual numbers qualify.
- Geographic Coverage: Check that the provider offers numbers in every region where you operate or plan to expand.
- Reliability and Uptime: Look for providers with documented 99.9% uptime SLAs and transparent incident histories.
- Additional Features: Prioritize providers offering call forwarding, voicemail, SMS, and CRM integration in a single platform.
Some leading virtual number providers and WhatsApp Business solutions include:
- FreJun: Streamlines outbound call operations with automated dialing, call tracking, and integration with your favorite workflow tools. FreJun allows click-to-call and autodial features while automatically logging and recording all conversations. Advanced analytics track team performance and boost productivity.
- SMS-Magic: Offers WhatsApp Business API solutions with advanced features for customer engagement and support.
- Zoko: Provides WhatsApp Business API integration with automated messaging and customer management tools.

- Google Voice: Delivers a personal phone number for calls, texts, and voicemail in select regions.
- Sideline: Offers a second phone number with text messaging, call forwarding, and voicemail.
- OpenPhone: Provides a business phone system with call routing, team collaboration, and text messaging.
- Hushed: Delivers private phone numbers for secure calls and texts with added privacy controls.
The biggest mistake teams make is choosing a provider based on price alone, then discovering the number fails WhatsApp OTP verification. Always confirm WhatsApp compatibility before purchasing.
How Does Customer Engagement Improve with a Virtual WhatsApp Number?
Teams that route customer conversations through a dedicated virtual WhatsApp number report faster response times and higher satisfaction scores. A dedicated number enables label-based chat organization, quick-reply templates, and automated away messages — features unavailable on personal WhatsApp. When connected to a platform like FreJun, every WhatsApp interaction is logged against the customer record in your CRM, giving managers full visibility into recruiter or sales rep activity without manual data entry.
Step-by-Step Guide to Setting Up Your Virtual Number
Once you have chosen a provider, follow these steps to set up your virtual number:
- Sign Up for an Account: Visit the provider’s website and create an account. Provide your business details and payment method.
- Choose Your Number: Select a number that fits your business needs — local, toll-free, or international. Confirm it is compatible with WhatsApp Business verification before purchasing.
- Verify Your Identity: Most providers require identity verification to prevent fraud. Have a government-issued ID ready.
- Configure Your Settings: Set up call forwarding if needed. Configure voicemail and any additional features your provider offers.
- Download Associated Apps: If your provider offers a mobile or desktop app, download and configure it now.
- Test Your Number: Make a test call or send a test message to confirm everything works before proceeding to WhatsApp setup.
How Do You Configure WhatsApp Business with Your Virtual Number?

Some providers require you to retrieve the code through their dashboard.
- Complete Business Profile Setup: Enter your business name, category, and other relevant details. Add your business logo as the profile picture.
- Configure Business Settings: Set your business hours, away messages, and quick replies. Explore catalogs or shopping carts if relevant to your business.

Based on FreJun’s 2025 analysis of 300+ recruitment and sales client accounts, teams that connected a virtual WhatsApp Business number to FreJun’s CRM integration saw a 23% reduction in missed follow-ups and a 17% improvement in candidate response rates within the first 60 days. The data consistently showed that automated call logging — eliminating manual note-taking after each WhatsApp interaction — saved recruiters an average of 45 minutes per day. For a 10-person recruitment team, that translates to roughly 75 hours of recovered capacity every month. We also found that teams using the “Call Me” verification method during WhatsApp setup had a 94% first-attempt success rate, compared to 61% for SMS-only verification on virtual numbers.
In our experience deploying virtual communication tools for 500+ companies, the most overlooked factor is confirming WhatsApp OTP compatibility before purchasing a virtual number.

Frequently Asked Questions About Virtual Numbers for WhatsApp Business
1. What is a virtual number for WhatsApp Business?
A virtual number is a cloud-hosted phone number not tied to a physical SIM card or landline. Businesses use it to register and operate a WhatsApp Business account, enabling professional customer communication, multi-agent access, and CRM integration. Unlike personal numbers, virtual numbers can be provisioned instantly, assigned to teams, and cancelled without hardware changes. Setup typically takes 10 to 30 minutes with a compatible provider like FreJun.
2. Can I use the same virtual number for WhatsApp and regular calls?
Yes, most virtual number providers support both WhatsApp messaging and regular voice calls through the same number. Platforms like FreJun route inbound and outbound calls through the same virtual number used for WhatsApp verification, so your team operates from a single business identity. Check with your provider that both SMS reception and voice calling are enabled on the number before purchasing.
3. How do I verify my virtual number on WhatsApp Business?
During WhatsApp Business setup, enter your virtual number and select the “Call Me” verification option rather than SMS. WhatsApp will call the number and read a 6-digit code. This method works reliably for most virtual and VoIP numbers. If the call does not connect, check that your provider has voice calling enabled and that the number is not flagged as a VoIP-only line, which WhatsApp occasionally rejects.
4. What are the benefits of using a virtual number for WhatsApp Business?
Virtual numbers protect personal privacy, project a professional business identity, and enable multi-agent access from a single WhatsApp Business account. They cost 40-60% less than traditional business lines, support international communication without roaming fees, and integrate with CRM platforms for automatic conversation logging. For recruitment and sales teams, the biggest gain is eliminating manual note-taking after every customer interaction.
5. Which types of businesses benefit most from a virtual number for WhatsApp Business?
Recruitment agencies, SaaS sales teams, e-commerce brands, and remote-first companies gain the most from virtual WhatsApp Business numbers. Any team handling high volumes of customer conversations across multiple time zones benefits from the automation, labeling, and CRM integration that a virtual number setup enables. Small businesses and solo founders also benefit from the professional image a dedicated business number provides.
6. Is it legal to use a virtual number for WhatsApp Business?
Yes, using a virtual number for WhatsApp Business is legal in most jurisdictions, provided the number comes from a licensed provider and your communications comply with local regulations. In the EU, GDPR applies to all customer data processed over WhatsApp. In California, CCPA governs data handling. Always obtain explicit customer consent before initiating business messaging and maintain records of that consent for compliance purposes.
7. What features should I look for when selecting a virtual number provider for WhatsApp Business?
Prioritize WhatsApp OTP compatibility (SMS and voice), 99.9% uptime SLA, international number availability, and CRM integration. Providers like FreJun add automated call logging, click-to-call dialing, and analytics on top of basic virtual number functionality. Avoid providers that only offer SMS reception without voice calling, as WhatsApp’s “Call Me” verification is the most reliable fallback when SMS delivery fails.
8. Can I use a virtual number for WhatsApp Business internationally?
Yes, virtual numbers allow businesses to acquire local numbers in multiple countries and use each one to register a separate WhatsApp Business account or connect to the WhatsApp Business API. This lets global teams present local phone numbers to customers in each market, improving answer rates and trust. FreJun supports virtual number provisioning across multiple countries for teams operating internationally.
9. Do I need a special app to use a virtual number for WhatsApp?
No special app is required beyond the official WhatsApp Business app. Your virtual number must support SMS or voice OTP delivery for the initial verification step. After verification, WhatsApp Business operates normally on any device. Some providers, including FreJun, offer companion apps that add call automation and CRM logging on top of WhatsApp, but these are optional enhancements rather than requirements.
10. Is FreJun suitable for verifying WhatsApp Business numbers?
Yes, FreJun virtual numbers support WhatsApp Business verification via both SMS and voice call. Beyond verification, FreJun provides CRM integration, automated call logging, click-to-call dialing, and conversation analytics. Recruitment and sales teams using FreJun report a 23% reduction in missed follow-ups after connecting their virtual WhatsApp Business number to FreJun’s CRM sync, based on FreJun’s 2025 client data analysis.
11. Are virtual numbers secure for business communication?
Virtual numbers from reputable providers use TLS (Transport Layer Security) encryption for call signaling and SRTP (Secure Real-time Transport Protocol) for voice data. WhatsApp Business adds end-to-end encryption for all messages. When using a trusted provider like FreJun, your virtual number communications are encrypted in transit and access-controlled at the account level, meeting standard business messaging security requirements.
12. How long does it take to set up a virtual number with WhatsApp Business?
Setup typically takes 10 to 30 minutes from account creation to first message sent. The main variables are provider identity verification time (instant to 24 hours depending on the provider) and WhatsApp OTP delivery speed. FreJun users who select the “Call Me” verification method during WhatsApp setup report a 94% first-attempt success rate, completing the full setup in under 20 minutes in most cases.
