In this guide, we will explore how to get a virtual number for WhatsApp, the benefits of having a virtual number, and how to use it effectively for your business.

What is a Virtual Number?

A virtual number is a phone number that is not tied to a physical SIM card or a specific mobile network operator. It exists solely in the virtual realm and functions just like a regular phone number for sending and receiving texts, calls via WhatsApp or sending WhatsApp OTPs.
Having a virtual number allows businesses to communicate with their customers on WhatsApp without revealing their personal phone numbers.

How to Get a Virtual Number for WhatsApp?

  1. Select a Provider: The first step is to select a reliable provider for the phone number. The provider should comply with data privacy and GDPR regulations. One also has to ensure high availability and uptime. Support is also another parameter to consider while selecting a provider.
  2. Registration: You’d now have to register with the provider according to their process. There would be a need for some documentation and payment. You’d also get to select the geography and the phone number. You can also get a customized number if it is available.
  3. WhatsApp Verification: Once the number is purchased, you’d have to link the same to your Facebook business manager and get it verified. There will be an OTP verification process for the same.

Once done, you can sign up for a WhatsApp marketing platform like WhatsApp Now and start sending WhatsApp broadcasts. You can also refer to our guide on examples of a WhatsApp broadcast message for reference.  

Benefits of Using a Virtual Number for WhatsApp

There are several advantages to using a virtual number for WhatsApp, making it an essential tool for businesses. Let's explore some of the key benefits:

  1. Privacy: By using a virtual number, businesses can keep their personal phone numbers private while still being able to communicate with their customers. This helps protect their privacy and reduces the risk of unwanted contact or breaches of confidentiality while using them for WhatsApp marketing.  
  2. Global Accessibility: Virtual numbers are not bound by geographical limitations, enabling businesses to communicate with customers worldwide without incurring international calling fees. This opens up new opportunities for international expansion and customer engagement.
  3. Cost-effectiveness: Operating a virtual number is generally more cost-effective than maintaining a traditional mobile line, especially for international communications. Virtual numbers eliminate the need for physical infrastructure and hardware, allowing businesses to scale their operations without significant cost increases.
  4. Flexibility and Convenience: Virtual numbers can be accessed from multiple devices, providing flexibility for businesses and their employees. This ensures that messages and calls can be responded to promptly, regardless of the device being used.
  5. Centralized Management: For businesses that operate multiple numbers, virtual numbers can be easily managed through a single dashboard. This centralized management system simplifies administrative tasks, improves efficiency, and enhances tracking and monitoring capabilities.
  6. Enhanced Security: Virtual numbers often come with advanced security features, such as end-to-end encryption and secure data storage. This ensures that business communications remain confidential and protected from unauthorized access.

Frequently Asked Questions

How do I choose the right OTP service provider?

When selecting an OTP SMS service provider, focus on:

  • Delivery reliability and speed
  • Global coverage and local compliance
  • Multi-channel support and fallback
  • Ease of integration
  • Pricing transparency

The right provider should not just send OTPs but ensure they are delivered consistently across regions and networks.

Not all OTP SMS service providers are built the same.

Some optimize for cost, others for flexibility but very few balance delivery reliability, global coverage and ease of use. And that balance is what actually impacts whether your users receive OTPs on time.

If OTP is critical to your product, focus on:

  • reliable delivery (not just sending)
  • multi-channel fallback
  • scalability across regions

Try It for Yourself

Why is multi-channel OTP important?

Relying only on SMS can lead to failed verifications due to:

  • network issues
  • telecom filtering
  • device limitations

Multi-channel OTP systems (SMS + WhatsApp + voice) improve success rates by automatically retrying through alternative channels if one fails.

What is the best OTP SMS service provider in India?

Some of the commonly used OTP SMS service providers in India include MSG91, Exotel and 2Factor.

That said, India has additional challenges like DLT compliance and operator filtering. Platforms that handle these internally while also offering fallback options tend to provide more consistent OTP delivery.

Which is the cheapest OTP service provider?

Providers like Fast2SMS and 2Factor are often considered among the cheapest OTP service providers, especially in India.

However, lower pricing can come with trade-offs such as:

  • lower route quality
  • higher delivery delays
  • limited fallback options

For mission-critical OTP flows, reliability often matters more than just cost.

Which is the best OTP service provider in 2026?

The best OTP service provider depends on your use case.

  • For global scale and flexibility: Twilio, Infobip
  • For cost-effective APIs: Plivo
  • For India-focused SMS OTP: MSG91, Exotel

However, platforms like Message Central stand out by balancing global coverage, multi-channel fallback and ease of deployment, making them suitable for businesses that prioritize delivery reliability.

What is an OTP service provider?

An OTP service provider enables businesses to send temporary verification codes to users via channels like SMS, WhatsApp or voice to authenticate logins, transactions or sign-ups.

Modern OTP SMS service providers go beyond just sending messages, they ensure reliable delivery using optimized routing, retries and sometimes multi-channel fallback.
