WhatsApp Private Number for Business: Send and Receive with Your Own Number

When customers receive a message from a number they already recognize, communication feels more personal and trustworthy. WhatsApp Private Number lets a business use its own WhatsApp number to send OTP, transaction notifications, reminders and service messages.

What is WhatsApp Private Number?

WhatsApp Private Number is a messaging service that uses your business WhatsApp number as the sender identity. Unlike services that use a random sender number, customers see the number they already associate with your business.

Benefits for business

Use a consistent brand identity, automate OTP and notifications, receive inbound messages through webhook, connect CRM or ERP systems through API and monitor delivery reports.

How does it work?

Connect your business number, prepare your API key, call the sending endpoint from your server and use webhook or delivery reports to process events and monitor message status.

Private Number vs Long Number

Private Number uses your own WhatsApp number, while Long Number uses a service long number. Private Number is a better fit when brand recognition and customer replies are important.
