How do I connect a phone number to my WhatsApp account?

To use WhatsApp Business API via MyOperator, you must first register and verify your phone number. Meta requires number verification to confirm ownership and ensure compliance. Verification is done using a one-time password (OTP) sent by SMS or voice call.

✅ Step-by-Step: Register & Verify Your Phone Number

  1. Choose a number that meets WhatsApp’s requirements
    • Must not already be linked to:
      • WhatsApp App (personal)
      • WhatsApp Business App
      • Another WABA
    • Can be a mobile number or landline.
    • Toll-free numbers may not work unless they support SMS/voice.
  2. Select your OTP delivery method
    • During onboarding, WhatsApp will offer SMS or Voice Call.
  3. (Optional) Capture OTP via Voicemail in MyOperator
    • For landlines/MyOperator numbers, you can route the OTP call to voicemail.
    • Configure this in your MyOperator call flow (see tip below).
  4. Enter the OTP in the verification screen
    • Complete the registration process.
    • Once verified, your number is active for template approvals and messaging.

📊 SMS vs. Voice Call Verification

Method

When to Use

Notes

SMS OTP

Mobile numbers with SMS enabled

Fastest and most reliable option. Ensure SMS delivery is supported by carrier.

Voice Call

Landlines or MyOperator numbers without SMS

OTP is read aloud via phone call. Can be captured via voicemail in MyOperator.

💡 Tip: Capturing OTP via Voicemail in MyOperator

  1. Go to Manage → Call Flows in your MyOperator panel.
  2. Add a Voicemail node to the selected number’s flow.
  3. Ensure no agent rings before the voicemail triggers.
  4. Retrieve the OTP from Voicemail Logs in MyOperator.

🛠️ Troubleshooting & Pro Tips

  • ❌ Already Linked Number: Remove the number from any existing WhatsApp app before retrying.
  • ⏱️ Failed Attempts: Too many failed OTP requests may temporarily block verification—wait before retrying.
  • 🌍 Regional Carriers: Some carriers block international SMS—use voice call instead.
  • ✨ Pro Tip: Always test OTP delivery (SMS or call) before final submission. Delays in receiving or entering OTP can slow onboarding by several hours.
