How to register your phone number

Android
iOS
We send you a registration code to confirm that you own the phone number you want to use on WhatsApp. After registering your phone number with WhatsApp you can choose to set up a Passkey for future verification.
Registration requirements
  • You can only register a phone number you own.
  • You must be able to receive phone calls and SMS to the phone number you are trying to register.
  • You must have any call-blocking settings, apps or task killers disabled.
  • You must have a working internet connection through mobile data or Wi-Fi. If you're roaming or have a bad connection, registration may not work.
    • To check if you’re connected to the internet, try opening www.whatsapp.com on your phone’s Internet browser.
  • You’ll need to use a supported phone number. Unsupported phone numbers can’t be registered on WhatsApp and include:
    • VoIP
    • Landlines
      Note: Landlines are only supported on the WhatsApp Business app.
    • Toll-free numbers
    • Paid premium numbers
    • Universal access numbers (UAN)
How to register
  1. Enter your phone number. Choose your country from the drop-down list. This will automatically fill your country code on the left. Don't put 0 before your phone number.
  2. You can register with a voice call or an SMS message. Tap Next to request a code.
Note: Depending on your carrier, you might receive charges for SMS messages and phone calls.
Troubleshooting steps
If you didn't receive the 6-digit code by SMS:
  • Wait for the progress bar to finish and retry. The wait may take up to 10 minutes.
  • Don't guess the code, or you’ll be locked out for a period of time.
  • If the timer runs out before you receive the code, an option will appear to request a phone call. Choose the Call me option to request the call. When you answer the call, an automated voice will tell you the 6-digit code. Insert that to verify WhatsApp.
If you have issues registering, try:
  • Turning your phone off, waiting for 30 seconds, and turning it back on.
  • Deleting and reinstalling the latest version of WhatsApp.
  • Send a test SMS message or make a phone call from any phone to your own phone number exactly as you entered it in WhatsApp, including the country code, to check your reception.
Create a passkey
Note: This feature may not be available to you yet.
You can use your fingerprint, face, or screen lock to verify it’s you with a passkey. When you register your phone number for WhatsApp on Android, you can use a passkey instead of an SMS. To set up a passkey, you’ll need an Android 9 or later model device with:
  • Your Google account set up and linked to your mobile device.
  • Lock screen set up
  • Password Manager set up. You can check if you have this enabled in your device Settings > Passwords & accounts.
  • The latest version of Google Play Store installed. This should happen automatically, but you can see if an update is available in your device Settings > Security & Privacy > System & Updates.
To create a passkey:
  1. Go to your WhatsApp settings.
  2. Tap Passkeys > Create a passkey.
  3. Tap Continue
    • You may be asked to tap Use screen lock to create your passkey.
Note: If you are reinstalling WhatsApp and have previously created a passkey, you may be asked if you want to use that passkey at registration.
Remove a passkey
To remove a passkey, go to your WhatsApp Settings > Account > Passkeys and tap Revoke.
