About international phone number format

A phone number in full international format includes a plus sign (+), then country code, city code, and local phone number. When contacting WhatsApp, always send your phone number in full international format.
For example, if a contact in the United States (country code "1") has the area code "408" and phone number "XXX-XXXX", you'd enter +1 408 XXX XXXX. If a contact in Portugal (country code "351") has the area code "21" and phone number "XXX-XXXX", you'd enter +351 21 XXX XXXX.
Remember to remove any leading 0s or special calling codes from the phone number, as these can cause errors during registration.

Note:

  • Make sure to remove any leading 0s or special calling codes.
  • All phone numbers in Argentina (country code "54") should have a "9" between the country code and area code. The prefix "15" must be removed so the final number will have 13 digits total: +54 9 XXX XXX XXXX
  • Phone numbers in Mexico (country code "52") need to have "1" after "+52", even if they're Nextel numbers.
  • WhatsApp is designed for mobile phones and may not work with landlines. If you're trying to register a landline number, you may encounter errors.
  • If you're not receiving a verification code, try checking your phone's spam filter or restarting your phone. If you're still having trouble, try re-registering your phone number after a few hours.
