For security purposes, Facebook requires users with unverified accounts to enter into an input box a series of characters that appear on-screen when sending friend requests to other users. The captcha security measure lets Facebook know that there is a real person on the other end of the request. As an alternative to entering a captcha each time you send a friend request, you have the option to verify your account with Facebook. You can do so using a text-message code sent to your mobile phone or by using a valid email address from an affiliate university or college.
Click the "Verify" link found below the captcha that appears when sending a friend request.
Enter your mobile phone number by selecting your country code and keying in your phone number without any special characters or leading zeros.
Follow the prompts to have a confirmation code sent to your mobile phone.
Enter the code that you receive in the "Code" field and click the "Confirm" button.
