Creating a Facebook account. Before you can use Facebook, you must create an account. Creating a Facebook account is free. All you need to get started is an email address and a few minutes of your time.
If you're creating a new Facebook account and didn't get the code to confirm your mobile phone number: Make sure that you entered the correct mobile number. Don't use any special characters (+ or -) or leading zeros.
There are certain sms verification sites that provide you fake phone numbers in order to save you from the mobile phone verification step. Since Facebook allow you to create only one phone number for a single account, you can use the numbers from these sites and create multiple accounts with them.
