To sign up using a mobile number, you need to be able to receive text messages. If you're having trouble receiving a text message when you try to sign up with your mobile number, please let us know. If you're unable to receive text messages, try signing up for Facebook with your email address instead.

You can only sign up for one Facebook account per email address. If you're seeing an error message that says there's an existing account associated with your email address, review these troubleshooting tips:

• If you already opened a Facebook account using your email address but lost your password, you can request a new password.
• If you share this email address with someone else who already has a Facebook account, you'll need to use a different email address to create your account. You can create an email address for free using websites like Yahoo! and Gmail.
• If you're having trouble creating a Facebook Page for your business or organization, let us know.
• If you think you received this message by mistake, let us know.

Most likely, someone tried to sign up for a Facebook account using your email address by mistake. The sign-up process isn't finished until someone clicks the link in this email, so the easiest thing to do is ignore the email. You can also:

• Click the link at the bottom of the email to let us know this wasn't you
• Add this email address to your account, if you have a Facebook account
