No confirmation email to complete Facebook sign-up process

Sometimes, Facebook forgets (!) to send a confirmation email to complete sing-up process. Without confirmation email, no one can continue on Facebook. So confirmation of email address to complete sign-up on Facebook is a must. But sometimes Facebook does not sent any confirmation email. This is an unknown error. Why this happen is totally unknown to us.

If you go to setting  and click on primary pending email, will see same thing. Your primary email is not confirmed.

Click on "Resend Email" button, but no email will be sent by Facebook to confirm your Facebook account. Check primary, social and spam folders, no social email you will find. User can use the new Facebook account for two or three days with a message at the top bar. After three days, If you log in, you will be redirected to the below page with a message and you will not be able to use your news-feed. But still you can sent and confirm friend requests.

The redirected page instead of news-feed

If you face this problem, you can try one three processes to solve it. We one of them will solve your issue.
1. Click on "Resend Confirmation Email" and check mail box including spam folder.
2. Change email address. It is 100% working method and easy.
3. Report to Facebook. Click here. A report form will appear like below. Complete the form and send it.

We think the first process is better and first. The second option may kill some time. Facebook will take proper steps to solve the issue.
Best of Luck.
