Triakosioitriakontatriophobia

Trikosioitriakontatriophobia is the fear of the number 333. It could be feared because it is exactly half of the number 666, commonly known in popular culture as the Devil's Number. It could also be feared because of it being 3 times of the number 3 in digits, or 3*111, which is a 3 -digit number with all 3 numbers the same and adding up the digits of 111 gives you 3.

This number fear is very rare.
