hexakosioihexekontahexaphobia is the fear of the number 666. the reason for this such a fear is that 666 is the Number of the Beast. this word is derived from ancient greek roots hexakósioi, "six hundred", hexékonta, "sixty", héx, "six", and phóbos, "fear"; literally meaning "fear of six hundred sixty-six". this fear is not common and it doesn't affect their lives much

severe sufferers may try to avoid the number at all times, like blocking the cable channel 666, driving to change their odometer number from 666 to 667, or changing the address from 666 to the one adjacent to it. for example, in 1989 after Ronald Reagan was elected as the U.S. president, he and his wife Nancy moved to a new home in the Bel-Air section of Los Angeles on the 666 St. Cloud Road. they soon changed their street address to 668 due to their fears of the former number.

one of the most infamous designations of the number in the traffic road numbering system is U.S. Highway 666, which proved dangerous statistically. skeptics believe that this was due to the road being improperly designed or maintained for increasing traffic loads; however, many believed that it was actually the highway number that caused accidents and fatalities. this quickly became well aware by the public. Highway 666 changed its name to the Devil’s Highway, and then eventually to U.S. Highway 491.

the phobia is commonly portrayed in a number of horror films such as The Omen and its 2006 remake.
