You can forget about 13 as the most unlucky number, because based on the results of a survey that one insurance company did, they consider 243 as the most unluckiest number of all.
As reported by “London Telegraph”, the last four years, 46 percent of the owners of houses and apartments, with the number 243 suffered an accident or damage. For comparison, with a similar fate are only 18 percent of those who are living in houses and apartments with the number 13. In the second place of the top 10 house numbers is 201, and in the third is the number 1. The following numbers are: 190, 240, 241, 221, 217, 218 and 121.
