* Number [[4 (number)|4]] ([[tetraphobia]]). In [[China]], [[Hong Kong]], [[Taiwan]], [[Singapore]], [[Japan]], [[Korea]], and [[Vietnam]], as well as in some other East Asian and South East Asian countries, it is not uncommon for buildings (including [[offices]], [[apartments]], [[hotels]]) to omit floors with numbers that include the digit 4, and Finnish mobile phone manufacturer Nokia's [[List of Nokia products#1xxx–9xxx series|1xxx-9xxx series of mobile phones]] does not include any model numbers beginning with a 4 (except [[Series 40]], [[Nokia 3410]] and [[Nokia 4.2]]). This originates from [[Classical Chinese]], in which the pronunciation of the word for "four" (四, ''sì'' in Mandarin) is very similar to that of the word for "death" (死, ''sǐ'' in Mandarin), and remains so in the other countries' [[Sino-Xenic]] vocabulary (Korean ''sa'' for both; Japanese ''shi'' for both; Vietnamese ''tứ'' "four" vs. ''tử'' "death"). In [[South Korea]], buildings tend to include the fourth floor in spite of similar pronunciation issues in the Korean language, though some newer buildings may substitute the letter F in the place of the number 4.
* [[Friday the 13th]] (paraskevidekatriaphobia or friggatriskaidekaphobia) is considered to be a day of bad luck in a number of [[western culture]]s. In [[Greece]] and some areas of Latin America, Tuesday the 13th is similarly considered unlucky.{{ref|Note b|2}}
* Number [[17 (number)|17]] ([[heptadecaphobia]]). In Italy, perhaps because in Roman numerals 17 is written XVII, which can be rearranged to VIXI, which in Latin means "I have lived" but can be a [[euphemism]] for "I am dead." In Italy, some planes have no row 17 and some hotels have no room 17.<ref>{{cite news | title=Bad Omen for Italy as Their Unlucky Number Comes Up| url=https://www.independent.co.uk/sport/football/european/bad-omen-for-italy-as-their-unlucky-number-comes-up-400380.html | location=London | work=The Independent | first=Nick | last=Harris | date=15 November 2007}}</ref> In Italy, cruise ships built and operated by [[MSC Cruises]] lack a Deck 17.<ref>{{cite news|url=https://www.usatoday.com/picture-gallery/travel/cruises/2017/02/03/photos-msc-seaside-under-construction-in-italy/97438130/|first=Gene |last=Sloan|work=USA TODAY|title=Photos: MSC Seaside under construction in Italy|date=February 3, 2017|access-date=August 10, 2024}}</ref>
* Number [[39 (number)|39]] ([[triakontenneaphobia]]). There is a belief in some parts of Afghanistan that the number 39 (thrice thirteen) is cursed or a badge of shame.<ref>{{cite web|url=https://www.theguardian.com/world/2011/jun/15/afghanistan-curse-of-number-39|title=The curse of number 39 and the steps Afghans take to avoid it|work=[[The Guardian]]|author=Jon Boone|date=15 June 2011|access-date=28 December 2017}}</ref>
