One of the most common ways white supremacists signal their affiliation to one another is through the use of coded numbers, abbreviations, and acronyms. These can be seen in tattoos, usernames, garments, logos, and so on. Here are some of the most prominent examples:

14

Fourteen is a reference to a slogan by white supremacist leader David Lane. It consists of the 14 words: "We must secure the existence of our people and a future for white children."

88

Eighty-eight is code for “Heil Hitler,” as "h" is the eighth letter of the alphabet. This is often used in combination with "14" (e.g. 1488, 14-88, or 14/88). It can also refer to the 88 Precepts, which, combined with the Fourteen Words, are the basis for Wotanism (W.O.T.A.N.-ism, or Will of the Aryan Nation-ism), Lane’s white supremacist neo-Pagan religion. This particular code number is a less conclusive sign when it comes to things like online usernames, as it can also indicate that the user was born in 1988.

BH or 28

These can stand for “Blood and Honor” (in the numeric version, "b" is the second letter of the alphabet, and "h" is the eighth). This is a common neo-Nazi slogan and has been the name of several organizations.

ORION

This can stand for “Our Race Is Our Nation.”
