Although most members tend to be of Latino descent, membership has opened to other backgrounds, including Central American, African American, Middle Eastern, Asian, Caucasian, and Native American. 18th Street have an organized hierarchy. It is unknown who is at the top. On the streets, there are the Shotcallers, their Lieutenants, and the foot-soldiers beneath them.

Cliques generally function independently, but will join forces when combating rival gangs or law enforcement. The 18 Street gang criminal activities have caught the attention of the FBI.

A common identifier is the number 18 (Spanish: dieciocho), which is usually represented in the Roman numerals (X8) (XVIII) (XV3) and sometimes they also use 666 or 99 (6+6+6=18 / 9+9=18). Some use the number 5 meaning the fifth letter of the Alphabet. They also tattoo themselves with the word BEST, which stands for Barrio Eighteen STreet.
