What type of identifiers may gangs use to signify membership?

Gangs often use street names as a way to signify membership, as these names can serve as informal identifiers within the group. They allow members to establish a sense of identity and loyalty, and can also act as a shorthand for relationships, statuses, or rank within the gang. Street names often reflect aspects of an individual’s personality, background, or experience, making them a significant part of gang culture.

While physical documents, postal addresses, and name tags may serve legitimate purposes in more formal settings, they do not carry the same weight as street names in the context of gang affiliation. These other choices do not reflect the underground or informal nature of gang identity, which is usually communicated through symbols, codes, and names rather than official identifiers. Thus, street names are a clear and culturally relevant means by which gang members demonstrate their allegiance and identity.
