sig.codes Gallery

Welcome to sig.codes! This is a gallery of signature codes or “geek codes”, a trend in the 1990s and 2000s to self-identify in a group by concocting a brief code, often placed in a newsgroup or email signature via a “.sig file”. Wikipedia lists these as “Internet self-classification codes”, but colloquially most are known as “fan codes”, “signature codes”, or “geek codes”.

These codes are commonly understood as starting with the NBCS (Natural Bears Classification System), or “Bear Code”, in 1989/1990. After that, signature codes spread across various groups, with the most popular and prominent being the Geek Code (“The Code of the Geeks”) in 1993. As time progressed, many other fandoms and groups produced their own codes. Though some of these codes are lost to history, others have specifications still online or preserved through archive.org.

Technically, the first documented signature code or self-classification code was the proposed USECODE from 1984, though there is no evidence of that code’s use in other posts, nor evidence of its citation in the creation of any other listed code.

Adult codes are marked with 🔞. Codes that are missing specifications are marked with 🔍. If you know anything about those codes, please get in touch.
