Welcome to sig.codes! This is a gallery of signature codes or “geek codes”.
Geek codes were a trend in the 1990s and 2000s, and have continued into today. Wikipedia lists these as “Internet self-classification codes”, but colloquially most are known as “fan codes”, “signature codes”, or “geek codes”.
Picture this: It’s 1996, and computers are starting to become more common. You
may be a college student with network access, you might visit your local
library, or you might have a personal computer at home with a dial-up internet
connection. You probably have an e-mail address, and can even post on newsgroups
or mailing lists. However, free web hosting is not common, and creating a
website requires some technical skills. You don’t want to introduce yourself
every time a new person joins the group, but you want to describe yourself and
your interests. What do you do? You pull up a website with a code key, create
your geek code, and add it to your the bottom of your email - your email
signature, kept in your .sig file.

Though an early specimen named USECODE was proposed in 1984, signature codes are commonly understood as starting with the unrelated 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 developing alongside the growth of Internet usage and culture known as Eternal September.
As time progressed, many other fandoms and groups produced their own codes and purity tests. Though some of these codes are lost to history, others have specifications still online or preserved through archive.org.
For more details, see a sortable, filterable list of signature codes, or view a histogram graph of all dated versions of all known codes. You can also see a gallery of examples to get a sense of how widely signature codes varied in topic and design.
Adult codes are marked with . Codes that are missing specifications are marked with . If you know anything about those codes, please get in touch.
