Flags

Every country flag on 4chan. Note that this image includes England, Scotland, and Wales. It also includes the Unknown flag.

Five boards on 4chan currently have flags. Four of them have country flags, which display the country you're posting from (or the location of your VPN or proxy if you are using one.) Flags are used on 4chan as a method of pseudo-identification.

Country Flags

Anons reacting to a rare flag sighting

Country flags, or geoflags, display the country of the IP address that was used to submit a post. This flag is displayed to the right of a poster's name, or to the right of their ID, depending on the board. There are around 254 countries that can appear. During certain sporting events, /sp/ gains specific flags for England, Scotland, and Wales. These flags can very rarely be found on /pol/ and /bant/ if a thread is moved from /sp/. Outside of these events, posting from one of those countries would normally display a Union Jack labelled United Kingdom.

Unknown Flag

"Unknown" is a relatively common flag on 4chan. It appears when a thread is moved from a board without flags to a board with them, as on flag-boards ever post must have one. Its ID is XX.

Rare Flags

Ditto

Certain flags are more common to find than others. Countries with very low populations, or limited access to the Internet can be very rare to come across while browsing 4chan. These are often referred to as rare flags, and are pointed out by many when they are sighted.

Retired Flags

There are various flags that have been retired, and now will no longer appear on posts from their previous IP ranges. Not much is known about them; we can only infer from the archives that they have been retired due to an extremely long time since the last post from that country.

Other	O1	n/a	0	(presumably)	On the drop-down on 4plebs. Not sure if this was ever even on 4chan.

Outdated Flags

Over the years some flags have been updated.

Country	ID	Notes
Antarctica	AQ
Brunei	BN	This flag was posted on /pol/ with the filename "Brunei__Saturated_Glitch_.gif" which implies the saturation was applied by accident
Libya (prev. Libyan Arab Jamahiriya)	LY
Montenegro	MM
Uzbekistan	UZ
Holy See	VA
Kosovo	XK	Andorra was used as a placeholder until Kosovo's flag was added

Board Flags

Board flags, previously troll flags, are colloquially referred to as meme flags by most posters. These flags are not determined by poster location, and instead can be chosen from a drop-down menu underneath the posting field.
