A flag is often stored as two region letters. An app without flag artwork may show those letters instead.
Technical note: Most country flags are stored as a pair of regional-indicator letters. When an app lacks flag artwork, it may display that letter pair instead of a flag.Reviewed by CoolSymbol.now Editorial · August 2, 2026What you need to know
Unicode uses two regional-indicator characters for many country and territory flags.
Some regional flags use a black flag plus tag characters and a cancel tag.
Update the operating system or app when practical and test the complete copied sequence.

01
Country flags start as letter pairs
A flag is not one character. It is two regional indicator letters side by side.
When a device supports that pair, it draws the flag. When it does not, you see the two letters instead.
- Copy both regional indicators
- Do not insert a space between them
- Test the saved text on the target device
02
Subdivision flags use longer sequences
This is why flags fail more often than other emoji. Support is decided per pair, not once for all flags.
03
How to make the meaning reliable
Nothing is broken when it happens. The letters are still the region code, so the information survives.
- Treat artwork as presentation
- Keep location names searchable
- Avoid flags as the only language selector
04
Why flags are built this way
Encoding one character per flag would have made Unicode decide which places count as countries. Building flags from letter pairs moves that decision to the platform instead.
