JSSupported

JavaScript / ECMAScript

Browser-native RegExp. Default if you don't pick.

PYSupported

Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
^[A-Z]{3}$

Raw source: ^[A-Z]{3}$

How it works

^[A-Z]{3}$ requires exactly three uppercase letters, anchored to the full string. This validates the FORMAT but not the existence of the code — pair with a lookup table to ensure it's a real ISO 4217 entry like USD, EUR, GBP.
