I know this may have been discussed but i cannot find any useful jnfo on this.
How do I find my club code?
@GMSA_IDPA you will need to address this question to the organization that is maintaining those club codes (e.g. IDPA, USPSA, etc).
In PractiScore, the club codes are optional and only used for the reference or to fulfill the requirements of match result exports for a given governing sport body.
