Yeah, MCC stands for Mobile Country Code.
You can find it in the dmesg 
"iwl_mvm_get_regdomain Getting regdomain data for ZZ from FW "
" iwl_mvm_update_mcc send MCC update to FW with 'ZZ' src = 16"

Cheers

You could also give some hints how to find the MCC and even tell what it means. Is it Mobile Country Code or what?
