If a group wishes to vary their designation or cancel registration, they should contact their Customer Relationship Manager by email ldtmailbox@wra.gov.wales.
Os yw grŵp yn dymuno amrywio eu dynodiad neu ganslo eu cofrestriad, dylent gysylltu â'u Rheolwr Cysylltiadau Cwsmeriaid drwy e-bost posttgt@acc.llyw.cymru.
