Although it is possible for an observing station to be associated with more than one WIGOS station identifier, it is desirable to associate as few identifiers as possible with an observing station. Therefore, if an observing station is already associated with a WIGOS identifier, or is associated with an identifier issued by a WMO or partner programme, an additional WIGOS station identifier should not be issued.
