The owner/partner or authorised representative may report an alternate address with the Registrar.
The alternate address must be located in the same jurisdiction as the individual’s residential address.
Therefore if the owner/partner or authorised representative is locally resident, his alternate address cannot be a foreign address.
The alternate address cannot be a P.O. Box address and must be an address where the person can be contacted
