The general rule is that you cannot use a PO Box as a company’s registered office. It is important that a company’s official address is real and can be found by a member of the general public.
It is not permitted to use a Royal Mail PO Box service or a third party address that is incomplete. The only time a PO Box address can be used is when a full address including house number and road name is also supplied. For example PO Box 123, 5 The High Street, London. This implies that within a physical address there is a physical Post Office Box service provider that can accept mail on behalf of the company.
If you purchase one of our registered address services there is no need to use a PO Box, you simply use our full address as if you were actually located there.
