Some country endings have rules about who can own them. The registry checks, and may refuse a registration that does not meet them.

• .ca (Canada): Canadian citizens and permanent residents, companies registered in Canada, or owners of a trademark registered in Canada.
• .com.au and .au (Australia): Australian citizens and residents, or organisations with an Australian business number (ABN or ACN) or an Australian trademark.

If you are based in the UK, these endings are usually not available to you. UK and regional endings such as .uk, .co.uk, .scot, .wales, .cymru and .london are open to everyone.
