The postal code of the Sydney Opera House is 2000, the postcode used for its Bennelong Point address in Sydney, New South Wales.
The Opera House sits at the eastern side of Sydney Cove, beside Circular Quay and Sydney Harbour. Its street address is generally given as Sydney Opera House, Bennelong Point, Sydney, NSW 2000. In Australia, postcodes are four-digit geographic identifiers used for sorting and delivering mail.
The number can be confused with 2001, which has historically appeared in the Opera House's postal address for its GPO Box. That is a mailing-box postcode rather than the postcode of the building itself. Nearby suburbs and districts also use different codes, including 2060 across the harbour in North Sydney.
The 2000 postcode is also strongly associated with Sydney's central business district and nearby landmark precincts. Thus, the answer refers to the Opera House's physical location, not to a separate box, ticketing office or general postal service address.
