The city is colloquially known by the local people as '' which is the Malay word for '(the) Port'. However, the exact area that the name refers to may differ in conversational context: apart from referring to the same areas as the city's official jurisdiction, 'Bandar' may also refer exclusively to the Pusat Bandar (literally 'City Centre') area of the capital to distinguish from other named areas within the city, whereby they were not part of the capital prior to 2007. Meanwhile, it may sometimes extend beyond the city's proper area, encompassing its surrounding urbanised areas and even to the extent of covering the whole of Brunei-Muara District. The latter usage is common by residents who live outside of the district.
