"A custom house or customs house was a building housing the offices for the government officials who processed the paperwork associated with importing and exporting goods into and out of a country. [...] The custom house was typically located in a seaport or in a city on a major river, with access to the ocean. [...] Due to advances in electronic information systems, the increased volume of international trade, and the introduction of air travel, the term ""custom house"" is now often an historical anachronism."
