Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features, encompassing the United States and its territories; the Compact of Free Association, associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Area Codes 937 And 326
Area codes 937 and 326 are telephone area codes in the North American Numbering Plan (NANP) assigned to a numbering plan area (NPA) that encompasses much of the southwestern part of the U.S. state of Ohio, including Dayton and Springfield. Area code 937 was established in September 1996, in a split of area code 513. Area code 326 was added to the numbering plan area to form an overlay complex in March 2020. History Area code 937 was created in a split of Ohio's original NPA for the southwestern part of the state ( area code 513) on September 28, 1996. At the time, literature promoting the new area code took advantage of the fact that the digits of ''937'' spell out "YES" on a standard telephone keypad. As of April 2018, projections by the North American Numbering Plan Administrator expected that telephone exchanges ("central office codes") would be exhausted for area code 937 by the third quarter of 2020. For mitigation, on July 3, 2018, area code 326 was planned to ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
