757

757 is a number used to refer to several different topics. The most widely recognized is the Boeing 757, a twin-engine, narrow-body jet airliner built by Boeing Commercial Airplanes. It first flew in 1982 and entered service in 1983. Designed for medium-range routes, the aircraft typically accommodates around 200 passengers, depending on configuration. The 757 uses two high-bypass turbofan engines, offered by Pratt & Whitney or Rolls-Royce, and it emphasizes efficiency and performance on less-than-long-haul flights. Production continued through the 1980s and 1990s and ended in 2004. A range of passenger and freighter variants was developed from the 757-200 airframe, and many airframes remain in service in cargo, VIP, and special configurations after their original passenger service life.

757 also denotes an area code in the North American Numbering Plan. It covers the southeastern portion of Virginia and the northeastern part of North Carolina, including cities such as Norfolk, Virginia Beach, Chesapeake, Newport News, and Hampton. The 757 area code was created in 1953 by splitting it from the 804 area code, and it is associated with the Hampton Roads region.

In mathematics, 757 is a prime number. It is the natural number that follows 756 and precedes 758, having no positive divisors other than 1 and itself. Beyond these uses, 757 may appear in various domain-specific identifiers, codes, or model numbers in different industries.
