TLV

TLV is an acronym that can refer to several distinct concepts in technology and transportation. In computing and communications, TLV typically denotes a tag–length–value encoding. In aviation and travel, TLV is the IATA airport code assigned to Ben Gurion Airport, the main international gateway to Israel, located near Tel Aviv. The code is frequently used for flight schedules, baggage tags, and airline reservations.

Tag–Length–Value encoding is a simple data format in which information is grouped into triplets: a tag that identifies the type of data, a length field that specifies how many bytes comprise the value, and the value itself. TLV streams enable flexible, self-describing data and support parsing even when field order varies. The approach is widely used in standards and protocols, including ASN.1 BER/DER encodings and various NFC, smart card, and network protocols. Variants differ in how tags, lengths, and values are encoded, but the basic pattern remains the same.

Ben Gurion Airport, IATA TLV, is Israel's largest and busiest airport, serving international and domestic routes. It sits near Lod, southeast of central Tel Aviv. The facility is named after David Ben-Gurion, Israel's first prime minister, and functions as the principal gateway for international travelers entering and leaving Israel.
