Transport Layer protocols, such as the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), specify a source and destination port number in their packet headers. A port number is a 16-bit unsigned integer, thus ranging from 1 to 65535 (for TCP, port number 0 is reserved and can't be used. For UDP the source port is optional and a value of zero means no port)
