The Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use port numbers.

They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.

Similarly many of the official assignments refer to protocols that were never or are no longer in common use.

This article lists port numbers and their associated protocols that have experienced significant uptake.
