List of TCP and UDP port numbers


This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications.
The Transmission Control Protocol and the User Datagram Protocol needed only one port for full-duplex, bidirectional traffic. The Stream Control Transmission Protocol and the Datagram Congestion Control Protocol also use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist.
The Internet Assigned Numbers Authority is responsible for maintaining the official assignments of port numbers for specific uses. However, many unofficial uses of both well-known and registered port numbers occur in practice. 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.

Table legend

CellDescription
Described protocol is standardized, specified or widely used for the port number.
Described protocol is not standardized, specified or widely used for the port number.
Port number is assigned by IANA for protocol use, but may not be standardized, specified or widely used for such.
Port number may use the protocol conditionally only, or alternate its use.
Port number doesn't use the protocol, but may use the protocol on another specified port.
Not applicable or currently unassigned port number. For unassigned ports, the port number may be available for assignment upon requesting assignment by IANA.
Protocol is reserved by IANA for future use or special purposes. See "N/A" above.
Protocol use by port number is unknown or unverified.

Well-known ports

The port numbers in the range from 0 to 1023 are the well-known ports or system ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.
