List of TCP and UDP port numbers

This article contains dynamic lists that may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

This is a list of TCP and UDP port numbers used by protocols of the application layer of the Internet protocol suite for the establishment of host-to-host connectivity.

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. 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.

The Internet Assigned Numbers Authority (IANA) 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

  Official: Port is registered with IANA for the application.

  Unofficial: Port is not registered with IANA for the application.

  Multiple use: Multiple applications are known to use this port.

Legend of TCP and UDP protocol table cells for port numbers

Cell	Description
Yes	Described protocol is standardized, specified or widely used for the port number.
No	Described protocol is not standardized, specified or widely used for the port number.
Assigned	Port number is assigned by IANA for protocol use, but may not be standardized, specified or widely used for such.
Yes/No	Port number may use the protocol conditionally only, or alternate its use (fallback if the other protocol fails).
Port 22	Port number doesn't use the protocol, but may use the protocol on another specified port (e.g., port 22).
—	Not applicable or currently unassigned port number. For unassigned ports, the port number may be available for assignment upon requesting assignment by IANA.
Reserved	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

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

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.

Registered ports

This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by adding missing items with reliable sources.

The range of port numbers from 1024 to 49151 are the registered ports. They are assigned by IANA for specific service upon application by a requesting entity. On most systems, registered ports can be used without superuser privileges.
