List of TCP and UDP port numbers

Return to Internet topics, Networking topics

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 (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.<ref name=“IANA”>

</ref> 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

Legend of TCP and UDP protocol table cells for port numbers
Cell	Description
	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,<ref name=“IANA”/> but may not be standardized, specified or widely used for such.
	Port number may use the protocol conditionally only, or alternate its use (fallback if the other protocol fails).
	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.<ref name=“rfc6335”/>
	Protocol is reserved by IANA<ref name=“IANA”/> for future use or special purposes.<ref name=“rfc6335”/><ref name=“rfc7605”> </ref> See “N/A” above.
	Protocol use by port number is unknown or unverified.

Well-known ports

<!– Well-known ports and similar redirect here. –>

The port numbers in the range from 0 to 1023 (0 to 2¹⁰ − 1) are the well-known ports or system ports.<ref name=“rfc6335”>

</ref> 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.<ref name=“man-5-services-die.net”>

. “… Port numbers below 1024 (so-called “low numbered” ports) can only be bound to by root … Well-known port numbers specified by the IANA are normally located in this root-only space. …”</ref>

<!– In this table, the Port number, TCP and UDP columns are lined up

    using spaces as padding. The reason for this is for wiki markup readability only.

Registered ports

The range of port numbers from 1024 to 49151 (2¹⁰ to 2¹⁴ + 2¹⁵ − 1) are the registered ports. They are assigned by IANA for specific service upon application by a requesting entity.<ref name=IANA /> On most systems, registered ports can be used without superuser privileges.

<!– In this table, the Port number, TCP and UDP columns are lined up

    using spaces as padding. This is for wiki markup readability only.
