This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The (TCP) and the (UDP) only need one for , bidirectional traffic. 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,[1] 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.

Cell Description
Yes Described protocol is assigned by IANA for this port, and is: standardized, specified, or widely used for such.
Unofficial Described protocol is not assigned by IANA for this port, but is: standardized, specified, or widely used for such.
Assigned Described protocol is assigned by IANA for this port,[2] but is not: standardized, specified, or widely used for such.
No Described protocol is not assigned by IANA for this port, standardized, specified, or widely used for such.
Reserved Port is reserved by IANA,[2] generally to prevent collision having its previous use removed.[3][4] The port number may be available for assignment upon request to IANA.[3]

Well-known ports

The port numbers in the range from 0 to 1023 (0 to 210 − 1) are the well-known ports or system ports.[3] 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.[5]

Note

  1. TCP port 465 was originally assigned to allow the use of SMTP over SSL (SMTPS), but practical concerns meant that it was left unused and according to the registration rules at that time was subsequently revoked and eventually re-assigned for use by Cisco's URD protocol. Subsequently, port 587 was assigned as the SMTP submission port, but was initially in plaintext, with encryption eventually provided years later by the STARTTLS extension. At the same time, the subsequent adoption of the usage of 465 as an SSL-enabled SMTP submission port, even though the original registration did not envision that usage and despite the fact that it was registered to another service has endured. Subsequently, RFC 8314, in a special exemption to the normal assignment process as defined by RFC 6335, acknowledges the de-facto situation and not only designates message submission over implicit TLS as an 'alternate usage assignment' but establishes this as the preferred method and calls for transition away from port 587 and STARTTLS.
  2. Deployment typically occurs only directly over UDP, but other underlying protocol layers which meet the requirements described in the specification are possible.
