About TCP/UDP Port Numbers
This common port numbers list covers well-known and frequently used TCP and UDP ports — from FTP on 21, SSH on 22 and HTTP on 80 to database ports like MySQL 3306, PostgreSQL 5432, Redis 6379 and MongoDB 27017, with over 120 entries in total. Each row shows the port number, its transport protocol (TCP, UDP or both), the service name, a one-line description and a usage category.
Categories organize the table by what you are doing: Web, Email, File Transfer, Remote Access, Database, Directory, Messaging/Chat, DNS, Networking, Media/VoIP and Game. Search works from either direction — type 3306 to identify a port you found in a netstat listing, or type SSH to find the port a service uses.
The list is rendered with the page itself, so it works without JavaScript and search happens instantly in your browser. Any port number copies to the clipboard in one click, ready for a firewall rule, a Docker port mapping or a connection string.
How to use TCP/UDP Port Numbers
- Search by port number or service name — for example 443, SSH or DNS.
- Filter by category to browse web, email, database, remote-access or gaming ports as a group.
- Read the protocol column to see whether the service runs over TCP, UDP or both.
- Click the copy button to grab the port number for your firewall rule or configuration.
