What port does SQL Server use?
By default, named instances (including SQL Server Express) use dynamic ports. means each time Database Engine starts, it identifies an available port and uses that port number. If the named instance is the only instance of the Database Engine installed, it will probably use TCP port 1433. If other instances of the Database Engine are installed, it will probably use a different TCP port. Because the port selected might change every time that the Database Engine is started, it's difficult to configure the firewall to enable access to the correct port number. If a firewall is used, we recommend reconfiguring the Database Engine to use the same port number every time. A fixed port or a static port is recommended. For more information, see Configure a Server to Listen on a Specific TCP Port (SQL Server Configuration Manager).
