Usually its port 21. Though alot of people fail to realise that just because that's the default setting doesn't mean you cant change it.
FTP servers listen on port 21. The data transfers happen on a different port, which is usually done in passive mode, on a port above 1024.

How does the TCP handle the issue of multiplexing?
tcp at the transport layer handles multiplexing with address called port number of service access points (SAP).For every service that is using TCP at one particular machine is assigned a port nuber or SAP. When the datagram is being sent the TCP software appends the SAP or the port number of the source and the destination service. At the reciving end the TCP software again extracts the destination SAP and forwards the datagram to the appropiate service. Now if there are multiple source services and multilple destination services each with a unique ID, the TCP software can distinguish between different datagram belonging to different services. Thus with the use of SAP or port numbers TCP can handle multiplexing....
