FTP Server Return and Error Codes Table Cheat Sheet

This is the FTP Server Return and Error Codes Table Cheat Sheet. The FTP server return codes always contain three digits, and each number has a special definition. The first digit will tell you if a server response is good, bad or incomplete.

Knowing fully well the meaning of the FTP Server Return Codes will help you know if an FTP connection, upload and download is going smoothly or not. It will also certainly give you a notification if something needs to be fixed or changed from the end of the server or the FTP client.
