Which port to use when connecting by FTP

Introduction

To upload or manage website files with an FTP program, you need the server, the username, the password and the connection port.

The most common port for a standard FTP connection is 21. There are also other connection types, such as FTPS and SFTP, which may use different settings.

Recommended port for FTP

For a standard FTP connection, use:

FTP port: 21

Typical connection details look like this:

Server: your-domain.com
Username: your FTP username
Password: your FTP password
Port: 21
Protocol: FTP

You can also use the hosting server name if that is what appears in your access details.

Difference between FTP, FTPS and SFTP

FTP

This is the classic file transfer protocol.

Protocol: FTP
Port: 21

FTPS

This is FTP with SSL or TLS encryption. In many clients it appears as Explicit FTP over TLS.

Protocol: FTPS
Typical port: 21

In most cases it still uses port 21, but the connection is encrypted.

SFTP

SFTP runs over SSH and is not the same as FTP.

Protocol: SFTP
Typical port: 22

You can only use it if your service has SSH or SFTP access enabled.

Quick FileZilla example

If you use FileZilla, a typical setup is:

1. Open File > Site Manager.
2. Create a new site.
3. In Host, enter your domain or hosting server.
4. In Protocol, choose FTP.
5. In Encryption, choose Explicit FTP over TLS if available.
6. In Logon Type, use Normal.
7. Enter your username and password.
8. In Port, enter 21.
9. Click Connect.

Common problems

Wrong username or password

Make sure you are using the correct FTP username. It is not always the same as the main control panel user.

The server does not connect

Check these points:

1. The domain points to the correct hosting account.
2. The port is correct.
3. The FTP server name is written correctly.
4. Your firewall or antivirus is not blocking the connection.

Error when using SFTP

If you try port 22 and it does not work, your plan may not have SSH or SFTP enabled.

You connect but do not see files

This may be caused by the connection mode. Try switching between active and passive mode. In most networks, passive mode is the most compatible option.

Useful tips

• Use FTP on port 21 if you only need to upload or download files.
• Use FTPS if your client supports it and you want encryption.
• Use SFTP on port 22 only if the service supports it.
• Do not share your FTP credentials with unauthorized third parties.
• If you need temporary access, create a dedicated FTP account.

Frequently asked questions

Which port should I use for FTP

The normal FTP port is 21.

Which port does SFTP use

Usually 22, as long as the service has SSH or SFTP access enabled.

Are FTP and SFTP the same

No. Both transfer files, but they use different protocols.

Can I use my domain as the FTP server

Yes. In many cases you can use your-domain.com or ftp.your-domain.com. If the domain does not point to the hosting account yet, use the server name from your access details.

Conclusion

To connect to your hosting account by FTP, the port you should normally use is 21.

If you want a more secure connection, you can try FTPS. If you need SFTP, remember that it usually uses port 22, but that access must be enabled on your service.
