An email address ending in .cz is from the Czech Republic. The .cz domain is the country-code top-level domain for Czech Republic addresses, and examples of native Czech email formats use names like [email protected].

Quick note

  • @something.cz usually means the domain is registered in or associated with the Czech Republic.
  • It does not guarantee the sender is physically located there; email addresses can be spoofed or used by anyone anywhere.

Safety tip

If you’re checking whether a .cz email is legitimate, look at the full sender details and message content, not just the ending. Phishing and scam emails can use country domains too.
