How to Say "confirmed" in Spanish
The most common Spanish word for “confirmed” is “confirmado” — use 'confirmado' as an adjective when referring to the status of something, like a reservation, appointment, or flight, indicating it is set or finalized..
confirmado
kon-feer-MAH-doh/koɱfirˈmaðo/

Examples
El vuelo a Madrid está confirmado.
The flight to Madrid is confirmed.
La noticia es falsa. No está confirmado.
The news is false. It is not verified.

We have the confirmed attendance of 50 people.

Adjective Agreement
As an adjective, 'confirmado' must change its ending to match the thing it describes. Use 'confirmada' for feminine things (la reserva confirmada) and add an 's' for plurals (los vuelos confirmados).
Using 'Estar'
When describing a temporary state or status, use 'estar'. Since something being 'confirmed' is a state, you almost always say 'está confirmado' (it is confirmed).
The Perfect Tenses
'Confirmado' is the form you use after the verb 'haber' (to have) to create tenses like 'he confirmado' (I have confirmed) or 'había confirmado' (I had confirmed).
Invariable Form
Unlike when it's an adjective, when 'confirmado' is used right after 'haber' to form a perfect tense, it NEVER changes its ending. It always stays 'confirmado,' regardless of who did the confirming.
Using 'Ser' for Status
Mistake: “El vuelo es confirmado.”
Correction: El vuelo está confirmado. (Use 'estar' because being confirmed is a current status, not a permanent characteristic.)
Changing the Ending with 'Haber'
Mistake: “Hemos confirmadas las reservas. (Incorrect agreement with 'haber'.)”
Correction: Hemos confirmado las reservas. (The participle is fixed when used with 'haber'.)
