✕Common Mistakes

  • C'est quel mon numéro de chambre ?

    Using "quel" directly after "c'est" is ungrammatical; you must say "Quel est mon numéro de chambre ?" instead of "C'est quel mon numéro de chambre ?"

  • C'est quoi ma numéro de chambre ?

    "Numéro" is masculine, so the possessive must be "mon" not "ma".

  • C'est quoi mon numéro de la chambre ?

    The correct construction is "numéro de chambre" (room number), not "numéro de la chambre" which would mean "the number of the room" in a different context.

↔Alternatives

    What is my room number?

  • Pouvez‑vous me dire mon numéro de chambre ?

    Could you tell me my room number?

  • J’ai oublié mon numéro de chambre, pouvez‑vous m’aider ?

    I forgot my room number, can you help me?

Cultural Tip

In French hotels, staff often address guests with "Monsieur" or "Madame" followed by the room number. While "C'est quoi…" is perfectly understandable, the more formal "Quel est…" is preferred in upscale establishments. Also, note that French rooms are usually numbered by floor (e.g., 215 = 2nd floor, room 15).
