French Phrase
C'est quoi mon numéro de compte ?
Meaning
You are asking someone (typically a bank representative or a customer‑service chatbot) to tell you the number that identifies your bank account. It’s a direct, informal request for personal banking information.
When to use
Use this phrase when you are on the phone, in a chat, or face‑to‑face with a bank employee and need to retrieve your account number quickly. It works best in casual or semi‑formal settings; in a very formal context you might prefer "Quel est mon numéro de compte ?".

C'est + quoi
In spoken French, "C'est quoi" is an informal way to ask "What is..."; the more formal version is "Quel est...".
Possessive adjective (mon)
Use "mon" before masculine singular nouns (or before a vowel/h‑muet) to mean "my".
Noun‑of‑noun construction (numéro de compte)
The preposition "de" links two nouns, indicating that the second noun specifies the type of the first ("account number").

✕Common Mistakes
C'est quel mon numéro de compte ?
"Quel" is an adjective and must agree with the noun; after "c'est" you need the interrogative pronoun "quoi".
C'est quoi mon numéro du compte ?
The correct preposition is "de" (noun‑of‑noun), not "du" which would mean "of the" and changes the meaning.
C'est quoi mon numéro de compte
In written French, a question mark is required at the end of a direct question.

Cultural Tip
French distinguishes between informal and formal registers. "C'est quoi..." is perfectly acceptable in everyday conversation or with a friendly bank clerk, but in written correspondence or when speaking to a senior representative, opt for the more formal "Quel est...". Also, never share your account number in public spaces; always ensure you are speaking to a verified representative.
