How to Say 'Let Us Know' in Italian: Facci, Fateci, and Ci Faccia Sapere
Learn to ask one person, a group, or a formal contact to keep you updated in Italian, using facci sapere, fateci sapere, and ci faccia sapere.

Italian makes a small but important distinction when you ask someone to let you know: the verb ending shows whether you are speaking to one person or several, and the pronoun ci marks who receives the information. The three most useful patterns are facci sapere (to one person you know well), fateci sapere (to a group you know well), and ci faccia sapere (to one person in a formal context). This lesson shows how to use them for schedule updates, appointments, and other everyday requests.
By the end, you can…
- ask one person or a group to let me know using facci sapere and fateci sapere.
- use the formal ci faccia sapere with a person I address politely.
- distinguish who is being asked from who receives the information.
Listen once. Try it slowly. Then say it without looking.

Facci sapere.
Let us know.
FAHT-chee sah-PEH-reh
Address one person informally. Facci combines the singular command fa’ with ci (us); ci identifies who receives the information, not how many people you are addressing.
Fateci sapere.
Let us know.
FAH-teh-chee sah-PEH-reh
Use with two or more people you address informally. The ending -te shows several people are being asked.
Ci faccia sapere.
Let us know.
chee FAHT-chah sah-PEH-reh
Use with one person you address formally, such as a receptionist, a professor, or a new professional contact.
Fateci sapere se l'orario cambia.
Let us know if the schedule changes.
FAH-teh-chee sah-PEH-reh seh loh-RAH-ryoh KAHM-byah
A concrete request addressed to a group. The pronoun ci means 'us' and stays attached to the imperative fate.
Ci faccia sapere quando è confermato.
Let us know when it is confirmed.
chee FAHT-chah sah-PEH-reh KWAHN-doh eh kohn-fehr-MAH-toh
A polite request to one person. Use it when you want an update about a booking, appointment, or arrangement.

Useful pattern
The core pattern is an imperative form of fare plus ci plus sapere. Ci means 'us' and attaches to the imperative: facci, fateci, ci faccia. The ending of the imperative tells you how many people are addressed: facci is singular informal, fateci is plural informal, and ci faccia is singular formal. The verb sapere stays in the infinitive. Examples: Facci sapere se arrivi tardi. Fateci sapere se l'orario cambia. Ci faccia sapere quando è confermato. In each case, ci marks the people who receive the information, while the imperative ending marks the person or people being asked.
When to use it
Use facci sapere with one friend, family member, or close colleague. Use fateci sapere when you are writing or speaking to a group, such as a team, a couple, or several staff members. Use ci faccia sapere when you address one person politely, for example a hotel receptionist, a doctor's office, or a professor. If you are not sure whether to be formal, ci faccia sapere is the safer choice with strangers and professionals. For a group you address formally, Italian often prefers a different structure, such as Vi chiediamo di farci sapere, because ci faccia is singular. These patterns are common throughout Italy; regional usage does not change the basic distinction.
Listen to each line, then take one part and reply out loud.
Ciao Marco, facci sapere se la riunione di domani è confermata.
Hi Marco, let us know if tomorrow's meeting is confirmed.CHAH-oh MAR-koh, FAHT-chee sah-PEH-reh seh lah ree-oo-NYOH-neh dee doh-MAH-nee eh kohn-fehr-MAH-tahCerto, appena ho notizie vi scrivo.
Of course, as soon as I have news I'll write to you.CHEHR-toh, ahp-PEH-nah oh noh-TEE-tsyeh vee SKREE-vohGrazie. E facci sapere anche se cambia l'orario.
Thanks. And let us know also if the time changes.GRAH-tsyeh. eh FAHT-chee sah-PEH-reh AHN-keh seh KAHM-byah loh-RAH-ryohVa bene, ci sentiamo domani mattina.
All right, we'll be in touch tomorrow morning.vah BEH-neh, chee sehn-TYAH-moh doh-MAH-nee maht-TEE-nahA little context goes a long way
Italian has both informal and formal ways to address people. Facci and fateci are for people you call tu; ci faccia is for someone you address with Lei. In many workplaces, colleagues use informal forms, but with clients, officials, or people you have just met, the formal ci faccia sapere is more appropriate. When writing to a group formally, avoid ci faccia and use a plural polite structure such as Vi chiediamo di farci sapere.
One thing to watch for
Using fateci sapere when speaking to only one person, or using facci sapere with a group.
Try this instead: Match the imperative ending to the number of people addressed. To one friend: Facci sapere se l'orario cambia. To several friends: Fateci sapere se l'orario cambia. To one person formally: Ci faccia sapere se l'orario cambia.
Your turn
Try answering out loud before checking a possible answer.
1You are writing to one colleague you know well. Ask them to let you know if the schedule changes.
Show a sample answer
Facci sapere se l'orario cambia.
Facci is the informal singular imperative with ci attached, so it addresses one person you know well. Fateci sapere would address several people, and Ci faccia sapere would be formal.
2You are speaking to a hotel receptionist. Ask politely to be told when the room is ready.
Show a sample answer
Ci faccia sapere quando la camera è pronta.
Ci faccia sapere is the formal singular form, appropriate for one person you address with Lei. Facci sapere would be too informal, and fateci sapere would address several people.
3You are emailing a small team you know well. Ask them to let you know if the appointment time changes.
Show a sample answer
Fateci sapere se l'orario dell'appuntamento cambia.
Fateci sapere addresses two or more people informally. If you were writing to one person formally, you would use Ci faccia sapere instead.
Use facci sapere for one person you know, fateci sapere for a group you know, and ci faccia sapere for one person you address formally. The ending shows who is asked; ci shows that we receive the information.
