Marriott's main customer service number and what it handles

Marriott International's primary customer service line is 1-800-721-6564. This number connects you to representatives who handle reservations, changes to existing bookings, loyalty program questions, and general inquiries about Marriott properties worldwide.

Wait times vary by time of day and season. Calling early morning (before 9 a.m. in your time zone) or mid-afternoon typically means shorter holds than calling during peak travel booking hours. The line operates seven days a week.

If you are calling about a specific property — a particular Marriott, Ritz-Carlton, or W Hotel — you can also call that hotel's direct number. The main line can transfer you, but calling the property directly often reaches someone who knows your reservation when ready.

Key Takeaways

  • Marriott's main customer service number is 1-800-721-6564 and handles reservations, booking changes, and loyalty program questions.
  • Calling the specific hotel property directly is often faster for questions about your stay or room-specific issues.
  • Different departments handle lost items, billing disputes, and damage claims — the main line can route you to the right one.
  • Marriott Bonvoy members can reach loyalty program support through the same main number or through the Bonvoy app.

Numbers for specific situations and departments

If you lost an item at a Marriott property, call the hotel directly first — most lost and found inquiries are handled by the front desk or housekeeping at that location. If you cannot reach them or need corporate information, the main number can connect you to the lost items department.

For billing disputes or charges you do not recognize, the main line routes you to the billing department. Have your confirmation number and the dates of your stay ready. This department can also help if you were charged for a cancellation you believe you made within the cancellation window.

Marriott Bonvoy members with questions about points, redemptions, elite status, or account issues can call the loyalty program line at 1-800-228-9290. This line is dedicated to Bonvoy members and typically has shorter waits than the general customer service line.

How to find the direct number for a specific hotel

Every Marriott property has its own phone number. You can find it by searching the hotel name on Marriott.com, looking at your confirmation email, or calling 1-800-721-6564 and asking for the property's direct line.

Calling the property directly is useful for questions the main line cannot answer quickly: whether a room upgrade is available, what time breakfast ends, whether the fitness center is open, or if they can hold a late arrival. Front desk staff at the property can also sometimes resolve billing or booking issues faster than the central line.

Using the Marriott app and website instead of calling

The Marriott Bonvoy app lets you manage reservations, check in early, request late checkout, and message the hotel directly without calling. For many routine changes — adding a guest, changing your room type preference, or requesting a high floor — the app is faster than waiting on hold.

The website (Marriott.com) also allows you to modify reservations, view your confirmation, and access your Bonvoy account. If you need to cancel or make a significant change, you can often do it online without calling, though the phone line is still the fastest way to speak to someone if something goes wrong.

International calls and numbers outside the United States

If you are calling from outside the United States, the 1-800 number will not work. Instead, search for "Marriott customer service" plus your country name, or call the specific hotel property directly — every Marriott has a local phone number.

Marriott also operates regional customer service lines in many countries. The main website lists these by region. Calling a local number is usually cheaper than calling the U.S. line internationally and avoids long-distance charges.

What to have ready before you call

Before calling, gather your confirmation number (found in your booking email), the dates of your stay, and the property name. If you are calling about a billing issue, have your credit card or payment method information available. For loyalty program questions, have your Bonvoy membership number ready.

If you are calling about a problem — a charge you dispute, a room issue, or a service failure — write down what happened and when. This helps the representative understand the situation quickly and makes it easier for them to escalate if needed.

Frequently Asked Questions

Can I reach a person when ready or do I have to wait on hold?

You will typically wait on hold, though the wait time depends on call volume. The system usually tells you the estimated wait when you call. Calling outside peak hours (early morning or late evening) reduces wait time. Some issues can be resolved through the app or website without calling at all.

What if I need to reach Marriott about a reservation I made through a travel agent or third-party site?

Call the main Marriott line with your confirmation number. Marriott can look up reservations made through any booking channel. If the issue involves a refund or dispute with the third-party site, Marriott can explain what they can and cannot do, but you may need to contact the site directly for refund processing.

Is there a number for corporate or business inquiries?

The main customer service line handles most business inquiries. For large group bookings, meeting space, or corporate accounts, ask to be transferred to the group sales department. For franchise or partnership inquiries, visit Marriott.com and look for the "Careers" or "Franchise" section, which lists the appropriate contact.

What if I am calling about a stay that already happened?

Call the main line with your confirmation number and the dates of your past stay. Representatives can look up your reservation history and help with billing questions, missing charges, or complaints about your experience. They can also help you file a formal complaint if something went wrong during your stay.

Can I schedule a callback instead of waiting on hold?

Some Marriott lines offer callback options during high-volume periods. When you call, listen for the option to request a callback, and a representative will call you back within the estimated wait time. This is not always available, but it is worth checking when you reach the automated system.
