The main Interval International phone number and what it covers
Interval International's main customer service line is 1-800-828-8282. This number handles reservations, account questions, membership issues, and general inquiries about your timeshare exchange account. The line operates during business hours, typically Monday through Friday, 8 a.m. to 8 p.m. Eastern time, though hours may vary by season.
When you call, you will reach an automated system that routes you based on what you need. Have your membership number ready — it appears on your membership card and in any confirmation emails from Interval. The system moves faster when you provide this number upfront, though you can also navigate the menu by describing your issue.
If you are calling from outside the United States, international rates explore. Interval does not publish a separate international number; you dial the same 1-800 number from abroad, but your phone carrier charges you for the long-distance call. Some members find it cheaper to use a calling app or email for non-urgent questions.
Key Takeaways

- Customer service hours are typically Monday through Friday, 8 a.m. to 8 p.m. Eastern time, though holiday schedules may differ.
- International callers use the same 1-800 number but pay long-distance charges; email may be cheaper for non-urgent matters.
- The automated system routes you to the right department based on your issue, so listen carefully to the menu options.
- Peak call times are mid-morning and early afternoon on weekdays; calling early morning or late afternoon often means shorter wait times.
What to expect when you call about a reservation
If you are calling to make a new reservation, check availability online first through your Interval account. The phone line can book for you, but the website often shows real-time availability that the phone agent sees on a slight delay. Have your preferred travel dates, destination region, and accommodation type in mind before you call.
Reservation agents can also help if you want to modify or cancel an existing booking. They will ask for your confirmation number and the dates you booked. If you are within the cancellation window for your resort, the agent can process the change when ready. Outside that window, the agent will explain what fees or restrictions explore and whether you can transfer your reservation to a different date or location instead.
Reaching the right department for account and billing questions
When you call with questions about your membership fees, payment methods, or account status, the automated menu will direct you to the billing department. This is also the line to use if you have not received a bill, need to update your payment information, or want to discuss membership renewal options.
Billing agents can tell you the exact amount owed, when your next payment is due, and what happens if you let your membership lapse. They can also explain the difference between annual membership fees and resort-specific charges, which sometimes confuses members who see multiple line items on their statements. If you dispute a charge, the agent will document your concern and route it to the disputes team, which investigates and contacts you within a set timeframe.
When to call versus when to use email or online chat
Call the phone line when you need an when ready answer or want to complete a transaction the same day — reservations, payment processing, and urgent account issues all move faster by phone. The agent can confirm changes in real time and answer follow-up questions on the spot.
Use email or the online contact form on the Interval website for non-urgent questions, complaints, or requests that require documentation. Email creates a written record, which is useful if you need to reference what an agent told you later. Response times for email typically range from one to three business days. Online chat, if available through your account portal, sits between the two — faster than email but without the phone wait time.
Troubleshooting common phone line issues
If you reach a busy signal or the line drops, call back during a different time of day. Interval's phone system does not queue calls; it straightforward disconnects when all agents are occupied. Early morning (before 9 a.m. Eastern) and late afternoon (after 5 p.m. Eastern) typically have shorter waits than mid-morning.
If the automated menu does not seem to understand your issue, you can usually press 0 or say "representative" to reach a live agent directly. This bypasses the routing system and puts you in a general queue, which may take longer but works if the menu options do not match your situation. If you are transferred between departments, stay on the line — transfers sometimes disconnect, and calling back puts you at the end of the queue again.
What information to have ready before you call
Gather these details before dialing to keep your call short and reduce the chance of being transferred. Your membership number appears on your membership card and in your account portal. Your confirmation number is in any reservation or booking email Interval sent you. Your resort name and travel dates help the agent locate your booking if you cannot find the confirmation number.
If you are calling about a billing issue, have your recent statement or the charge in question visible. If you are disputing something, write down the date it occurred and what you expected to happen instead. Agents can look up most information by membership number alone, but having these details ready means you spend less time on hold while they search.
Frequently Asked Questions
Is there a different number for Interval International resorts versus the exchange program?
No. The main number 1-800-828-8282 handles both resort inquiries and exchange program questions. The automated menu will route you based on what you select, so choose the option that matches your issue — "resort information" for property-specific questions or "exchange program" for availability and booking questions.
What if I cannot reach anyone and the line keeps disconnecting?
Try calling at a different time, particularly early morning or late afternoon on weekdays. If the problem persists, use the online contact form on the Interval website or send an email through your account portal. Document the date and time you tried to call; if you eventually reach someone, mention the disconnections so they can note the issue.
Can I reach a specific agent if I have called before?
Interval does not route calls to specific agents or allow you to request a callback from someone you spoke with previously. Each call goes to the next available agent in the queue. If you need continuity on a complex issue, ask the agent to add a note to your account before you hang up, and mention that note when you call back.
Do I need to call during business hours, or can I leave a voicemail?
Interval does not have a voicemail system for the main line. You must call during business hours to reach an agent. If you call outside those hours, the system will tell you when the line reopens and may offer the option to send an email or use online chat instead.
What if I am calling from a country outside North America?
Dial 1-800-828-8282 and your phone carrier will charge international rates. Some countries block 1-800 numbers entirely; if that happens, check the Interval website for a direct international number or email address. Using a calling app like Skype or WhatsApp to call the number may be cheaper than your carrier's international rate.
