Quick answer: The fastest route is the Help button inside the Viator app (or “Help” at the top right of the website when signed in), which opens 24/7 chat tied to your booking. For urgent same-day problems you can also phone Viator — the US line is 1-888-680-1640, with local numbers listed on the Help page for other countries — but for “the guide is late” situations, call the operator’s number on your voucher first: they are the ones who can actually find the bus. Have your booking reference (starts with “BR-”) ready either way.

Top-Rated Sydney Tours & Experiences on Viator
Chat: the Default Route
In the app, open the booking and tap Help; on the website, sign in and click Help at the top right, then select the booking. Chat is available 24/7, and because it starts from the booking, the agent already sees the operator, date and policy. Typical response time is minutes. Say what you need in the first message — “Operator did not show at 9:00, no answer on the phone, requesting a refund” — and attach a screenshot if relevant. Agents can contact the operator, rebook you, or process a refund.

Phone: for Urgent, Same-Day Problems
Viator publishes country-specific phone numbers on its Help page; the US number is 1-888-680-1640 and support is 24/7. Phone is worth it when you are standing at a meeting point and the chat is not moving fast enough. Have the booking reference ready, and the operator’s phone number from the voucher, because the agent will try to call them too.
The Operator: Often the Right First Call
Every voucher carries the operator’s local phone number. For anything about the day itself — running late, which corner of the square, pickup time — the operator can fix it and Viator cannot. Viator support becomes the right contact when the operator is unreachable, when the tour did not take place, or when money is involved. Keep a note of the time you tried to call the operator; it helps a refund claim.

What to Have Ready
Booking reference (BR-…), the email used to book, the tour date and time, the operator name, a one-sentence description of the problem, and evidence: screenshots of the voucher and meeting point, call logs, photos. For refund follow-ups, the cancellation email. The more of this you paste in the first message, the fewer back-and-forths you will have.
Refunds and Escalation
Valid cancellations are refunded automatically; you do not need to contact anyone. If the operator cancelled or did not show, ask support for a full refund the same day — it is normally granted quickly. If a refund has not reached your card after 10 business days, ask support for the refund transaction ID and give it to your bank. If you feel a case was handled wrongly, reply on the same chat thread asking for it to be reviewed by a supervisor, and state the outcome you want (refund, partial refund, rebooking). Keep it factual. As a last resort, a card chargeback exists for services not provided, but use it only after Viator has declined — see our guide to refunds and chargebacks.

Before Booking: Questions for the Operator
Most listings have a “Contact the operator” link. Use it for accessibility (steps, wheelchair, strollers), pickup from a specific hotel, dietary needs on food tours, or whether children under a certain age are accepted. Replies usually come within a day. This avoids most of the on-the-day problems above.
Common Problems, Quick Answers
Voucher not showing in app: sign in with the exact booking email; use “Find my booking” from the confirmation email. Wrong date booked: if inside the free window, cancel and rebook (how); otherwise ask the operator. Charged twice: one is usually a pending authorisation that drops off in days; if both settle, support refunds the duplicate. Weather: see weather cancellations and no-shows. Policy questions: cancellation policy explained.

Frequently Asked Questions
What is Viator’s customer service phone number?
In the US, 1-888-680-1640, available 24/7. Other countries’ numbers are listed on Viator’s Help page. Chat from inside the app or website is usually faster.
Does Viator have 24/7 support?
Yes. Chat and phone support are available around the clock, and both can contact the operator, rebook you or issue refunds.
Should I contact Viator or the tour operator?
For on-the-day logistics (late guide, meeting point), call the operator using the number on your voucher. For no-shows, refunds and policy issues, contact Viator.
How do I get a refund if the tour didn’t happen?
Contact Viator support the same day with your booking reference and a description of what happened. Operator no-shows are refunded in full.
Can I ask the operator a question before booking?
Yes. Most listings include a “Contact the operator” link; replies typically arrive within a day.
What if Viator refuses my refund?
Ask on the same thread for a supervisor review, stating the facts and the outcome you want. If the service was genuinely not provided and Viator still declines, a card chargeback is a last resort.
