Costco Travel Customer Service: Phone Numbers, Hours, and What Actually Works in 2026

This is an independent, informational guide. It is not affiliated with, endorsed by, or sponsored by Costco Wholesale Corporation or Costco Travel. Contact details below were verified directly against Costco Travel’s official contact page in June 2026 — always cross-check at costcotravel.com before relying on a number you found somewhere else online.

Costco Travel’s main customer service number for bookings and trip planning is 1-866-921-7925 (Monday–Friday, 5 a.m.–7 p.m. PT; Saturday–Sunday, 6 a.m.–5 p.m. PT). If you’re already on your trip and something’s gone wrong, call 1-866-317-4711 instead. There’s no public live chat and no general customer service email address — support runs through phone, a self-service Help Center, and a handful of task-specific online forms.

If you searched for “Costco Travel customer service,” hoping for a fast, accurate answer rather than a wall of recycled numbers, here’s everything broken down clearly.

The Actual Costco Travel Customer Service Phone Numbers

Costco Travel splits its phone support by what stage of the trip you’re in, not just one general line:

• Reservations / planning a trip: 1-866-921-7925 — Monday–Friday 5 a.m.–7 p.m. PT, Saturday–Sunday 6 a.m.–5 p.m. PT
• While traveling (something’s gone wrong mid-trip):
  • From the U.S. or Canada: 1-866-317-4711
  • From Europe, the Cook Islands, Fiji, or Tahiti: 001-1-866-317-4711
  • From Costa Rica or Mexico: 00-1-866-317-4711
  • From the Caribbean: 1-1-866-317-4711
• Travel insurance questions: 1-844-246-8470

A heads-up worth flagging: Costco’s general customerservice.costco.com help page lists a different number, 1-877-849-2730, for Costco Travel. That number may still connect you somewhere useful, but it doesn’t match what’s currently posted on Costco Travel’s own official contact page. When two Costco-owned pages disagree, go with the one published directly by the department you’re trying to reach — in this case, 1-866-921-7925 from costcotravel.com itself.

Costco Travel Customer Service Hours

Phone support runs:

• Monday–Friday: 5 a.m.–7 p.m. Pacific Time
• Saturday–Sunday: 6 a.m.–5 p.m. Pacific Time

The call center closes entirely on New Year’s Day, Easter Sunday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day — though you can still book online on those days, since the website itself doesn’t shut down.

Does Costco Travel Have Live Chat?

No — at least not as a publicly listed option. Costco Travel’s official contact page offers phone, mail, an online Help Center of self-service articles, and a few specific web forms (for cruise credits, post-trip claims, and general site feedback), but no chat widget. If you come across a site claiming to offer “Costco Travel live chat support,” treat it with suspicion — see the scam-number warning below.

Costco Travel Customer Service Email Address

There isn’t one published for general inquiries. Costco Travel routes most written contact through structured web forms instead of email — there’s a Post-Trip Inquiry form for issues after you’ve returned, a cruise-credit form, a cruise payment-request form, and a website feedback survey. If you need something in writing, those forms (or postal mail) are the closest official equivalent:

Costco Travel, P.O. Box 34404, Seattle, WA 98124-9775

You may see “info@costcotravel.com” floating around on third-party complaint sites. It isn’t listed anywhere on Costco Travel’s own official pages, so don’t treat it as confirmed — stick to the phone numbers and forms above.

Costco Travel Rental Car Customer Service

Rental cars go through the same main number, with a specific menu option: call 1-866-921-7925 and select option 1. A few things specific to rentals are worth knowing before you call:

• You need an active Costco membership to book, and the primary driver has to show their membership card at pickup — the discount doesn’t apply without it.
• Drivers under 25 can’t book rental cars online; they have to call and book by phone instead, through the same number and option.
• Specialty vehicles like pickup trucks also have to be booked by phone rather than online.
• For problems with the car itself once you’re driving it (breakdowns, accidents, lockouts), you’ll typically deal with the rental company directly — Avis, Budget, Alamo, or Enterprise, depending on who you booked through — since they’re the ones actually operating the vehicle. Read more

How to Contact Costco Travel After a Trip or to File a Complaint

If something went wrong during travel and you’re dealing with it after the fact rather than in the moment, Costco Travel’s official channel is its Post-Trip Inquiry form (“Open a Claim” on the Contact Us page), not the general reservations line.

That routes your case to whoever handles post-trip issues rather than someone focused on new bookings. For billing disputes specifically, be ready with your reservation confirmation number, dates, and a clear timeline — multiple reviewers report that vague complaints take longer to resolve than ones with specifics attached.

What Costco Travel Customer Service Reviews Actually Say

Public reviews on sites like Trustpilot and PissedConsumer paint a mixed picture, and it’s worth knowing the shape of that before you call.

On the negative end, recurring themes include billing disputes that took weeks to resolve, missed airport transfers with no reimbursement offered on the spot, and slow follow-up once an issue got escalated past the first phone agent.

PissedConsumer’s own aggregated review data (self-reported by site visitors, not published by Costco) puts Costco Travel’s average rating around 2 out of 5 across several hundred reviews — though review-aggregator scores like this tend to skew toward people who had a bad enough experience to go looking for a place to complain, so treat it as directional rather than a precise satisfaction rate.

On the positive end, plenty of reviewers describe individual agents going well out of their way — helping arrange a tow after losing rental car keys abroad, or sticking with a customer through a credit-limit issue until a booking went through. The pattern that emerges across reviews is less “the company is bad” and more “results depend heavily on which agent picks up and how clearly you explain the problem” — which is fairly typical for large call-center operations generally, not unique to Costco Travel.

A Word on Scam Customer Service Numbers

Search results and social media for “[any travel company] customer service number” are a known target for scam listings — fake numbers that route to unrelated call centers, premium-rate lines, or third-party “concierge” services that charge a fee for what should be free support. Before calling any number for Costco Travel that you find on a random blog, forum, or sponsored ad, check that it matches what’s listed on costcotravel.com/Info/Contact-Us directly. If it doesn’t match, don’t call it.
