AGASERVICECO MAR TT is a legitimate billing descriptor for AGA Service Company, the legal entity behind Allianz Global Assistance (also called Allianz Travel Insurance). It usually appears after you buy trip protection during a Marriott booking “MAR” points to Marriott, and “TT” stands for travel protection. In most cases it’s not fraud, but you can still cancel and get a full refund within a short window if you act fast.
What Is the AGASERVICECO MAR TT Charge?
You’re scanning your statement, and there it is: AGASERVICECO MAR TT. No company name you recognize. No obvious link to anything you bought.
Here’s the good news this charge has a clear, well-documented explanation. It’s travel insurance, almost always tied to a hotel or trip booking, and it’s billed by a company most people have never heard of, even though the insurance brand behind it is one of the biggest in the world.
That mismatch between familiar brand, unfamiliar billing names is exactly why this charge causes so much confusion.
Who’s Really Behind This Charge?
Card statements don’t bill under marketing names. They bill under legal entity names, which is why “Allianz” never shows up, even though Allianz is who actually insured your trip.
| Detail | What It Actually Is |
| Billing entity (legal name) | AGA Service Company |
| Consumer brand | Allianz Global Assistance / Allianz Travel Insurance |
| Parent company | Allianz Partners |
| Common booking channel | Marriott International (“MAR”) |
| Typical billing address | AGA Service Company, Richmond, VA (associated with the 9950 Mayland Drive corporate address) |
| Associated phone number | 804-285-3300 |
| Product type | Optional trip protection / travel insurance |
If you booked a hotel, flight, or vacation package and were offered “trip protection” at checkout even briefly, even as a checkbox you don’t remember clicking, that’s very likely where this charge came from.
What Does “MAR TT” Actually Mean?
MAR TT is shorthand baked into the payment processor’s descriptor field, which has strict character limits. Based on the pattern across statements:
- MAR refers to Marriott, the booking channel where the insurance was offered
- TT refers to travel protection / travel insurance
Put together, “MAR TT” is essentially the processor’s compressed way of saying “Marriott travel protection.”
All the Ways This Charge Appears on Statements
Different banks and processors format the same underlying charge differently. If you’re trying to match this against your account, look for any of these variants they all point to the same AGA Service Company / Allianz charge:
- AGASERVICECO MAR TT
- AGASERVICECO MAR T ALLIANZINS.US VA
- AGASERVICECO MARRIOTT
- AGA SERVICE CO RICHMOND VA
- CHKCARD AGASERVICECO MAR TT
- CHECKCARD AGASERVICECO MAR TT
- POS DEBIT / POS PUR / POS PURCHASE AGASERVICECO MAR TT
- POS REFUND AGASERVICECO MAR TT
- PRE-AUTH AGASERVICECO MAR TT
- PENDING AGASERVICECO MAR TT
- VISA CHECK CARD AGASERVICECO MAR TT VA MC
- MISC. DEBIT AGASERVICECO MAR TT
If your statement shows a pending version of this charge, don’t panic pending authorizations are temporary holds and sometimes drop off without ever posting as a real charge. Give it a few business days before assuming it’s final.
Clearing Up the Confusion: This Isn’t Apple or an HVAC Charge
A few pages floating around the internet connect this descriptor to Apple digital purchases, or to gas-appliance and HVAC servicing. Neither lines up with the evidence.
The Apple mix-up appears to come from confusing an unrelated billing pattern with this one. The HVAC/appliance angle likely comes from a naming coincidence: “AGA” is also the name of a well-known cooker and appliance brand, unrelated to AGA Service Company, the insurance billing entity.
Across community-reported statement data, verified merchant identifiers, and Allianz’s own corporate structure, the consistent, well-supported identification is: AGA Service Company = Allianz travel insurance billing name, tied almost always to a Marriott or travel booking. If you see this charge and don’t have a recent Apple purchase or HVAC service call to point to, don’t let those unrelated theories send you down the wrong path.
How Much Does It Usually Cost?
Travel protection pricing scales with trip cost and coverage level. Based on typical Allianz-affiliated policy tiers:
- $15–$40 Basic trip cancellation coverage for a single flight or short stay
- $50–$120 Comprehensive protection for a full vacation package (flight + hotel)
- $150–$300+ Annual multi-trip plans or higher-coverage policies
If the amount on your statement roughly matches your most recent travel booking, that’s a strong signal the charge is tied to that trip.
Is AGASERVICECO MAR TT a Scam?
In the overwhelming majority of cases, AGASERVICECO MAR TT is a legitimate charge from AGA Service Company for travel insurance purchased (often unintentionally) during a Marriott or travel booking. It’s not a common fraud pattern. That said, “usually legitimate” doesn’t mean “automatically yours to keep” if you don’t recognize any recent travel purchase at all, it’s still worth verifying before assuming it’s fine.
How to Verify the Charge Is Legitimate
- Check your email for a policy confirmation Allianz typically sends one at the time of purchase, often buried in a promotions or updates folder.
- Match the date and amount on your statement to a recent hotel, flight, or event booking.
- Look up your policy directly through Allianz Partners’ policy management tool, using your email address or policy number.
- Call 804-285-3300 if you want to speak with the billing entity directly and confirm the charge.
If the timing and amount line up with something you booked, you’re almost certainly looking at a real, if unwanted, travel insurance purchase.
How Do I Cancel and Get a Refund?
Most travel insurance sold this way includes a “free-look” cancellation window typically 15 days from purchase (this can run longer depending on your state).
Here’s how to use it:
- Act inside the window. If you’re still within roughly 15 days of the purchase date, you’re eligible for a full refund as long as you haven’t started your trip or filed a claim.
- Cancel through the policy portal. Log in to Allianz’s policy management tool using your policy number or the email tied to the booking.
- Call if you can’t find the policy online. Use 804-285-3300 or the customer service line listed on your confirmation email.
- Ask for written confirmation of the cancellation and refund once it’s processed.
If the free-look window has already passed, you can still contact Allianz customer support refunds outside the window aren’t guaranteed, but accidental opt-ins and unwanted renewals are common enough that it’s worth asking.
Your Legal Right to Dispute
If you genuinely don’t recognize the charge and can’t tie it to any booking at all, you have a formal path forward. Under the Fair Credit Billing Act, cardholders generally have 60 days from the date a charge appears on their statement to send their card issuer a written billing-error notice. That notice should include your name, account number, the disputed amount, and the reason you believe it’s an error.
This is a separate process from Allianz’s free-look cancellation; use the FCBA dispute route specifically when you believe the charge wasn’t authorized at all, not just when you regret an add-on you did select.
Why This Charge Blindsides So Many Travelers
Here’s the pattern worth understanding, not just the fact: travel protection add-ons are frequently presented at the exact moment a traveler is focused on finishing checkout, not evaluating insurance. On many booking flows, the protection option defaults to selected, and opting out requires actively unchecking a box rather than actively checking one.
That single design choice default-on instead of default-off is very likely the single biggest driver of “surprise” AGA Service Company charges. It’s not deception in the fraud sense; it’s a checkout pattern that quietly shifts the burden of noticing onto the traveler. Knowing that pattern exists is often more useful than any refund process, because it’s the thing that lets you catch the charge before it happens on your next booking.
Conclusion
AGASERVICECO MAR TT is AGA Service Company’s billing name for Allianz travel insurance, most often tied to a Marriott booking where trip protection was added sometimes without a clear, active choice. Match the amount and date to a recent trip to confirm it, use the 15-day free-look window to cancel for a full refund if it was unwanted, and fall back on your Fair Credit Billing Act dispute rights only if you can’t tie the charge to any booking at all.
FAQs
Is AGASERVICECO MAR TT the same as Allianz Travel Insurance?
Yes. AGA Service Company is the legal billing entity, while Allianz Global Assistance / Allianz Travel Insurance is the consumer-facing brand name for the same product.
Why does my Marriott charge Allianz on it?
It doesn’t, that’s the confusing part. The charge shows AGA Service Company’s billing name, not Allianz’s, because merchants bill under their registered legal entity name rather than their marketing brand.
Can I get a full refund on this charge?
Usually, yes, if you cancel within the 15-day free-look window and haven’t started your trip or filed a claim. After that window, refunds are possible but not guaranteed.
What if I never bought travel insurance?
Check for a recent travel booking first. This add-on is easy to select accidentally. If you find no matching booking at all, treat it as a potential unauthorized charge and use your FCBA dispute rights with your card issuer.
Is this charge a sign of fraud?
Rarely. It’s overwhelmingly associated with legitimate travel insurance. Fraud is possible with any charge, so if nothing about your recent activity matches, verifying with your issuer is still the right move.
