AGASERVICECO MAR TT Charge on Credit Card [Identified]
An AGASERVICECO MAR TT charge on credit card can look like a code, not a brand you know. You may see a long string and a Virginia tag. That mix often feels off after a hotel booking.
In most cases, this line is travel protection billed by AGA Service Company. Check your Marriott confirmation and email before you assume fraud.
What Is an AGASERVICECO MAR TT Charge on Credit Card?
An AGASERVICECO MAR TT charge on credit card typically comes from AGA Service Company. That company is the U.S. licensed producer and administrator behind Allianz Travel Insurance. State records list it at 9950 Mayland Drive, Richmond, VA 23233.
AGA Service Company also does business as Allianz Partners and Allianz Global Assistance. Policy papers often say Allianz Global Assistance branded plans are administered by AGA Service Company.
MAR TT is not printed in Allianz’s public glossary. Consumer statements and Marriott help pages most often tie this exact string to trip protection offered during a Marriott reservation.
MAR generally appears to flag the Marriott booking path. TT generally appears to flag travel protection. Treat that reading as an educated match, then confirm it with your policy number.
The charge is usually a one-time premium, not a stay at the hotel. Marriott bills the room separately. Insurance posts under AGA because Allianz processes that product.
This is not a gas-stove repair shop and not a local HVAC firm. Those businesses can share “AGA” in their names. The MAR TT plus VA or ALLIANZINS wording points to Allianz travel coverage.
How this charge may appear on your statement
Banks shorten names in different ways. The same premium can look different from one issuer to the next.
You may see lines such as:
| Statement text you may see | What it typically points to |
|---|---|
| AGASERVICECO MAR TT | AGA travel protection, often from a Marriott checkout |
| AGASERVICECO MAR T ALLIANZINS.US VA | Same company, with the Allianz and Virginia tags |
| AGA SERVICE CO MAR TT | Spaced version of the same descriptor |
| AGASERVICECO MAR TT 8042853300 VA | AGA billing plus a Virginia phone tag |
| CHECKCARD or POS AGASERVICECO MAR TT | Bank prefix on the same insurance charge |
You may also see PRE-AUTH or PENDING first. Those tags usually mean the bank is holding the amount until it settles.
The hotel stay itself should still show as Marriott, Bonvoy, or the property name. Compare both lines. Different dates are common because insurance can post a day or two later.
Common reasons you may see this charge
The most common source is optional trip protection added while booking on Marriott.com or in the Bonvoy app. Marriott’s help pages say Allianz plans are offered on the payment page for eligible reservations.
A coworker or family member may have booked rooms on your card and checked the protection box. One community report described several small AGA lines after multiple Marriott reservations.
Event or ticket protection can also bill through AGA Service Company. That is less tied to the MAR letters, but the AGA name can still print.
A refund or adjustment can reuse the same descriptor. If you canceled the plan, a credit may take several days.
This product is generally not an annual club you forgot. Many trip plans cover one stay. Still search for any older Allianz policy email if the amount repeats.
How to verify the charge
Open the Marriott confirmation for that date. Look for travel protection, Allianz, or a plan price that matches the card line.
Search your email for “Allianz,” “AGA Service,” “travel protection,” or “trip insurance.” Check spam. The policy packet should list a plan number and the travelers covered.
Log in at allianztravelinsurance.com if you created an account. You can also use the Allyz app that Allianz promotes for plan and claim help.
If the booking was for work, ask the traveler whose name is on the reservation. The insurance email may have gone to them, not to the cardholder.
Have the charge date, amount, and last four card digits ready before you call. Do not use a number from a surprise text. Open allianztravelinsurance.com or help.marriott.com yourself.
How to cancel and request a refund
Marriott’s help pages say guests typically have a 15-day free-look period to cancel the Allianz plan for a full refund. That window generally applies if the trip has not started and no claim has been filed. Your own plan documents control the exact rule. State law can change the timeline.
Call Allianz about the policy, not only the hotel. Official Allianz Travel Insurance pages list customer service at 1-866-884-3556. Policy documents also list 1-800-284-8300. Marriott’s travel-insurance article lists Allianz Global Assistance at 1-888-897-2661 for purchase and plan questions after booking.
Ask for the plan number, cancel effective date, and refund method in writing. Keep that email with your statement.
Canceling the hotel reservation does not always cancel the insurance automatically. Ask Allianz if the premium should reverse when the stay is canceled.
Refund timing varies. Watch the same card for a credit that may reuse the AGASERVICECO name.
What to do if you do not recognize the charge
Stay calm and finish the Marriott and email checks first. Many surprise AGA lines are a protection box checked at checkout.
If no booking or policy matches, call Allianz with the statement details. Ask which email and reservation sit on the sale.
Then call the number on the back of your card. Tell your issuer you have an unrecognized AGASERVICECO MAR TT charge. Ask about a dispute. Issuer rules and deadlines vary.
Watch for lookalike texts. A message that says “Allianz” or “Marriott insurance” and then asks you to pay a new link is a common scam pattern. Hang up. Use official sites only.
If the card was copied, ask your issuer to replace it. Review other recent travel charges the same day.
Similar names and lookalikes
ALLIANZINS.US VA is the same Allianz U.S. billing family, not a second unknown insurer.
804-285-3300 on the statement is a Virginia phone tag often printed with AGA lines. Confirm any number on allianztravelinsurance.com before you call it.
Aga range cookers and local “AGA Service” repair shops are different businesses. They do not typically print MAR TT and ALLIANZINS.US VA.
Allstate home or auto billing uses other names. Do not mix that company with AGA Service Company.
FAQs About AGASERVICECO MAR TT Charge on Credit Card
Q: Is an AGASERVICECO MAR TT charge on credit card always Allianz?
Usually, yes, when the line also shows VA or Allianz wording. AGA Service Company is the registered U.S. administrator for Allianz Travel Insurance. Confirm the plan number before you treat it as settled.
Q: Did I visit a store in Virginia?
Not typically. Richmond, Virginia, is AGA Service Company’s office city. Card networks often print that state even when you booked a hotel in another city.
Q: Why is this separate from my Marriott room charge?
The hotel bills the stay. Allianz bills the optional protection. They are two merchants. That is why the insurance line can post later and use a different name.
Q: How do I stop another AGASERVICECO MAR TT charge?
This is usually a one-trip premium, not a monthly club. Uncheck travel protection on future Marriott checkouts. If a plan is already active, cancel it with Allianz using the contacts on your policy or allianztravelinsurance.com.
Conclusion
An AGASERVICECO MAR TT charge on credit card typically is Allianz travel protection administered by AGA Service Company, often added during a Marriott booking. It is not the hotel folio itself.
Match the amount to your reservation and policy email. Cancel inside the free-look window if you do not want the plan. If no policy exists, contact Allianz and your card issuer the same day.
