An Agaserviceco Mar TT credit card charge can feel confusing if you don’t recall buying anything from a company with that name. In many cases, it is connected to travel protection sold by Allianz Partners, sometimes during a hotel or other travel booking.
AGA Service Company is the legal business behind Allianz Travel Insurance products in the United States. This guide explains the descriptor, its possible Marriott connection, cancellation rules, and what to do if you never authorized the charge.

What Is an Agaserviceco Mar TT Credit Card Charge?
An Agaserviceco Mar TT credit card charge typically points to AGA Service Company, which does business as Allianz Partners and Allianz Global Assistance in the United States.
AGA Service Company distributes and administers Allianz-branded travel protection plans. You may have purchased the coverage directly or during checkout with a hotel, airline, ticket seller, or another travel provider.
The charge is generally an insurance premium or travel protection payment. It is not typically a monthly subscription simply because the merchant name looks unfamiliar.
Your statement may abbreviate the business name because card descriptors have limited space.
What Does AGASERVICECO Mean?
AGASERVICECO is a shortened version of AGA Service Company.
Allianz’s own consumer information confirms that customers may see AGA Service Company on their credit card or PayPal statements after buying an Allianz insurance product.
The company is based in the Richmond, Virginia area. Its current US contact information lists 9950 Mayland Drive, Richmond, VA 23233.
You may also see statement descriptions such as:
- AGA SERVICE CO
- AGASERVICECO
- ALLIANZ TRAVEL INS
- ALLIANZ INSURANCE
- AGASERVICECO ALLIANZ
- AGASERVICECO MAR TT
- AGASERVICECO MAR T ALLIANZINS.US VA
The exact wording can vary by issuer and booking channel.
Does MAR TT Mean Marriott Travel Insurance?
There is strong evidence that this particular descriptor may appear with Marriott travel protection purchases.
Marriott currently offers Allianz Travel Protection to eligible customers. Marriott’s official travel insurance site identifies AGA Service Company as the licensed producer and administrator of the Allianz plans it sells.
However, neither Marriott nor Allianz appears to publish an official definition of the letters MAR TT in the card descriptor.
It is therefore reasonable to treat a Marriott booking as an important clue, but you should not assume the letters themselves officially stand for a specific phrase.
Pro Tip: If you recently booked a Marriott hotel, search your confirmation email for “Allianz,” “travel protection,” “trip insurance,” or “AGA Service Company.” The insurance payment may be separate from the hotel charge.
Why Did You Get the Charge?
You may have purchased travel insurance while completing another transaction. This can make the charge easy to forget because you remember the hotel, flight, or event instead of Allianz.
Possible situations include:
- A Marriott hotel reservation
- Another hotel booking
- An airline ticket
- A vacation package
- An event ticket
- Trip cancellation coverage
- Travel medical coverage
- Rental car protection
- Registration protection for an event
Allianz partners with travel and entertainment companies that offer protection during checkout.
The insurance charge can post separately from the main booking. That separation is one reason cardholders may not recognize it.
Is Agaserviceco Mar TT a Recurring Subscription?
Usually, you should not assume it is a subscription.
Many Allianz travel insurance policies protect one specific trip. You pay the policy price when you purchase the protection.
Allianz also sells annual travel insurance products. Those plans have different terms and may cover multiple trips.
Check your policy confirmation to determine exactly what you purchased. It should identify the plan, insured trip, coverage period, and price.
How to Verify the Charge
Start with purchases made near the transaction date.
Look for recent Marriott reservations or other travel bookings. Then search your email for Allianz or AGA Service Company.
Check:
- Marriott booking confirmations
- Airline reservations
- Hotel receipts
- Event tickets
- Vacation package purchases
- PayPal activity
- Travel insurance emails
- Policy confirmation documents
- Purchases made by another authorized card user
The amount on your card should generally match the plan price shown in the confirmation.
If you purchased Marriott travel protection, the official Marriott Allianz portal also provides a way to manage an existing plan.
What Does Allianz Travel Protection Cover?
Coverage depends on the exact plan you bought.
Marriott’s current Allianz travel protection offering may include benefits for certain covered trip cancellations, interruptions, delays, baggage problems, and emergency medical situations.
Some plans may also include assistance services.
Insurance benefits have conditions, exclusions, and coverage limits. Buying travel protection does not mean every canceled hotel stay, missed event, medical expense, or trip problem is automatically reimbursed.
Read the policy documents before filing a claim.
Common Mistakes: Do not assume the insurance guarantees a refund whenever your travel plans change. A claim generally has to meet the covered reasons and other requirements in your specific policy.
Can You Cancel an Agaserviceco Mar TT Charge?
If the payment represents a newly purchased Allianz travel protection plan, you may be able to cancel the policy.
Marriott’s current Allianz travel protection page provides a 15-day free-look period. It says you can generally cancel within 15 days and receive a full refund of the plan price if you are not satisfied.
Restrictions apply. The plan is generally no longer refundable after that period or once your trip has started, a claim has been filed, or the policy has ended.
Cancellation rules can also vary by plan and state.
Check the confirmation documents for the terms applying to your purchase.
How to Contact Allianz About the Charge
The Marriott Allianz travel protection page currently lists 800-284-8300 for AGA Service Company.
It also lists customerservice@allianzassistance.com and the following address:
AGA Service Company
9950 Mayland Drive
Richmond, VA 23233
Use the contact details in your own policy confirmation when available. Those details are generally the safest option because different Allianz products may have different support channels.
When contacting Allianz, have the transaction date, charge amount, booking information, and policy number ready.
Do not send your complete credit card number through ordinary email.
Can You Get a Refund?
A full refund may generally be available during the applicable free-look period if you meet the policy requirements.
For Marriott Allianz plans, the current published period is generally 15 days.
After that period, the insurance premium is usually non-refundable unless your specific plan or state law provides otherwise.
A refund of your insurance premium is different from an insurance claim. Canceling the policy requests your premium back, while filing a claim asks Allianz to reimburse a covered travel loss.
Is AGA Service Company Legitimate?
Yes. AGA Service Company is an established US insurance producer and administrator associated with Allianz Partners.
Allianz confirms the connection on its official website. Marriott also identifies AGA Service Company in its travel protection disclosures.
Trustpilot currently shows Allianz Partners USA with a rating of about 4.1 out of 5 based on roughly 200,000 reviews. Many reviewers report positive claim experiences, while others report denied claims, delays, or disagreements over policy coverage.
BBB information specifically tied to the abbreviated AGASERVICECO MAR TT descriptor is limited. That means consumer complaint sites should not be used to determine whether your individual transaction was authorized.
What If You Don’t Remember Buying Travel Insurance?
Check the booking process that happened around the same date.
You may have selected travel protection during checkout and focused mainly on the hotel or trip price. The insurance confirmation may have arrived in a separate email.
Search for:
- “Allianz”
- “AGA Service Company”
- “Travel Protection”
- “Trip Protection”
- Your hotel name
- Your reservation number
Also ask another authorized card user whether they booked travel.
If you identify an Allianz policy but do not want it, check whether you are still within the cancellation window.
What If You Never Authorized the Charge?
Take a different approach if you have no travel booking, no Allianz confirmation, and nobody authorized to use your card recognizes the payment.
Contact your credit card issuer promptly. Ask for the complete merchant descriptor and explain that you do not recognize the transaction.
Your issuer may:
- Investigate the payment
- Open a billing dispute
- Block additional transactions
- Replace your card
- Ask for supporting information
You should also review nearby transactions for other unfamiliar charges.
Do not contact a phone number taken only from an unknown text message or email. Use your card issuer’s official number or verified Allianz contact details.
