What this variant means
A combined descriptor where the marketplace line carries the billing entity. Your order details live at amazon.com/your-orders.
AMZN MKTP is an Amazon Marketplace order — a purchase from a third-party seller sold through Amazon. It's the single most-searched mystery charge, and it's almost always a real order.
Why it shows up like this
Amazon splits its billing names: MKTP covers third-party marketplace sellers (most of what's on Amazon), while first-party items, digital content, and subscriptions bill under other Amazon descriptors. The random code after the asterisk is an internal reference, and one multi-item order can split into several charges as sellers ship separately.
Don’t recognize it? You might still
- One order, many charges — Amazon bills per shipment, not per checkout.
- The charge posts when the item ships, which can be days after you ordered.
- Household members on the same account or card generate identical-looking entries.
- Subscribe & Save items recur on their own schedule.
What to do, in order
- Open your Amazon orders Go to Your Orders and match by amount. Remember one checkout can produce several partial charges that sum to the order total.
- Check other profiles on the account Household profiles and shared payment methods are the top source of 'unknown' Amazon charges.
- Use Amazon's unknown-charge tool Amazon has a dedicated flow for unrecognized charges that can match a charge to an order or flag it as fraud.
Quick questions
The amount doesn't match any order. Is it fraud?
First add up per-shipment charges within one order, and check digital purchases and Subscribe & Save. If nothing sums to the amount, report it through Amazon's unrecognized-charge flow and your bank.
