Mastercard 4853: cardholder dispute
4853 is Mastercard’s code for customer complaints about the purchase itself: not received, not as described, cancelled or never refunded. Most claims must be filed within 120 days. Your proof has to answer the exact complaint on the notice.
What 4853 means
Mastercard rolled most “I didn’t get what I paid for” complaints into one code: 4853, Cardholder Dispute. Under it sit several situations:
- Goods or services not as described, or defective.
- Goods or services not provided.
- A refund that was promised and never processed.
- A recurring charge after the customer cancelled.
- Extra charges added later, hotel no-shows and transactions that didn’t complete.
- A handful of rarer ones, such as counterfeit goods.
Older codes still show up on notices: 4841, 4855, 4859 and 4860. Mastercard’s Chargeback Guide says banks may still use them, but they will eventually be eliminated. Either way, the rules now come from 4853.
What the customer told their bank
Something like “It wasn’t what they promised,” “It never happened,” “I cancelled” or “They said they’d refund me.” The bank picks the 4853 condition that fits the story. Read your notice for which one it is. That condition is the question you have to answer.
Time limit
- Most 4853 claims: within 120 calendar days of the transaction.
- Not as described or defective: the bank waits 15 days after the return or cancellation, then has up to 120 days to file, counted from the transaction or the delivery date.
- Ongoing services that stopped: within 120 days of when they stopped, up to 540 days after the transaction.
Your side of the clock is shorter. Mastercard gives your bank 45 calendar days to send your response (Mastercard calls it the second presentment), and your processor keeps part of that. The due date on your notice is the one that counts.
What proof matters
Proof that answers the specific complaint: the description or agreement the customer saw, dated proof the goods arrived or the service happened, and the policy they accepted.
Not every complaint qualifies
Here’s one most merchants miss. 4853 is about whether the agreed goods or services were provided as agreed. Mastercard excludes claims such as negligence or damage to other property. Those belong somewhere else, not in a chargeback.
The common mistake
Answering the wrong complaint. A “we did the work” letter doesn’t answer “the work was defective.” The bank looks for a direct answer to the problem the customer raised.
