What does card decline code 5C mean?

Checked October 31, 2026

Code 5C is a Visa issuer response code meaning "transaction not supported/blocked by issuer". The card's bank either does not support this kind of transaction or has blocked it. Visa lists 5C in Category 2, "issuer cannot approve at this time", which permits up to 20 reattempts in 30 days. The shopper can ask the bank to allow the payment, or pay with another card or PayPal.

Type: Soft decline (issuer block)
Who declined: The card's issuing bank
Visa category: Category 2 (issuer cannot approve at this time): up to 20 reattempts in 30 days
Retry: After the cardholder asks the bank to allow it
Shopper action: Contact the bank or use another card
Merchant action: Offer another payment method
PlatformDTC renewal (Smart retry): No rule for this raw code; the processor's own code decides

What PlatformDTC does

PlatformDTC has no rule for a raw 5C, so Stripe's own decline code decides the renewal path: with Smart retry on, a refer-to-issuer code gets one retry after 48 to 72 hours, and on either retry schedule a hard code stops and asks for a new card. Every attempt counts toward the per-card Visa cap of 20 declines in 30 days, which PlatformDTC enforces before charging.

Why it happens

The issuer blocks or does not support this transaction type, for example online, foreign or certain merchant categories, on this card.

What the shopper can do

Check the card's settings in the banking app or call the bank, then try again. Another card works straight away.

For developers

On Stripe the raw issuer code arrives in charge.outcome.network_decline_code (here "5C"), next to Stripe's own decline_code. Read it together with the card brand: the same two characters can mean different things on Visa and Mastercard. 5C is in Stripe's Visa table and Visa's Category 2 list. It is not in PlatformDTC's networkDeclineCodeMap.
