It means the three- or four-digit security code didn’t match what the bank has on record.
What happens next
The same decline, handled two ways: a fixed retry ladder, and Stripe Smart Retries with North Metric following up once they end. North Metric never retries a card; its part in failed payment recovery starts when Stripe stops.

The same wrong security code, four times. The details on file never change, so neither does the answer.

North Metric drafts a card-update note with its own link, at once if Stripe can’t retry the card, or when its retries end. You approve it first.
What it means
On a saved card this usually means the bank reissued it with a new code, not that the customer mistyped. Stripe returns it as a decline_code inside a card_error, so your integration sees the charge fail and the reason sits in this field.
•The security code didn’t match the one the bank has for the card.•The customer mistyped the three- or four-digit code when they saved the card.•The bank reissued the card with a new code, and the old details are still on file.
What to do
01Don’t add retriesThe same details will fail every time, so a new card is the fix.
02Send a hosted update linkOne click, card form prefilled, no login needed.
03Collect on the new cardOnce a new card is saved, the open invoice can be paid with it.

What to tell the customer
Be direct and short: the card on file needs updating, here’s the link, nothing else changes.
From: Maya at AcmeSubject: Your card on file needs a quick update
Hi Sam,
The card we have for Acme looks out of date, so this month’s payment didn’t go through.
You can update it here. Everything else stays the same.

SEND AT ONCE IF STRIPE CAN’T RETRY, OR WHEN ITS RETRIES END
What not to do
✕Retry the same card on a schedule.✕Ask the customer to log in before they can update.✕Pause the account before they’ve had a chance to fix it.
01RELATED CODES
Same type,same playbook.
Codes Stripe returns for the same underlying reason. Each one opens its own guide.
Short answers. The full list of codes is one click away.
Neither, exactly: a retry alone won’t work, but the customer can fix it (update card).
No, update first. The same details will fail every time, so a new card is the fix.
Stripe’s recommended default is 8 tries within 2 weeks, and it doesn’t retry hard declines such as lost_card or stolen_card until a new card is added (Stripe docs, Oct 2026). Card networks can penalize merchants for repeated retries.
Smart Retries pick when to retry, and North Metric doesn’t retry at all. When Stripe’s retries end unpaid, or Stripe can’t retry the code, North Metric drafts a personal note with a card-update link for you to approve.
