Stripe lost_card — recovery guide

lost_card means the customer has reported their card lost to their bank, and the bank has flagged the card as compromised. All further charges on that specific card number will be refused, regardless of merchant, amount, or circumstance.

The customer almost certainly already has a replacement card in hand (or will within a few business days). They just haven't thought to update it on your site yet.

Counter-intuitively, lost_card customers recover at much higher rates than card_declined or insufficient_funds customers. Reasons:

• They're not churning — they actively want to keep using your service.
• They already have a new card; just need to be reminded to update it.
• They're already in "updating cards everywhere" mode after losing their wallet.

Your email simply has to show up at the right moment with the right link.

1. +1h: email with Billing Portal link, friendly tone ("looks like you got a new card").
2. Disable auto-retry entirely — retrying a lost_card is pure waste.
3. +48h: second email if no update.
4. +5d: SMS — most effective channel for this code since the customer is phone-adjacent anyway.
5. +7d: final email + pause subscription.

Hi [name], looks like the card we had on file was reported lost. If you've already received a replacement, it takes 20 seconds to add it. We'll keep your account active in the meantime.

The "we'll keep your account active" reassurance matters — customers who lost a wallet are already stressed, and telling them they don't have to rush reduces churn.
