invalid_number: Invalid card number

What invalid_number means

invalid_number means the number failed validation. Stripe treats it the same as incorrect_number.

Should you retry the payment?

Ask the customer to re-enter or replace the card.

How to recover a subscription payment declined with invalid_number

1. Email the customer a link to re-enter their card details on your billing page.
2. Do not retry the stored card: the same data will be declined again.
3. Once the details are corrected, collect the open invoice immediately.

What to tell the customer

Ask them to re-enter the card number or use another card.

"Hi Sam, the card number on your account isn't valid. Please update your card here."

More wording for every situation is in our dunning email templates.

How Revnio handles invalid_number

Revnio records invalid_number on the failed payment, follows your retry schedule (by default 1, 3, 5 and 7 days, adjusted for the customer's value and plan, and moved to weekday business hours), and emails the customer a secure link to pay or update their card. WhatsApp (Pro plan) reminders follow if the email is not clicked. The Insights page shows how often each decline code recovers for you. On Paddle, Paddle runs the payment retries itself and Revnio handles the customer outreach.

Decline codes are returned by the card issuer through your payment processor. Code names here follow Stripe's; Chargebee and Paddle surface the same issuer reasons with their own wording. Last reviewed 2026-10-15.
