Stripe decline code: call_issuer

Call issuer — The issuer wants the cardholder to call them before authorizing further charges.

Common cause

Usually a soft fraud-flag or unusual-activity check.

Recovery strategy

Retry strategy	Retry after a delay
Customer-facing action	Ask customer to contact their issuer
Recovery rate (retry only)	~15%
Recovery rate (with customer flow)	~50%

What to do, in order

Wait 24h before retrying. Email the customer suggesting they call the number on the back of their card; many will, and the next retry succeeds.

Code example

The recommended Stripe Customer Portal session for the recovery flow:

session = stripe.billing_portal.Session.create(
    customer=customer_id,
    return_url="https://yourapp.com/billing/thanks",
    flow_data={"type": "payment_method_update"},
)
update_link = session.url

Where this fits in the bigger picture

call_issuer is one of dozens of decline codes Stripe returns; recovery rates vary by code by 5x or more. The recovery-rate reference covers the full set; the card-update flow article covers the customer-facing side; dunning emails covers how to write the messages.
