Adyen code 05 – Do Not Honor
This is a generic refusal with several possible causes. The shopper should contact their issuing bank for clarification.
What does Adyen refusal code 05 mean?
Adyen refusal code 05 Do Not Honor is the single most common generic decline in card processing. The issuing bank has refused the transaction but provided no specific reason. It maps directly to Stripe's do_not_honor and is one of the highest-volume declines any subscription business will see.
Is it a soft or hard decline?
Code 05 is a soft decline. The card itself is usually valid; the underlying cause varies — velocity, risk flags, temporary issuer conditions, or unrecognized merchant descriptors. Retries at the right time recover a meaningful share.
Common root causes
Issuer velocity or fraud-risk limits triggered
Geographic mismatch between cardholder and merchant
Unrecognized merchant descriptor on a recurring charge
Temporary issuer system conditions
Recommended recovery steps
Retry with intelligent, issuer-aware timing — not immediately.
Apply 3-D Secure where supported for lower risk scoring.
Clarify the merchant descriptor to reduce cardholder-initiated blocks.
If retries persistently fail, outreach for a backup payment method.
How FlyCode handles Adyen code 05
FlyCode's per-merchant ML models combine issuer-level retry data with Mastercard and Visa network-level signals to time retries optimally for each specific BIN. Because 05 is so common, small efficiency gains recover significant revenue. For persistent cases, FlyCode's AI outreach engine triggers at the optimal moment to request an alternate payment method.

Frequently Asked Questions
Is Adyen code 05 a soft or hard decline?
Is Adyen 05 the same as Stripe do_not_honor?
Yes. Adyen 05 and Stripe do_not_honor are the same underlying ISO response — both are generic refusals without a specific reason. The same recovery logic applies: smart retries plus outreach for persistent cases.
How does FlyCode recover Adyen 05 declines?
FlyCode's per-merchant ML models use Mastercard and Visa network-level signals to identify when a 05 decline will clear and schedule retries accordingly — recovering the majority of these automatically.
