Interactive lookups
Start with a code or message type and check its meaning, scope and next step.
Chargeback Reason-Code Lookup
Look up any of the 22 active Visa Claims Resolution and Mastercard Mastercom reason codes — trigger, defense evidence, and response deadline in one card.
Example input: a dispute reason code → see the evidence to investigate.
SEPA Return & Reject Code Lookup
Look up any SEPA R-transaction reason code across SCT, SCT Inst, SDD Core, and SDD B2B — meaning, rulebook scope, who generates it, and what to do next.
ACH Return Reason Code Lookup
Look up any Nacha return code, R01 to R85 — Nacha's own definition, SEC scope, the camt.053 mapping, and the time frame and reinitiation position where Nacha publishes them. Where it does not, the card says so.
Example input: R10 → see the return meaning and applicable time frame.
MT to ISO 20022 Message Equivalence Lookup
Bidirectional lookup for SWIFT MT to ISO 20022 equivalence — pacs, camt, and pain messages, each with an honest equivalence tier. CBPR+ migration is not message-for-message.
Example input: MT103 → see candidate ISO messages and the equivalence caveat.
Card Decline-Code Lookup
Look up any of 16 cross-source-corroborated card decline codes — meaning, variability, retryability, and operator action. Not current ISO 8583.
References and templates
Use a focused reference or a structured procurement worksheet.
