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.
Legacy Visa dispute-code mapping
Still seeing retired Visa dispute codes 83, 76, 71, or 75 in an old chargeback file or archived acquirer export? See what they map to today — and how to tell them apart from unrelated decline codes.
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.
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.
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.
PSP Selection RFP Template
60+ structured questions, an evaluation scorecard, a 5-lever negotiation playbook, and a 10-point red flag checklist for choosing a payment service provider.
