Reference Generator

UUID · EndToEndId · InstructionId · MessageId · PayRef

Instantly generate payment references for testing and development. All values are generated locally in your browser using the Web Crypto API. Useful when building pain.001 initiation files or testing SEPA payment integrations.

EndToEndId

SEPA pain.001 end-to-end reference, max 35 chars (CdtTrfTxInf/PmtId/EndToEndId).

E2E-MN7BCZQP-XKZW8OBK
InstructionId

Payment instruction reference, max 35 chars (CdtTrfTxInf/PmtId/InstrId).

INSTRID-MN7BCZQP-R7Z3W5
MessageId

Reference formats

UUID v4128-bit random identifier (RFC 4122). Globally unique and safe for any system boundary.
EndToEndIdSEPA-compliant alphanumeric reference, max 35 characters (ISO 20022). Unique per transaction in a pain.001 file.
PayRefHuman-readable XXXX-XXXX-XXXX alphanumeric reference for display or logging use.

When to use this

Payment systems require unique identifiers at every level — the message (MsgId), the batch (PmtInfId), and each individual transaction (EndToEndId). During development, generating valid references saves time and avoids hard-coded test strings that accidentally appear in production logs or bank statements.
