A UUID, or Universally Unique Identifier, is the unique identifier assigned to an e-Invoice after successful validation in the MyInvois framework. It helps identify the validated invoice in the system and supports retrieval, referencing, and related invoice processes.

Businesses should retain the UUID together with their invoice and transaction records. It should not be confused with the supplier’s own invoice number, which is a separate identifier.

Key points

  • UUID means Universally Unique Identifier.
  • It is assigned after successful validation.
  • It identifies the validated e-Invoice within the framework.
  • It is different from the supplier’s invoice number.
  • Store it with the relevant invoice and audit records.
