The Unique Mandate Reference

By default the UMR is generated by the payment gateway.

However, the creditor can define its value according to the following requirements:

  • The UMR must be unique for each direct debit mandate.
    Any request for creating one-off or recurring direct debit mandate made with an existing UMR will lead to an error and a technical error message will appear.
  • The length must not exceed 35 characters.
  • The authorized characters are:
    • a b c d e f g h i j k l m n o p q r s t u v w x y z
    • A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
    • 0 1 2 3 4 5 6 7 8 9 / - ? : ( ) . , ' +
    • Space is not an authorized character.
