    • isValidIBAN

      public static boolean isValidIBAN(String iban)
      Validates if the string is a valid IBAN number

      true if the IBAN is valid, false otherwise

    • isQRIBAN

      public static boolean isQRIBAN(String iban)
      Indicates if the string is a valid QR-IBAN.

      QR-IBANs are IBANs with an institution ID in the range 30000 to 31999 and a country code for Switzerland or Liechtenstein. Thus, they must have the format "CH..30...", "CH..31...", "LI..30..." or "LI..31...".

      Parameters:
      iban - account number to check
      Returns:
      true for valid QR-IBANs, false otherwise

    • formatIBAN

      public static String formatIBAN(String iban)
      Formats an IBAN or creditor reference by inserting spaces.

      Spaces are inserted to form groups of 4 letters/digits. If a group of less than 4 letters/digits is needed, it appears at the end.

      Parameters:
      iban - IBAN or creditor reference without spaces
      Returns:
      formatted IBAN or creditor reference

    • isValidISO11649Reference

      public static boolean isValidISO11649Reference(String reference)
      Validates if the string is a valid ISO 11649 reference number.

      The string is checked for valid characters, valid length and a valid check digit. White space is ignored.

      Parameters:
      reference - ISO 11649 creditor reference to validate
      Returns:
      true if the creditor reference is valid, false otherwise

    • createISO11649Reference

      public static String createISO11649Reference(String rawReference)
      Creates a ISO11649 creditor reference from a raw string by prefixing the string with "RF" and the modulo 97 checksum.

      Whitespace is removed from the reference

      Parameters:
      rawReference - The raw string
      Returns:
      ISO11649 creditor reference
      Throws:
      IllegalArgumentException - if rawReference contains invalid characters

    • isValidQRReference

      public static boolean isValidQRReference(String reference)
      Validates if the string is a valid QR reference.

      A valid QR reference is a valid ISR reference.

      The string is checked for valid characters, valid length and a valid check digit. White space is ignored.

      Parameters:
      reference - QR reference number to validate
      Returns:
      true if the reference number is valid, false otherwise

    • createQRReference

      public static String createQRReference(String rawReference)
      Creates a QR reference from a raw string by appending the checksum digit and prepending zeros to make it the correct length.

      Whitespace is removed from the reference

      Parameters:
      rawReference - The raw string (digits and whitespace only)
      Returns:
      QR reference
      Throws:
      IllegalArgumentException - if rawReference contains invalid characters

    • formatQRReferenceNumber

      public static String formatQRReferenceNumber(String refNo)
      Formats a QR reference number by inserting spaces.

      Spaces are inserted to create groups of 5 digits. If a group of less than 5 digits is needed, it appears at the start of the formatted reference number.

      refNo - reference number without white space
      Returns:
      formatted reference number
