Subsidiary Designations

A subsidiary designation identifies how your service is set up. Subsidiary designations can be assigned as Operating or Non-Operating. A client without a subsidiary designation is identified as “Centralized“. Subsidiary Designations are recommended to larger corporations or companies that have multiple offices involved in the processing/reconciliation of their ACH Payments.

RBC Royal Bank will assign a Client Account Number to you that contains the following:

  • A six digit Basic number
  • Followed by a four zeros, for “Centralized” designation

    Followed by a four digit Subsidiary number assigned to identify your company’s unit or service for “Operating or “Non-Operating” designations. These numbers will be zeros where the parent number has been opened first.

Client Number Format

The six digit Basic portion of the Client Account Number is common to all payment services provided to your company by RBC Royal Bank. Initially we will assign “0000” to the 4 digit Subsidiary portion of your Client Account Number. You can only change the last 4 digits of your Client Account Number if you are set up with a designation of “Operating“ or “Non-Operating“ and this must be done at the time of set up. The last 4 digits can be assigned other numbers to identify:

  • Branches or departments
  • Types of services

Centralized Designations

Clients choosing not to have any subsidiary designations are termed “Centralized.” This term means that you will have one account that:

  • Produces transaction files with the same Client Account Number throughout (i.e. on the header, detail records, and trailer records).
  • Has one control account.
  • Has one return account, which may be different from the control account.

The Client Account Number assigned by RBC Royal Bank to a Centralized account will contain:

  • A six digit basic number, followed by four zeros.

An Operating Subsidiary

Under this designation, each subsidiary can have a customized level of control.


  • Separate transaction files can be produced for each subsidiary, but may be sent with the same transmission.
    • Each subsidiary must submit their file with their Client Account Number consistently throughout the file.
    • A separate header, detail and trailer record must be provided.
  • Each subsidiary may have a different control account from the parent client.
  • Each subsidiary may have a separate return account designated for their returned items.
  • An output report/data file is produced separately for each subsidiary, or a file may be produced covering all subsidiaries.

Operating subsidiary reports are provided to the subsidiary. If you wish to receive all the subsidiary reports please advise your Cash Management Client Support Centre at the time of set-up.

Non-Operating Subsidiary

Under this designation, one control account oversees all subsidiaries’ accounts and their activities.


  • One transaction file is produced by the client and covers all subsidiaries.
  • The Client Account Number for the Header and Trailer records will be that of the Parent Client Account Number (XXXXXX0000),
  • The Detail records will contain the various Subsidiary Account Numbers (XXXXXX0001, XXXXXX0002, etc.).
  • Only one control account can be designated.
  • A separate account may be designated for each subsidiary’s returned items.
  • Reports are produced for the parent company and only the following reports identify the “totals” for each subsidiary:
    • File Input Payment Confirmation Report
