How to request your merchant/terminal ID from your bank to allow internet payments

So you have signed up to onCourse and you are excited about getting online enrolments up and running. To allow us to enable this feature, you will need to contact your bank and have them provide you with some details of your merchant account. If you don’t already have a merchant account, then you will need to establish that first. All banks will be happy to help you do this and in fact will be quite competitive over your business: don’t hestitate to haggle over the best merchant rate.

We support the following banks:

  • ANZ Australia
  • Bank of South Australia
  • BOQ
  • Bank West
  • CitiGroup
  • Commonwealth Bank
  • National Australia Bank
  • St George
  • Westpac Australia

Once we have received your details we will be able to set you up as an Internet Merchant in our system and you will be able to process credit cards directly into your bank account. If you have any further questions regarding this, you may also phone ish on 02 9550 5001 or email

You will need to supply ish with the following details:

Merchant ID

This is an electronic merchant number generated by the bank specifically for your business to be able to transact online. ANZ Australia may also refer to this field as an ‘EPOS Number’.

Terminal ID

This is a number associated with the ‘Merchant ID’. A merchant can have one or many Terminal IDs. Commonwealth Bank customers will not have a Terminal ID at all. All other banks will issue one.

Card acceptor name

This is the name that appears on the card holders’ statement. This field must have no more than 25 characters.

Card acceptor location

This is the physical location of business operation. This is usually the town or city of your business.

Merchant category code

Your bank will assign you with a merchant category code based on your business type.

If you wish to accept American Express cards (AMEX):

(AMEX Terminal ID and Merchant ID)

If you are an existing American Express merchant call American Express directly on 1300 363 614 option 3 and ensure your current merchant number is exclusively in use with DPS. If not please request an additional merchant number exclusively for DPS use. Please also request that American Express issue a terminal ID for the Merchant number to be used in DPS processing.

If you are not currently an American Express merchant call American Express directly on 1300 363 614 option 4 and discuss becoming an American Express merchant, requesting a “merchant number” and “terminal ID” for DPS use.
