What is the standing order reference, and why do I need it?
A standing order reference is a mandatory code unique to your account, provided by the billing company.
Its purpose is to distinguish your payments from anyone else's, in order to process them correctly. It is generally your account number or customer number, as provided by the company you are paying.
If your payment is to an individual (eg. Friends or family), your reference is simply so that the recipient can identify where the payment came from Failure to provide a valid reference may result in your payment being returned, so make sure you enter it correctly.
