What is anbc in banking?

That's not a standard banking term, mate. I reckon it’s most likely a typo. You might be thinking of ANZ, which is the Australia and New Zealand Banking Group, one of our major banks. It could also be ABN, the Australian Business Number, which is vital for business accounts. Double-checking where you saw the term should clear things up for you. It's an easy mistake to make with all these acronyms flying around.
