Adding more than 12 digits for a customer's BRN is a thoughtful idea, @ZS Chong. However, the option to do so is currently unavailable.
In QuickBooks Online (QBO), please note that we're only allowed to input a unique set of 12 digits in Business Registration Numbers (BRN) for customers. The 12-digit BRN also serves as a standardized and unique identifier for businesses, ensuring compliance with local regulatory requirements.
Through this, it ensures accurate data entry and consistency in generating localized reports, invoices, and filings that align with business standards.
