Hello, @lightness-albatr. I'm here to help.
While the Business ID number is a 9-digit number, the Tax Identification Number (TIN) can vary depending on the country in which you reside or operate your business. To enter this information successfully in QuickBooks Online (QBO), I recommend checking with your tax agency first.
It is essential to understand the specific requirements and formats of TINs in the country where you are conducting business to ensure compliance with tax regulations and accurate reporting. In some cases, the TIN may be shown on official documents such as a certificate of tax registration, business license, identification card, or tax-paid certificates.
You can then refer to this article as a guide in updating your company information in QBO: Change company name, address, email address, and privacy settings.
