Hello, @Paulkark! Thanks for dropping by. I'm happy to receive your first question in our Community forum. I'll help you locate your license number in QuickBooks Desktop.

Payment modes don't affect where you can locate your license number. However, there are different ways to find them based on how you purchase your QuickBooks Desktop. Here's how:

• If you bought a digital version of QuickBooks Desktop from our website, your product info is the original purchase confirmation email.
• Look for the label on the original package next to the UPC Code if you bought QuickBooks from a retail store.

Furthermore, you may always obtain your license number online as long as you registered your QuickBooks Desktop product. Check out this link: Customer Account Maintenance Portal.

You may want to read for more details about your product information. Please visit this article: Find QuickBooks Desktop license info.

I've included this article for your reference in managing your password for QuickBooks Desktop moving forward: Reset your password for QuickBooks Desktop.
