Added a new employee. Unable to edit and save his SIN number. When trying to save I get the an error message. " Doesn't look like the right SIN number. Try again"

Hi there, 

Thanks for joining us in the Community. It's essential you're able to add a new employee with ease in QuickBooks. Rest assured, I'll be happy to point you in the right direction so you can get back to doing what you enjoy. 

The issue you've described above sounds like a browser-related issue, especially after double-checking to make sure the SIN number is entered correctly before saving. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead. Try this out and let me know what happens. In case this issue persists, I encourage you to contact our support team so they can assist you further with this. Here are our contact details:
