I'm not sure what you mean by "N0479". This doesn't appear to be a standard code or abbreviation. Could you please provide more context or clarify what you're asking about? Is it possibly related to:

1. A product or part number?

2. A medical code?

3. A reference in a specific system or database?

4. Something else entirely?

If you can give me more information, I'll do my best to help explain or find what you're looking for.
