Please help: What is nonimmigrant visa number in I-485 form?

What is nonimmigrant visa number in I-485 form? I changed my visa from F1 to H1B in US. I only have F1 visa stamp on my passport. I could not find any number on my H1B approval notice except I-94 number.

Thank you very much for your help!
