I 485 non immigrant visa number

[seal72]

I 485 request the non immigrant visa number. I have an old visa that I used to entered the US in 1999 that it was issued back in 1993, is like an ink colored stamp with a Number on the top (6 digits including two zeros 00XXXX). There is also like a smaller sticker in the middle with what it looks like the face of liberty lady with 6 numbers on the side (different than the first set of numbers) and a letter at the end. How can I tell which one is the visa number?

I included a photo but I have placed 2 black cover areas over the numbers.

Do you have H1 or H4 stamp on your passport? This one seems to be B1/b2 visa stamp which is non-immigrant intent visa whereas H1/H4 are dual intent visa.

no just this B1/B2 visa, I just don't know which number is the visa number? the top one which is 6 digits (00XXXX) or the 6 digits plus the letter on the sticker?
