Where is the American visa number?

The visa number is a string of red numbers on the visa page below:

The red number in the lower right corner of the US visa page is your US Visa Number Visa Number. The visa number can be found on the visa label on the passport page. Numbers can be 8 or more characters long (letters +7 digits), displayed in red and located in the right quarter of the visa label in the lower right corner. Please note that the "control number" is not a visa number.

If you are a non-immigrant visa, such as B 1, B2, F 1, H 1B, then it is in the visa itself. The visa will be a beautiful sandwich sticker (at least new) on your passport, and the number will be a long number at the top of the visa. If you lose it, there will be some minor problems in getting the quantity, but you should contact the department or consulate of the country where you get the visa.
