An Amazon barcode is a code used to identify a product. It can be scanned with a barcode scanner.

Here are some possible methods:

1. Use a barcode scanner: You can use a special barcode scanner and aim it at the Amazon barcode to scan it. The scanner will automatically recognize and read the information in the barcode.

2. Scan with a smartphone: Many smartphones have built-in barcode scanning functions. You can use the phone camera to scan the Amazon barcode and then use the corresponding application to read the information in the barcode.

3. Look up on the Amazon website: If you know the ASIN (Amazon Standard Identification Number) or product name of the product, you can search and find the corresponding product page on the Amazon website, and then check the barcode information in the product details.

It should be noted that some Amazon barcodes may be unique and can only be used to identify specific products, while some barcodes may be universal and can be used to identify multiple products. Therefore, when scanning an Amazon barcode, you need to make sure that the scanner or application you are using can correctly identify and read the information in the barcode.
