That is almost like asking how many digits are in a number. The only limit is the amount of space available for a barcode. Even the size of most scanners does not create an absolute limit because there are barcode readers that look like a pen and read the barcode information serially (one digit at a time).
Perhaps you would like to rephrase your question to find out about a particular barcode application. For example, Universal Product Codes (UPC's) usually have ten digits. The first five identify the manufacturer or distributor, and the other five identify a unique product, including a particular size or quantity of the product. UPC's do not contain any price information; that information is cross referenced by the store's computer after the UPC is scanned.

10 bits would be required. 10 bits long (10 digits long) can represent up to 1024.

An International Article Number, also called an ean-13, has 13 digits. The original Universal Product Code has 12 digits. The barcode became a part of daily life with the supermarket.
