If there weren't standards, how could readers parse them? There are lots of different symbologies (ways to encode data), each with its own benefits and limitations. The one most familiar to U.S. consumers is the UPC code. Most pro sports and event tickets also use barcodes. Ticketmaster and Tickets.com use different symbologies from each other.
