The example used is a URL. I don't believe there is an equivalent for the address bar. Plenty of other examples exist, but that one is pretty easily reachable by users.
> Customer: "I'm having issues with an order"
> CS: "Can you give me the order number?"
> Customer: "Sure, it's zero two a as in apple five..."
This seems entirely reasonable considering the whole point of TFA is to move away from using UUIDs as unique identifiers for resources in a service.
“Asking the customer to copy/paste the UUID from a URL to send to Support via an email or chat.”
Rather than asking a customer to read it out to you.
