Or, why have a registry at all? Can't the chip itself hold a few bytes of data for a phone number? I don't know anything about these "chips", but I have to imagine that's possible.

Why would a phone number be useful as a permanent ID for a pet? What if it is rehomed or the owner changes their number? A UUID with a central database or a public/private key with a decentralized database are much better solutions for that.
