About naming an App ID in IOS provisioning portal

I am working for an Australian co开发者_如何转开发mpany atm. When I create an Apple ID in "Provisioning Portal", can i just use prefix as "au.com.mycompany.appname" instead of "com.mycompany.appname". Our company do not have a ".com" website. I got questions about:

1. What's different between "com.mycompany.appname" and "au.com.mycompany.appname"

2. Will this cause me any trouble in the future development, like in-app purchase, distribution or push notification service?

Thanks a lot.

Yes. You could even use "somethingWithNoDotAndNotEvenYourCompanyName", as long as it's unique. The "com.company.product" is only a recommandation.

I myself use "ca.mycompany.product" without any problem.

You can use whatever string you want. au.com.mycompany is good if you own the domain name, because that (sort of) guarantees no one else will use it. The examples start with com but that's certainly not necessary.
