It's in this page this page - the GA profiles are grouped into an account corresponding to the first part of the UA code (if you've only got access to one GA account you never really see it, but if your Google ID is linked to more than one GA account then there's a select-your-account intermediate page before you can choose the profile to report on).
- dxp:property name=ga:webPropertyId—The web property ID associated with the profile.
- dxp:property name=ga:accountName—The name of the account associated with the profile.
- dxp:property name=ga:accountId—The account ID associated with the profile, used in the tracking code for your web property (e.g. UA-30481-22).
