Increased Number of Properties and Sub-Properties in an Account
Google Analytics has increased the number of Properties allowed in an account from the previous default value of 100 to 2000 (learn more). This change will allow for more flexibility in organizing properties and removes the need to request an increase from the support team. This change impacts GA4 free accounts.
In addition, a new limit on the number of sub-properties allowed on a property was introduced (learn more). This limit is set at 400; it may be increased via a request to support. These requests will be closely scrutinized and approved on a case-by-case basis. Subproperties are only available in GA4 360, the paid version of Google Analytics.
