Without creating a userdefined region, what is the most specific group a topology record can identify?

City is not a built-in geographic level in GTM topology records; it requires a user-defined region to represent city-level granularity.

Country is a valid topology level but is less specific than state/province, which sits below country in the built-in hierarchy.

Continent is a valid topology level but is the broadest geographic grouping, not the most specific.

GTM topology records use a built-in geographic hierarchy of continent, country, and state/province. State/province is the deepest level natively supported - no user-defined region is required to use it. To go more granular than state/province, an administrator must manually create a custom user-defined region.

'Region of country' is not a distinct built-in topology level; it would require a user-defined region to implement.
