How to find the corresponding ADMIN_LEVEL of the DCA (sub region) number for NA?

How do I identify which states or regions (i.e. ADMIN_LEVEL) are included in a North America (NA) DCA folder such as D1, D2, or D11?
=====================================================================================================================================

Symptoms
--------

Customers may experience one or more of the following:

* The extracted North America map content contains folders named D1, D2, D3, etc., but the geographic coverage is unclear.
* It is difficult to determine which states, provinces, or regions belong to a specific DCA (Data Collection Area) folder.
* A customer needs to identify the corresponding ADMIN_LEVEL information for a DCA sub-region.
* A customer cannot determine which geographic area is represented by a directory in a CORE POI XML delivery.
* The relationship between DCA numbering and administrative boundaries is not obvious from the delivered data structure.

Answer
------

To determine the geographic coverage of a North America DCA folder, use the DCA-to-ADMIN_LEVEL mapping reference file associated with the product delivery. The mapping file identifies which countries, states, provinces, or administrative regions correspond to each DCA number.

For example, DCA_1 (folder D1) contains data for California and Nevada. The reference mapping also provides additional information for ADMIN_LEVEL 3 and ADMIN_LEVEL 4 regions where applicable.

Root Cause
----------

North America content products, including certain CORE POI XML deliveries, are organized into DCA-based sub-regions. Folder names such as D1 through D11 represent internal geographic partitions rather than explicit state or province names. Because the directory names do not contain human-readable geographic information, the covered regions cannot be identified from the folder name alone.

Impact
------

Without the DCA mapping reference:

* Data validation may be difficult.
* Regional content extraction can be inaccurate.
* Customers may incorrectly assume the coverage area of a DCA folder.
* Geographic analysis and troubleshooting can take longer than expected.

Recommended Action
------------------

1. Locate the DCA-to-ADMIN_LEVEL mapping reference provided with the product documentation or delivery package.
2. Identify the required DCA number (for example, D1, D2, D3).
3. Use the mapping to determine the corresponding countries, states, provinces, and available lower administrative levels.
4. Verify the identified geographic region before processing or distributing extracted content.

Expected vs. Unexpected Behavior
--------------------------------

### Expected Behavior

* Data is delivered in DCA-based folders such as D1 through D11.
* Folder names represent geographic partitions rather than state names.
* Geographic coverage is determined using the DCA mapping reference.

### Unexpected Behavior

* Assuming a DCA folder directly identifies its geographic coverage without consulting the mapping reference.
* Treating DCA folder names as state, province, or country identifiers.
