‡ Only the region portion is currently used.
The -rg-abzzzz is ignored because AB is invalid;
if it were -rg-ustuvxy, it would not be ignored because US is valid.
The table below shows when the region portion is valid or not.

| Subdivision Code | Region | -rg used? | Comment |
| --- | --- | --- | --- |
| usut | US | Yes | Both the region portion (US) are valid and the subdivision portion (Utah) are value. |
| usabc | US | Yes | The region portion (US) is valid, but the subdivision portion is not. |

1. If there is a valid -ms value then let USM be the corresponding value in column 2 of the table below.
Otherwise FR is not used. In either case continue with step 2.
2. If there is a valid -rg region, let R be that region, and go to Compute the category.
3. If there is a valid region in the locale, let R be that region, and go to Compute the category.
