IAB content taxonomy mapping: Version 1.0 to 2.2
The Trade Desk has updated its content taxonomy categories to support both IAB 1.0 and IAB 2.2. If you are using the IAB 1.0 taxonomy for blocked categories (bcat), use the following tables to map these categories to IAB 2.2 and find the correct values for the bcat field.
To use these tables, look up the desired IAB 1.0 ID, then find the corresponding IAB 2.2 ID in the same row. Keep in mind that the IAB 2.2 taxonomy is more granular than the IAB 1.0 taxonomy. Some categories from the IAB 1.0 taxonomy map directly to a single category in IAB 2.2 (1:1 relationship), while others map to multiple categories (1:N relationships). For example, to block the "Arts & Entertainment" category, instead of using the IAB 1.0 ID of IAB1, use any or all of the IAB 2.2 IDs, such as 156 and 158 for musicals and nightclubs.
The categories in the following tables are organized first by IAB 1.0 ID in ascending order, and then alphabetically based on the IAB 2.2 category name. This reference excludes IAB24 and IAB25, which are uncategorized and unavailable for use, and includes IAB27, a custom category for medical health not in the original IAB definition.
TIP: To quickly find your categories, enter keywords or the IDs in the search function of your web browser.
