IAB Categories List: Full Content Taxonomy With Codes

Every website that sells ads programmatically has a topic label, such as sports or travel. The industry calls these labels IAB categories. Advertisers use them to find the right content. Moreover, they use them to avoid the wrong one. On this page you will find the full list with codes. In addition, we explain how the categories work and how to use them.

What are IAB categories?

IAB categories are a standard list of content topics. The IAB Tech Lab maintains the list, and its official name is the Content Taxonomy. As a result, the whole industry shares one common language. For example, the code IAB17 always means sports, no matter which platform you use.

The first version has 26 main categories. In addition, each of them has subcategories. For instance, IAB17 is sports, and IAB17-44 is world soccer.

How advertisers and publishers use IAB categories

The codes are a part of programmatic advertising. First, a page loads and the website sends its category to buyers inside the bid request. Then each buyer decides whether the content fits the campaign.

• Targeting. For example, a car brand can buy ads only on automotive content.
• Brand safety. Advertisers also block sensitive topics, for instance IAB25 and IAB26.
• Publisher controls. Likewise, website owners block ad categories that do not fit their readers.
• Reporting. Finally, both sides compare prices by category.

Furthermore, publishers who use header bidding usually set these codes in the wrapper or in the SSP settings.

Versions of the taxonomy

The taxonomy has changed over the years. Version 1 uses the well known codes from IAB1 to IAB26. However, later versions are much more detailed and use new numeric IDs. Still, the old codes did not disappear, because many platforms accept them today. Therefore the tables below show both the old name and the matching name in version 2.

In addition, some old IAB categories have no match in the newer version. The status column shows them as not mapped. In that case, choose the closest active category.

Full IAB categories list

The tables below show the code, the original category name, the new name in version 2 and the status. First, find your main category. Then look for the subcategory that fits best. Also, you can use the search function of your browser to find a topic quickly.

How to use IAB categories on your website

1. First, find the main category that describes your whole website.
2. Next, add one or two subcategories for your main sections.
3. Then enter the codes in your SSP, ad network or header bidding settings.
4. After that, check the labels of sensitive pages. Otherwise brand safety filters may block more pages than needed.
5. Finally, review the labels when your content changes.

Above all, choose honest labels. Buyers compare the declared IAB categories with the real content. Therefore wrong codes can lower trust and prices. For more on trust between buyers and sellers, read our ads.txt guide.

Conclusion

To sum up, IAB categories give advertisers and publishers a common language for content. Many platforms still use the classic codes from IAB1 to IAB26. Meanwhile, newer taxonomy versions add more detail. So bookmark this list and look up a code whenever you need it.
