Ad Platform Guide
The Trade Desk ZIP code targeting
ZIP, congressional district, and custom polygon — broad geo support.
ZIP targeting
Native
Import format
ZIP CSV or polygon (KML). Supports inclusion and exclusion lists.
Practical limit
Effectively unlimited — TTD handles large custom geo lists natively.
Where to find it in the UI
Ad group → Targeting → Geo → Custom geo
Step-by-step: ZipFencer → The Trade Desk
- 1
Export from ZipFencer as CSV or KML.
- 2
In TTD, open the ad group → Targeting → Geo → Custom geo.
- 3
Upload the file and name the geo set.
- 4
Reuse the same geo set across ad groups via the shared library.
Gotchas to avoid
- TTD's ZIP library updates quarterly. Brand-new ZIPs may not be available for 60–90 days.
- Polygon targeting on TTD bills against the same impression pool as ZIP — no premium for using shapes.
- Some publishers strip geo from impressions — TTD reports 'unknown location' for those.
