TikTok Ads ZIP code targeting
DMA/region targeting native; ZIPs via custom audience workaround.
ZIP targeting
Workaround required
Import format
Native targeting is DMA / county / region. ZIP precision requires a custom audience upload.
Practical limit
Custom audiences support up to 10,000 records per upload.
Where to find it in the UI
Ad group → Audience → Location
Step-by-step: ZipFencer → TikTok Ads
- 1
Export your target ZIPs from ZipFencer.
- 2
Match the ZIPs to your CRM to pull users in those postal codes.
- 3
Upload that user list as a TikTok Custom Audience (email or phone hash).
- 4
In the ad group, target the Custom Audience and pick the broadest matching DMA.
- 5
Layer interest categories on top to keep volume reasonable.
Gotchas to avoid
- TikTok does NOT support direct ZIP targeting — the smallest native unit is DMA.
- For ZIP precision, build a CRM list of users whose addresses fall in your target ZIPs and upload as a Custom Audience.
- TikTok's location resolution skews mobile, so signals are noisier than Meta or Google.
