Ad Platform Guides

ZIP code targeting, by platform

How ZIP and geo targeting actually works on every major ad platform — including limits, formats, and the gotchas nobody documents.

Google Ads

Standard Search, Display, and Shopping ZIP targeting.

Exclusion lists are the only reliable geo lever in PMax.

Same ZIP model as Google, smaller library but cleaner UI.

ZIP-based audiences with a 1,000 ZIP per ad set limit.

Runs through Google Ads — same ZIP targeting, video-first creative.

DMA/region targeting native; ZIPs via custom audience workaround.

Metro/city level only — ZIPs map to surrounding metros.

Enterprise-grade ZIP, polygon, and proximity targeting.

ZIP, congressional district, and custom polygon — broad geo support.

Metro-level targeting with subreddit overlay — no native ZIPs.
