Google Marketing Platform VS ZIP Code API

API for US ZIP, ZIP+4, and Canadian postal code data. One unified endpoint set covers North America — no separate APIs by country or data type.

What it does

Address validation and standardization — production-grade parser with ZIP+4 append, refreshed monthly
Radius search — centroid haversine and true spatial polygon intersection. Returns ZIPs/FSAs within range, with per-result pct_inside overlap percentage for spatial queries
Unified lookup endpoint — accepts US ZIP, ZIP+4, Canadian FSA, full Canadian postal codes, or latitude/longitude inputs
Autocomplete/typeahead — cities, counties, metros, states, FSAs, ZIPs
Point-to-point distance — between any two postal points
Census ACS demographics — 2011–2024, 542 fields per ZIP across income, education, housing, social, and economic profiles
Boundary lookups — Census tracts, congressional districts, state legislative areas, school districts — with computed intersection percentages per ZIP

What makes it different

Licensed commercial data — not commodity or scraped sources
Canadian postal coverage — most peers in this space are US-only
True spatial radius — not just centroid haversine
14 years of historical ACS depth via API — unusual outside of raw Census downloads
One endpoint for all of North America — no country-detection or input-routing logic to maintain on the client side

This person just posted an ad that asked them about DLC they planned on buying. Mario Party Superstars was listed with three other games on the Switch that already have DLC. Is this a good sign that we are getting Mario Party Superstars DLC?
I had assume it was Google itself because I hadn't heard of surveys being part of the AdWords program, but a quick google search showed I was wrong about that. However, I stand by my assessment that the inconsistency between the answers indicate it was an "AI Generated" question. (One option is a named DLC, another is a generic " DLC" answer, and the other two are just the base games' names). Source: over 4 years ago
