I'm building a location intelligence app and need address and boundary data

Absolutely — for a location intelligence app, you typically need two main data types:
-
Address data
- Geocoded addresses
- Postal/ZIP codes
- Normalized address components
- Reverse-geocoding results
- Points of interest if relevant
-
Boundary data
- Country/state/county/city boundaries
- Postal code polygons
- Neighborhoods, census tracts, districts
- Custom sales territories or service areas
- Administrative or statistical boundary layers
Good sources to consider
- OpenStreetMap / Nominatim / Overpass
- Good for broad coverage and open data
- Address quality varies by region
- Google Maps Platform
- Strong geocoding and place data
- Paid, usage limits apply
- Mapbox
- Good geocoding and tiles; easier developer experience
- HERE / TomTom
- Strong enterprise-grade geocoding and routing
- US-specific public data
- TIGER/Line shapefiles from the U.S. Census Bureau
- Great for admin boundaries
- Commercial boundary providers
- Precisely, Boundary.AI, Zipatlas, SafeGraph-like vendors, etc.
- Useful when you need clean, ready-to-use polygons
What to decide first
- Geographic coverage: country, region, or global?
- Freshness: how often does data need updates?
- Accuracy requirements: rooftop-level vs street-level?
- License constraints: open vs commercial use
- Boundary type: official administrative boundaries or custom business zones?
Typical architecture
- Store boundary polygons in PostGIS
- Use geocoding API for address normalization/geocoding
- Cache results in your own DB
- Index spatial data for fast point-in-polygon and proximity queries
If you want, I can help you with one of these next:
- recommend the best data sources for your region
- design a database schema for addresses + boundaries
- compare open vs commercial providers
- suggest an API architecture for your app
