What is Cloudmersive Address Validation?
Cloudmersive Address Validation APIs normalize, parse, and validate international street addresses, cities, countries, and unstructured address strings, returning validity plus latitude and longitude when supported. They sit inside Cloudmersive's Validate portfolio alongside email, phone, VAT, and IP checks, with shared subscription plans and optional managed on-premise deployment for compliance-heavy buyers.
Key features
Street Address Validation
POST structured international addresses; returns ValidAddress flag and geocoordinates when valid.
Address Parse (NLP)
Parse free-text address strings into formatted components across global address norms.
Normalize
Standardize street address components beyond a simple valid/invalid response.
City and Country Validation
Validate city/state combinations and ISO 3166-1 country codes including EU membership flags.
Multi-Language SDKs
.NET, Java, Node.js, Python, and other clients against api.cloudmersive.com.
Portfolio Pricing
One API key and monthly call pool across all Cloudmersive APIs—not address-only SKUs.
Deployment Options
Public cloud, managed single-tenant instances, on-premises, and government cloud regions.
