Instant Address Assurance: GeoVerifySingle’s One‑Click Validation

Overview

GeoVerifySingle is the one‑off address validation endpoint in the CDXGeoData suite. Given a single free‑form address string, it returns a fully standardized, deliverable address—including USPS ZIP+4™ correction—and geospatial coordinates, all in one lightweight call.

Key Business Use Cases

1. Real‑Time Checkout Validation

Validate and auto‑correct customer addresses at checkout to reduce failed deliveries and returns. Block invalid entries and prompt users to fix typos before order submission.

2. Lead Quality Enhancement

Ensure your CRM or marketing automation only stores deliverable addresses by validating individual leads on entry, improving direct‑mail ROI and reducing bounce rates.

3. Fraud Detection & KYC

Integrate GeoVerifySingle into onboarding flows to verify address authenticity in real time—flagging PO boxes or invalid addresses that may indicate fraudulent activity, and confirming geocoordinates fall within expected regions.

Getting Started

1. Retrieve your API key by signing up at the CDXGeoData portal.
2. Decide on your delimiter—use commas, pipes, or any character(s) not found in your address lines.
3. Invoke GET /api/geoverifysingle with key, address, delimiter, and format parameters to receive a sanitized address, ZIP+4™, and coordinates in one go.
