Summary

Addrex Address Validation API checks U.S. addresses and returns standardized fields, match codes, confidence scores, and coordinates. It supports both API requests and spreadsheet cleanup. For batch work, users can upload CSV or Excel files, have address columns detected, process them, and download cleaned data with output fields appended. Cleanup can expand abbreviations, correct typos, parse grid-style inputs, and add ZIP+4 when a match is available. The API accepts a one-line address or structured fields and returns JSON with validation status, confidence, standardized fields, and changes. Free Beta is listed at 0.00 USD per free and allows 10,000 address lookups per month; it requires email verification and excludes autocomplete. Paid plans start at 39.00 USD per month. Autocomplete is limited to paid plans. Real-time API data is not retained beyond a request, while batch files default to seven days and may be deleted sooner. Addrex does not claim USPS DPV or CASS certification.
