Address Verification Tool

The Address Verification Tool helps confirm whether address records can be matched to real-world address data. Upload a spreadsheet or paste rows, map the address fields, and download verification results with formatted addresses, match details, and review notes.

Use it for address verification, international address verification, and global address verification workflows where you need more than formatting. You can verify up to 2,500 addresses for free in the browser; larger datasets can run as paid background jobs.

Upload a fileSelect an Excel, CSV file, or text from your computer
Copy & PasteCopy and paste addresses from a list or table

After uploading your file, map the address fields and run the lookup. The result CSV keeps your original columns and adds verification output so you can review matched, corrected, partial, or unmatched rows.

How Address Verification Works

Address verification compares each row with address data, returns the best available match, and adds details that help you decide whether the address is reliable enough for your workflow.
