Address Validation Tool

The Address Validation Tool helps you check address lists before they are used for shipping, customer records, analytics, or mapping. Upload a spreadsheet or paste address rows, map the address columns, and download results with validation notes, quality details, and cleaned address fields.

Use it when you need an address validation service that works with XLSX, CSV, TXT, or pasted data. You can validate up to 2,500 addresses for free in the browser; larger datasets can run as paid background jobs.

Copy & PasteCopy and paste addresses from a list or table

After uploading your file, map the street, city, postcode, country, and other address columns. The tool checks each row and returns a CSV with your original data plus validation output.

How Address Validation Works

Address validation checks whether each row has enough usable address information, highlights missing or suspicious parts, and returns structured output you can review or import into another system.

Frequently Asked Questions

Is the Address Validation Tool free to use?
Yes. You can validate up to 2,500 rows per run for free in your browser. Larger files can be processed as paid background jobs.
What does address validation check?
Address validation checks whether address parts are present, structured correctly, and can be cleaned into a usable format. Results can include warnings for missing street names, postcodes, cities, countries, or low-quality matches.
What files can I upload?
Upload XLSX, CSV, or TXT files, or paste addresses directly into the tool. Clear column names such as street, city, postcode, and country make mapping faster.
Can I validate international addresses?
Yes. Include a country column when possible, or choose a default country before running validation. This helps the tool apply the right address format and return clearer results.
Are my original columns preserved?
Yes. Your original columns stay in the output next to the validation results, so IDs, customer references, source fields, and notes remain available in the downloaded CSV.
What happens with invalid or incomplete rows?
Invalid or incomplete rows remain in the result file with empty or partial output fields and notes that explain what should be reviewed.
When should I use address verification instead?
Use address verification when your main goal is to confirm whether addresses can be matched to real-world locations, especially across countries.
