How Bulk Address Verification Works

Bulk address verification checks many rows at once and returns result fields that help you decide which addresses are usable, which need review, and which could not be matched clearly.

Bulk Address Verification vs. Address Validation

Use bulk address verification when you need to confirm whether many rows can be matched to real-world address data. Use address validation when your main goal is checking missing fields, formatting issues, and quality warnings before using a list.

What does a bulk address verification tool check?
It checks whether address rows can be matched to real-world address data and returns result fields that help you review matched, partial, and unmatched rows.
What file formats can I upload?
Upload XLSX, CSV, or TXT files, or paste address rows directly into the tool.
Can I verify international address lists?
Yes. Include a country column when possible, or choose a default country before running verification. This helps the tool return clearer matches for international address data.
Are original columns preserved in the download?
Yes. Your original columns stay in the CSV next to the verification output, so IDs, customer references, notes, and source fields remain available.

The row remains in the output with empty or partial verification fields and notes that explain why it should be reviewed.
