What is bulk verification?

Bulk verification is the process of checking, standardising and correcting large batches of data all at once

Simply upload a CSV of addresses into our secure portal to leverage Addressfinder’s powerful verification engine in bulk.

Successfully verified addresses will be returned with:

Fixed spelling mistakes and address errors
All mandatory address components present
Standardised formatting for easy deduplication
Added metadata such as Local Government, SA1 and more
Precise geocoding with GPS coordinates

You only pay for successfully verified matches or “lookups”. Start with 1,000 free lookups to see how it works. You can go on to a plan when you’re ready.

Your verified data

Your CSV will be returned with enriched, verified addresses all appended as new columns alongside your untouched original data

You have the flexibility to choose which data sources to verify your addresses against. Each has its strength, for example the NZ Post PAF and Australia Post PAF are best for mail delivery as addresses are officially recognised as deliverable.

Along with the verified address and a full breakdown of its components, your file will include a range of valuable metadata. Where applicable, this includes details such as GPS, Local Government (LGA/TA), Mesh block, SA1, and SA2, ready to enrich your internal systems and insights. View all possible New Zealand and Australia metadata responses.
