Frequently Asked Questions

What file formats are supported?

CSV, TSV, Excel (.xlsx and .xls), and OpenDocument (.ods). Files can have up to 20,000 rows.

Do my addresses need headers?

No. Our AI analyzes your data and detects which columns contain address, city, state, and zip — even without headers. You can also upload single-line addresses like '123 Main St, Springfield, IL 62704'.

What about combined fields?

We handle combined city/state/zip fields, single-line full addresses, and other non-standard layouts. The AI detects these patterns and maps them correctly.

How accurate is the verification?

Addresses are verified against USPS postal data. Results include Zip+4 codes and delivery point barcodes (DPBC) — the same data used for bulk mailing.

What are the add-ons?

After verifying your addresses, you can optionally add geocoding (latitude/longitude) and driving distance/time calculations. These use the corrected addresses for maximum accuracy.
