Why validate an address list?

Bad addresses cost money quietly: returned mail, failed deliveries, duplicate CRM records and geocodes that land in the wrong place. Dedicated validation APIs charge $50+/month for the first thousand lookups. This tool runs each address through the same multi-provider engine as our geocoder, standardises it, and tells you honestly how confident the match is — free for everyday list sizes.

Validate directly in your spreadsheet

If your list lives in Google Sheets, skip the copy-paste entirely: the free InstaMaps add-on gives you =CLEAN_ADDRESS() for standardisation, =GEOCODE() for coordinates, and =POSTCODE()/=CITY() to fill missing columns — living formulas that keep the list clean as it grows. There are also ready-made templates with the formulas already in place.
