Results include current registration status, registered business name and address and tax metadata. Fonoa can search for a tax number by company name, validates up to 50,000 records in one batch, and uses fuzzy matching to flag mismatched, incomplete or outdated VAT data^[15]. Named customers on the page include Wellhub, Remote and Coda; Wellhub is quoted as reporting 33% fewer tax ID validation tickets^[15], a figure supplied by the vendor.
