What FoneSwift Bulk Phone Validator is

FoneSwift Bulk Phone Validator is a web tool for checking and standardizing phone numbers in contact lists. Upload a CSV or XLSX file, and the tool finds the phone number column automatically. It checks number formats for more than 200 countries, identifies the country, carrier, and line type, and can convert numbers to E.164 format. Lists can include numbers with or without country codes.

Results show valid or invalid status, country, carrier, line type, and formatted numbers. Filter the results and download them as CSV or Excel for import into a CRM or database. FoneSwift lists Salesforce, HubSpot, Zendesk, Slack, Zapier, and Make among its integrations; its REST API and webhooks support custom workflows. The free tool handles up to 1,000 rows or 10 MB per upload, and the page says uploads, validation, and downloads are available without signup. FoneSwift says uploaded numbers are deleted after validation and not retained. The free checker assesses format and line type, while real-time network reachability checks are directed to the enterprise platform. Paid plans start at $15/user/mo and are described as offering larger uploads, API access, real-time HLR lookup, and automated list-cleaning workflows.

Who it suits

It suits teams cleaning CRM contacts, checking lead lists, preparing sales or marketing campaigns, or standardizing phone data during a system migration. The no-signup web flow is useful for occasional batch checks; teams that need scheduled validation, API workflows, or network reachability checks are directed to enterprise plans.

What to know first

  • Larger uploads, API access, and HLR lookup are on paid plans.

Limits
