Validate Phone Numbers in Bulk — International Format

Validate, format, and enrich phone numbers at scale. Supports all international formats, detects country, region, carrier type, and line type. Outputs E.164 and national format. No proxy needed — pure computation.

What You Can Validate

• Format validation — check if a phone number is valid for its country
• E.164 formatting — normalize to international standard (+country code)
• National formatting — format in local display style
• Country detection — identify country from number prefix
• Line type — mobile, landline, VoIP, toll-free, premium
• Bulk processing — validate thousands of numbers in a single run

Primary Use Cases

• CRM data cleaning — validate and format phone numbers in your contact database
• Lead verification — filter out invalid numbers before SMS or calling campaigns
• Data enrichment — add country, region, and line type to raw phone data
• Compliance — ensure phone numbers meet E.164 standard for APIs like Twilio
• Deduplication — normalize formats to identify duplicate contacts
