Bulk Phone Number Validation API & Carrier Lookup

Validate, parse, normalize, and enrich phone-number lists worldwide. Returns format validity, country, carrier metadata, line type (mobile/landline/VoIP/toll-free), timezone, geographic metadata, and E.164/international/national formats.

Built on Google's libphonenumber metadata — the same numbering-plan library used by Android and many communications products. Results do not establish live reachability, current ownership, consent, or successful OTP delivery.

What you get

For each phone number:

• Validation: Whether the number is possible and valid under published numbering-plan metadata
• Formatting: E.164, international, and national formats
• Country & Region: Country calling code and ISO region code
• Line Type: Mobile, fixed line, VoIP, toll-free, premium rate, etc.
• Carrier: Numbering-plan carrier metadata when available (optional; portability can make it stale)
• Geocoding: Geographic location (optional)
• Timezone: Associated timezones (optional)

Use cases

• CRM cleanup: Validate and standardize phone numbers in your database
• Lead-list hygiene: Flag malformed or structurally invalid numbers before outreach
• Compliance support: Add line-type metadata for review; do not use this output alone as a consent, TCPA, or do-not-call determination
• Data enrichment: Add country, carrier, and type metadata to phone lists
• International formatting: Convert local numbers to international dial format

Important interpretation limits

• valid and isPossibleNumber are structural numbering-plan checks, not proof that a subscriber can receive a call or message.
• Carrier and geography fields are metadata and can be missing or stale after number portability.
• This actor does not send OTPs, contact subscribers, verify ownership, check consent, or query live carrier/HLR data.

Pricing

$0.0005 per validated number ($0.50 per 1,000 results). The five-number default demo costs $0.0025. No API key, start fee, or external account is needed. Buyer-set charge limits are applied at this live per-result rate.

Large lists are written in bounded dataset batches so the advertised bulk workflow does not exceed Apify's per-request payload limit.

Supported formats

Accepts any phone number format: +1-555-123-4567, (555) 123-4567, 5551234567, +44 20 7946 0958, +49 30 123456, etc. Numbers without a country prefix are parsed using the defaultRegion setting (defaults to US).
