Create a bulk operation by uploading phone numbers, then launch the operation. The API validates each phone number asynchronously with format, carrier, and line type checks.
You can validate up to 20,000 phone numbers per bulk operation. For larger lists, create multiple bulk operations.
Each phone number is validated for format correctness, country pattern matching, carrier identification, line type detection (mobile, landline, VoIP), and number structure.
Each result includes valid status, phone number in multiple formats (local, international, E164, RFC3966), country code, line type, carrier information, and timezone.
Validation is fast - typical processing is 500-1000 phones per minute. A batch of 10,000 phone numbers typically completes within 2-3 hours.
The API accepts numbers in various formats including local, international with +, E.164, and more. Country detection is automatic.
Yes, configure a webhook URL to receive a notification when your bulk phone validation completes with results ready for download.
Once processing completes, use the download endpoint to get all validation results as CSV or JSON format.
Yes. Bulk validation helps suppress malformed or risky numbers before campaign launch, reducing waste and improving contact quality.
Run validation on import, normalize to E.164, filter by line type or country rules, and re-validate stale lists periodically.
