Phone Number Active Status Checker

Check phone numbers in bulk for carrier-level active status.

The actor processes 2,000 to 100,000 unique numbers per run. Larger inputs are deduped, then trimmed to the first 100,000 unique normalized numbers. Each number returns one of three statuses: active, inactive, or unknown.

Use it to clean call lists, validate leads before outreach, reduce SMS bounce rates, and keep CRM phone data fresh.

Duplicates are removed before checking, so you pay for unique numbers checked.

Notes

• unknown means the status could not be determined for that number; it still counts as a checked number.
• Uploaded CSV/XLSX files can use common phone columns such as phone, mobile, or telephone.
• onlyActiveNumbers filters output rows, but billing still applies to every checked number.
