Terms of Service
These terms describe permitted use, balance usage, customer responsibilities, and service availability for NumDetect.
Last updated: July 20, 2026
1. Service use
NumDetect provides asynchronous bulk checks: upload a number file, poll the task, and download the result. Each task takes 1,000 to 100,000 numbers; files outside that range are declined before any charge.
2. Balance
Permanent balance is charged per completed validation according to the selected product. 30-day plan balance is spent first and expires after its current 30-day period. Failed or undetermined checks return the reservation to the same wallet. Permanent top-ups are one-time purchases; 30-day plans renew automatically every 30 days until auto-renewal is turned off.
3. Customer responsibility
Customers are responsible for lawful use of phone validation data and protecting their API keys.
4. Acceptable use
Do not use the service to facilitate spam, harassment, unlawful surveillance, credential sharing, attempts to bypass limits, or interference with the service. A validation result does not grant permission to contact a person.
5. Result interpretation
Results describe the phone-number registration status returned when a task is processed. They are not proof of identity, ownership, consent, or future availability and should not be used as the sole basis for a high-impact decision.
6. Availability
Results may be affected by external service availability. Maintenance or check-service errors may temporarily prevent a response.
