The service and operator
The NumDetect operating team provides this service. The service provides phone and email account signals through a web dashboard and an API. The available products, input types and countries are those shown in the current product list.
Accounts and credentials
You are responsible for the account and API keys you use and the data you submit. Keep credentials private and notify support if you suspect unauthorized use. Do not share access in a way that bypasses service limits.
Checks and results
Every check uses real check services and may incur a charge. Review the selected products, country coverage and cost before you run a check or submit a list. A result reflects the answer of the selected product at the time of the check; unknown means no conclusive answer.
Balance, holds and charges
Charges are calculated per input and product from the current price list. Single checks use the real-time price: conclusive positive and negative answers are charged; unknown and failed single checks are not. In a bulk list each country × product (each product for email lists) uses the bulk price and is billed for at least its minimum count. When you submit a list we hold its cost. A part that completes is charged its whole hold, max(valid unique rows, minimum) × the bulk price, including rows without a conclusive result; a part that fails, times out or is cancelled before it starts is not charged and its hold returns to your balance. Invalid, duplicate and unsupported items are not charged.
Top-ups and billing questions
Top-ups use fixed plans with no fees: $19.90; $69.90 for $73.90 of credit; $199.90 for $219.90; $499.90 for $599.90. Pay by card, USDT (TRC20) or other stablecoins. Payment confirmation from the provider, not a browser success page, determines crediting. Contact support about payment errors, refund requests or an invoice; these requests are handled individually rather than through an automatic invoice or refund feature.
Cancellation and unfinished work
Cancellation stops work not yet dispatched, and groups not yet sent are not charged. Groups already accepted may continue; a group whose batch then completes is charged in full. When the task finishes, the rest of the amount held for it returns to your balance. If a request or submission is uncertain, inspect the existing task before trying again; do not assume a timeout means nothing was processed.
Permitted use and result limits
Use only data you are entitled to process. Do not use the service for spam, harassment, unlawful surveillance, unauthorized access or attempts to bypass safeguards. Registration and Business signals do not prove identity, ownership, consent, recent activity or guaranteed message delivery. Do not treat unknown as a negative answer or use a signal as the sole basis for a decision with significant effects on a person.
Availability and changes
External platform changes, outages or maintenance can affect coverage and results. Review current availability before starting new work. A previously observed or cached answer is not a guarantee that a later check will have the same result or be free. Contact support about an unexpected outcome, and review the privacy policy before submitting personal data.
