Question 1

What does NumHarvest do?

Accepted Answer

NumHarvest generates large lists of country- and carrier-formatted mobile numbers in seconds. Pick a country and network, choose a quantity (up to 500,000 per batch), and download the result as a .txt file.

Question 2

How does pricing work?

Accepted Answer

Flat rate: $1 per 20,000 numbers. Internally, 1 USDT tops up your wallet with 1,000 credits and each number costs 0.05 credits (1 credit per 20). You only pay for what you generate — no subscriptions.

Question 3

How do I add credits?

Accepted Answer

Open the Wallet page to see your personal USDT-TRC20 deposit address. Send any amount of USDT on the TRON network and your wallet is credited automatically once the transaction confirms.

Question 4

Are the generated numbers guaranteed unique?

Accepted Answer

Yes. Every number we produce is recorded with a global uniqueness constraint, so no phone number is ever generated twice across the entire platform — not within a batch, not across batches, not across users.

Question 5

Which countries and networks are supported?

Accepted Answer

50+ countries and 200+ carriers covering Africa, Europe, the Americas, and Asia. You can pick a specific carrier (e.g. MTN, Verizon) or leave the network filter blank to mix all carriers for a country.

Question 6

Can I download my batches later?

Accepted Answer

Yes. Every batch is saved to your private storage and listed on the History page. Re-download any batch as a .txt file at any time — links are signed and scoped to your account.

Question 7

What happens if a generation fails halfway?

Accepted Answer

Your credits are automatically refunded. If the server can't complete the batch (for example, a network pool runs out), it rolls back the debit and surfaces a clear error message — you're never charged for a failed run.

Question 8

What can I legally use the numbers for?

Accepted Answer

NumHarvest is built for QA, load testing, fraud research, data engineering, and academic work. The numbers are format-correct but not live-validated. Do not use them for spam, unsolicited marketing, or anything that violates local telecom regulations.
