Question 1

What does NumHarvest do?

Accepted Answer

NumHarvest harvests mobile numbers from any country in the world and validates them across every major messaging platform — WhatsApp, Telegram, Signal, Viber, iMessage, and Facebook Messenger. Pick a country and carrier, choose a quantity (up to 500,000 per batch), and download per-platform lists as .txt.

Question 2

How does pricing work?

Accepted Answer

Flat rate: $1 per 20,000 numbers, harvesting and multi-platform validation included. Internally, 1 USDT tops up your wallet with 1,000 credits and each number costs 0.05 credits. No subscriptions — you only pay for what you generate.

Question 3

How do I add credits?

Accepted Answer

Open the Wallet page for your personal USDT-TRC20 deposit address and unique tag. Send USDT on the TRON network and your wallet is credited automatically once the transfer confirms.

Question 4

Are the harvested numbers guaranteed unique?

Accepted Answer

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

Question 5

Which countries and carriers are supported?

Accepted Answer

Any country in the world, backed by real regulator-issued carrier prefixes for 200+ networks across Africa, Europe, the Americas, Asia, the Middle East, and Oceania. Filter by a specific carrier (MTN, Airtel, Vodacom, Verizon, Jio…) or mix all networks for a country.

Question 6

How does the WhatsApp & multi-platform validation work?

Accepted Answer

Every harvest is followed by an AI validation scan that estimates presence across WhatsApp, Telegram, Signal, Viber, iMessage, and Facebook Messenger. The model blends per-country adoption data with deterministic per-number signals to bucket your list, and each platform bucket is downloadable separately — so you can target the right audience on the right channel.

Question 7

Can I re-download my batches later?

Accepted Answer

Yes. Every harvest and its per-platform validated splits are saved to your private storage and listed on the History page. Re-download any batch — WhatsApp, Telegram, Signal, Viber, iMessage, Messenger, or the full list — anytime.

Question 8

What happens if a harvest fails halfway?

Accepted Answer

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

Question 9

What can I legally use the numbers for?

Accepted Answer

NumHarvest is built for QA, load testing, fraud research, data engineering, academic work, and outreach targeting research. Numbers are harvested in correct country/carrier format and platform-scored via adoption models — not live-queried against each platform's private servers. Do not use them for spam, unsolicited marketing, or anything that violates local telecom or platform regulations.
