Free Global Number Generation with Pay-Per-Screened Number: How KK-DATA Reduces the Trial-and-Error Cost of Overseas Customer Acquisition?

When expanding into new markets, overseas marketing teams often face a core contradiction: uncontrollable testing costs. Bulk purchasing overseas number packages can cost thousands of yuan upfront with no way to verify validity; generating numbers yourself and then checking them one by one means bearing the double cost of generation and verification. Is there a model that allows risk-free generation of massive numbers but only charges for valid results? That’s the value of “free generation + pay-per-screened number.”

This article will break down KK-DATA’s billing logic, feature details, and practical tips to help you flexibly control your budget and reduce trial-and-error costs in Telegram/WhatsApp customer acquisition.

Why “Free Generation + Pay-Per-Screened Number” Solves Overseas Trial Pain Points?

Traditional number service platforms typically adopt two models:

• Full-Pay Model: Generating numbers costs per number, and screening also costs per number—double billing. For users who need to test numbers across many countries/regions, the upfront investment is very high.
• Package Model: You buy a fixed package (e.g., 50,000 checks), use it up, and often generation is billed separately or limited. Unused checks in the package cannot be refunded, offering poor flexibility.

When you want to test Telegram activity in a new market (e.g., Saudi Arabia, Brazil), generating 10,000 numbers might cost tens of dollars, but perhaps only 20% are valid—meaning 80% of the generation cost is wasted. Then screening adds another layer of fees, amplifying the trial-and-error cost.

KK-DATA’s “free generation + pay-per-screened number” model exactly solves this problem:

• Generation Free: Number generation (including random generation, prefix-based generation, and CSV import generation) is completely zero cost, with no limits on count or frequency (maximum ~1 million per batch). You can risk‑free generate massive numbers for your target market.
• Screening Pay‑per‑Number: You only pay from your balance after submitting a screening task and it completes, based on the actual number of successfully screened numbers. Numbers not screened incur no cost.

This model lets you “get the goods for free first, then pay for valid results,” reducing the sunk cost of trial and error to nearly zero.

Current Billing Models of Main Number Verification Platforms (Generation vs Screening)

To see the difference clearly, compare three typical platform billing logics (no specific product names, just pattern analysis):

Billing Dimension	Traditional Full-Pay Platforms	Traditional Package Platforms	KK-DATA (Free Generation + Pay‑Per‑Screened Number)
Number Generation	Charged per number, usually 0.01–0.05/number	Partially free but with limits or frequency caps	Completely free, unlimited
Number Screening	Charged per number, fixed unit price	Deducts from the package count	Charged per number, transparent unit price
Package Binding	No package, but double billing (generation + screening)	Must buy a fixed package; remaining can be refunded? Usually not	No package, pay as you go
Trial Flexibility	Low – generation costs money	Medium – high upfront investment	High – zero generation cost, only charged for valid results

Key Tip: When choosing a platform, always check whether generation is charged and the balance usage rules (e.g., whether withdrawal is allowed, minimum top-up threshold). Some platforms may claim “free generation” but require purchasing a costly package to use screening—watch for such hidden barriers.

KK-DATA adopts pure pay‑as‑you‑go billing, with no subscriptions or package requirements. You can use it after top‑up; the balance is for consumption only, not withdrawable or transferable (see Billing Info).

KK-DATA Global Number Generation Feature Details

Covers 240+ Countries/Regions, Supports Random Generation and Prefix Import

KK-DATA’s number generation module supports:

• Random Generation by Country: Select a target country (e.g., India, Indonesia, USA), and the system automatically generates valid numbers based on that country’s numbering rules.
• Generation by Prefix: If you already know the target country’s prefix (e.g., +1 for USA), you can specify the prefix and generate numbers in bulk.
• Custom Prefix CSV Import: For users with a specific number range (e.g., incomplete numbers from an existing customer list), upload a CSV file and the system automatically completes and generates full numbers.

All generation operations are completely free—no prior top‑up needed. Generated numbers are automatically saved in your account and stored in the “Data Deduplication Warehouse” for batch screening later.

Seamless Pipeline from Generation to Screening

After generating numbers, you can directly select the platform and check type (e.g., Telegram validity check) in the KK-DATA console and submit a screening task. The system automatically reads data from your generated numbers list—no need to manually download and re‑upload. The workflow is:

Generate (Free) → Select Platform/Check Type (Telegram/WhatsApp/iMessage etc.) → Submit Task (shows estimated cost) → Screening completes → Deduct balance → Export results (CSV/TXT)

This “generate → filter → export” pipeline eliminates intermediate data handling, especially suitable for large-scale operations (e.g., generate 50k numbers once and screen them in batches for different platforms).

How “Free Generation + Pay‑Per‑Screened Number” Saves Costs: Three Real Scenarios

Scenario 1: Exploring Emerging Markets (e.g., Middle East, Latin America)

Suppose you want to gauge Telegram user activity in Saudi Arabia but are unsure about the local number pool quality. Traditional approach: Buy a Saudi number package (~0.05/number, 10k numbers cost500) → Spend extra to check activity → If activity is low, the $500 is wasted.

Using KK-DATA:

1. Free generate 20k Saudi numbers (zero cost).
2. Submit “tg valid” check (checks if registered user). Assume unit price ~0.003/number, screening 20k numbers costs ~60.
3. Find only 30% valid (6k valid numbers).
4. Then submit “tg active” check on these 6k valid numbers (e.g., active within 30 days) – spend a small additional fee.
5. Finally, you pay only for valid and active numbers. Invalid numbers cost nothing to generate. Trial cost drops from hundreds of dollars to tens.

Scenario 2: Multi‑Platform Screening Simultaneously (Telegram + WhatsApp + iMessage)

The same batch of numbers might be used for promotion on multiple social platforms. KK-DATA lets you generate once, then submit screening tasks for different platforms separately. For example:

• Generate 10k US numbers (free).
• Check Telegram activity (pay per number).
• Check WhatsApp validity (pay per number).
• Check iMessage availability (pay per number).

Each platform’s check is billed independently, but generation happens only once and is free. Compared to traditional models (where each platform requires buying/generating numbers separately), you directly save the generation cost twice.

Scenario 3: Data Cleaning and Deduplication

Your team may have old number packages accumulated over the years, containing many duplicates or invalid numbers. KK-DATA’s “Data Deduplication Warehouse” can automatically deduplicate during generation, avoiding wasted screening fees. You can import old numbers for free, the system deduplicates automatically, then only screening the unique numbers—every duplicate detection avoided means real cost savings.

Transparent Billing and Cost Control: Details You Need to Know

KK-DATA’s core billing logic:

• Balance Top‑up: Minimum ~50 USDT (TRC20), balance updates automatically after arrival.
• Pay per Number: Fees are deducted only after the actual screening task completes. Generation, deduplication, and export are all free.
• Cost Estimate: Before submitting a screening task, the console shows the estimated cost, so you clearly see the expense.
• Insufficient Balance: If your balance is less than the estimated task cost, you cannot submit the task and need to top up first.

Note that different platforms and check types (e.g., “tg valid” vs “tg active” vs “WhatsApp valid”) have different unit prices. Please refer to the console real‑time prices or the official billing page for exact amounts.

Usage Tips: 4 Techniques to Maximize the “Free Generation” Advantage

1. Test with a small batch first, then scale up: Use free generation to create 1,000–5,000 numbers per country/region, first submit “tg valid” or “WhatsApp valid” checks to quickly gauge the effective number ratio. Markets with an activity rate below 10% can be abandoned decisively, avoiding wasted costs.

2. Leverage activity day filters: In Telegram screening, don’t just do “tg valid.” Further filter valid numbers with “tg active” (specify 7‑day, 15‑day, or 30‑day activity window) to lock in highly active users. Although it adds one extra check, your final customer acquisition conversion rate will improve significantly.

3. Use the Data Deduplication Warehouse: Avoid generating the same numbers multiple times, leading to duplicate screening fees. Generate and store common country number pools once for free, then deduplicate before each screening to ensure the same number is never charged twice.

4. Enable task completion notifications: Bind your Telegram account in the console and enable the notification toggle. You will receive a push message when a screening task completes, making it easy to export results in time, especially for large batches that take hours (e.g., checking 500k numbers).

FAQ

Q: Is KK-DATA number generation really completely free? Are there quantity limits?
A: Yes, number generation is currently completely free, with no limits on frequency or quantity (max ~1 million numbers per batch). All generation operations incur no fees; fees are only charged per number in subsequent screening tasks.

Q: What is the billing difference between KK-DATA and 007data?
A: Both provide number verification services, but billing models differ. Some platforms like 007data charge per generated number or require package purchases, while KK-DATA adopts “free generation, pay‑per‑screened number,” suitable for users who want flexible cost control. Please refer to each platform’s real‑time prices for exact unit costs.

Q: If I generate 100k numbers for free but only screen 5,000, how am I charged?
A: You are only charged for the 5,000 numbers actually submitted and completed in the screening task. The unscreened numbers incur no cost. You can keep the generated numbers in the “Data Deduplication Warehouse” and screen them in batches later as needed.

Q: How is the per‑number price determined? Are prices the same across platforms (Telegram/WhatsApp)?
A: Different platforms (Telegram, WhatsApp, iMessage, RCS) have different detection unit prices, and even within the same platform, different check types (e.g., tg valid vs tg active) have different prices. Please check the real‑time estimates in the KK-DATA console’s billing info or when submitting a task.

Q: Can I withdraw or transfer my balance? What is the minimum top‑up?
A: Currently, the balance is only for consumption and cannot be withdrawn or transferred. The minimum top‑up is ~50 USDT (TRC20), which updates automatically after arrival. We recommend topping up based on your estimated task volume to avoid idle funds.
