Pay-per-Verification Number Screening Explained: Full Process of Balance Top-Up, Per-Item Deduction, and Cost Estimation

When overseas marketing teams batch-screen Telegram or WhatsApp numbers, cost control is often their top concern. Traditional subscription plans come with fixed monthly expenses—unused quotas go to waste, and exceeding limits requires additional payments. The pay-per-verification number screening model is completely different: no monthly or annual fees. You top up your balance, and each task deducts fees only for successfully verified numbers—pay only for what you use. How does this mechanism work? How are costs estimated? What money-saving tips exist? This article breaks down the entire process from top-up to deduction, helping you fully master the complete workflow of pay-per-verification number screening.

What is Pay-Per-Verification Number Screening? — From Basics to Core Logic

Pay-per-verification number screening is a billing model that charges based on actual verification results. Users first top up their account balance (e.g., via USDT), then create a screening task. After the task completes, the system deducts from the balance the number of successfully verified numbers × the corresponding unit price. Numbers that are not successfully verified or that fail verification are not charged.

Compared with common SaaS subscription plans, this model’s core advantages are flexibility and cost controllability:

Zero monthly fee, pay on demand: No paying for unused quotas.
Transparent estimation: Before submitting a task, the system displays an estimated cost, avoiding unexpected charges.
Incremental replenishment: Top up anytime when balance is low—no need to wait for a plan to expire.

Pay-Per-Verification vs Subscription Plans: Which Suits Your Overseas Team Better?

Dimension	Pay-Per-Verification Number Screening	Traditional Subscription Plan
Payment method	Top up balance, pay per item	Fixed monthly/annual fee
Quota management	Balance decreases with usage, no expiration	Quota resets or accumulates monthly
Cost flexibility	Pay for what you use, low cost during low usage	Fixed monthly expense, waste or shortage when usage fluctuates
Best suited for	Small/medium teams, periodic high-volume pushes, trial periods	Long-term, stable high-frequency usage (but usually inflexible)

For most overseas B2B teams, pay-per-verification number screening offers better value—especially when task frequency is irregular or the number of numbers varies greatly, avoiding paying for unused capacity.

How Much Does One Verification Cost? Cost Composition and Platform Differences

The per-verification price depends on three factors:

Platform: Telegram, WhatsApp, iMessage, RCS, etc. have different verification costs and unit prices.
Verification type: Simply verifying “active” differs in price from verifying “activity + gender”—the latter consumes more resources.
Country/region of the number: Some operators have higher thresholds, which may slightly affect unit prices.

For specific unit prices, please refer to the real-time prices on the console or the official billing page: https://kkdata.cc/billing/

Cost estimation formula:

Estimated total cost = Total number of numbers to verify × Unit price of the selected verification type
Final actual deduction = Number of successfully verified (valid results returned) numbers × Unit price

(Numbers that fail verification are not counted toward charges)

Balance Top-Up: USDT Top-Up Process and Precautions

Pay-per-verification number screening relies on your account balance to execute tasks. The top-up method is USDT (TRC20), with a minimum of approximately 50 USDT. Once received, the balance updates automatically—no manual approval needed.

Detailed Top-Up Steps

Log in to the console (https://app.kkdata.cc/) and navigate to the “Top Up” page.
Generate a deposit address: The platform will generate a unique TRC20 address. Make sure the address is correct and keep a screenshot.
Use your wallet (e.g., MetaMask, TP Wallet) to transfer USDT to that address, selecting the TRC20 network.
Wait for confirmation: Once the on-chain transaction reaches sufficient confirmations, your balance will automatically increase. Typically arrives within a few minutes.

Security Reminder

What Happens When Account Balance Is Insufficient? Task Submission and Balance Lock Mechanism

Before submitting a screening task, the system checks whether the account balance ≥ the estimated cost. If the balance is insufficient:

The task cannot be submitted; the system prompts an insufficient balance.
You must top up to a sufficient balance before you can create the task.
For tasks that have been submitted but not yet executed, the system will lock the balance again before starting; if the balance is consumed by other tasks during execution, the task may be paused and requires a top-up to resume.

Therefore, it is recommended to ensure sufficient balance before submitting large tasks, or submit them in batches.

Screening Task Cost Estimation: How to See the Final Cost Before Submission?

Before submitting a screening task, the system automatically calculates the estimated cost and displays it on the task creation page.

Cost Estimation Hint

On the task submission page, the system displays the “Estimated Cost” and “Current Balance.” Please ensure the balance is sufficient before submitting. The estimated cost is for reference only; the actual deduction is based on the number of successfully verified numbers after the task completes.

How to View Detailed Estimates?

In the console, select “New Screening Task.”
Upload numbers (or use the global number generation feature).
Select the verification platform and type (e.g., Telegram activity verification).
The system immediately displays:
- Total number of numbers
- Estimated cost (total numbers × unit price)
- Whether the current balance is sufficient
After confirming, click submit.

This way, you know exactly what you will pay before any deduction occurs, avoiding overspending.

Where Are Per-Item Deductions Applied? — Full Deduction Process Breakdown

Understanding each step of the deduction process helps you better manage your budget.

Submit task: The system checks if the balance is sufficient to cover the estimated cost. If yes, it enters the queue; otherwise, you are prompted to top up.
Execute verification: The platform starts verifying each number one by one. Numbers that fail verification (invalid, unregistered, etc.) do not generate charges.
Task completes: All numbers have been verified.
Deduct balance: The system calculates the number of numbers that successfully returned verification results × unit price, and deducts the corresponding amount from the balance.
Balance change notification: If Telegram notifications are enabled, the system automatically sends the task result and deduction info.

Query deduction records: On the “Finance” or “Billing” page, you can view details of each deduction, including task ID, number count, successful count, unit price, deduction amount, and time.

Data Deduplication Warehouse: How to Avoid Repeated Charges?

If the same number is submitted in different tasks, it would theoretically be charged again. However, pay-per-verification platforms usually provide a data deduplication warehouse—it automatically records all successfully verified numbers. When the same number is submitted again, it is skipped directly and not charged again.

Usage Suggestions:

After generating or importing numbers each time, first deduplicate the number list (the platform supports cross-task deduplication).
Before submitting a screening task, get into the habit: “deduplicate → check estimated cost.”
The deduplication warehouse data is cross-task. Even if you verified a number in a previous screening task, submitting it again will not incur a repeated charge.

Money-Saving Tip

After generating or importing numbers each time, clean them through the “Data Deduplication Warehouse” before submitting a screening task. This avoids repeated charges for the same number—recommended as a routine practice.

Common Billing Misconceptions and Pitfall Avoidance Guide

Are Numbers That Fail Verification Charged?

No. The system only charges for numbers that successfully return verification results (e.g., number is active, status, gender info, etc.). Numbers that fail (invalid, unable to connect, timeout, etc.) are not counted toward charges.

How to View Balance Change Details?

Log in to the console, go to “Finance” → “Balance Change Records.” You can filter by time range or task to see detailed information on each top-up and deduction.

Other Common Misconceptions:

“Submitting a task deducts the full amount immediately”: Wrong. Deductions only occur after the task completes for successfully verified numbers; failures are not charged.
“When balance is insufficient, the task deducts half”: Wrong. Tasks cannot be submitted if balance is insufficient.
“All verification types have the same unit price”: Not necessarily. Activity verification is usually more expensive than simple activation verification. Double-check before submitting.

Cost Optimization Suggestions: Make Every Penny Count on Valid Numbers

Leverage free number generation first: The global number generation feature is free. Generate a pool of numbers for your target country first, then select from them for screening—avoid buying expensive external data.
Deduplicate first, then screen: Use the data deduplication warehouse to filter out already verified numbers and reduce repeated charges.
Choose verification types based on need: If you only need to know whether a number is active (registered), don’t select “activity + gender”—the latter is more expensive.
Submit large tasks in batches: Avoid submitting a huge dataset at once to prevent a large portion of your balance being locked, which could affect other tasks.
Enable task completion notifications: Receive task completion messages via Telegram to adjust subsequent plans in a timely manner.

Frequently Asked Questions

Q: Is the pay-per-verification model suitable for users with a small budget?

A: Yes. There are no subscription thresholds. The minimum top-up is about 50 USDT. Pay as you go, and you can top up anytime. It is friendly for small budgets.

Q: If my balance is insufficient after submitting a task, can the deduction still proceed?

A: No. Before submitting a task, the system checks whether the balance is sufficient to cover the estimated cost. If not, the task cannot be submitted. You need to top up first.

Q: If the same person uploads the same phone number in different tasks, will it be charged repeatedly?

A: The platform has a built-in data deduplication warehouse. Numbers that have already been verified will not be charged again when resubmitted, avoiding waste.

Q: Does the per-verification unit price change frequently?

A: Prices are based on real-time display in the console. The platform may adjust from time to time. It is recommended to check the latest unit price before submitting a task.

Q: Are numbers that fail verification (invalid/non-existent) charged?

A: No. The system only charges for numbers that successfully return verification results (e.g., active, registered, etc.). Failed numbers are not charged.
