How to control fees for number screening? First coarse sieve and then fine sieve, explain the cost dismantling in one go

When overseas customer acquisition teams use platforms such as Telegram, WhatsApp, and Zalo for private domain promotion, number screening is an indispensable part. However, when many teams first invested, they submitted a large number of numbers for comprehensive testing at once, only to find that only a few qualified numbers were available and the budget was quickly exhausted. Behind this phenomenon of out-of-control costs is often not because the screening numbers themselves are too expensive, but because there is a problem with the screening strategy.

This article will dismantle a core cost control idea: coarse screening first, then fine screening. From number segment generation, cross-platform activation detection, to activity and gender-specific screening, we will sort out an executable hierarchical cost control path for you. At the end of the article, a quick checklist will be compiled to facilitate your direct reference in actual tasks.

Why are your number screening costs always getting out of control?

A common problem among many teams is that after obtaining a batch of mobile phone numbers, they directly conduct a “full in-depth test” at once - simultaneously testing whether Telegram is opened, whether it is active, whether they are male or female, and their age. After the test was completed, it was found that 90% of the numbers were simply empty numbers, and all the money spent on high-precision testing was wasted.

Three major pitfalls of one-time full-scale testing

1. Invalid numbers consume high budgets: Suppose you purchased 100,000 numbers, 60% of which are non-existent empty numbers or numbers that have not been registered on any platform. If you directly submit the activity + gender test, all the test fees for the empty number will be wasted.
2. Detection type mismatch: Not every number requires age and gender identification. Some scenarios (such as group public notifications) only require activity judgment and do not require gender orientation. However, all costs will be superimposed on a one-time full test.
3. Difficult to locate the quality of the number segment: After a one-time large-scale inspection, only an overall pass rate can be obtained. It is impossible to accurately determine which country and which number segment have higher quality numbers. The next purchase will still be blind.

The core formula of cost control: effective lead cost = total cost ÷ number of qualified numbers

If you understand this formula, you can understand why “coarse screening first” can save money. Assuming that the total cost is 1,000 yuan, and 2,000 qualified live accounts are obtained through a one-time full test, the effective lead cost is 0.5 yuan/each. If you switch to hierarchical screening, you first spend 200 yuan to filter out 6,000 empty numbers, and then spend 300 yuan to detect the activity of the remaining 4,000 numbers. Finally, you get 2,000 active numbers. The total cost is 500 yuan, and the effective lead cost is reduced to 0.25 yuan/each. The cost is directly halved.

What is the scientific three-round screening process?

The core logic of hierarchical screening is: first use low-cost testing to filter out a large number of invalid numbers, and then gradually invest in high-cost testing to lock in the target group. It is recommended to adopt a three-wheel structure of coarse screen → fine screen → directional screen.

Coarse screening wheel: use global number generation + enable detection to quickly eliminate empty numbers

The sole goal of the coarse screen wheel is to eliminate voids at the lowest cost. The recommended combination of operations is:

• Use the global number generation module (for example, KK-DATA supports 240+ country/region number segment generation) to generate number segments for the target region. This step is free and you can quickly obtain hundreds or even tens of thousands of numbers to be detected.
• Import these numbers and submit an “activation check” (registration status check for Telegram/WhatsApp/Line and other platforms). The unit price for enabling testing is usually lower than active testing and gender testing, and it can efficiently filter out unregistered target numbers.

Fine screening wheel: use activity + gender/age detection to lock in the target group

After passing the coarse screening wheel, the number in your hand has been confirmed to be an “open status” account. Next, based on business needs, submit this batch of numbers for fine screening:

• Activity Detection: For example, specify “users active on Telegram in the past 30 days”. This detection can eliminate “zombie accounts” that are registered but have not been used for a long time.
• Gender and Age Detection: If the business needs to target female users, or users of a certain age group (for example, filtering people around 30 years old through the age field), you can add gender/age detection in this round. Please note that the age field is for reference only and is often used for crowd portrait interpretation, and is not an accurate value at the ID card level.
• Platform-specific ID export: such as tgid, wsid, uid, etc., used for subsequent marketing system access or customized statistics.

After the fine screening round, the remaining numbers become your high-quality lead pool and can be directly exported for the next step of marketing.

How to implement number screening and fee control in 4 steps?

The following steps are directly applicable, with each step emphasizing how to control your budget.

1. Generate or import target number segments: Use the global number generation function (free) to generate number segments in batches based on the country code of your target market (United States +1, Vietnam +84, Indonesia +62, etc.). Or import a CSV file of your own collection of numbers.
2. Submit activation test (coarse screening): Import the generated number segment into the system and select the “activation detection” type. For example, check whether Telegram is activated. After submission, check the estimated cost and make sure the budget is controllable before starting. After the task is completed, the system will only deduct the actual test results.
3. Activity filtering (fine screening) of activated numbers: Export the “activated” numbers from the previous step (pay attention to deduplication), submit a new fine screening task, select “Activity Detection” and the required activity window. The cost of this step is higher than the activation test, but since the number base has been greatly reduced, the total cost is still controllable.
4. Targeted gender/age screening (optional): Based on active numbers, additional gender and age detection is added. This step only applies to scenarios that require strong orientation. Please note that the unit prices for gender and age detection are different, please refer to the real-time price of the console.

How is the cost of number screening broken down?

Understanding cost components will help you set a budget. The following is the cost breakdown matrix of a typical number screening task (assuming 10,000 numbers, activation rate 30%, activity rate 60%, gender detection accounting for 50%):

Stage	Operation	Reference unit price	Number of items to be tested	Estimated cost
Coarse filter	Global number generation	Free	10,000	0
Coarse screening	Tele opening test	Lower unit price	10,000	Less
Fine screening	Tele active detection	Medium unit price	3,000	Medium
Orientation	Tele gender detection	Higher unit price	1,800	Higher
Total	-	-	-	Far less than the full amount

Note: The unit prices in the above table are for reference only. The actual prices for each platform (Telegram, WhatsApp, Zalo, Line, etc.) and detection types are different. Please log in to the console to view the real-time prices. Compared with one-time full-scale testing, the total cost of stratified screening can be reduced by 40% to 60%.

How can pay-by-item and subscription-free models help you save budget?

KK-DATA adopts the “balance recharge + bill deduction” model and does not have monthly or annual subscription packages. This means:

• Pay as you use: Fees will be deducted from the balance only after the task is completed. You don’t need to pay thousands of yuan in advance to buy a package. When you want to test small batches, you only need to recharge a small amount of USDT.
• No risk of waste: If the number segment is of poor quality, you can stop it immediately after rough screening without incurring high bills.
• Transparent task estimate cost: Before submitting any task, the system will display the estimated cost, so you know how much it will cost before you click “Start”.

How to avoid unexpected interruptions when there is insufficient balance?

When submitting a task, the system will verify whether the balance is sufficient. If the balance is insufficient, the task cannot be submitted. The recommended strategy is:

• Estimate the total cost of the task based on the number of numbers you plan to detect (the unit price of each detection type can be seen on the console).
• Use the free number segment to generate and confirm the quality of the number segment before recharging the corresponding amount.
• Recharge uses USDT (TRC20), with a minimum of about 50 USDT. The balance will be automatically updated after the account is received.

How to check the estimated cost of the task? How do I set a budget cap?

When creating a screening task in the console, after importing the number file and selecting the detection type, the system will clearly list the estimated total cost in the task submission confirmation pop-up window. You don’t need to set an additional budget limit - if the estimated cost exceeds your psychological expectations, you can directly cancel the task, adjust the number amount or detection type and resubmit it.

Data deduplication warehouse: a money-saving feature that is often overlooked

Many teams will repeatedly submit the same number between multiple screening tasks, resulting in the same number being detected multiple times and repeated deductions. The Cross-task data deduplication function solves this problem.

When you enable the data deduplication warehouse, the system will automatically memorize the numbers that have been detected. The next time you submit a new task, if the imported number is the same as the record in the warehouse, the system will skip the duplicate number and no deduction will be made.

5 best practices for number screening and fee control

Here is a quick checklist that you can use before each task:

1. Test the quality of the number segment first and then deploy it in batches: Use a small batch of numbers (500~2000) to conduct activation testing first, and confirm that the activation rate of the number segment is ≥30% before large-scale investment.
2. Layered testing, gradient investment: Strictly implement the sequence of “activation testing → active testing → gender testing”, and each step only operates on the qualified numbers of the previous round.
3. Enable data deduplication warehouse: Duplicate numbers across tasks will be automatically skipped to avoid repeated deductions.
4. Export in batches and analyze batch by batch: Do not export all results at once. First, export the qualified numbers for activation and calculate the proportion; then export the active numbers and analyze the activity rate. Data supports decision-making adjustments.
5. Use free number segment generation to reduce ineffective costs: Free generation of number segments can avoid the high procurement cost when purchasing third-party number lists, while ensuring that the number format matches the target market.

FAQ

**Q: How many numbers can be screened in one task? ** Answer: KK-DATA supports up to about 1 million numbers in a single task. However, from the perspective of cost control, it is recommended to split the numbers into small batches of 5,000 to 20,000 by country or number segment, conduct activation testing first, and then conduct in-depth screening of qualified parts.

**Q: Are the unit prices for different platforms (Telegram/WhatsApp/Line) the same? ** Answer: The unit price of each platform and its detection type (activation, active, gender, etc.) is different. The specific price is based on the real-time price of the console. It is recommended to check the estimated cost of the task before submitting to ensure that the budget is controllable.

**Q: I want to test the system first. What is the recommended process? ** Answer: You can try a minimal closed-loop process: first generate 500~1000 target country number segments (free), and then import them into the system for an activation test, which costs very little. After confirming that the activation rate is satisfactory, the activated numbers can be screened for activity or gender. This process can quickly verify the quality of the number segment without wasting budget.

**Q: What should I do if the balance is not used up? Can I get a refund? ** Answer: The balance is recharged in USDT (TRC20), the minimum is about 50 USDT, and fees are deducted according to the item. The balance will not expire and can be retained for a long time for subsequent screening tasks. It is recommended to estimate the recharge amount based on the planned detection volume to avoid idle funds.

**Q: What fields can be exported from the filter results? What formats are supported? ** Answer: Supports exporting in common formats such as CSV and TXT. The export fields vary depending on the platform and detection type, and usually include number, platform status, activity, gender, age, tgid/wsid/uid, etc. The specific export options are subject to the console.
