In-depth analysis of the sieve number system deduplication warehouse: How to use the deduplication function to avoid repeated deductions

In the daily work of acquiring customers overseas, batch screening of numbers is a necessary step to verify the validity of numbers on platforms such as Telegram, WhatsApp, and Line. However, many teams overlook a hidden cost: The same number is repeatedly detected in different tasks, resulting in wasted balance. This is the problem that the Duplication Warehouse in the Screen Number System wants to solve. This article starts from the actual scenario and breaks down the working mechanism, saving logic and best practices of the deduplication warehouse in detail to help the data operation team spend money wisely.

What is the deduplication warehouse of the screening system? Why it’s critical for cost control

The deduplication warehouse is a data index layer built into the screening system. It records the detection results (number + platform + detection type) of all historical screening tasks. When a new task is submitted, the system automatically compares the list of numbers to be detected with the deduplication warehouse records, skips the number-platform-type combinations that have been detected, and only deducts fees for the undetected parts.

Core Value: Once tested, valid for life. For the same detection dimension under the same account (such as the Telegram activation status of a certain number), you only need to pay once, and no fees will be deducted for subsequent repeated submissions. This mechanism directly reduces the waste ratio in batch screening numbers, and is especially suitable for teams that have a large historical number database and need to repeatedly verify and update.

Basic workflow of deduplication warehouse

1. Generate or import numbers: Prepare the list to be filtered through the global number generation module (supports random generation, number segment generation or CSV import in 240+ countries/regions).
2. Submit screening task: Select the target platform (such as Telegram to activate detection), detection type, and confirm the task.
3. System automatic comparison: After the task is submitted, the system immediately compares the records of all completed tasks under the account in the deduplication warehouse and marks the detected “duplicate number segments”.
4. Skip duplicates and only perform unchecked parts: Actual detection volume = total number of submissions - number of duplicates removed. Deduction amount = actual detection volume × real-time unit price.
5. Update the deduplication warehouse after the task is completed: The newly detected number-platform-type combination is stored in the warehouse and will take effect for the next task.

The entire process is transparent and automated, and users can see the “estimated cost” and “estimated number of duplicate items” on the console before submitting the task.

How does duplicate deduction occur (if there is no deduplication function)

Assuming that there is no deduplication warehouse, the following scenarios will cause repeated deductions:

• The same employee imports the same 10,000 numbers twice to detect Telegram activation → 10,000 numbers will be deducted both times.
• Multiple employees submitted tests separately using the same account, and there were overlaps in the number pools → the overlapping portions were deducted multiple times.
• Resubmit all numbers when the number database is updated regularly → Historically verified numbers will incur charges again.

The deduplication warehouse fundamentally cuts off these wastes. You only need to pay once for each number to be tested in the same dimension.

How deduplication warehouse helps overseas customer acquisition teams save budget

Overseas customer acquisition teams usually face two typical data processing modes:

Mode	Description	Cost without deduplication	Cost with deduplication
Multiple rounds of screening numbers in batches	Screening of 50,000 Telephones in the first phase was opened, 20,000 new ones were added in the second phase and included the 50,000 in the first phase	50,000 invalid detections	Only 20,000 new ones were detected
Multi-platform cross detection	The same batch of numbers are tested separately for Telegram, WhatsApp, and Line activity	Full deduction for each platform	Duplicate removal for each platform, no duplication across platforms
Multi-person team collaboration	Operation A and Operation B submit tasks separately, and some numbers overlap	Multiple deductions for the overlapping parts	The system automatically removes duplicates, and only deducts the overlapping parts once

Actual savings depends on number overlap ratio. If the team uses the same core number pool every day to conduct hierarchical screening of different dimensions (first screening for activation, then screening for activity, and finally screening for gender), the deduplication warehouse can ensure that only one payment will be deducted for the “activation” dimension. Although subsequent activity and gender detection will be charged according to the new type, activation records will not be charged twice.

Collaborative use of deduplication warehouse and other functions

The deduplication warehouse is not an isolated function, it is a cost control hub in the “Generate → Filter → Export” pipeline.

After generating the number, remove duplicates first and then submit the task.

When using the global number generation module to generate a new number segment, it is recommended to first check whether there is coverage through the history of the deduplication warehouse. If the generated number is a completely unfamiliar number, just submit it directly; if the generated number is frequently used in previous tasks, first import it into the warehouse for comparison to avoid inadvertent repeated detection. The generation function of KK-DATA itself is free, so there is no additional cost for this step.

Automatically remove duplicates when multi-tasking is running in parallel

When multiple team members use the same account to submit screening tasks at the same time, the system compares the deduplication warehouses in real time. For example: Operation A submitted 500,000 Telegram activation checks, and the task is still being executed; Operation B submitted 200,000 activation checks for the same number at the same time. B’s task will immediately identify the overlapping part and only deduct fees for the non-overlapping numbers (assuming there are 100,000 overlaps, then B will actually deduct 100,000 numbers). This real-time deduplication ensures zero waste under team collaboration.

Best practices and precautions for using deduplication warehouses

• Check the bill regularly: After each task is completed, check the task details page of the console, which clearly lists the “number of submissions”, “number of duplicates removed”, and “actual number of deductions”. This is more transparent than any verbal promise.
• Focus on the independence of detection types: Deduplication warehouses are judged based on the combination of “number + platform + detection type”. For example, the number +861234567890 has already been tested for Telegram activation. If the Telegram activation of the same number is tested again, the duplicates will be removed. However, if Telegram activity or Telegram gender is detected, due to different detection types, duplicate detection will not be done and charges will be deducted as a new detection. Be sure to understand this rule.

• Storage period and cleanup: The records of the deduplication warehouse will be retained for a long time until the user manually clears them or reaches the storage limit specified on the console (an early reminder will be given once the upper limit is approached). Generally, there is no need to actively clean up, but if there is test data that needs to be cleared, you can do it on the “Deduplication Warehouse” page of the console.
• Not valid across accounts: Deduplication warehouse only works within the same account. If a team uses multiple independent accounts, overlapping numbers will cause repeated deductions across accounts. It is recommended to concentrate the workload under one main account, or pay attention to the multi-account collaboration function that may be launched in the future.

How to view the savings record of the deduplication warehouse?

Log in to KK-DATA Application Console and enter any completed task details page to see:

• Total number submitted
• Number of duplicate items (number of items that the system directly saves for you)
• Actual number of deductions
• Real-time estimated savings (calculated based on current unit price)

For example, if 100,000 items were submitted for testing, the deduplication warehouse identified 30,000 items as duplicates, and 70,000 items were actually deducted. The testing cost of these 30,000 items is what you save through the duplication mechanism. All data can be exported for review.

What is the difference between deduplication warehouse and “pre-detection and screening”? (To prevent conceptual confusion)

Pre-detection and screening (such as preliminary filtering of invalid numbers through number segment rules and national number segment database) occurs during the number generation or import stage, with the purpose of reducing the amount of data entering the formal number screening task. The deduplication warehouse acts in the task execution phase and skips the detected parts based on historical task results.

Features	Duplicate Warehouse	Pre-Detection and Filtering
Trigger timing	After task submission, before execution	Before task submission
Basis	Historical task results for the same account	Number segment rules, country/operator database
Processing object	Detected number-platform-type combination	Invalid or low-frequency number segment
Impact of fee deduction	Skip the inspected part, no fee will be deducted	Reduce the total amount submitted, indirect savings

The two functions can be used in combination: first use pre-detection screening to filter out obviously invalid numbers, and then submit the task to use the deduplication warehouse to avoid repeated deductions.

FAQ

**Q: Will the deduplication warehouse clear my previous screening number records? ** Answer: No. Records will be retained until the user voluntarily clears them or the storage limit is reached (see console instructions for details). You can view historical detection records at any time.

**Q: If the same number is detected on Telegram and WhatsApp respectively, will there be two deductions? ** Answer: Yes, because the platforms are different. Deduplication warehouses are judged based on the combination of “number + detection platform + detection type”. Cross-platforms and cross-types are not considered duplicates. Therefore, Telegram and WhatsApp are two independent detection dimensions, and each charges a fee.

**Q: The task prompts I submitted have 0 duplicates removed. What is the reason? ** Answer: Maybe the number has never been tested under this account before, or the detection type is different (for example, the previous detection was activation, but this time the detection is active). It is recommended to check historical task records for confirmation.

**Q: Is the number generated by the deduplication warehouse free of charge? ** Answer: The generated number itself is free (using the global number generation module). The deduplication mechanism will automatically take effect when the number is screened and deducted, and no additional deduplication service fee will be charged. You only pay for the actual number of tests.

**Q: Does it support cross-account deduplication? ** Answer: Currently only deduplication within the same account is supported. For multi-account management, please refer to subsequent feature updates, or contact customer service to learn about the enterprise version solution.
