Double the number screening efficiency: use the deduplication warehouse to avoid repeated detection, saving time and money
Batch verification of number validity, activity, and gender—this is a required course for overseas customer acquisition teams every day. But after you submitted several batches of Number Screening tasks for several days in a row, have you ever counted: How many numbers were tested last week? How much money is spent on repeat testing?
Data shows that when most teams screen numbers across tasks, the proportion of duplicate numbers is as high as 20%–40%. If you manually remove weights, it is time-consuming and labor-intensive and easy to miss. KK-DATA’s deduplication warehouse was created to solve this problem - the system automatically compares numbers across tasks and skips detected records, allowing you to only pay for new numbers and say goodbye to repeated deductions.
What is a deduplication warehouse? Why does number screening need to remove duplicates?
Duplication Warehouse is the number history detection record library built into the KK-DATA platform. When you submit any number screening task, the system will automatically compare the number to be inspected with all completed tasks of the same type in the warehouse, identify the numbers that have been inspected, and automatically skip these numbers in the task - no deductions will be incurred.
Why is it needed? Imagine this scenario:
- You generated 500,000 U.S. number segments from global numbers, submitted the Telegram activation test first, and spent about 500,000 balances.
- A few days later, you decide to do another Telegram activity check on these 500,000 numbers. If submitted directly, the system will check all 500,000 numbers again, and those numbers that have passed the test will be repeatedly deducted.
- The deduplication warehouse will recognize that the previous “activation detection” has been completed, and the activity detection belongs to a different detection type, so it will not be blocked. But if the task you submit for the second time is exactly the same detection type as the first time, the deduplication warehouse will be automatically skipped.
In other words, the deduplication warehouse is the core of cost control for number screening: it remembers which numbers have been verified for you, avoiding repeated expenditures for the same type of detection.
The key to saving money
The deduplication warehouse does not distinguish task batches, and only determines whether they are duplicated by “platform + detection type + number”. For the same number under the same platform and the same detection type, the fee will be deducted only once.
How does deduplication warehouse work? Core mechanism for cross-task number filtering
The deduplication warehouse does not require any configuration and runs automatically in the background. When all screening tasks are submitted, the system will:
- Read the number list in the task;
- Query the historical records of this platform and this detection type in the warehouse;
- Mark the detected number as “duplicate”;
- Only initiate actual quality inspection for untested numbers;
- After the task is completed, the results will be written to the warehouse for comparison in subsequent tasks.
The entire process is completed in milliseconds, and you only need to see the prompt “N duplicates are expected to be removed” on the console.
Determination logic for cross-task deduplication
The determination of deduplication warehouse is based on three dimensions:
- Number: Unique identifier in international format (such as
+8613800138000); - Platform: Telegram, WhatsApp, Line, Zalo and other different platforms are recorded separately;
- Detection Type: Under the same platform,
tg开通,tg活跃, andtg性别are considered different detection types.
Example: The number +1234567890 was tested for Telegram activation in the previous task, and the warehouse is recorded as “Telegram 开通✅”. The next time you submit a task that also does “Telegram 开通”, this number will be skipped. But if you submit “WhatsApp 开通”, it won’t be skipped - because the platforms are different.
Does deduplication affect the timeliness of test results?
Number status changes dynamically. For example, a Telegram user who is active this month may be inactive next month. The deduplication warehouse allows users to specify the detection window: you can check “Force retest” or set “Retest if the last detection is more than X days” when submitting the task. This can not only save costs by using deduplication, but also ensure that key numbers have the latest status.
Best practices for using deduplication warehouses for number screening
Reasonable use of deduplication warehouse is essentially to find a balance between “cost minimization” and “data freshness”. The following practical methods can help you maximize your profits.
Deduplication strategy when combining multiple platforms to screen numbers
When you want to verify the same number on multiple platforms (such as Telegram, WhatsApp, Line) at the same time, do not merge them into the same task. The correct approach is:
- First generate or prepare a list of target numbers (generated for free);
- Submit the task of the first platform (such as Telegram activation);
- Submit tasks for the second platform (such as WhatsApp activation);
- Use the deduplication warehouse to record independently without confusion.
There is no overlap between different platforms, so each task only deducts the detection fee of the number on that platform. If the number has been detected on Telegram and then tested on WhatsApp, the warehouse will not misjudge it as a duplicate.
Partition packaging tasks use deduplication warehouse
When the number exceeds the upper limit of a single task (about 1 million), it needs to be split into multiple subtasks. For example, 3 million numbers are divided into three 1 million tasks and submitted in sequence. The deduplication warehouse will automatically compare all previously completed similar tasks when each subtask is submitted to ensure that the second and third subtasks will not repeatedly detect previously measured numbers.
best practices
It is recommended to perform the global number generation and screening tasks step by step: first generate the number (free), then upload or directly select the generated result to submit the screening number. The deduplication warehouse will automatically handle the duplication between the generation and previous tasks.
How much cost can deduplication warehouse save you? Actual scenario analysis
Suppose you are a cross-border e-commerce team and you need to screen three batches of numbers every month:
- The first batch: Generate 200,000 US number segments from global numbers for Telegram activation testing.
- The second batch: One week later, about 80,000 numbers that have been successfully activated will be tested for Telegram activity.
- The third batch: After another week, gender detection will be performed on 30,000 active users.
It seems that the number of numbers in each batch is decreasing, but in actual operation, you are likely to purchase several number packages from third-party channels, and there is a lot of duplication between these packages (for example, the same number segment has been sold by different suppliers). If you don’t remove duplicates, 30% of the numbers in the third batch of tasks may have been detected in the first two batches - and as a result, you paid twice or even three times for these duplicate numbers.
After using the deduplication warehouse, the system will automatically skip the measured numbers even if you import numbers from different sources. A conservative estimate is that deduplication warehouses can eliminate 20%–40% of duplicate charges, depending on the degree of overlap in number sources. For a team that screens millions of entries every month, this savings is significant.
How to enable deduplication warehouse? KK-DATA operation steps
The deduplication warehouse is a built-in function of the KK-DATA system, and there is no need to manually enable or install any plug-ins. You only need to submit the screening task normally to automatically benefit.
Deduplication prompts when submitting tasks
Before submitting the task, the confirmation page of the console will display a line of estimated information, such as:
There are a total of 50,000 numbers in this task, 12,300 of which have been detected (Telegram is activated), and it is expected that 12,300 numbers can be removed.
You can use this to determine how much balance will actually be deducted this time. If the estimate is incorrect (for example, the number status has changed), you can also cancel the task, adjust the parameters, and retry.
View deduplication report
After the task is completed, there will be a field “Number of skipped repetitions” on the task details page or in the export results. For example:
| Total number of numbers | Actual number of detections | Number of skipped duplicates | Deduction balance |
|---|---|---|---|
| 50,000 | 37,700 | 12,300 | 37,700 times |
This allows you to accurately calculate the cost of each task and evaluate the savings brought by deduplicated warehouses.
Deduplication warehouse vs manual deduplication: Why is automation more reliable?
Many teams are accustomed to using Excel or self-written scripts to manually remove duplicates. In contrast, the advantages of automated deduplication warehouses are very obvious:
| Compare dimensions | Manual deduplication (Excel) | Self-built script to deduplicate | Deduplication warehouse (automatic) |
|---|---|---|---|
| Real-time | Import and export every time | Database maintenance required | Real-time online matching |
| Cross-task tracking | Difficult to cross workbooks | Global tables need to be designed | Automatically cross all tasks |
| False positive rate | High (different formats) | Rely on regularity | Based on standard number hashing |
| Maintenance cost | Low but long time | Development/operation and maintenance investment | Zero maintenance |
| Applicable scale | Ten thousand level | Million level | Million level + |
The greatest value of the automated deduplication warehouse is that it is no sense: you do not need to remember which numbers have been measured before, the system automatically filters them for you. For a team that is sifting through numbers every day, this efficiency improvement is sustainable.
FAQ
**Q: Does the deduplication warehouse distinguish between different detection types (such as tg activated vs tg active)? **
Answer: Distinguish. Deduplication warehouses are recorded independently according to “Platform + Detection Type”. For the same number, under the Telegram platform, activation detection and activity detection are considered different tasks and will not skip each other. In this way, you can activate it first and then activate it, and the fees will be deducted normally for both tests.
**Q: If I want to recheck the same batch of numbers (for example, one week apart), will the deduplication warehouse prevent it? **
Answer: It will not be forcibly blocked. When submitting the task, you can check “Force retest” or set “Retest if the last test is more than X days ago”. The deduplication warehouse will respect your choice and allow you to pay to check the number that has been checked again to obtain the latest status.
**Q: What number formats does the deduplication warehouse support? **
Answer: Supports international common format (with country code, such as +86xxxxxxxxx). The system automatically normalizes to ensure that identical numbers from different sources are matched correctly. It is recommended to add +86 for Chinese numbers and +1 for American numbers.
**Q: Will the balance after deduplication be automatically returned? **
Answer: Deduplication is not “refund after deduction”, but exclude duplicate numbers before detection, so fees have never been deducted. The duplicate portion has been automatically deducted from the balance of task expenditures, and no additional operations are required.
**Q: Is the deduplication warehouse applicable to the global number generation module? **
Answer: Applicable. Global number generation is a free function, and the generated number list can be directly referenced by number screening tasks. The deduplication warehouse will compare the task with existing records in the warehouse to prevent you from repeatedly checking generated numbers that have been verified before.
The deduplication warehouse is the most easily overlooked but most direct tool to save money when overseas teams conduct number screening. It automatically helps you remember which numbers have been verified, allowing you to spend every penny on adding new numbers instead of paying repeatedly.
