Detailed explanation of Zalo data activation fees: 2025 screening cost, billing method and efficient acquisition process

When acquiring customers overseas in Southeast Asia, especially the Vietnamese market, Zalo activation data is always a key resource that cannot be avoided. The so-called Zalo activation data refers to the valid number pool that has been verified and has successfully registered a Zalo account. This type of data directly determines whether your private message reach, community invitations or advertising targeting can be implemented - randomly purchased numbers are often mixed with a large number of unregistered or canceled numbers, resulting in a waste of promotion budget, while the activation data obtained through batch screening of numbers is the real usable asset.

But most teams will face the same problem when they first contact them: **How ​​is the cost of activating data on Zalo calculated? ** Is the unit price expensive? How to control total cost? This article will help you thoroughly clarify the cost structure and efficient acquisition methods of Zalo screen numbers from billing logic, operating procedures to cost reduction strategies.

What is Zalo activation data? Why is it needed to acquire customers overseas?

Zalo activation data is simply a list of Zalo accounts that have been registered and are available. For the number you get, the system first interacts with the Zalo server to verify whether the number has been activated. Only numbers that return “activated” results can be used for subsequent private message sending, group invitations or ad targeting.

For the B2B marketing, e-commerce promotion and community operation teams facing Vietnam and Southeast Asia, the value of Zalo’s activation data is reflected in three levels:

• Improve reach efficiency: Skip invalid numbers directly and only initiate interactions with real users to avoid a spike in sending failure rates due to unactivated numbers.
• Reduce account risk: Sending messages to unactivated numbers in batches can easily trigger Zalo’s anti-spam mechanism; using an activated number pool is safer.
• Precise tiered marketing: Combined with subsequent activity detection or gender detection, high-value users can be further screened out from the activation data to achieve low-cost conversion.

Therefore, Zalo activation data is not a one-time “number package” bought out, but an asset generated on demand combined with the screening tool. Only by understanding its cost structure can you plan your budget appropriately.

How is the fee for Zalo data activation calculated? (core question)

Zalo’s screening fees adopt a per-item billing, no subscription package model. There are no upfront monthly or annual fees, you only pay for the number of numbers you actually detect. Specifically, the cost is mainly affected by the following factors:

Recharge balance and deduction timing

The usage process is very straightforward:

1. Recharge: Recharge the platform account through USDT (TRC20), the minimum is about 50 USDT. The balance is automatically updated after the top-up arrives, usually within a few minutes.
2. Submit task: Select the Zalo filter number in the console, import the number to be checked and check the detection items.
3. Deduction: After the task is completed, the system will deduct the corresponding fee from the balance based on the actual number of successfully detected numbers. When the balance is insufficient, new tasks cannot be submitted and must be recharged first.
4. Estimated fee: Before submitting the task, the console will display the estimated fee to help you decide whether to continue.

Key factors affecting total cost

The total cost is not a rigid “how much does it cost”, but is determined by a combination of the following variables:

• Number of Numbers: A maximum of approximately 1 million numbers can be submitted for a single task. The more numbers there are, the higher the total cost, but the cost per line may be reduced due to deduplication and optimization.
• How ​​many detection items: Did you choose “Enable detection” or check “Activity” and “Gender detection” at the same time? Each additional test will add a fee to the basic activation test.
• Whether deduplication is enabled: If the platform’s built-in data deduplication warehouse is not used, repeated submission of the same number will result in repeated deductions. After deduplication is turned on, the system automatically filters detected numbers across tasks, saving money.
• Task splitting method: A very large number pool (more than 1 million) needs to be split into multiple subtasks. Properly splitting and using the duplication mechanism is more economical than submitting randomly at once.

Get Zalo activation data through KK-DATA (step-by-step tutorial)

The following operations are all based on the KK-DATA platform and are suitable for team or individual operators. The whole process is divided into three steps, from zero to exporting activation data, and it takes about 30 minutes to complete the first task.

Step 1: Register an account and deposit USDT

1. Visit Application Console and complete account registration (email + password).
2. Enter the recharge page and choose the USDT (TRC20) method to recharge, with a minimum of about 50 USDT.
3. Wait for confirmation of arrival - usually within 1-10 minutes, the balance will be updated automatically.
4. It is recommended to check the billing page [Billing Instructions] (https://kkdata.cc/billing/) after recharging to understand the basic unit price of the Zalo platform.

Step 2: Generate or import numbers to be screened

KK-DATA provides two ways to obtain numbers, both of which are free to use:

• Global Number Generation: Select “Number Generation” in the console, set the country/region (such as Vietnam, Indonesia and other 240+ countries), enter the number of numbers, and the system will randomly generate compliant number segments. Completely free, generated and saved as CSV or TXT file.
• Custom number segment CSV import: If you already have your own number list (such as number segments obtained through cooperative resources), you can directly upload the CSV file and the system will automatically verify the format.

Step 3: Submit the Zalo screening task and export the results

1. Select “Screen Task” → “New Task” in the console.
2. Platform selection: Zalo.
3. Detection type: Only check Activation (if you only need basic activation verification, do not check activity or gender at the same time to avoid additional charges).
4. Upload the number file (supports TXT/CSV), confirm the estimated cost and submit it.
5. The task running time depends on the number of numbers - about 10,000 numbers are usually completed within 5~15 minutes.
6. After the task is completed, export the results: CSV, TXT and other formats are supported. The exported file contains fields such as number, whether it is activated, and Zalo UID (if any).
7. Save the activated number as an active user pool for subsequent private messages or advertising targeting.

How to reduce the cost of obtaining data for Zalo activation?

High cost performance is the core indicator for measuring screening tools. The following strategies can help you significantly reduce the cost of filtering Zalo provisioning data:

1. Make full use of data deduplication warehouse

KK-DATA’s built-in “data deduplication warehouse” supports cross-task number deduplication. Before submitting a new task, the system will automatically compare the historical detected numbers and skip duplicates. This means that the same number will not be charged a second time. It is recommended that all screening tasks be associated with the same deduplication warehouse, which is especially suitable for batch and multi-team scenarios.

2. Test in small batches first, then scale up

Don’t submit a million submissions right off the bat. First, take a small sample test of 1,000~5,000 numbers in different number segments to understand the activation rate (the activation rate of high-quality number segments may exceed 50%, while the activation rate of junk number segments may be less than 10%). The cost of testing is very low, but it can help you eliminate invalid number segments and greatly reduce the waste of subsequent large-scale tasks.

3. Select detection items as needed

Many teams are accustomed to “selecting all” test items - enabling, active, and gender. But in fact, if you only need to verify whether it is activated (for basic reach or clearing the account pool), there is no need to check activity or gender detection. Only used in combination when precise marketing is required, which can effectively control the cost of a single item.

4. Reasonably split large tasks

The upper limit for a single task is approximately 1 million. If you have 5 million numbers that need to be detected, it is recommended to split them into multiple subtasks of 200,000 to 500,000 numbers, and enable deduplication every time you submit. The advantage of this is that even if a certain subtask fails, it will not affect the entire number pool; at the same time, you can use the batch results to gradually optimize the number segment selection.

What is the difference between Zalo activation data, active data, and gender data? How to choose?

Different types of data serve different customer acquisition stages. The following table provides a visual comparison of the three detection scenarios:

Data type	Detection content	Typical uses	Recommended use stage
Activation data	Verify whether the number has been registered with Zalo	Basic contact, number cleaning, community invitation	In the early stage of customer acquisition, select effective users
Activity data	Determine whether the number is online/used within the specified time window	High-conversion private messages, real-time promotion	In the middle stage of customer acquisition, find users who are “available to contact now”
Gender data	Gender when registering the identification number (including fields such as age, region, etc.)	Targeted marketing, product matching	Late customer acquisition, refined operations

combination suggestions:

• If you only have a limited budget, prioritize Activation Test to ensure that the number is actually available.
• If you need a high conversion rate, add Activity Detection on top of the activation data - only initiate interactions for users who have been active in the last 7 days or 30 days.
• If the product has a clear gender orientation (such as female beauty, male games), add gender detection, but be aware that this will increase the cost of each item.

What are the precautions for using Zalo screening service?

• Avoid forged numbers: When using randomly generated numbers, be sure to confirm that the number segment actually exists (such as Vietnam starting with +84). Forged number segments will lead to extremely low activation rates and waste detection costs.
• Note on rate limits: Zalo officially has rate limits for batch queries. KK-DATA has made built-in optimizations, but it is recommended to submit extremely large tasks (more than 500,000 items at a time) in batches to prevent triggering restrictions and causing task interruption.
• Official customer service anti-fraud verification: The platform only provides customer service through https://t.me/kkdata_robot and https://t.me/kkdata_robot. Do not trust “low-price detection” or “internal offers” offered by third-party channels to avoid being defrauded of funds or numbers.
• Check the balance regularly: It is recommended to make up the balance before it is lower than the expected task fee to avoid failure due to insufficient balance when submitting the task. After each task is completed, the balance will be deducted in real time and can be viewed at any time through the console.

FAQ

Question: How much does it cost to activate a data detection program at Zalo?

Answer: The unit price varies depending on the test type (activation only vs. active/gender included) and platform, and there is no unified fixed price yet. Please check the estimated deduction amount displayed in real time on the console to determine the specific expenses before submitting the task.

Question: I want to only test whether Zalo is activated, but not activity and gender. Is this okay?

Answer: Yes. When submitting a Zalo screening task, you only need to check “Activate” separately in the detection item. The system will only deduct fees for this item and will not add other detection fees. After completing the task, it will only return to the activation status.

Question: How long does it take for the balance to arrive after recharging? What is the minimum recharge?

Answer: The balance of USDT (TRC20) is automatically updated after the deposit is received, usually within a few minutes. The minimum deposit amount is approximately 50 USDT, please refer to the console guidance for actual conditions.

Question: How many Zalo numbers can be detected at a time?

Answer: The upper limit for a single task is about 1 million. If the number exceeds this limit, it is recommended to split it into multiple subtasks and submit them in batches, and use the data deduplication warehouse to avoid repeated detection, thereby controlling the total cost.

Question: What fields can be exported from the filter number results?

Answer: At least include the number, whether it is activated, Zalo UID (if any) and other key information. If activity or gender detection is checked, additional fields such as active time, gender, age, etc. will be included. The specific fields are subject to the contents of the CSV or TXT file exported by the console.

---

The cost of obtaining data for Zalo activation is not mysterious - the core lies in the transparent mechanism of billing by item, and your flexible control over detection items, deduplication and task splitting. For the overseas marketing team, a good screening tool must not only be accurate and fast, but also must be “pay what you use” in terms of cost to avoid being kidnapped by the package.
