Zalo activation data acquisition tutorial: complete steps for first screening and activation and then doing activity detection

In overseas marketing in Vietnam and Southeast Asia, Zalo is the core platform that cannot be avoided. Whether it is community operations, private message promotion, or cross-border e-commerce targeted customer acquisition, the first step is always to confirm whether the number you have is a valid Zalo user**. Many teams skip Zalo activation data verification and go directly to activity detection. As a result, a lot of budget is spent on invalid numbers. In today’s article, I will take you through the complete operation process: How to obtain Zalo activation data first, and then conduct Zalo activity detection on the activated numbers, so that you can spend the least money and get the most accurate target users.

What is Zalo activation data? Why is it a prerequisite for active detection?

Zalo activation data, simply put, is to mark whether a mobile phone number has been registered and opened a Zalo account. There are only two statuses for this detection result: “activated/valid” or “unactivated/invalid”. It does not include deeper information such as registration time, last login time, activity level, etc.

But it is this “open/valid” state that forms the basis for all subsequent operations. The reason is simple:

Activity detection for unactivated numbers = a waste of money. Activity detection will deduct fees at the same time, but the results of activity evaluation on an account that does not exist at all are meaningless.
Activation data is the first layer of the screening funnel. Only by first confirming that the number is a real Zalo user, is it necessary to further analyze whether it is active, gender, age and other attributes.

Therefore, any responsible Zalo customer acquisition process should take “obtaining Zalo activation data” as the first step.

What are the advantages of the detection sequence of activation first and then activation?

Many teams are accustomed to submitting a “big package test” at once and selecting all functions. This approach is not a big problem when the amount of data is small, but once the number database reaches tens of thousands or hundreds of thousands, the advantage of activating first and then becoming active becomes particularly obvious**.

Save screen number costs and avoid repeated deductions

Tip: Test Types and Billing

Zalo activation detection and active detection are two independent types with different unit prices. Total cost = number of activated detection strips × unit price + number of active detection strips × unit price. It is recommended to activate a small batch first to test and verify the quality of the numbers before deciding whether to be active. For specific unit prices, please see the real-time price on the console.

Let’s say you have 100,000 numbers and only 40% of them are active Zalo users. If activity detection is performed directly on all numbers, the activity detection fee will be deducted for 100,000 numbers. But if you do the activation test first:

Activation of detection: 100,000 activation fees will be deducted (the unit price is usually lower than active detection)
Active detection: Only 40,000 activated numbers will be deducted
Total cost: much lower than direct activity detection

The savings from this step-by-step operation become more significant when the amount of data is larger.

Improve data quality and make targeting more accurate

The activation data is used as the basis, and activity detection is only for real users. This means that there will never be “empty” or “unregistered” invalid data in your final export list. For scenarios such as adding Telegram followers and private message promotion, this step can directly increase the reach rate and response rate.

How to obtain Zalo activation data? Step-by-step guide

The following takes KK-DATA as an example to demonstrate the complete operation of obtaining Zalo activation data from scratch and completing activity detection.

Step 1: Prepare numbers to be screened (generate or import)

If you have a number, you can upload it directly. If you don’t have a number or want to add new data, you can also use the generation function.

Method 1: Using the Global Number Generation Module

After logging in to the console, enter the “Number Generation” module. Select the target country/region (such as Vietnam, Thailand, Indonesia and other popular Zalo areas), fill in the required number range or number, and generate it with one click. The generated functions are completely free and available on demand.

Method 2: Upload your own CSV/TXT file

If you already have a list of mobile phone numbers in your target market (in the format of one number per line, or CSV with number columns), you can upload it directly on the “Number Import” page.

Step 2: Submit Zalo activation detection task

Enter the “Number Filtering” page and click “Create Task”.
Select the platform as Zalo.
In the detection type, select “Activate/Active”.
Select the number file just generated or uploaded from “My Number Library”.
The system will display the estimated cost (calculated by the number of items). Submit the task after confirming it is correct.
After the task starts, wait for the processing to complete. Usually it ranges from a few minutes to tens of minutes, depending on the number of numbers.

Note: Balance and task limits

Make sure your account balance is sufficient. The maximum number of single tasks is about 1 million, and more than one task can be submitted in batches. You can check the estimated cost on the console before submitting.

Step 3: Export the activation number results

After the task is completed, find the task on the “Task History” page and click “Export”. It is recommended to choose CSV as the format because the fields are more complete. The exported file will contain:

number
Zalo activation status (True / False)
Timestamp etc.

In this way, you will get a pure Zalo activation data, and the numbers in it are all valid users who have registered with Zalo.

How to do activity detection on Zalo activation data?

After getting the activation number, the next step is to screen out users with real marketing value: Zalo active users.

Remove detected numbers to avoid double billing

If you use the same number library multiple times, it is recommended to use the data deduplication warehouse function. It can automatically remove duplicates between different tasks to avoid repeated detection of the same number (especially completed detection types such as activation status), thereby saving balances.

Of course, you can also do it manually: directly copy the list of subscribed numbers as input for a new task. Because active detection is a new task type, the deduction logic is different, and the activation fee will not be deducted repeatedly.

Submit Zalo activity detection task and export it

Create a new filtering task.
Select the Zalo platform again, but switch the detection type to “Active”.
In Optional Settings, select Active Window. Common options are 7 days, 14 days, 30 days, etc. Short-term marketing (such as limited-time activities) choose 7 days; long-term operations (such as community maintenance) choose 30 days.
Upload the activation number file exported in the previous step (or select it directly from the deduplication warehouse).
Submit the task, wait for completion, and export the results.

The second exported CSV will contain the “Zalo active” field (True / False). Only keep numbers whose activity is True, which are your precise target users.

Common misunderstanding: Can activation data replace active detection?

This is a very common misunderstanding. Some people think, “As long as you can add Zalo friends, it counts as active?” The actual situation is:

Zalo, like most social software, has a large number of “zombie accounts” - users do not log in for a long time after registering, and although the account exists, there is basically no active activity.
If you send marketing information to this type of number, you will not only get no reply, but may also be subject to system traffic restrictions or account bans due to low activity.

Therefore, activated data ≠ active data. Activating data is a necessary prerequisite, but it cannot be used as the basis for final screening. If you have requirements for reach rate and conversion rate, please be sure to do additional activity detection.

Examples of usage scenarios of Zalo activation data and active data

Different data states correspond to different marketing scenarios. Understanding these differences can help you put your data to good use.

Data type	Main purpose
Zalo activation data	Number library quality verification, updating obsolete number segments, basic A/B testing
Zalo activity data	Private message push, community invitation, precise advertising (remarketing)

Customer Acquisition in Vietnam Market: Screen Zalo active users to increase response rate

Vietnam is Zalo’s home base and its penetration rate is extremely high. If you are promoting to the Vietnamese market, first use the activation data to verify the validity of the number, and then conduct a 7-day activity test on the activation number, the response rate of the list obtained will usually be more than double.

Cross-border e-commerce targeting: further stratification based on gender field

KK-DATA also supports Zalo gender detection. Overlaying gender screening before and after active detection enables more fine-grained population targeting. For example: filtering users who are “Vietnam, active on Zalo, and male” for the promotion of a certain men’s shoe; or users who are “active on Zalo, female” for the beauty category. This way the data accuracy will be very ideal.

Summary and recommendation process

The entire operation pipeline is simple, but following this sequence will maximize your return on investment:

Number generation/import → Zalo activation detection → Export activation data → Zalo activity detection → Export active users → Targeted marketing

Each step is independent, but interconnected. Don’t skip steps, and don’t select all tests at once. Step by step operation, data is more controllable and budget is saved.

FAQ

Question: Does Zalo activation data include the registration time of the number?

Not included. Zalo activation detection only returns whether the number has been registered with Zalo (activated/valid status), and does not provide registration time, last login time and other fields. You need to supplement the time dimension data with activity detection.

Question: First screen for activation and then screen for activeness. Will this result in multiple deductions?

Yes, but it saves money. The two tests are billed independently, but the total cost is lower than doing an active test on all numbers directly. Because the activation fee is only deducted once for unactivated numbers, and the active detection only charges for verified activated numbers. See the real-time price on the console for details.

Question: Can Zalo activation + activity detection be completed at one time?

KK-DATA currently supports submission of tasks by platform and type, and does not currently support merging into a single step. It is recommended to operate in sequence, so that the data is more controllable and it is easier to check the number quality in the middle.

Question: How to choose the active window for Zalo active detection?

The console provides multiple windows (such as 7 days, 30 days, etc.), the actual options shall prevail. It is recommended to choose based on the promotion cycle: 7 days for short-term marketing and 30 days for long-term operations.

Question: Can the Zalo activated and active fields be seen at the same time in the export results?

Can. If you submit the task twice, the result of the second task (activity detection) will include the activity status of the number. You can use the number to associate the activation status of the first task, or you can use the number to match and merge the two exported data.
