Zalo activation data batch detection tutorial: use KK-DDATA to efficiently filter valid numbers

Zalo is the most mainstream instant messaging application in Vietnam and even Southeast Asia, covering more than 70 million active users. For overseas cross-border e-commerce, independent website promotion and community operations, Zalo is a customer acquisition channel that cannot be ignored. But blindly sending messages to numbers that are not registered with Zalo not only wastes resources, but may also be labeled as harassment. At this time, Zalo activation data - that is, whether the number has been registered with Zalo and its activity, gender and other information - has become the “first filter” for precision marketing. This tutorial will teach you step by step how to use the KK-DDATA platform to detect Zalo numbers in batches, lock in real users at low cost, and improve the conversion rate.

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

Zalo activation data, simply put, it means whether a mobile phone number has been registered on the Zalo platform. The status returned after detection is usually divided into “activated” (registered) and “unactivated” (unregistered or unable to be verified). But this is just the basics. In actual customer acquisition scenarios, what is more critical are the activity and gender fields:

• Activity: Determine whether the number has logged in or used Zalo recently. Target messages to active users for higher open and response rates.
• Gender: Some numbers support gender identification (male/female) and can be used for targeted marketing, such as promoting women to beauty and fashion products, and men to promoting games and finance.

**Why is it important? ** Suppose you have a list of 100,000 Vietnamese local numbers and import them directly into Zalo to attract groups or send private messages. At least 30%–50% of the numbers may have never been registered with Zalo, which is a waste of traffic and costs. By first detecting Zalo activation data, you only need to initiate actions on “activated + active” numbers, and the conversion rate can be increased by 2–3 times. At the same time, gender recognition is superimposed to further narrow the crowd and avoid harassing non-target users.

How does KK-DDATA detect Zalo activation data?

KK-DDATA is a professional multi-platform screening system that supports batch detection of mainstream social platforms such as Telegram, WhatsApp, Line, and Zalo. When it comes to Zalo detection, it offers three core dimensions:

• Zalo activation detection: Determine whether the number is registered with Zalo (basic state)
• Zalo Activity: Distinguish between “recently active” and “silent users” (the active window can be customized, see the console for details)
• Zalo Gender Identification: Can filter male, female or unknown gender (including additional information such as age, but the console export fields shall prevail)

In addition, after the detection is completed, the uid (Zalo internal user ID) can be exported, making it easier for you to connect with other tools for secondary verification or deduplication.

All detections are based on Zalo’s official public interface. The platform only performs status requests and returns, does not store user chat content, and does not involve privacy violations. Data use is limited to compliance marketing.

Zalo activation detection: Determine whether the number is registered with Zalo

The operation is very simple: log in to KK-DDATA Console, enter the “Screen Number Task” module, and select “Zalo Activation Detection”. You can submit your number via:

• CSV/TXT file upload: supports one number per line, up to about 1 million at a time.
• Manual Paste: Enter directly when working in small batches.
• Global Number Generation: If you don’t have a ready-made number on hand, you can first use the platform’s “Number Generation” function (free) to generate a random number segment or a custom number segment for the target country.

After submission, the system will automatically send a verification request to the Zalo server and return the registration status of each number. Typically tens of thousands of tests are completed in 10–30 minutes (depending on network and queuing). After the task is completed, you will receive a notification in the console, and you can also set a Telegram push reminder.

Note:

• Make sure the number is in international format (e.g. +84xxxxxxxxx).
• “Activated” in the test results only means that the number has been registered with Zalo, and does not guarantee that it is still in use.

Zalo activity and gender fields: further precise targeting

“Opening” alone is not enough. Many Zalo accounts may have been inactive for a long time due to account changes or abandonment. KK-DDATA’s Zalo Activity Detection can tell you whether the number has logged in recently (the active window can refer to the console settings, such as within 7 days, within 30 days, etc.). It is recommended to give priority to users in the “active” status to reach them, as the probability of replying is significantly higher than that of silent users.

Gender identification is connected to the gender field in Zalo’s public information (some users have disclosed their gender). After detection, the console returns “male”, “female”, or null. You can directly filter out men/women and push differentiated content.

Practical scenario examples:

• A beauty brand in Vietnam wants to promote new products: first screen Zalo activated + active female users (export uid), and then send coupons through private messages or Zalo OA.
• Game promotion: Screen open + active male users and issue test qualifications.

Complete steps for batch detection of Zalo activation data

Below we take a typical screening task as an example to demonstrate the complete process from generating numbers to exporting results.

Step one: Log in to the console and recharge

1. Visit https://app.kkdata.cc/ to register/log in.
2. Enter the “Balance” module and use USDT (TRC20) to recharge (minimum about 50 USDT). The balance is billed on a per-item basis, with no package restrictions. You can recharge as much as you use.
3. After the recharge arrives, it is recommended to conduct a small test first to familiarize yourself with the process.

Step 2: Prepare number source (generate or upload)

• Ready-made numbers are available: Directly upload CSV/TXT, the format is one number per line, it is recommended to include the international area code.
• No Number: Use the “Number Generation” function. Select the country “Vietnam” (or the target country), set the number segment (such as starting with 84), and click Generate to get a large number of random numbers. Generating is completely free and does not consume your balance.

Step 3: Create Zalo screening task

1. Click “New Task” in the console → select “Zalo Screener”.
2. Detection options: Check “Zalo activation detection” (required), and then check “Activity detection”, “Gender detection”, etc. as needed. Different options correspond to different charges, and the console will display the estimated charges in real time.
3. Select Number: Upload your number file, or load it from the number warehouse (if it has been generated before).
4. Submit the task. Make sure the balance is sufficient before submitting, otherwise the submission will not be possible.

Step 4: Wait for the task to be completed

After submission, the task enters the queue. You can view the progress (in percent) in the task list. Larger tasks may take several hours, but generally a single batch of less than 100,000 items can be completed within an hour. Upon completion, you will be notified via Telegram (Bot needs to be bound in advance).

Step 5: Export results

Once the task is completed, click the “Export” button and select CSV or TXT format. The export file contains the fields of your choice, for example:

Mobile number	Zalo status	Activity	Gender	uid
+849xxxxx	Open	Active	male	123456

You can use Excel to filter out the list of “open+active+male” and then import it into Zalo or other tools for further marketing.

Best practices and considerations

• Small batch testing first: It is recommended to submit 100-500 numbers to the channel for the first time, and then operate in large batches after confirming that the detection effect and billing are correct.
• Combined with deduplication warehouse: KK-DDATA provides a “data deduplication warehouse” function, which can deduplicate across tasks and avoid wasting balance by repeatedly detecting the same number.
• Activity window selection: Select “Active within 7 days” or “Active within 30 days” according to your marketing timeliness. If it is a brand exposure that does not require high timeliness, a 30-day window is enough; if it is a limited-time event, choose to be active within 7 days.
• Gender recognition accuracy: The gender field comes from the user’s public information and is not 100% valuable. Numbers with missing gender can be ignored or treated as neutral.
• Comply with platform rules: After exporting data and using it on Zalo, please be sure to comply with Zalo’s usage policy and local laws and regulations to avoid excessive harassment of users that may lead to account suspension.

FAQ

**Q: How long does it take for KK-DDATA to detect Zalo activation data? ** A: The detection time depends on the number of numbers and the queue situation. Usually about 5–15 minutes for 10,000 numbers; about 30–60 minutes for 100,000 numbers. When the task is completed, you will be notified via Telegram or the console.

**Q: How accurate is Zalo gender detection? Why do some numbers have no gender information? ** Answer: The gender field comes from the user’s public information, and the accuracy rate is high (about 80%–90% has the gender filled in). If the user is not public or has not filled in, a null value will be returned. It is recommended to make a comprehensive judgment in conjunction with other fields.

**Q: If the test result shows “Not activated”, does it mean that this number must not be registered with Zalo? ** Answer: Not absolutely. “Not activated” means that the number was not registered with Zalo at the time of current detection, but the user may have registered it later, or the number may have been recycled. Normally in a marketing scenario, you should prioritize numbers with “open” status.

**Q: Can I just do the activation test without selecting activity level and gender? ** Answer: Yes. Activation detection is a basic option and can be used alone to filter out most invalid numbers. Activity and gender are value-added options, you can check them as needed, and the fees are different.

**Q: Can the balance be refunded after recharging? ** Answer: The balance after recharging can only be used for number screening tasks, and withdrawal is not supported. It is recommended to recharge with a small amount first for testing, and then decide the subsequent amount based on usage.
