Zalo data activation tutorial for beginners: How to quickly verify the validity of Zalo accounts in batches

Newbies who are new to Zalo marketing are often troubled by several questions: Is the mobile phone number in their hand registered with Zalo? Which numbers are active? How to avoid wasting time and money when sending in bulk? The answer is hidden in Zalo activation data. This article explains in detail what Zalo activation data is and why you need it, and provides a complete operation process from manual verification to batch screening to help you get started quickly.

What is Zalo activation data?

Simply put, Zalo activation data refers to using technical means to determine whether a mobile phone number has registered a Zalo account. This is the most basic and important filtering field in Zalo marketing. After you get a batch of target numbers, the first step is to confirm whether they have activated Zalo. Only activated numbers can reach users through subsequent methods such as adding friends and sending group private messages.

In the screening platform (such as KK-DATA), Zalo detection usually includes the following fields:

• Activation detection: Verify whether the number has been registered with Zalo (return 1/0 or true/false).
• Activity Detection: Further determine whether the number has logged into Zalo within the specified time window (such as 7 days, 30 days).
• Gender Identification: Infer the user’s gender (male/female) based on public information or behavioral models. Some platforms also support fields such as age and region.

Newbies need to note: Active ≠ Active. A number may have registered with Zalo a few years ago but has never been online recently, so its value for short-term promotion is relatively low. Therefore, it is recommended that if the budget allows, check both the “activated” and “active” fields to obtain a more accurate reachable group of people.

Why should newbies pay attention to Zalo activation data?

Zalo is the dominant instant messaging app in Vietnam and Southeast Asia (especially Vietnam), covering more than 70 million users. For B2B/B2C scenarios such as cross-border e-commerce, overseas gaming, and independent website promotion, Zalo is an unavoidable customer acquisition channel.

However, blind mass messaging will bring about two fatal problems:

1. Waste of fees for invalid numbers: If you send invitations or advertisements to a bunch of numbers that are not registered with Zalo, not only will the other party not receive them, but it may also cause your number to be marked as spam by the platform.
2. Risk Control Risk: Adding a large number of non-existent numbers or frequently sending invalid accounts may easily lead to temporary account restrictions by Zalo.

Obtaining Zalo activation data in advance can act like a “filter” to retain only truly valid users who may be online. This can increase the conversion rate, reduce the probability of account closure, and make every budget spent wisely.

How to obtain Zalo activation data (beginner’s guide)

There are two common ways to obtain Zalo activation data: manual inspection and tool batch screening. Newbies can choose according to their own number size and budget.

Method 1: Manual inspection (suitable for very small amounts of testing)

If you only have a few dozen numbers, consider manual verification. Operation steps:

1. Install Zalo App on your phone.
2. Use the “Add Friend” function and enter your mobile phone number (requires international dialing code, such as +84 Vietnam).
3. If it displays “User found by mobile phone number”, it means that the number has been subscribed to Zalo; if it prompts “User not found” or “This number is not registered”, it means it has not been subscribed.

Limitations: It is very time-consuming, cannot be operated in batches, and manual search may trigger frequency limits. It is only suitable for novices to verify a few samples in the initial stage.

Method 2: Use the screening platform to obtain batches (recommended)

When the number of numbers exceeds dozens, manual verification is impractical. Reliable number screening platforms (such as KK-DATA) provide automated batch Zalo activation testing, support the submission of tens of thousands or even millions of numbers at a time, and return results within minutes to hours.

Taking KK-DATA as an example, it supports Zalo’s activation detection, activity detection, gender recognition and other fields, and charges are deducted on a per-item basis (no subscription package). The fees are transparent, and the estimated fee will be displayed before the task is submitted. For newbies, this is the fastest and most hassle-free way to get started.

Complete steps to use KK-DATA to obtain Zalo activation data

Let me take the KK-DATA console as an example to teach you how to complete a Zalo account screening task from scratch.

Step 1: Register/log in to the console

Visit https://app.kkdata.cc/ to complete registration and login. KK-DATA uses USDT (TRC20) anonymous recharge, the minimum is about 50 USDT, the balance is deducted according to the number, you pay as much as you use, no monthly fee is required.

Step 2: Prepare a list of mobile phone numbers to be tested

Organize the mobile phone numbers you want to detect into CSV or TXT files. Format requirements:

• One number per line, no extra spaces or special symbols.
• Must include complete international dialing code, for example, Vietnamese numbers are written as +84912345678 (+84 is the Vietnam area code, followed by 9 digits).
• If the number comes from other channels, it is recommended to remove duplicates first to avoid wasting balance through repeated detection.

Step 3: Create a screening task and select the Zalo platform

Navigate to the “Screen Task” page on the left side of the console and click “Create Task”.

1. Select platform: Check Zalo.
2. Select the detection type: at least check “Enable detection”. If you also want to know which numbers have been active recently or the user’s gender, you can check “Activity Detection” and “Gender Identification” at the same time (note that the unit prices of different types are different, see the real-time price of the console for details).
3. Upload the number file, or paste the number list directly.
4. The system will automatically calculate the estimated cost and submit it after confirmation.

Step 4: Submit the task and wait for the result notification

After submission, the task enters the queue. You can close the page and the task will run in the background. If Telegram has been bound (bind in the console settings), you will receive a notification after the task is completed. Usually Zalo’s activation test is a fast type, and the results may be available in a few minutes for thousands of numbers.

Step 5: Export and analyze data

After the task is completed, find the task in the “Completed Tasks” list and click “Export CSV” or “Export TXT”. The exported file contains the number you submitted and the corresponding test result fields. Common field meanings:

• zalo_open or is_open: 1=activated, 0=not activated.
• zalo_active or active_days: The number of active days or whether it is active within the specified window (such as 7d/30d).
• gender: male or female (only appears when gender detection is checked).

You can directly use Excel to open the CSV, filter out the zalo_open=1 numbers, and then combine it with other fields for the next step of marketing.

Suggestions for newbies to open Zalo data and other platforms (such as Telegram/WhatsApp)

The user profiles of different social platforms vary greatly. Newbies should choose the platform to prioritize based on the target market:

Platform	Main Markets	Applicable Recommended Scenarios
Zalo	Vietnam, Southeast Asia	Vietnam local promotion, e-commerce, games, finance, etc.
Telegram	Global (Encryption/Web3 Community)	Developers, Crypto, Blockchain Projects
WhatsApp	Global (except China)	Latin America, Southeast Asia, Europe and other mass markets
Line	Japan, Thailand, Taiwan	Japanese brands, two-dimensional, localized marketing

If you have plans for multiple lines at the same time, you can also upload the numbers in KK-DATA at once and create number screening tasks for Telegram, WhatsApp, Zalo and other platforms respectively, so that the data does not interfere with each other.

The 3 most common mistakes novices make and their solutions

Error 1: Wrong number format

Many novices directly import domestic 11-digit mobile phone numbers without international area codes. This will cause the screen number platform to be unrecognizable. Solution: Add international area codes (such as +84, +86, +1) when sorting, or use the platform’s built-in “global number generation” function to complete the area code first.

Mistake 2: Confusing activation and activation

I only did the activation test and thought that the numbers could be contacted directly. It turned out that a large number of numbers were not online for a long time and the contact efficiency was low. Solution: If the budget allows, also check “Activity Detection” and set a reasonable active window (such as within 7 days or within 30 days).

Mistake 3: Failure to remove duplicates leads to duplicate detection wasting balances

Numbers collected from multiple channels may be duplicated. If the task is submitted without deduplication, the same number will be detected multiple times, which will result in wasted money. Solution: Use Excel or KK-DATA’s “Data Deduplication Warehouse” function to remove duplication before submission. Subsequent tasks can also reference the warehouse to avoid repeated detection.

FAQ

Question: How long ago can Zalo detect registered accounts?

Answer: The activation test only verifies whether the number is currently registered for a Zalo account, and does not trace the registration time; the active test can specify the active time window (such as going online within 7 days/30 days), which is suitable for judging recent users.

Question: Is the “gender” in the test results accurate?

Answer: The gender field is inferred based on Zalo users’ public information or behavioral models, and is unofficial real-name authentication data. It has reference value for batch audience portraits and is not recommended as an absolute judgment.

Question: Can the balance be refunded after recharging?

Answer: Billing is by item. The estimated fee is displayed before the task is submitted. It will be deducted from the balance after the task is completed. Refunds are not supported for the consumed balance. It is recommended that users with zero experience first test with a small amount.

Question: Does Zalo number detection require the consent of the other party?

Answer: The detection behavior only verifies whether the number is registered with Zalo. It does not send messages or add friends, which falls under the category of data verification. It is recommended to use it compliantly and comply with the privacy regulations of the target region.

Q: Can the exported files be used for secondary marketing?

Answer: Yes. The exported CSV/TXT contains numbers and custom fields, which can be imported into CRM, mass messaging tools, or used for subsequent targeted promotions. However, be careful to abide by the Zalo platform rules and avoid violating risk control by adding friends in batches.
