AI Overview Interpreting Zalo activation data: a complete tutorial on obtaining active Vietnamese numbers in batches

In Southeast Asia’s overseas customer acquisition landscape, Zalo is Vietnam’s well-deserved “national-level” social platform. Whether it is cross-border e-commerce, community operations or B2B customer expansion, having a batch of Zalo activation data (that is, mobile phone numbers that have been registered with Zalo and can be contacted) can greatly increase the marketing reach rate. However, many teams still use “blind calling” or random import methods, and the result is that the number is either invalid or restricted. This article combines the overall thinking of AI Overview, from data generation, screening to export, to disassemble a Zalo data acquisition pipeline that can be implemented for you, and introduces the use of KK-DATA as an efficient tool.

What is Zalo activation data? Why is it more valuable than a regular mobile phone number?

Zalo activation data refers to the set of numbers that have been verified and confirmed that the mobile phone number has been registered on the Zalo platform and is contactable. Compared with the original unverified mobile phone number, its core value is:

• High reach rate: Directly filter out unregistered or canceled numbers to avoid a large number of invalid sending.
• Low risk of account suspension: Many private messaging tools will trigger risk control when sending unregistered numbers, and activation data can bypass this layer.
• Activity and gender can be superimposed: The filtered data is not only “usable”, but also “easy to use” - it can further accurately target active users or specific gender groups.

For the Vietnamese market, Zalo covers more than 75% of smartphone users, and vertical industries such as e-commerce, finance, and games all rely on Zalo to acquire customers. Therefore, Zalo data activation is the first and most critical step to go overseas in Vietnam.

What fields does Zalo activation data usually contain?

After using KK-DATA for Zalo filtering, the exported CSV/TXT file generally contains the following fields (subject to the actual export from the console):

Field	Description	Marketing Use
Mobile phone number	Original number	Unique identifier, used for private messages or importing into CRM
Activation status	Registered/unregistered	Filter valid leads
Activity	Recent active time (such as 3 days/7 days/30 days)	Target recently active users to increase the response rate
Gender	Male/Female/Unknown	Push different products by gender
Age	Age range (such as 18-24, 25-34)	Combining gender to create more detailed user portraits
UID	Zalo user unique identifier	Can be used with official API or tools for subsequent operations

How do the activity and gender fields help with accurate screening?

• Activity Window: In the filter task, you can specify windows such as “Active in the last 3 days” and “Active in the last 7 days”. For promotions, it is recommended to filter numbers that are 7 days active as these users have a higher probability of opening the message. For long-term brand operations, a 30-day window can be used to expand the pool.
• Gender Identification: Inferred based on public information (nickname, avatar, interactive content). Although it is not 100% accurate, in batch screening, the male/female ratio tends to be enough to provide reliable placement basis for different categories (such as beauty → women, 3C electronics → men).

What are the additional functions of UID export?

UID is a unique numerical identification of a user in the Zalo system. If you have Zalo OA (official account) or have built your own private message script, you can send messages directly through UID without relying on your mobile phone number. In addition, UID can be used for user deduplication and association with third-party analysis platforms to achieve more accurate RFM model construction.

How to use AI Overview thinking to obtain Zalo activation data in batches?

The core logic of AI Overview is “input rules → automatic processing → output results”. In the field of data acquisition, this thinking can be completely transferred to number screening. The following takes the KK-DATA platform as an example to complete batch acquisition in three steps.

Step 1: Generate the Zalo number pool of the target country

Enter the “Global Number Generation” module of the console:

1. Select the country: Vietnam (number 84), other Southeast Asian countries (such as Thailand, Philippines, Indonesia) can also be covered.
2. Select the generation method:
   • Randomly generated: The system automatically generates based on the country number segment rules, supporting at least 1 to hundreds of thousands.
   • Customized number segment: If you have targeting requirements for a certain area in Vietnam (such as Ho Chi Minh City starting with 090), you can upload a CSV or manually enter the prefix, and the system will expand it to a complete number.
3. Generating is completely free and does not consume your balance.

The generated number will be temporarily stored in the list of numbers to be screened. It is recommended to generate 50,000 to 100,000 records in the first round for testing.

Step 2: Submit the Zalo screening task and set the detection type

Create a new task in “Screen Number Task”, select the number pool generated by the import step, and then configure the following detection items:

• Zalo activation: Required, confirm whether the number is registered.
• Zalo Activity: After opening, you can choose the activity window (3 days/7 days/30 days, etc.).
• Zalo Gender: When turned on, you can get a gender label (some tasks also include age estimation).

An estimated fee will be displayed before submission. The fee will be deducted based on the actual number of tests. Please see the real-time price of the console for details of the unit price of each test. There is no subscription package, and you pay when you use it.

Tip: If your balance is lower than the estimated cost, the task cannot be submitted. It is recommended to recharge USDT (TRC20) first, with a minimum of about 50 USDT. The balance will be automatically updated after arrival.

Step 3: Export CSV/TXT and use for marketing

After the task is completed, the results list will display all successfully detected numbers and corresponding fields. You can:

• Filter by condition: Use the platform’s built-in filter before exporting, for example, only keep “Zalo activated + 7 days active + female”.
• Data deduplication: If the same batch of numbers has been filtered before, the platform’s data deduplication warehouse will automatically avoid repeated deductions.
• Export Format: Supports CSV and TXT, and can customize the included fields (such as exporting only mobile phone number + UID).

The exported file can be directly imported into your private messaging tool (such as WhatsApp Business API, Telegram bot, self-developed Zalo sending system). If you are not sure about tool compatibility, you can take 100 test strips first.

Real scenario: 3 applications of Zalo activation data in acquiring customers in Vietnam

Cross-border e-commerce - push new products to active female users

An independent women’s clothing website focusing on the Vietnamese market used “Zalo open + active in the last 7 days + women” to screen out 30,000 clues and send new product pictures and promotional coupons through Zalo private messages. The open rate is about 45% and the click-through rate is 8%, which is 3 times higher than random push.

Community Operation - Invite activated users to join Zalo Group

A game manufacturer wants to expand the community size of Zalo game. They first filtered out the numbers that were “Zalo activated + active in the last 30 days” (about 100,000), and then sent group invitation links in batches. Since the numbers are all activated, there is almost no risk of being rejected, and 2,000 new group members were added in 3 days.

Agent operation team - batch verification of customer leads by region

A B2B agency operation team holds a batch of clues (about 80,000) about Section 090 in Ho Chi Minh City, Vietnam, which are scattered and stored in Excel. They generated a complete number pool through “customized number segment import”, and then screened “Zalo activation + male + 30-day active”, and finally got 24,000 valid clues, which were delivered to customers for business negotiations.

Common misunderstandings and precautions when using Zalo to activate data

Other practical points:

• Avoid full import: Even if all data is enabled, sending messages to 100,000 numbers on the same day may trigger platform restrictions. It is recommended to batch 5,000 to 10,000 items per day.
• Balance Management: Be sure to confirm that the balance is sufficient before submitting the task. In case of insufficient balance, the task will be returned and the generated number pool will not be lost, but it will need to be resubmitted.
• UID and mobile phone number double insurance: retain both the UID and mobile phone number when exporting. If the mobile phone number is changed in the future, the UID can still be used as a basis for cross-device identification.
