How does the studio obtain Zalo activation data efficiently? A practical delivery guide

When traveling to Vietnam, you can’t avoid Zalo. This instant messaging platform with over 70 million monthly active users is the social tool with the highest local coverage in Vietnam, far exceeding other international applications. For studios undertaking the task of acquiring customers in the Vietnamese market, whether they can stably obtain accurate Zalo activation data directly determines the quality of delivery and profit margins. This article starts from the actual delivery scenario of the studio and breaks down the complete process from number preparation to data export, helping you avoid common pitfalls and achieve stable batch screening.

Why does the overseas studio need Zalo activation data?

Zalo’s position in customer acquisition in Vietnam

Among Vietnamese Internet users, Zalo’s penetration rate exceeds 90%, covering e-commerce, games, finance, tourism and other industries. Whether it is private community operations, customer return visits, or marketing event promotion, Zalo is a “must-have” option for reaching Vietnamese users. However, when studios undertake customer acquisition tasks in Vietnam, they often face a core problem: they have a large number of Vietnamese numbers on hand, but which are the Zalo accounts of that number? Which users are active? Who are the potential targets (e.g. men or specific age groups)? Without Zalo activation data, blindly sending messages is not only inefficient, but can also easily waste budget due to invalid numbers, and even trigger account bans on the platform.

What is Zalo activation data? What it means for studio delivery

Zalo activation data refers to testing the number to determine whether the number has registered a Zalo account (i.e. “activation”), and its further status (whether it is valid, active, etc.). For studios, this data is the basis for screening “reachable users”. For example, if a customer requires reaching 100,000 Vietnamese male users, if the original number database is used directly, only 30% may have opened Zalo; but after obtaining the activation data through the screen number, the actual number of reachable users will be clear, and the delivery budget can be accurately calculated.

What fields does Zalo activation data contain? How to interpret?

Taking the KK-DATA platform as an example, the fields exported from the Zalo number screening task usually include: number status (activated/unactivated), activity, gender, UID, etc. Only by understanding the meaning of these fields can you deliver efficiently.

The difference between open detection vs active detection

• Open Detection (Zalo Open): Determine whether the number has been registered with Zalo. This is the most basic filtering and is recommended for studios to use first.
• Activity Detection (Zalo Active): Based on activation, further determine whether the user has logged in recently (usually a time window can be specified). Active users are more suitable for reaching out via private messages, while users who are active but inactive may have abandoned their account or rarely use it.

Application scenarios of gender, UID and other fields in delivery

• Gender (including male targeting): If the customer requirement is “Vietnamese male users”, you can enable gender detection when filtering, and only keep the male field row after exporting. Note: Gender detection is based on user public information or platform data and is not 100% accurate, but it is sufficient to support batch targeting.
• UID: Zalo user’s unique identifier, which can be used for subsequent API access or reverse inspection.
• Age (supported by some platforms): For example, KK-DATA’s Telegram filter provides an age field, and Zalo filters may also contain similar data (subject to the console). Age can be used for vague targeting such as “people around 30 years old”, but do not interpret it as ID card-level accuracy.

Standard process for studios to obtain Zalo activation data in batches

The following process can be copied and used. The core tool is the KK-DATA platform (https://app.kkdata.cc/）。

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

• Number Generation (Free): Use KK-DATA’s “Global Number Generation” function, select Vietnam (country code +84), and generate the specified number or number segment. There is no charge for the generation itself, and the studio can obtain a large number of Vietnamese numbers for free.
• Number import: If you already have a number library provided by the customer (such as a CSV file), you can upload it directly. Supports CSV import of custom number segments.
• Deduplication: Whether generating or importing, it is recommended to go through the platform’s “data deduplication warehouse” first to avoid wasting balances through repeated detection.

Step 2: Submit the Zalo screening task and monitor the progress

1. Log in to the console and select “Zalo Screen Number”.
2. Upload or paste the deduplicated number list (the maximum number at a time is about 1 million, but it is recommended to submit in batches of 50,000-200,000 to facilitate management and retry).
3. Select the detection type: activated / activated + active / activated + active + gender (check as needed). The estimated cost will be displayed before the task is submitted. If the balance is insufficient, the task cannot be submitted.
4. After submission, you can check the progress in the task list. After the task is completed, you will be notified via Telegram (requires binding in advance).

Step 3: Export Zalo activation data and assign customers

Once the task is completed, select the export format (CSV/TXT) in the “Result Download” area. After exporting, it is recommended to perform further processing according to customer requirements:

• Filter by gender → Generate a separate “male user list”
• Filter by activity → Generate “Active users in the last 7 days”
• The exported field contains UID → can be provided to customers for API contact

The final output file plus the delivery payment summary table completes the delivery.

Potential pitfalls and pitfall avoidance techniques that may be encountered in batch screening

• Balance Control: The estimated cost displayed before submitting the task must be confirmed. It is recommended to reserve 10%–20% of the balance for each task to prevent recharge delays midway.
• Incomplete deduplication: If you import the same number multiple times, you will be charged repeatedly. KK-DATA’s deduplication warehouse can deduplicate across tasks. This function must be used before each submission.
• Activity window selection: The window for Zalo activity detection is generally “last 1 day / 3 days / 7 days”. If the window is too long, inactive users may also be included; if it is too short, the sample will be too small. It is recommended to flexibly adjust according to customer needs.
• Avoid submitting too many items at one time: Although 1 million items at a time is within the platform limit, the studio recommends splitting it into multiple small tasks (such as 100,000) to facilitate partial retry in case of failure and to facilitate grouping by customers.

What is the difference between Zalo activation data and WhatsApp/Telegram account number?

Many studios act as agents for the customer acquisition business of multiple platforms at the same time, and the focus of screening numbers on different platforms is obviously different. The following table can help with decision-making:

Platform	Core Market	Detection Field Characteristics	Common Delivery Scenarios
Zalo	Vietnam (dominated)	Open, active, gender, UID	Vietnam market private messages, community invitations
WhatsApp	Global (Latin America, Southeast Asia, India)	Activation, activity, gender, avatar	Cross-border e-commerce return visit, customer service
Telegram	Russian-speaking area, Middle East, Southeast Asia (part)	Open, active, gender, age, tgid	Cryptocurrency, community operation

Zalo’s advantage lies in its high local coverage in Vietnam and its relatively reliable gender detection. WhatsApp and Telegram are more suitable for global or language-specific audiences. The studio can flexibly combine platform screen numbers according to the customer’s place of origin.

Studio Delivery Quality Checklist

Before handing over data to customers, it is recommended to check the following items one by one:

• Data deduplication: Are there duplicate numbers in the exported file?
• Field Completeness: Are all promised fields (e.g. UID, gender, active status) included?
• Sampling Verification: Randomly select 10–20 “activated” numbers and manually search for verification on Zalo to confirm the accuracy.
• Format Compliance: The export format complies with customer requirements (CSV delimiters, encoding, etc.).
• Report Summary: Attached is a summary of the task (total number of numbers, activation rate, activity rate, gender distribution, etc.) to reflect professionalism.

FAQ

**Q: Is Zalo activation data accurate? How to verify? ** Answer: There is a certain error in platform detection (usually 95%+ accuracy). It is recommended to select 10–20 numbers marked as “activated” for manual verification, and then use them in batches after confirmation.

**Q: Does Zalo test support gender screening? Can you filter out male users? ** Answer: Supported. The Zalo filter provides a gender detection field that can filter male/female users. The specific fields are subject to the console export. Note that gender detection is based on public user information and is not 100% accurate, but is suitable for batch targeting.

**Q: What is the maximum number that can be submitted for Zalo activation testing at one time? ** Answer: The maximum number of single tasks is about 1 million, but it is recommended that the studio split it into small and medium-sized tasks of about 50,000-200,000 according to customer needs to facilitate management and monitoring.

**Q: Can I submit a task when the balance is insufficient? ** Answer: No. The estimated cost will be displayed before the task is submitted. It cannot be submitted if the balance is insufficient. You need to recharge USDT (TRC20) first, with a minimum of about 50 USDT.

**Q: Is there any difference in price between Zalo screen size and other platform screen sizes? ** Answer: The unit prices of different platforms (Zalo / WhatsApp / Telegram, etc.) and different detection types (activated only vs activated + active) are different. The specific price is based on the real-time price of the console. For details, please see [official website billing page] (https://kkdata.cc/billing/).
