Zalo activation data vs Telegram activation: How to choose the right screening direction for cross-border customer acquisition?

In the overseas customer acquisition scenario, batch verification of whether the number is registered on the target platform (i.e. enabling detection) is the first step in data cleaning. Zalo activation data and Telegram activation detection each serve different regions and user groups: the former focuses on Vietnam and Southeast Asia, and the latter covers encrypted communication users around the world. Many teams will purchase or build both detection capabilities at the same time, but there are still cognitive blind spots on how to reasonably allocate budgets and improve conversion rates according to the target market. This article will make a system comparison from the dimensions of coverage area, activity identification, available fields, and billing modes, and provide a combination strategy based on the multi-platform screening function of KK-DATA.

What is Zalo activation data? Why is it important for customer acquisition in Vietnam/SEA?

Zalo activation data refers to the status of confirming through number detection that the number has been registered on the Zalo platform and can receive messages. Zalo has more than 70 million monthly active users in Vietnam and a penetration rate of nearly 90%. It is a mainstream social tool in Vietnam. For e-commerce, gaming, finance, and agent operation teams facing the Vietnamese market, Zalo is the preferred channel for localized communication.

The number screening tool can submit numbers in batches and return whether each number is Zalo-enabled, as well as optional fields such as gender, uid, etc. Using this data, the team can filter out real Zalo users for use in private message promotion, community recruitment, event notifications and other scenarios. Zalo messages typically have higher open and response rates than generic SMS or voice marketing at a manageable cost.

What markets and scenarios is Telegram activation detection suitable for?

Telegram activation test (also called TG registration test) verifies whether the number has been registered in Telegram. Telegram occupies an important position in the global encrypted communication market, especially in Russia, Ukraine, Iran, Indonesia, Brazil, the United States and other regions, with a large number of active users. Common application scenarios include:

• Airdrop and Hair Raising Activities: It is necessary to confirm that the TG account corresponding to the wallet address actually exists.
• Community Operation: Filter out invalid numbers before inviting users to join channels/groups in batches.
• Private message promotion: Send promotional messages to active TG users.
• Cross-platform customer acquisition: Use Telegram as a supplementary channel for global reach.

Unlike Zalo, Telegram’s activation detection is usually combined with activity detection (such as login behavior in the last 7 days/30 days), because there are a large number of “register and discard” numbers among TG users, and activation data alone cannot guarantee the reach effect.

Zalo activation vs Telegram activation: comparison of six key dimensions

Comparison dimensions	Zalo activation data	Telegram activation detection
Main coverage areas	Vietnam, Indonesia and other Southeast Asian countries	Global (CIS, Middle East, South America, Southeast Asia, etc.)
User age/gender field	Gender (male/female) can be identified, and some numbers have age groups	Gender + age range (such as people around 30 years old), for accuracy, please refer to the console instructions
Activity Identification	Some numbers support active status (need to be paired with activity detection)	Support specified time window activity detection (7 days/30 days, etc.)
Export fields	Number, uid, gender, region, etc. (subject to the console)	Number, tgid, active time, gender, age, avatar link, etc.
Single task volume	Up to about 1 million items	Up to about 1 million items
Fees Mode	Deduction by item, please see the real-time price on the console for details	Deduction by item, the unit price is different on different platforms

Differences between regional coverage and user portraits

• Zalo: almost monopolizes the social scene in Vietnam, and user portraits tend to be localized (young office workers, housewives, etc.). There is also partial coverage in Indonesia, but it is far less than that in Vietnam. A team suitable for localized marketing in Vietnam.
• Telegram: Users are more widely distributed, with CIS countries (Russian-speaking areas) accounting for a large proportion, followed by the Middle East, Southeast Asia, and South America. Telegram users are more receptive to topics such as encryption, technology, and finance. If the target customers are overseas Chinese, investors or blockchain practitioners, TG is the first choice.

What fields can be obtained by filter number?

Zalo filters typically return:

• number
• uid (Zalo internal user ID)
• Gender
• Mark provinces or cities in some areas

Telegram filter number can return:

• number
• tgid (Telegram unique identifier)
• Active time (last login time)
• Gender + age (e.g. “Male, around 30 years old”)
• Avatar information (supported by some tasks)

Note: Age data comes from platform inference and is not an ID card-level accuracy and should not be used as the sole basis for decision-making.

How to use Zalo activation data and Telegram activation to create a combined account?

Best practice is to build a Build → Filter → Export pipeline:

1. Bulk number generation: Use the global number generation module to generate a batch of number segments according to the target country (such as Vietnam), or import your own number segments through CSV.
2. Submit two detection tasks at the same time: Submit the same batch of numbers to Zalo activation detection and Telegram activity detection respectively (it is recommended to check the active window to reduce invalid data).
3. Export cross-hit users: Export numbers that meet the conditions of both platforms on the console, and reach these users first.

This combination can maximize number utilization - if a number can be reached on two platforms at the same time, it shows that users are highly receptive to social platforms, which facilitates multi-channel marketing. Of course, you can also screen only one platform based on your budget, but the value of cross-data is higher.

Zalo has enabled screen account and Telegram activity detection, which one has a higher conversion rate?

The conversion rate depends on the target user’s language habits and country.

• Zalo activation data: Suitable for localized product promotion in Vietnam, especially suitable for consumer categories that do not require strong technical beliefs (e-commerce, takeout, local services). Zalo messages typically have higher open rates than Telegram because Zalo users are used to receiving branded messages.
• Telegram Activity Detection: Suitable for virtual currencies, software development tools, online courses and other products for technology/investment groups. TG active users are generally more likely to click on a link, participate in a test, or register. If targeted globally, the conversion rate of TG active detection is 2-5 times higher than that of simple activation detection (depending on the industry).

It is recommended to make a choice based on the language preference of the target customers: if Vietnamese is the main language, Zalo will be preferred, and if English/Russian is the main language, Telegram will be preferred.

Common misunderstandings and precautions when using screening tools

Why is it not enough to just test the activation?

Many teams only look at the activation rate, and as a result, a large number of messages are ignored or the accounts are deactivated. Taking Telegram as an example, many “zombie accounts” that are never used after registration can still be detected as activated, but there will be no reply after sending a message. Active detection can filter out this part of the noise and improve subsequent operational efficiency.

How to avoid repeated deductions?

The number screening platform usually deducts fees based on the “actual number of detected items after deduplication”. However, if you upload the same number in different tasks and the platform does not perform cross-task deduplication, repeated deductions will occur. KK-DATA has a built-in data deduplication warehouse that automatically recognizes and skips detected numbers to save balance. It is recommended to use the deduplication function before each upload, or to deduplicate locally in advance.

Also, pay attention to the area code matching. The correct country code (such as Vietnam +84, Indonesia +62) must be included when uploading the number, otherwise it may be recognized as an invalid format and waste detection opportunities.

Summary and next steps

Zalo activation data and Telegram activation detection are two complementary screening capabilities for overseas customer acquisition. The former is deeply involved in local markets in Vietnam and Southeast Asia, while the latter covers global encryption users. The best strategy is to use a combination according to the target market: first obtain the target number segment through the number generation module, and then submit Zalo and Telegram detection tasks at the same time, using cross-data to improve reach efficiency.

If you are looking for a platform that supports multi-platform screening, billing by item, and no subscription, you can learn about KK-DATA (official website). It provides functions such as global number generation, cross-platform number screening, and data deduplication warehouse. All tasks are deducted based on the number of test results. For details, see [Console Real-time Price] (https://app.kkdata.cc/).

FAQ

**Q: Can the Zalo activation data screen out male users? ** Answer: Yes. KK-DATA provides Zalo gender recognition fields, which support targeted filtering such as “male” and “female”, and are suitable for male-oriented products or operational activities.

**Q: What is the difference between Telegram activation detection and active detection? ** Answer: The activation test only verifies whether the number is registered with TG; the active test can set a time window (such as 7 days/30 days), and only outputs users who have logged in during this period, so that the filtering results are more accurate.

**Q: I have a batch of domestic numbers, can I screen Zalo and Telegram at the same time? ** Answer: Yes. The platform supports uploading any country/region number, and the system automatically detects the status of each platform. Domestic numbers have a small number of online numbers on Zalo. It is recommended to give priority to testing other platforms such as Telegram and WhatsApp.

**Q: What are the export fields for Zalo activation data? ** Answer: It usually includes number, uid, gender, region (some support), etc. The specific results are subject to the console task results. TG can also export fields such as tgid, active time, age, etc.

**Q: Can the screening task be canceled after submission? How to refund the balance? ** Answer: Once a task is submitted and entered into the queue, it will start consuming resources and cancellation is not supported. The balance will be deducted based on the actual number of items after the task is completed, and the unused balance can be retained for a long time for subsequent tasks.
