Southeast Asia Huoke Technology Inn: How to use the screening service to efficiently get through Zalo + Line + Telegram

Vietnam’s Zalo penetration rate exceeds 90%, Thailand’s Line ranks among the top three in terms of user count, and Telegram has become a public front for cross-regional overseas communities with its channels, groups and robot ecosystem. But the embarrassment of many teams is that they hold a batch of numbers, and after putting in a large number of invalid numbers, zombie numbers, or even empty numbers, the conversion rate is dismal. The root cause is not “not enough numbers”, but not filtered by the number screening service - not knowing which numbers are actually available, which are active, and which are the target gender/age. This article will dismantle a Southeast Asian customer acquisition technology stack and teach you how to use screening service to connect the three platforms of Zalo, Line, and Telegram into an efficient customer acquisition pipeline.

Why does Southeast Asia need to combine Zalo + Line + Telegram to acquire customers?

Southeast Asia is not a “single market.” User habits are highly fragmented:

Countries/Regions	Dominant Social Communication Platforms	Features
Vietnam	Zalo	Ultra-high penetration rate, users are accustomed to using Zalo for shopping, customer service, and group chats
Thailand	Line	Line covers more than 95% of smartphone users and is the core of business social networking
Malaysia	WhatsApp + Telegram	WhatsApp family communication, Telegram communities/channels are popular
Philippines	Facebook Messenger	But Telegram is growing rapidly in the gaming/cryptocurrency community
Indonesia	WhatsApp	Telegram’s share of e-commerce/promotion scenarios continues to rise

– Single platform cannot cover all of Southeast Asia.
– Screening service can help you verify the number status of multiple platforms at one time to avoid repeated purchases and invalid contacts.

For example: a financial product targeting the Vietnamese market first uses Zalo to screen out active users, then uses Line to screen the Thai radiation population, and finally uses Telegram to create a cold-start community. Only by taking turns on the three platforms can the reach efficiency be maximized.

What is the screening service? How to help acquire customers in Southeast Asia?

Screening service is a technical solution that detects number registration status, active time, and public information fields (gender, age, avatar, etc.) through platform protocols. It does not actively send messages or harass users. It only returns structured data: Is this number active on Telegram? Active in the last 7 days? Are public profiles shown as male or female? Approximately how old are you?

In the customer acquisition scenario in Southeast Asia, the core value of the number screening service is:

1. Filter empty/unactivated numbers – Avoid wasting costs by sending promotions to invalid numbers.
2. Lock active users – Only select numbers with activity in the last 30 days or 7 days to increase reach conversion.
3. Targeted gender/age – For example, mobile game promotion only targets males aged 18-35, while cross-border e-commerce promotion of maternal and infant products targets females.
4. Export platform uid – to facilitate subsequent group gathering, private messages or data matching.

The three pillars of Southeast Asia’s Huoke Technology Inn

Zalo Screen Number: The Key to Vietnam Market

Vietnamese spend far more time on Zalo every day than the average amount of time spent messaging. If your target users are Vietnamese local C-end consumers, local e-commerce store owners or B2B dealers, Zalo is a must-choice channel.

**What can the screening service do on Zalo? **

• Check whether the number is registered with Zalo (open for detection).
• Determine whether it has been active recently (the active window can be specified).
• Identify user gender (supports male/female targeting).
• Export Zalo uid for inviting friends, joining groups or precise private messages.

Practical Tips: First obtain a batch of Vietnamese +84 numbers through “Global Number Generation”, then use Zalo to enable detection and filtering, and finally filter out male users who have been active in the past 30 days (for example, for mobile game promotion). A single task supports millions of numbers, which is extremely efficient.

Line Screen Number: Accurate access to Thailand and Taiwan

Line has a very high penetration rate in Thailand and Taiwan, and many companies use Line for customer service, promotions, and shopping cart push. But Line’s number pool is uneven, with a large number of numbers unused or canceled for a long time.

**What can the screening service do on Line? **

• Detect Line activation/validity status.
• Identify user gender.
• Export Line uid (can be used for subsequent official API or third-party tool access).

Application Scenario: Before the Thai e-commerce promotion, the operation used the number screening service to clean the mobile phone number pool in the CRM two weeks in advance. Only female users who had opened Line and been active in the past 30 days were retained, and then imported into Line’s official messaging system. The conversion rate was significantly improved.

Telegram filter number: cold start of cross-regional communities

Telegram is the most familiar community operation platform for people going overseas. Whether it is an encrypted community, a cross-border e-commerce alliance, or an independent website in the private domain, Telegram is the first choice for cold start.

**What can the filtering service do on Telegram? **

• tg activation detection (whether the number is registered with Telegram).
• tg active detection (active window can be specified, such as the last 7 days, the last 30 days).
• Gender/age field identification (for example, screening people around 30 years old - based on the age field in public information, non-ID card level accuracy).
• Export tgid for group promotion, channel subscription or robot private message.

Typical usage: Generate a batch of target country number segments from the global number generation module, submit the Telegram number screening task, select “Active in the past 7 days” and “Gender is male”, export the tgid, and then use a compliant invitation tool to pull into the community to achieve a quick cold start.

How to build the entire process from number generation to precise screening?

Number generation: two ways to obtain the target number pool

1. Randomly generated global numbers – Covering 240+ countries and regions, you can specify parameters such as country prefix and number segment digits. Generating is completely free.
2. Custom CSV Import – If you already have a ready-made number list (e.g. collected from trade show business cards, advertising forms), directly upload the CSV file.

Recommendation: First use random generation to build a “wide network”, and then use the screening service to clean out valid numbers according to the target platform. The generation process is free of charge and can be produced in large quantities.

Batch filter number: filter by platform, activity, gender

When submitting a screening task in the KK-DATA console, you can:

• Check multiple platforms at the same time (e.g. Zalo + Line + Telegram).
  -Set an active window (e.g. “Last 30 days”).
• Check the gender field (Male/Female/Unknown).
• Select export fields (whether to include uid, age, avatar, etc.).

The platform will automatically detect and return filtering results. A single task supports up to approximately 1 million numbers (the actual upper limit is subject to console prompts). After the task is completed, the balance will be deducted on a per-item basis (see the real-time price on the console for details).

Data deduplication and export: avoid duplication and waste

• Data Deduplication Warehouse: Automatically eliminate detected numbers across tasks to prevent repeated deductions.
• Multi-format export: Supports CSV, TXT and other formats, making it easy to import into CRM, email marketing systems or community management tools.

The entire process can be abstracted as: Generate (free) → Screen number (deducted per item) → Deduplication (automatic) → Export (free), all done in one assembly line.

Implementation points and common pitfalls

• Billing Mode: No subscription package, balance will be deducted on a per-item basis. Deposit USDT (TRC20), the minimum is about 50 USDT. New tasks cannot be submitted when the balance is insufficient. It is recommended to estimate the amount of tasks before recharging.
• Fees will be deducted after the task is completed – The balance will not be frozen when the task is submitted, and the fee will only be deducted based on the actual number of tests after the results come out.
• Unit price difference – Different platforms and different detection types (such as activated only vs activated + active + gender) have different fees. The real-time price of the console shall prevail.
• Be careful to identify fake customer service – Only the following channels are official:

FAQ

**Q: How much accuracy can the screening service guarantee? ** Answer: The number screening service is based on the platform’s official interface or protocol for detection, and the accuracy of the activation/active status is high; the gender field is inferred based on public information and is not 100% accurate. It is recommended to use it as an auxiliary orientation basis and not to rely on ID cards.

**Q: How many numbers can be screened at most at one time? ** Answer: The maximum number of numbers in a single number screening task is about 1 million (the specific upper limit is subject to the console prompts). If you need to process a larger scale, you can submit it in batches.

**Q: What can the uid exported after filtering (such as tgid/wsid/line uid) be used for? ** Answer: uid is the unique identifier of a user within the platform, which can be used to automatically invite members to join groups, send private messages (subject to platform usage policies), collect user portraits, etc.

**Q: Will the recharged balance expire? ** Answer: The balance is valid for a long time and has no validity limit; the deduction will only be carried out after the number screening task is completed, and multiple recharges are supported.

**Q: How to avoid being blocked by the platform due to account screening? ** Answer: The number screening service itself only detects the status of the number, does not actively send messages, and does not violate the terms of use of the platform. You should use the filtering results in a compliant manner to avoid mass harassment.
