Screen number service SEO pillars: Cross-platform social screen number, number generation and data deduplication full process guide

Overseas marketing teams face the same problem every day: they have a large number of mobile phone numbers, but they don’t know which numbers are valid, which users are active, and which people belong to your target group. Blindly sending marketing information not only wastes costs, but may also trigger platform bans. It is against this background that the Screening Service was born - it helps the team to accurately target high-converting leads and reduce invalid push by batch testing the registration status, activity, and even gender and age information of numbers on various social platforms.

Why do overseas teams need screening services? Because infrastructure varies greatly from market to market. European and American users prefer WhatsApp and iMessage, Southeast Asian users heavily use Telegram, Line, and Zalo, while Latin American markets rely on WhatsApp. If there is no number screening process, a lot of the SMS fees, API call fees, and even manpower time you invest will be consumed on invalid numbers. The core values of screening services include:

• Verify number validity: Check whether the number is activated on the target platform (such as Telegram, WhatsApp).
• Filter active users: Filter out zombie accounts that have not been online for a long time through activity detection (such as tg active).
• Identify user portraits: Some platforms support the export of gender, age and other fields to help targeted marketing (such as Line male users).
• Data Deduplication: Avoid repeated detection of the same number in multiple tasks and protect your balance.

Next, we will dismantle the various capabilities of the screening service in the system and provide practical operation guidelines.

What is the screening service? Why does the overseas team need it?

In short, Screen Number Service is a data verification and cleaning platform. You submit a batch of mobile phone numbers, and the system will call the underlying capabilities of each platform (non-public API, but through compliance technology) to return the social platform registration status, activity, and some public portrait information of each number.

The main scenarios for overseas teams to use the screening service:

1. Telegram community recruitment: You hope to attract a group of target users into your TG group, but only those who have registered a Telegram number can join. Through the “tg activation” detection, unregistered numbers can be eliminated in advance and the success rate of joining the group can be improved.
2. WhatsApp Private Message Marketing: When sending promotional information to WhatsApp users, if the validity of the number is not verified, a large number of messages will be sent to unregistered or invalid numbers, which not only wastes money, but may also cause the number to be marked as spam. The push delivery rate of the filtered number list is increased by 3-5 times.
3. Line accurately targets male users: Targeting the Japanese, Korean and Taiwanese markets, Line’s gender recognition function allows you to push male consumer products only to male users, greatly increasing the conversion rate.
4. Zalo Vietnam market icebreaker: The mainstream social network in Vietnam is Zalo. Through “zalo activation” detection and activity judgment, ads or private messages can be targeted at active users.

Without the screening service, overseas teams are like shooting arrows while blindfolded - you may hit the bull’s-eye, but the probability is extremely low. With screen numbers, every penny spent counts.

Detailed explanation of multi-platform social screening numbers

The platforms currently supported by the screening service cover mainstream overseas destinations, including but not limited to: Telegram, WhatsApp, Line, Zalo, iMessage/iOS, RCS, Viber, Facebook, Instagram, Binance, LinkedIn, etc. Each platform can detect different types, which are explained one by one below.

Telegram Screen: activation, activity and gender data

Telegram is the largest platform for acquiring customers overseas, especially in Russia, Southeast Asia, and the Middle East, with a large number of users. The screening service provides the following test types for TG:

• tg activation (registration detection): Determine whether the number has registered a Telegram account. This is the most basic and commonly used test to help you filter out unregistered numbers.
• tg active (can specify window): On the basis of activation, further detect whether the user is online in the latest period of time (such as 7 days, 30 days). Active users are more likely to respond to messages and are suitable for private message promotion scenarios.
• telegram gender data: Some TG accounts will disclose gender and age information. The filter service can extract these fields, and the age field can be used to filter people around 30 years old. Please note: This data is based on user public information and cannot reach ID card level accuracy, but it has sufficient reference value for targeted marketing.
• tgid export: The Telegram internal user ID (tgid) can be exported at the same time in the detection results, making it easier to directly call the TG API for subsequent operations (such as adding contacts).

WhatsApp / Line / Zalo Screen ID

These three platforms respectively cover the global popularization, Japan, Korea, Taiwan, Southeast Asia and Vietnam markets, each with its own characteristics.

Platform	Supported detection types	Key export fields	Main applicable markets
WhatsApp	activated, active, gender (part)	wsid, activation status	Global (except China, Japan and South Korea)
Line	Open, valid, gender (can target men)	uid, status	Japan, Taiwan, Thailand
Zalo	open, active, gender	uid, status, gender	Vietnam

• WhatsApp Screener: Check whether the number is enabled for WhatsApp (activated) and whether it has been online recently (active). Some numbers can return gender. The exported field contains the WhatsApp internal ID (wsid) for subsequent sending of messages via the WhatsApp API.
• Line Screen Number: Line’s “valid” detection usually means that the account is still available. Gender detection can clearly distinguish between male and female, and is suitable for e-commerce sellers to promote sports equipment, electronic products, etc. to male users. After exporting the uid, it can be used to add friends to the official Line account.
• Zalo Screen Number: Zalo is the national application of Vietnam. Through “zalo activation” and “zalo activity” detection, merchants can efficiently screen out local Vietnamese users who are using Zalo and avoid sending information to inactive or canceled numbers. Gender detection is also supported.

Other platforms: iMessage / RCS / iOS / Facebook / Instagram, etc.

In addition to the above three main forces, the screening service also covers the following platforms:

• iMessage / iOS Device: Detects whether the number is registered for iMessage and is in iOS device (blue bubble) status. iOS users usually have strong spending power and are suitable for the promotion of high-priced categories.
• RCS: Rich media communication service of Android system, detects whether the number has RCS enabled. In European and American markets, RCS is gradually replacing SMS.
• Viber: An instant messaging application with a certain number of users in the Philippines and Eastern Europe.
• Facebook / Instagram: Detects whether the number is associated with a Facebook or Instagram account, but generally can only return the activated status, without including more granular activity or gender.
• Binance/LinkedIn: Targeted detection for cryptocurrency investors or professionals, used for Web3 project promotion or B2B customer acquisition.

The actual available detection types and export fields may be adjusted according to platform policies. Please refer to the field list on the Console task creation page.

How to connect global number generation and screening?

Many overseas teams face another pain point: there is no ready-made target number pool. You may know that you want to expand into the African market, but you don’t have a list of local mobile phone numbers in Africa. The global number generation module built into the sieve platform solves this problem.

Number generation method: random, number segment, CSV import

• Randomly generated: Supports 240+ countries/regions. Enter the country code and region (optional), and the system will randomly generate valid segment numbers for the region. The generated numbers are free, only subsequent numbers will be deducted.
• Number segment generation: If you know the number segment of a certain operator (for example, Indonesian Telkomsel starts with 0812), you can specify the number segment prefix and the number of numbers to generate in batches. The numbers generated in this way are closer to the real operator allocation range.
• Customized CSV import: If you have a list of mobile phone numbers (such as potential customer numbers collected from exhibitions), directly upload the CSV file, and the platform can initiate the screening task after identifying the numbers.

Screening task submission process and estimated cost

1. Choose to generate or upload: First obtain the target number through the number generation module, or directly upload your own list.
2. Select the detection type: For example, “tg activation” or “whatsApp active + gender”, the system will immediately display the estimated cost (unit price × quantity) to facilitate budget control.
3. Submit task: Up to about 1 million numbers can be submitted for a single task. Exceeds can be submitted in batches.
4. Waiting for results: The task usually takes a few minutes to dozens of minutes to complete, depending on the number of numbers and how busy the platform is. Receive notifications via Telegram when completed.
5. Export results: Support downloading in CSV, TXT and other formats.

The “Generate → Filter → Export” pipeline eliminates the need for the team to source numbers from outside and reduces the cost of acquiring each lead.

Result export: CSV, TXT and other formats

The export file contains all the fields you selected in the task. Common fields include:

-Mobile phone number (international format)

• Platform status (activated/not activated/error)
• Activity (recent online time interval)
• Gender (male/female/unknown)
• Age (some platforms)
• tgid / wsid / uid and other platform IDs
• Detection time

Once exported, it can be used for CRM import, API triggering messages, or uploading as a custom audience for an advertising platform.

Data deduplication warehouse: How to avoid wasting balances through repeated detection?

Cross-task number deduplication is an easily overlooked but very practical function in the number screening service. Suppose you have checked the Telegram activation status of a batch of numbers last month, and this month you have used the same batch of numbers to check the WhatsApp activity. If there is no deduplication, you may be charged again for the same number (even if it is just repeated detection on the same platform). But through data deduplication warehouse:

• The system will compare the number submitted this time with the number list of all completed tasks in history.
• If a number has already been tested for the same “Platform + Detection Type”, the number will be marked as “duplicate”, no repeated deductions will be made, and historical results will be directly quoted.
• If the detection type is different (for example, last time it only detected activation, but this time the detection is active), it will be re-detected and fees will be deducted.

Usage tips:

• Before submitting a new task, confirm the option to turn on the deduplication warehouse (usually it can be checked in the task settings).
• For long-term operating number pools, it is recommended to regularly screen numbers across the entire platform, and then store the results in a deduplication warehouse. Subsequently, you only need to supplement and detect new numbers.

Billing model for screen number service: no subscription, per-item deduction, USDT recharge

Overseas teams hate being forced to subscribe to a package. Screening platforms usually adopt a model of no subscription and payment by item.

• Balance Recharge: Only USDT (TRC20) recharge is supported, with a minimum of about 50 USDT. After recharging, the balance will be credited to your account in real time.
• Deduction timing: After each screening task completes, the system deducts the cost of the actual number of detected items from the balance. Unfinished tasks will not be billed.
• Unit price description: Different platforms and different detection types have different unit prices. For specific prices, please see Console Real-time Price or Official Website Billing Page. This article does not make up any unit prices.
• Insufficient balance: If the balance is insufficient to cover the estimated fee when submitting a task, it will not be submitted and needs to be recharged first.
• Advantages: Pay as much as you use, increase the amount during peak periods, and avoid wasting it during off-seasons. Suitable for teams with processing volumes ranging from hundreds of thousands to hundreds of millions of numbers.
