Multi-Platform Number Screening Capability Table: Comprehensive Comparison of Telegram, WhatsApp, iMessage, and Other Social Platforms

Overseas marketing teams often face a practical problem when screening phone numbers: different social platforms define “validity” very differently. Telegram requires checking registration, activity, and even gender; WhatsApp only needs to confirm whether the number is registered; iMessage and RCS each have their own judging rules. Looking only at a single platform’s capability description can easily cause you to overlook key dimensions during selection, only to find that the number quality doesn’t meet your needs after launch.

At this point, a multi-platform number screening capability table helps you quickly clarify which detection types each platform supports and which it does not, allowing you to precisely match your marketing scenarios and avoid wasted investment. Based on the detection capabilities currently available in the KK-DATA console, this article organizes a cross-platform comparison table, along with detailed explanations and selection recommendations for each platform.

Core Number Screening Capability Comparison Table (Telegram / WhatsApp / iMessage / RCS)

The table below lists the core capability dimensions of the four mainstream social platforms for number screening. Data source: KK-DATA console (app.kkdata.cc) and official documentation (docs.kkdata.cc). For specific unit prices, please refer to the real-time display when creating a task in the console.

Capability Dimension	Telegram	WhatsApp	iMessage	RCS
Registration Detection	✅ tg registration (whether registered on Telegram)	✅ Whether the number is registered on WhatsApp	✅ Whether Apple device has iMessage enabled	✅ Whether RCS feature is enabled
Validity Detection	✅ tg valid (can receive messages)	✅ Valid number (registered means valid)	— (registered means valid)	—
Activity Detection	✅ tg active (7/15/30 days, configurable)	—	—	✅ Carrier activity detection
Gender Identification	✅ Via profile photo analysis	—	—	—
ID Export	✅ tgid export	✅ wsid export	—	—
Carrier Detection	—	—	—	✅ Empty number / carrier detection

Note: ”—” in the table indicates that the platform currently does not support this detection, or the detection type is meaningless (e.g., iMessage registration implies validity, so no separate validity check is needed). The activity window definitions (e.g., 7 days, 15 days, 30 days) are based on the console configuration.

Telegram Number Screening Capability Details

Telegram is one of the most commonly used platforms for community management and direct message promotion. Its screening dimensions are the most comprehensive:

• tg registration: Checks if the number is registered on Telegram. This is the most basic step; only registered numbers can proceed with subsequent operations.
• tg valid: Based on registration, determines if the number can receive messages (not banned, not deactivated, etc.). Valid numbers are users you can actually reach.
• tg active: Supports specifying a time period (e.g., last 7 days, 15 days, 30 days) to check if the user has been online or active. Activity is a key indicator for community tiered targeting; highly active users tend to have higher response rates.
• Gender identification: Infers gender by analyzing the user’s profile photo (requires a photo with clear gender characteristics). Accuracy is affected by photo quality; it is recommended to use in combination with other dimensions.
• tgid export: Exports the Telegram unique ID (tgid) for each number, making it convenient to send messages or join groups via API later.

Example use case: Filter out “users who have been online in the last 7 days and whose profile photo clearly indicates male” for specific product promotion.

WhatsApp Number Screening Capability Details

WhatsApp has extremely high penetration in many regions worldwide and is another major platform for direct message marketing. Its screening dimensions are relatively simple:

• Whether the number is registered on WhatsApp: Checks if the phone number has an active WhatsApp account. This is the basic “registration check.”
• Valid number: Based on registration, confirms that the number can receive messages (not banned). Note that WhatsApp currently does not support activity detection, so you cannot determine if the user has been online recently.
• wsid export: Exports the WhatsApp unique ID (wsid) for each number, useful for WhatsApp Business API usage.

Reminder: Since WhatsApp activity detection is not yet available, if your marketing requires filtering “active users,” consider combining with other platforms or using historical behavior data as a supplement.

iMessage and RCS Number Screening Capabilities

iMessage and RCS serve as supplementary channels, suitable for specific customer groups (e.g., Apple users, high-end markets).

• iMessage: Primarily checks if an Apple device has iMessage enabled. A successful registration check means the number can receive iMessage messages; there are no dimensions like activity or gender.
• RCS: Checks if the phone number supports RCS (Rich Communication Services). It also provides empty number / carrier detection to determine if the number genuinely exists and which carrier it belongs to. RCS activity detection specifically refers to whether the carrier side supports RCS services.

These two types of detection are typically used to supplement scenarios not covered by Telegram/WhatsApp, such as users who do not use instant messaging apps but do use SMS.

How to Choose a Screening Platform Based on the Capability Table?

Different marketing goals correspond to different capability requirements. You can quickly identify which detection types to enable based on the table below.

Scenario 1: Telegram Community Management – Focus on Activity and Gender

If you are adding members to Telegram groups or promoting channels, your main concern is whether users are “active” and whether they match your target audience. In this case, prioritize using:

• tg activity detection: Specify a number of days (e.g., 7 days) to filter only users with recent behavior.
• Gender identification: Enable this if you need to differentiate content or products by gender.

Avoid unnecessary detections: tg registration (since validity detection already includes registration), tgid export (export on demand). This improves data quality while saving detection costs.

Scenario 2: WhatsApp Direct Message Promotion – Core Focus on Number Validity

The core of WhatsApp marketing is ensuring that the number you send to is indeed registered on WhatsApp. The capability table shows that WhatsApp only supports registration/validity detection, so you only need to select:

• WhatsApp valid number detection (or directly choose “Whether the number is registered on WhatsApp”)
• wsid export (if you need to send via API later)

Do not waste balance on activity detection (it does not exist), and do not select irrelevant detection items from other platforms.

Scenario 3: Omni-Channel Campaign – Use a Unified Capability Table Across Platforms

If you run campaigns on multiple platforms simultaneously (e.g., TG + WhatsApp + iMessage), you can upload numbers once and select multiple detection types in the KK-DATA task configuration. For example:

• For the same batch of numbers, simultaneously perform “tg valid + tg active (7 days) + WhatsApp valid + iMessage registration”
• The system will detect each separately, and the results for each detection will be displayed independently and eventually merged for export.

This creates a complete pipeline from generation to screening to export, eliminating the need for repeated operations.

Common Misconceptions and Precautions about the Screening Capability Table

• Misconception 1: Activity detection equals real-time online status
  Activity detection is based on the user’s last online time (or recent usage record); it does not mean they are online at the current second. For example, “7-day active” on Telegram means the user logged in at least once in the past 7 days, not that they are online now. Pay attention to timeliness when launching campaigns.

• Misconception 2: Gender identification is 100% accurate
  Gender identification relies on profile photos. It may be inaccurate due to unclear photos, multiple people in the photo, or the user changing their photo. Use gender as a supplementary filter, not the sole criterion. Test error rates on a small batch before large-scale use.

• Misconception 3: iMessage can detect all Apple devices
  iMessage detection requires that the number has been enabled for iMessage on an Apple device. Some devices using inactive numbers or those using only SMS will not be detected.

• Misconception 4: RCS detection equals empty number detection
  RCS detection includes empty number/carrier detection, but its core purpose is to check if the number supports RCS services. If you only need empty number detection (whether the number is valid), RCS detection may not be optimal because some valid numbers do not support RCS.

• Misconception 5: The unit prices in the capability table are fixed
  The unit prices for each detection type may change due to platform policies and real-time resource availability. Always refer to the estimated cost shown when creating a task in the console. Confirm the amount before submitting.

How to Optimize Your Customer Acquisition Budget Using the Capability Table?

KK-DATA charges per record, with no subscription plans. This means you only pay for the detection items you actually use. Combined with the capability table, you can:

• Select only the detection items you need: For example, if you only need to filter TG valid numbers, enable only “tg valid”; if you need to send messages to female users, add “gender identification.”
• Avoid duplicate detection: If a number has already been detected in another task, you can use the data deduplication warehouse to skip it automatically and avoid double charging.
• Test small batches before running full-scale tasks: First test different detection combinations on a small batch, compare results to determine the optimal configuration, then run the full task.

For example, if you originally planned to run four detections simultaneously (“tg registration + tg valid + tg active + gender identification”), the capability table reveals that “tg registration” is already covered by “tg valid” (since a valid number is necessarily registered). You can skip the registration check and save that expense directly.

Future Capability Expansion and Platform Trends

Social platforms’ number screening capabilities continue to evolve. Currently, WhatsApp activity detection is not yet available, but there have been industry discussions about its need; iMessage support for large data volumes may gradually expand. RCS services are growing rapidly in overseas markets, and more dimensions (e.g., activity tiering) may be added in the future.

We recommend regularly checking the “Detection Type” update page in the KK-DATA console, or joining the official channel @kkdata_channel for first-hand notifications. You can also share your needs with customer service @kkdata_cc to help the platform improve its capabilities.

Frequently Asked Questions

Q: What is the data source for the multi-platform number screening capability table?
A: The data comes from the list of detection types currently available in the KK-DATA console and the official documentation (docs.kkdata.cc). Platform capabilities are continuously updated, so please refer to the real-time console page for the most accurate information.

Q: Will WhatsApp activity detection be available in the future?
A: Currently, no timeline has been announced. Keep an eye on the “Detection Type” updates in the console or contact customer service @kkdata_cc for updates.

Q: What is the essential difference between iMessage screening and RCS screening?
A: iMessage detection checks whether an Apple device has iMessage enabled; RCS detection checks whether a phone number supports Rich Communication Services (RCS) and also provides empty number/carrier detection. They target different device ecosystems: iMessage is limited to Apple users, while RCS supports Android and iPhone (starting from iOS 18).

Q: Can the same batch of numbers be screened across multiple platforms at the same time?
A: Yes. In the KK-DATA task configuration, you can select multiple detection types (e.g., TG valid + WS valid + iMessage registration), but each detection is billed independently. The system will return results for each platform in a single pass.

Q: What do “score” or “confidence” mean in the capability table?
A: Some detection types provide a “score” or “confidence” field (e.g., confidence for gender identification, score for activity). For details, see the documentation at docs.kkdata.cc.
