US Active WS Number Field Dictionary: Status, Activity, Gender, Age and Platform ID Interpretation Guide

In North American overseas customer acquisition, US active WS numbers (i.e. US active WhatsApp numbers) are golden data for reaching high-quality users. However, after many teams get the screening results, they are faced with a bunch of fields but don’t know how to interpret them, resulting in a waste of data value. This article starts from the actual fields of the KK-DATA platform and explains the meaning of number status, activity, gender, age and platform ID one by one to help you accurately filter US WS active data and target target customers.

What is a US active WS number? ——Core data for overseas customer acquisition

US Active WS Number refers to a US number that has been tested and confirmed to be active on WhatsApp. The so-called “active” usually refers to online, sending messages or other behaviors within a configurable time window (such as 7 days, 30 days). The core difference between this type of number and ordinary “activated” numbers is that: The reach rate, open rate and reply rate of active numbers are significantly higher, which is the preferred data for brand private messages, community recruitment, independent station promotion and other scenarios.

For cross-border e-commerce and B2B SaaS overseas teams, obtaining US WS active numbers in batches can effectively reduce the cost of invalid outbound calls and improve marketing ROI. Number screening platforms (such as KK-DATA) use multi-dimensional detection to classify numbers into activated, valid, inactive, active and other statuses, along with metadata such as gender, age, platform ID, etc. to help you quickly extract US active WhatsApp numbers from massive numbers.

US Active WS Number Field Dictionary - What does each field represent?

The following fields are from the export results of the KK-DATA console. The fields of different tasks (Telegram/WhatsApp/Line, etc.) are slightly different. This article takes WhatsApp US active number detection as an example.

Number status field: the difference between activated, valid and invalid

Status	Meaning	Marketing Value
Activation	This number has been registered with WhatsApp, but it has not been verified whether it is a real person and is being used continuously	You can try to send messages, but there may be a canceled or zombie account
Valid	After real-time confirmation, the number is still available to receive messages on WhatsApp	Reachable, but need to pay attention to activity
Invalid	The number is not registered or has been logged out, messages cannot be sent	Filter directly to avoid waste

• Activated is the most basic status, indicating that the number exists, but is not necessarily active. For US active WS number screening, it is recommended to first filter out invalid numbers through the “activation” test, and then conduct further activity detection.
• Effective usually means that the number can receive messages normally at the time of detection, but it still needs to be combined with the active window to determine the user’s usage frequency.
• Invalid numbers should be completely eliminated, and numbers with undetected status may also be marked as unknown.

Operation Suggestion: Prioritize numbers with “valid” status, and then further stratify according to the activity field.

Activity field: How to define “active” and active window

The activity field directly identifies whether the number has any behavior within the specified time window. KK-DATA supports setting active window, such as 7 days, 14 days, and 30 days. The shorter the window, the higher the activity of the number, but the smaller the number; the longer the window, the greater the number, but the quality of the activity decreases.

• Active: Online or messaging behavior within the setting window is the core condition for US WS active number.
• Inactive: The number exists but there is no activity in the window. It may be a sleeping user or has left.
• Unknown: Unable to determine active status (such as privacy settings restrictions).

Interpretation Tips: If you are doing a short-term promotion (such as a 7-day flash sale), it is recommended to use a 7-day active window; if it is a long-term brand operation (such as community maintenance), a 30-day active window will suffice, covering a wider user pool.

Gender and age fields: Interpret the orientation ability of people around 30 years old

The gender and age fields are based on platform open data and model inference, and can be used for crowd targeting, but are not precise ID card levels. The gender identification field of KK-DATA returns “male”, “female” or “unknown”, and the age field returns a number (such as 25, 30, 35) or an interval value.

Suppose you need to target male users “about 30 years old”, you can filter: gender = male and age BETWEEN 25 AND 35. The age field is suitable for rough stratification and is not recommended for judgments accurate to single digits. Common Misunderstanding: Treating the age field as 100% accurate, in fact the model error usually fluctuates by ±3 years.

Platform ID field: Export purpose of WhatsApp ID (wsid)

The wsid is a globally unique identifier assigned to the number within the WhatsApp platform, which can stably identify the user across devices and time. After exporting the wsid you can:

• Secondary docking: Create user portraits in CRM and match them with historical data.
• Precise Reach: Combined with some API tools, use wsid to send messages directly (not affected by number change).
• Removal: Avoid the same user from being detected or marketed multiple times.

In the export file of KK-DATA, the wsid field is usually “wsid” or “whatsapp_id”, and the format is pure number. Note: There is no one-to-one correspondence between wsid and phone number. The same user can have multiple numbers but only one wsid, so wsid is more suitable as a unique key.

How to interpret age dimensions such as “about 30 years old” in the US WS active data?

A reasonable usage of the age field is hierarchical directional sinking. Assuming that your product’s target audience is American men aged 25-35, the screening steps are:

1. First generate or import a batch of US number segments (free) through the “US Number Generation” function, about 500,000.
2. Submit the WhatsApp ID screening task and select the detection type: activation + activity + gender + age. (See the real-time price on the console for fees)
3. After the task is completed, export CSV and filter in Excel: Active = True, Gender = male, Age BETWEEN 25 AND 35.
4. Export the wsid and number in the results for subsequent marketing.

**Why can’t it be accurate to the ID card level? ** Because age inference relies on platform public information (such as profile birthday, nickname, etc.), there are gaps and errors. It is recommended to treat the age field as a “probability of propensity” rather than an absolute truth.

What are the typical application scenarios for active WhatsApp numbers in the United States?

• Brand Private Message Promotion: Send product introductions and coupons to active users to avoid complaints.
• Community Attraction: Screen out active users and invite them to join WhatsApp groups to increase community activity.
• Independent station promotion: Combined with gender and age targeting, send promotional links to precise groups of people.
• B2B SaaS customer acquisition: Screen the decision-makers of American companies (such as those aged between 30-50) and reach them through private messages.
• Old Customer Activation: Use wsid to match CRM to find users who have purchased in the past but have not been active recently.

How to export and organize US WS active number data?

Export field selection: Which fields are most valuable to you?

Based on typical needs, the following field combinations are recommended:

Purpose	Recommended fields
Get only highly active users	Number, status (valid), activity (active), platform (WhatsApp)
Gender targeting	Number, activity, gender
Age + Gender Targeting	Number, activity, gender, age
Accurate secondary touch	Number, wsid, activity, gender, age

Cross-task deduplication: avoid wasting money on duplicate detection

KK-DATA has a built-in data deduplication warehouse function: when you submit a new task, the system automatically compares it with historical tasks, and the number that has been detected will not be deducted again. This means:

• If you have previously tested the “activation” status of a batch of US numbers and want to add “activity” testing later, the system will only charge the fee for the new test (activity detection) and will not charge the activation test fee again.
• When exporting across tasks, the deduplication warehouse automatically merges data to avoid repeated exports.

Common misunderstandings in the use of US WS active data

1. Misunderstanding 1: Thinking that “active” equals “reply immediately”. Active only means recent actions and does not guarantee instant response. Actual response rates also depend on message content and time of delivery.
2. Misunderstanding 2: Treat the age field as a precise value. As mentioned above, age inference has errors and should be based on a range rather than a single point.
3. Misunderstanding 3: Ignoring the role of wsid. Many teams only export numbers, making subsequent cross-platform matching difficult. It is recommended to export the wsid for each task.
4. Misunderstanding 4: Repeated testing of the same batch of numbers. Significant savings can be achieved by deduplicating warehouses.
5. Myth 5: Ignoring privacy compliance. When using active numbers for marketing, you need to comply with the laws of the target country (such as the US CAN-SPAM Act) to avoid complaints.

SEO interpretation of active WS numbers in the United States: Why is this keyword growing?

The increase in searches for long-tail words such as “US active WS number” and “US WS active number” reflects the rigid demand for data accuracy by overseas companies. The traditional “randomly generated” number pool has only very low activity, while the US active WhatsApp numbers screened through a professional platform have higher quality contacts. As competition in the North American market intensifies, mastering field interpretation capabilities will directly determine customer acquisition efficiency.

FAQ

**Q: What is a US active WS number? How is it different from a regular US number? **

Answer: An active WS number in the United States refers to a U.S. number confirmed to be on the WhatsApp platform after testing, and has online or messaging behavior within a certain time window (such as 7 days or 30 days). Ordinary numbers only represent the existence of the number, while active numbers represent higher reach and response rates, which are the core data for overseas marketing.

**Q: Can the age field be accurate to the ID card level? **

Answer: No. The age field is based on the platform’s public information and model inference, and can be used to roughly target people who are about 20-30 years old or about 30 years old, but it cannot be accurate to the specific age. It is recommended to use it for population stratification rather than precise identification.

**Q: How accurate is the gender field? **

Answer: The gender field is also based on model inference, and the accuracy depends on the data source and algorithm. It can be used for three types of orientation: male/female/unknown, but it is not recommended to rely on a single field for high-precision judgment. It is recommended to use it in combination with activity and platform ID.

**Q: What is the use of exporting wsid (WhatsApp ID)? **

Answer: wsid is an internal identifier of the WhatsApp platform. After exporting, it can be used for secondary docking, offline data matching or use with some API tools. Common uses include CRM data supplement, historical customer reactivation, etc.

**Q: Do I need to pay to generate a US number? How is the screening number billed? **

Answer: The global number generation function is free, and numbers for 240+ countries/regions can be generated for free. The sieve number is charged based on the actual number of tests. Different platforms have different unit prices for different test types. The specific price is subject to the real-time display on the console. Recharge uses USDT (TRC20), with a minimum of about 50 USDT.
