U.S. Data Special Topic Navigation: Complete Guide to Number Segment Generation, Multi-Platform Screening, Duplication Removal and Customer Acquisition Scenarios

In the wave of global customer acquisition, US data has always been a high-value resource that overseas companies are competing to seize. The United States has a population of more than 330 million, mobile Internet penetration is extremely high, and social platforms such as Telegram, WhatsApp, iMessage, and Line have a huge user base. Whether it is cross-border e-commerce, independent website promotion, or social media operations, accurate U.S. number data can significantly improve reach efficiency and conversion rates. However, how to get a real US number? How to filter out users who are open, active or even of a specific gender? How to avoid wasting costs due to repeated testing? These problems often leave teams helpless. This topic navigation will focus on the generation of US number data, multi-platform screening, gender recognition, deduplication export and industry applications, providing you with a set of practical operation guides, while connecting the core functions of the KK-DATA platform to help you quickly build a US customer acquisition data pipeline.

Why is US data a key resource for acquiring customers overseas?

Users in the U.S. market have strong payment capabilities, high activity on social platforms, and are far more receptive to content-based and service-based products than other regions. Whether it is promoting cross-border e-commerce discount codes through Telegram communities or using WhatsApp private messages to reach B2B customers, the quality of US customer acquisition data directly determines marketing ROI. However, the number lists on the market are often mixed with a large number of invalid, unregistered or long-term inactive numbers. Direct mass sending not only wastes resources, but may also trigger platform risk control and lead to account bans. Therefore, a complete U.S. data link must contain three links:

Generate or obtain US number segment
Multi-platform screening (activation, active, gender, etc.)
Remove duplication and export (to avoid repeated deductions and facilitate secondary marketing)

The subsequent chapters of this article will break down the operation methods and tool support of each link one by one, and focus on how the KK-DATA platform can complete the above process in one stop.

Number segments and generation methods of US phone numbers

Basic knowledge of US number segments

U.S. phone numbers follow the North American Numbering Plan (NANP), in the format NPA-NXX-XXXX, which is a 3-digit area code + 3-digit exchange number + 4-digit user number. Common area codes include New York (212/646), Los Angeles (213/310/323), Chicago (312/773), Houston (713/832), etc. Understanding the distribution of number segments can help to generate numbers in specific areas. For example, the 212/646 number segment can be generated specifically for the Chinese community in New York.

Use the KK-DATA global number generation function to obtain the US number segment

KK-DATA’s [Global Number Generation] (https://kkdata.cc/) function supports random generation of numbers in 240+ countries/regions, covering all area codes in the United States. You only need to select “United States” and the target area code (or random across the United States) on the console to generate up to about 1 million candidate numbers at one time. The generation process is completely free and does not consume your balance. The generated number list can then be submitted for screening tasks.

Operation steps:

Log in to Application Console
Enter the “Number Generation” module and select the country “United States”
Select the area code as needed (multiple choices are available) or check “All area codes”
Set the generation quantity and click Generate
The system generates a CSV file and automatically saves it to the “My Number” library

CSV import and batch generation of custom number segments

If you already have a ready-made US number segment (such as a list purchased from a third-party data provider), you can also directly upload the CSV file for screening. KK-DATA supports importing up to about 1 million custom number lists. The file format requirements are: the first column is the phone number, no formatting is required (unified to international format +1xxxxxxxxxx). Once imported, the list can be used as an input source for filtering tasks.

It is free to generate, and the screen number will be deducted according to the item.

The global number generation function does not consume the balance; after the generation is completed, the number screening task can be submitted, and the fee will be deducted from the balance based on the actual number of detections. For details of the unit price, please see the real-time price of the console.

How to detect the “activated” and “active” status of a US number?

Telegram US number screening: activation detection and active window settings

Telegram is one of the most commonly used platforms by Chinese Americans, technical people, and cross-border community operators. When screening US numbers on Telegram, two core indicators need to be distinguished:

Activation detection: Determine whether the number has been registered in Telegram (that is, it has an account).
Activity Detection: Determine whether the account has login or usage records within the specified time window (such as 7 days, 30 days). The more active the number, the better the private message reach rate.

In KK-DATA, you can freely set the active window (such as “active in the past 7 days”) when submitting the Telegram screening task. The system will also return tgid (Telegram internal ID, which can be used for subsequent precise targeted push) and other optional fields (such as gender, age, etc.).

WhatsApp US number detection: validity and activity identification

WhatsApp’s penetration rate in the United States is also very high, and it is especially suitable for cross-border e-commerce and independent customer service scenarios. WhatsApp screen can detect the following status:

Activated (valid): Whether the number is registered with WhatsApp
Active: Is there any recent online record?
Gender/Avatar: Some accounts can identify the user’s gender and avatar URL.

In the detection results, in addition to the basic activation/valid Boolean values, fields such as wsid (WhatsApp internal ID) and user nickname will also be provided.

US number verification on iMessage, RCS, Line, Zalo and other platforms

In addition to Telegram and WhatsApp, American users also widely use platforms such as iMessage (comes with Apple devices), RCS (Android Rich Media Communication), Line (popular in Japanese, Korean and some Chinese circles), Zalo (mainly used in Vietnamese communities, but also has a certain base in the United States).

KK-DATA provides independent detection channels for each platform. For example:

iMessage: Detect whether the number activates iMessage (blue bubble)
RCS: Check whether the RCS protocol is supported, suitable for Android mass sending
Line: Detect activation, activity and gender (Line gender field has higher accuracy)
Zalo: Detects activation, activity and gender, suitable for Vietnamese-American customer acquisition

A single task supports up to about 1 million items

Please pay attention to the data volume limit when submitting in batches. Large files can be split into multiple tasks. It is recommended that a single submission be controlled within 900,000 items to ensure processing speed.

Gender and demographic identification of US data

Telegram gender detection and age field interpretation

In the Telegram screening results, if the personal information filled in by the account contains gender and date of birth, the system will extract and return these fields. However, special attention is required: Telegram’s gender data is not mandatory to fill in, and age is set by the user or estimated by the algorithm. The accuracy ranges from about 30% to 70%, and cannot be used as ID-level verification.

KK-DATA returns the gender detection along with the age field. For example, you can filter out American numbers with a gender of “female” and ages 25 to 35 for use in beauty and skin care promotions targeting young women. The description of “about 30 years old” refers to the age field falling in the range of 28 to 32, rather than being an exact integer of 30 years old.

Gender and demographic attribute data of WhatsApp/Line/Zalo

Different platforms have different support for gender information:

Platform	Gender Field Availability	Additional Fields
Telegram	High (about 40% of accounts have data)	Age, avatar URL, tgid
WhatsApp	Medium (avatars are visible for some accounts)	wsid, nickname
Line	Higher (high ratio of avatar and gender disclosure)	uid (internal ID)
Zalo	Medium (account public information required)	uid, activity level

Through cross-platform filtering, you can combine data from multiple dimensions to build a more three-dimensional user profile. For example, US numbers that have both Telegram and WhatsApp activated and are marked as female in Line can be screened out for multi-platform linkage marketing.

The age field is an estimated range, non-ID card level accuracy

The age field in gender detection is estimated by an algorithm model and can be used for crowd targeting, but cannot be used as a basis for accurate identity verification. It is recommended to combine age cross-validation on multiple platforms or confirm through follow-up communication.

Data deduplication and export: improve efficiency and avoid repeated deductions

In multiple screening tasks, the same number may appear in multiple batches. If the number is retested every time it is submitted, the balance will be wasted. KK-DATA has a built-in data deduplication warehouse that automatically records the detection history of each number on each platform. When you submit a new task, the system will identify the numbers that have already been detected and skip directly or only detect new platforms, thereby saving costs.

The export link supports CSV and TXT formats. Commonly used export fields include:

phone number
Platform (such as Telegram, WhatsApp)
Activation status (true/false)
Active status (true/false)
Active time window (such as “last 7 days”)
Gender
age
Platform internal ID (tgid, wsid, uid, etc.)
Avatar URL (some platforms)

The exported file can be directly imported into a CRM system, email marketing tool or custom mass sending script. In order to facilitate secondary marketing, it is recommended to export by platform group, for example, export the number of “Telegram active and female” as a separate file for targeted push.

Industry application scenarios and best practices for customer acquisition data in the United States

Industry scenarios	Typical requirements	KK-DATA recommendation process
Cross-border e-commerce (independent website)	Promote promotions to US buyers	Generate US number → Filter out active WhatsApp users → Export wsid → Drop site link via WhatsApp API private message
Social media operation (Telegram community)	Invite precise users to join the product community	Generate designated area code number → Filter out Telegram activity + gender/age → Export tgid → Use robots to invite batches
B2B overseas (LinkedIn outreach)	Obtain the contact information of legal persons or business decision-makers	It needs to be combined with LinkedIn to expand overseas customers (not the director of this platform), but it can be cross-verified through the number (associated email address) that has been opened for LinkedIn
North American Chinese market promotion	Promote local life services for the Chinese community	Select the Chinese area code (such as New York 212/646) → Generate a number → Filter out Telegram/WeChat/Line activation → Export as a private message

Best Practice Advice:

Small batch testing first: Select 1000~5000 pieces of data for the first time, observe the opening rate and activity rate of each platform, and then decide the direction of expanding the scale.
Screening by platform and in stages: Don’t screen all platforms at once. Screen the most important platforms first (such as Telegram), and then screen the users who have passed through other platforms (such as WhatsApp) a second time to reduce costs.
Make good use of the deduplication warehouse: Don’t abandon duplicate numbers. You can deduplicate them across tasks before submitting them to a new platform for testing.
Abide by the platform rules: Avoid sending large amounts of messages in a short period of time, and combine real-life speaking skills with a reasonable sending frequency.
