Global US Number Generation: Bulk Generate US Numbers and Filter Active Telegram/WhatsApp Users

When it comes to overseas customer acquisition, the United States remains one of the highest-value markets. Whether for cross-border e‑commerce, standalone site promotion, or community management, obtaining active Telegram or WhatsApp users in the US is a key factor in improving conversion rates. However, directly purchasing pre‑existing US number lists often suffers from outdated data, high duplication rates, and a lack of validity or activity labels. Global US Number Generation offers a smarter solution: using tools to bulk‑generate virtual numbers based on US number‑block rules, then combining them with Telegram and WhatsApp screening capabilities to filter out real users who are registered, active, or even of a specific gender. This article uses KK‑DATA as an example to detail the complete pipeline from generation to screening, helping overseas teams efficiently build a precise audience pool.

What Is Global US Number Generation?

“Global US Number Generation” refers to using a number‑generation tool to bulk‑produce virtual numbers that comply with US phone number rules (such as area codes 212, 310, 415, and their corresponding number ranges) but have not yet been assigned to real users. These numbers are not from real users; they serve as candidate data sources for subsequent screening tests. KK‑DATA’s Global Number Generation module covers 240+ countries/regions, with the US being one of the most frequently used options.

The generation module seamlessly integrates with the screening module to form a complete “generate → screen → export” pipeline. Generated numbers are free; charges are deducted per record only when a screening task (e.g., checking Telegram registration status, WhatsApp validity) is submitted and completed. This model allows overseas teams to obtain a pool of target‑region, unverified numbers at minimal cost, then filter them for high‑value active users through precise screening.

Why Do Overseas Customer Acquisition Teams Need US Number Blocks? — The Potential of the US Telegram/WhatsApp Market

The United States is one of the largest social media markets globally. Although WhatsApp’s market share is lower than in Europe and Latin America, 2024 data shows the US has approximately 80 million WhatsApp users, and the number is steadily growing; Telegram has about 50 million users in the US and is popular among younger demographics for its privacy and group features. For overseas companies, using US number blocks for screening delivers two core values:

1. Precise targeting of local users: US number blocks directly correspond to the target market, avoiding the waste of invalid detection and marketing costs caused by random international numbers.
2. Filterable activity and gender: By checking Telegram activity (7‑/15‑/30‑day active windows) and gender identification, you can further narrow down users most likely to engage.

Imagine a scenario: you plan to promote an e‑commerce app to US users on Telegram. Sending spam directly is inefficient and risks account suspension. But if you already have a set of numbers generated from US blocks and confirmed active within the last 7 days via Telegram activity checks, you can target them with direct messages or community invitations, significantly boosting conversion rates.

How to Bulk‑Generate US Number Blocks Using a Global Number Generation Tool

KK‑DATA’s global number generation module is simple to operate. Below are step‑by‑step instructions for quickly producing US numbers.

Select Country “United States” and Set Generation Parameters

Log in to the KK‑DATA Console and go to the “Global Number Generation” module.

1. Select United States from the country/region list.
2. Set the generation mode: supports “Random Generation” and “Specify Prefix.” Random generation evenly samples from all active US area codes; specify prefix allows you to enter a specific area code (e.g., 212 for New York City, 310 for Los Angeles), ideal if you want to focus on a single city or region.
3. Enter the desired number of numbers to generate. There is no upper limit, but we recommend generating no more than 500,000 at a time to facilitate subsequent batch screening.

Import Custom US Number Blocks (CSV Format)

If you already have a list of US number blocks (e.g., area code + prefix from carrier public data or industry datasets), you can upload a CSV file for bulk generation. The file should contain one prefix per line (without country code, e.g., 212123); the system will automatically fill in the remaining digits to create complete numbers. This method is especially useful for users who need precise control over specific blocks (e.g., New York, San Francisco, Chicago).

Preview and Bulk Generation

Click “Generate Preview” to view the first 100 sample numbers. Once you confirm the format and blocks are correct, click “Start Generation.” A generation task typically completes within 1‑3 minutes (almost real‑time for under 100,000 numbers). After completion, the number list is saved under “Generation Records” and can be downloaded or directly imported into the screening module.

After Generating US Numbers, How to Filter Active Telegram/WhatsApp Users?

Once numbers are generated, the next step is screening. KK‑DATA supports parallel screening across multiple platforms — you can check Telegram and WhatsApp simultaneously to save time.

Telegram Screening: Check Registration, Activity, and Gender

In the “Screening Task” module, import the newly generated US number list, then select the following check types:

• TG Registration (account check): Verifies whether the number has registered a Telegram account. Numbers that are not registered incur no charge.
• TG Activity: You can specify an activity window (7 days, 15 days, 30 days, etc.). The system uses an API to determine if the account’s last online time falls within the window. For marketing scenarios, we recommend a 7‑day activity filter to ensure users are recently active.
• Telegram Gender Identification: Determines the user’s gender via Telegram avatar (facial recognition algorithm). This enables gender‑specific marketing — e.g., beauty content for female users, gaming/tech content for male users.
• TGID Export: While checking validity, also retrieve each number’s Telegram User ID (TGID), making it easier to send messages or add to groups via API later.

WhatsApp Screening: Check Valid Numbers and Export WSID

Similarly, import the number list and select the WA Valid check type. The system verifies whether the number has registered a WhatsApp account. If valid, you can also export the WSID (WhatsApp internal ID) for precise outreach via WhatsApp Business API or other channels.

Parallel Multi‑Platform Screening and Result Export

When creating a task, you can check multiple screening types for both Telegram and WhatsApp at the same time. The system submits them together, tests separately, and finally generates a combined result report. Results can be exported in CSV or TXT format for easy import into CRM, EDM, or auto‑messaging tools.

Pipeline from Generation to Screening: How to Reduce Wasted Duplicate Checks?

A common mistake made by overseas teams is regenerating and re‑checking numbers every time they need fresh data, leading to wasted balance from duplicate checks. KK‑DATA’s built‑in data deduplication warehouse solves this problem perfectly.

How the Data Deduplication Warehouse Works

The system automatically records all numbers that have been checked and their results. When you submit a new task, it first compares against the warehouse, automatically excludes already‑checked numbers, and charges only for new numbers. This means:

• If you previously checked a batch of 10,000 US numbers, accidentally importing the same list again will not result in duplicate charges.
• Deduplication works across tasks and across platforms (e.g., a number already checked for Telegram will be automatically skipped when checking for WhatsApp).

Best practice: After generating each batch of numbers, first import them into the deduplication warehouse (via the “Data Warehouse” module or by linking to a task), then submit the screening task. This minimizes duplicate checks and saves balance.

How to Control Costs? Billing Logic for US Number Generation and Screening

KK‑DATA uses a pay‑as‑you‑go model with no subscription, so all costs are fully controllable.

Stage	Charged?	Description
Global Number Generation	Free	Regardless of how many numbers are generated, no charges apply; unlimited generation
Screening (e.g., TG registration, WA valid)	Per record	Charges are deducted only for numbers successfully checked after a screening task is submitted. Invalid numbers are not charged (but note: “invalid” is different from “not checked”; the actual billing rules are based on the console)
Data Deduplication Warehouse	Free	Automatic deduplication, no extra fees
Balance Top‑up	Minimum ~50 USDT (TRC20)	No subscription plans; top‑up and balance is automatically updated; tasks cannot be submitted if balance is insufficient

Cost estimation example: Suppose you need 10,000 active US Telegram users. First, generate 500,000 US numbers for free. Then submit a TG registration check (assuming unit price is X per record — see console for exact price). If you check 500,000 numbers and the valid rate is 5% (i.e., 25,000 registered), the actual charge is 500,000 × X. Next, from those 25,000 registered numbers, filter for 7‑day activity. Assuming an activity rate of 40%, you’ll be charged again for 25,000 × Y (activity check prices may differ). The result is 10,000 active numbers. The entire cost is transparent; you can view the estimated fee before submitting a task.

Best Practices and Precautions for US Number Generation and Screening

The following insights come from real feedback from many overseas teams and can help you improve efficiency and reduce costs.

Number Format and Block Selection Tips

• Format requirements: All numbers must include the international country code. For the US, that’s +1 followed by the area code and number (e.g., +12125678901). The system automatically adds +1 during generation — no manual entry needed.
• Prioritize common area codes: High‑traffic cities such as New York (212/646/332), Los Angeles (310/424), Chicago (312/773), Houston (281/832) generally have higher densities of real users, leading to higher effective rates after screening. In contrast, sparsely populated areas like Alaska (907) and Hawaii (808) have lower hit rates.
• Avoid over‑concentrating on the same block: If checks show that all numbers in one area code are either all invalid or all valid, it may indicate that block is heavily used by virtual operators. Consider switching to a different block.

Plan Task Quantities Wisely to Avoid Wasting Balance

• Submit in batches: A single screening task supports up to ~1 million numbers, but we recommend batches of no more than 100,000. This way, if a batch has poor quality blocks, the loss is smaller.
• Combine with data deduplication: For each new generation, first compare against the deduplication warehouse to exclude already‑checked numbers. Periodically clean the warehouse to remove outdated, low‑value data and keep it efficient.
• Use result feedback: After completing a batch, analyze the rates of validity and activity. If a particular block has an extremely low valid rate, avoid it in future generations.

Frequently Asked Questions

Q: Are the generated US numbers real user numbers?

A: No. They are virtual numbers that conform to US number‑block rules and are used for subsequent screening tests. Only numbers that are registered on Telegram or WhatsApp are considered valid. Unregistered numbers are not charged (but note: invalid results are not charged, yet the checking action still incurs cost; please refer to the actual rules in the console).

Q: Can I upload my own US number list for screening?

A: Yes. Besides using the “Global Number Generation” module, you can directly upload a TXT or CSV list in the screening task. The system automatically identifies and deduplicates before screening. If you already have a number pool (e.g., lists from other channels), you can use the screening capability to validate and check activity.

Q: What is the maximum number of US numbers I can screen in one task?

A: A single task supports up to ~1 million numbers. If your numbers exceed this limit, submit multiple tasks and use the data deduplication warehouse to avoid duplicate checks.

Q: How do I confirm that active users in the screening results can be contacted?

A: Activity detection only indicates that the account was online within the specified window; it does not imply consent to receive marketing messages. Always comply with the target platform’s usage policies (e.g., Telegram’s bulk messaging limits, WhatsApp’s 24‑hour conversation rule) to avoid account bans from mass harassment. Consider using two‑way contact robots (e.g., @kkdata_robot) for compliant direct messages.

Q: How long does it take for a USDT top‑up to reflect?

A: Usually, after a TRC20 transfer is confirmed, the balance updates automatically within 1‑15 minutes. If it takes longer, contact official customer service @kkdata_cc or submit a ticket via the two‑way contact robot.
