A Practical Guide to Screening Millions of US Telegram Numbers: Large-Scale Operations and Best Practices

When you have millions of US Telegram numbers in hand, facing a vast North American market but unsure how to efficiently verify their availability, activity, and gender characteristics, number screening becomes the most critical step in the customer acquisition chain. Whether you are running Telegram community management, direct message promotion, or building a B2B overseas user pool, large-scale number screening is not simply “submit, wait, export.” From number generation, task splitting to deduplication strategies, every step can be a pitfall. This article takes a million-level US Telegram number screening task as an example, combined with the core features of the KK-DATA platform, to break down the best practices for large-scale operations.

Why Screen Millions of US Telegram Numbers?

The US is a popular target market for overseas marketing, and Telegram has a huge user base in North America. Batch obtaining and verifying US Telegram numbers can help you:

• Precisely reach potential customers: Avoid sending messages to empty or invalid numbers, saving costs.
• Identify high-value users: Through activity and gender analysis, filter out recently online users for targeted outreach.
• Support large-scale customer acquisition plans: With millions of data points, you can quickly roll out campaigns for new user acquisition, re-engagement, or conversion.

However, the million-level scale also brings challenges: messy number sources, high verification costs, platform single-task limits, wasted balance from duplicate checks, etc. You need a streamlined solution, not just “click to screen.”

Preparations Required Before Screening

Before submitting your first task, ensure the following four items are ready.

Confirm Number Source and Format

KK-DATA supports two ways to import numbers:

1. Global Number Generation (Free): In the console, select country “United States,” and the system will automatically generate random numbers that conform to US number ranges (starting with +1, 10 digits without prefix). No cost for generation.
2. Custom CSV Import: If you already have data for specific number ranges (e.g., number tables purchased from third parties), organize them into a CSV file and upload, with one number per line in the format +1xxxxxxxxxx.

Regardless of the source, ensure numbers are in international format. Non-standard formats (e.g., missing country code, containing spaces or special characters) will cause screening failures.

Calculate Budget and Top Up Balance

Million-level screening fees are charged per number checked. Different check types (Telegram registration check, valid check, activity check, gender identification) have different unit prices. Please log in to the console to view real-time rates, or refer to the official pricing page. For example, for 1 million numbers, if only registration check is performed, the estimated cost will be shown before task submission.

We recommend dividing your budget into 2-3 batches for top-ups to avoid freezing a large amount at once. Use USDT (TRC20) for top-up, minimum about 50 USDT, and the balance will be updated automatically after arrival.

Prepare a Multi-Batch Task Plan

KK-DATA supports a maximum of approximately 1 million numbers per screening task. If your total number of numbers exceeds 1 million, you must split them into multiple subtasks. It is recommended to split by number range or data source, for example:

• Batch 1: Starting with +1 201 (500k)
• Batch 2: Starting with +1 202 (500k)
• Batch 3: Starting with +1 213 (remaining)

This facilitates progress management and allows for timely adjustments if a particular batch has issues.

How to Generate Millions of US Number Ranges?

If you don’t have an existing US number list, you can use KK-DATA’s global number generation feature to obtain millions of potential numbers at zero cost.

Use the Global Number Generation Tool (Free)

In the “Number Generation” module of the console, select country “United States,” set the quantity to generate (e.g., 500k), and the system will randomly generate valid numbers that comply with US number range rules. The generated results can be imported into a screening task with one click. This process is completely free; you only pay per number when the actual screening is performed.

Import Custom Number Range CSV

If you already know the target number range (e.g., a specific operator or a fixed prefix in a certain city), you can prepare a CSV file with three columns: prefix, start number, end number. For example, for US Verizon numbers starting with +1 908, fill in:

+1908,0000000,9999999

The system will automatically expand into full numbers and import. This method is suitable for users who require precise coverage.

Best Execution Strategies for Million-Level Tasks

When submitting large-scale screening tasks, pay attention to the platform’s limits and notification mechanisms.

Make Use of the 1 Million Single-Task Limit

If the total number of numbers is within 1 million, you can submit them as one task. If it exceeds, submit according to the previously planned batches. Note: After submission, the system will immediately lock the estimated cost, so the balance must be sufficient.

Set Task Completion Notification

Bind your Telegram in the console and enable “Task Completion Notification.” When a large-scale task is completed (which may take several hours), you will receive a Telegram message, eliminating the need to repeatedly refresh the page to check the status.

Monitor Task Progress and Balance Deductions

Each task deducts the balance in bulk upon completion. If you submit batches in sequence, ensure that the balance is still sufficient when submitting subsequent batches. For example, if batch one consumes part of the balance, batch two may fail due to insufficient balance. It is recommended to check the current balance before submitting each new batch.

Deduplication Repository: Avoid Repeating Checks and Wasting Balance

In million-level screening, cross-task number duplication is common (e.g., two batches contain the same numbers). KK-DATA has a built-in “Data Deduplication Repository” function: before submitting a new task, the system automatically compares whether the numbers in the task have been processed in historical checks, skipping duplicate numbers without charging.

This means you can safely import numbers from different sources without paying extra for overlaps. Especially when you have multiple batches, it is recommended to enable deduplication before submitting.

Result Export and Subsequent Actions

After screening is complete, the result set includes, for each number: registration status (Telegram registered), activity level (customizable 7/15/30-day window), gender identification (judged by avatar, only for some numbers), and tgid (Telegram internal ID). You can choose to export in CSV or TXT format.

• CSV format: Suitable for importing into CRM or Excel for secondary analysis.
• TXT format: Suitable for direct import into broadcasting systems.

The exported valid numbers (registered and active) can be directly used for Telegram community invitations or direct message campaigns. The tgid is a stable user identifier that can be used for targeted invitations into channels or groups.

Common Pitfalls and Avoidance Guide

1. Invalid number ranges leading to low efficiency: Some US number ranges (e.g., virtual operators) have extremely low registration rates. It is recommended to test the registration rate of a small sample of a number range first before generating the full quantity.
2. No deduplication across batches causing repeated charges: If you submit batches without enabling the deduplication repository, the same numbers will be checked multiple times. Make sure the deduplication feature is enabled before each task.
3. Insufficient balance interrupting tasks: When the estimated cost of a single task is high, ensure sufficient balance before submission; if other tasks consume the balance during execution, the task may pause or fail. It is recommended to top up in batches.
4. Ignoring activity window settings: The default activity check may be lenient. If you need recently active users (e.g., within 7 days), explicitly set the window; otherwise, you may get “abandoned” accounts.
5. Ignoring notification settings: Million-level tasks may run for several hours, and without notifications it’s easy to forget, leading to delays in exporting results.

Frequently Asked Questions

Q: How much does screening millions of US Telegram numbers cost?

A: Fees are charged per number checked, and different check types (Telegram registration, activity, gender identification, etc.) have different unit prices. Please log in to the console to view real-time rates. For example, for 1 million registration checks, the estimated cost will be shown before submission. It is recommended to top up sufficient balance in advance.

Q: What is the maximum number of numbers that can be checked in a single task?

A: Currently, the system supports a maximum of approximately 1 million numbers per single task. If your total number exceeds 1 million, please split it into multiple subtasks and submit them sequentially.

Q: Is number generation free? How is screening charged?

A: Yes, the global number generation feature is completely free and does not consume your balance. You are only charged for the effective number checks after you submit a screening task and the system completes the check, deducted from your balance.

Q: Which fields in the screening results are meaningful? Can tgid be exported?

A: The results include registration status, activity level (customizable 7/15/30 days), gender identification (judged by avatar), tgid, etc. Export is supported in CSV or TXT format. The tgid can be directly used for community invitations or message pushes.

Q: What happens if the balance is insufficient after submitting a task?

A: At task submission, the balance must be sufficient to cover the estimated cost, otherwise the task cannot be submitted. If other tasks consume the balance during execution causing insufficiency, the task may pause or fail. It is recommended to ensure sufficient balance to cover the full volume before submitting large-scale tasks.
