US Telegram Number Screening Checklist: From Area Codes to Active Windows, Must-Check These 5 Steps Before Screening

When doing US Telegram marketing, ignoring a few key points before screening means spending money with poor results. This article provides a US TG number screening checklist, covering area code selection, active windows, data deduplication, and other check items to help you filter out active Telegram users and improve your overseas customer acquisition ROI.

What is US TG Number Screening? Why Do You Need a Checklist?

US TG number screening refers to using technical means to batch-check whether a batch of US phone numbers are registered on Telegram, whether they are active, and even identify gender. It is a fundamental data preparation step for overseas marketing teams before carrying out Telegram community operations, direct message promotion, and TG follower growth. Many teams submit numbers directly for screening without preparation, only to find later that either the area codes are wrong resulting in many unregistered numbers, activity is low, or duplicate numbers waste the budget. A clear checklist helps you avoid these pitfalls, making the results of each screening directly usable.

5 Must-Do Checks Before Screening

Screening is not simply “submit → wait → export.” Taking 10 minutes to check these 5 items before clicking the “Submit” button can make a world of difference.

Check 1: Does the Area Code Source Match Your US Business Target?

US number area codes (NPA, three digits) correspond to different geographic regions. For example, +1 212 is Manhattan, New York; +1 310 is West Los Angeles; +1 305 is Miami. If your business targets Texas users but you screen a large number of New York area codes, even if you find active numbers, the subsequent silence rate will be high. Suggestions:

Select area codes by target state/city: In KK-DATA’s global number generation feature, after selecting “United States,” you can filter by area code prefix (e.g., 212, 310, 305, etc.). If you have your own numbers (e.g., customer phone numbers exported from CRM), upload the CSV directly.
Coverage strategy: Random nationwide generation is suitable for broad brand exposure, but for local community building, be sure to细分 to the city level.

Check 2: Active Window – 7 Days or 30 Days?

The “active window” in Telegram screening refers to how many days back a user has been online. A short window (7 days) yields numbers with high response rates and good tag quality, but fewer in quantity; a long window (30 days) yields more quantity but may include zombie accounts that log in occasionally. How to choose?

Marketing Scenario	Recommended Active Window	Reason
Short-term promotions (e.g., 3-day flash sale)	7 days	Users are online frequently, higher probability of opening DMs
Long-term brand exposure / community building	30 days	Wider coverage, allows users to respond slowly
Test samples / small batch verification	7 days	Quickly verify area code effectiveness, reduce waste

Note: Active window logic may vary slightly across platforms (Telegram/WhatsApp/iMessage). Refer to the actual options in the KK-DATA console.

Check 3: Has the Data Been Deduplicated?

Repeatedly checking duplicate numbers is the most common budget waste. For example, the same batch of numbers collected from three different channels might have only 600,000 unique entries out of 1 million submitted each time. Useless checks consume 400,000 quotas. Suggestions:

Clean in advance: Use KK-DATA’s data deduplication warehouse. Import once before all tasks; the system automatically deduplicates and records history. Subsequent tasks will automatically skip already checked numbers.
Cross-deduplication: If you run both TG and WhatsApp screening simultaneously, you can deduplicate in the same warehouse to avoid cross-platform duplicates.

Check 4: Are the Number Formats Clean?

Common format issues:

With or without the international prefix (+1)? It is recommended to include +1 consistently; the system will automatically recognize the country, reducing errors.
Containing spaces, hyphens, parentheses? Should be cleaned to pure digits (e.g., +1 212-555-1234 change to 12125551234 or +12125551234).
Very short (less than 10 digits) or very long (>15 digits) numbers should be removed. KK-DATA supports batch format validation; invalid formats are automatically filtered upon upload.

Check 5: Is the Budget and Balance Sufficient?

Before submitting a task, the console will display an estimated cost based on the number of numbers and selected detection types (TG registration, TG activity, TG gender, etc.). Ensure your balance is ≥ the estimated cost; otherwise, the task will fail to submit. It is recommended to deposit a minimum of about 50 USDT (USDT TRC20), topping up as needed to avoid idle balance. Unit prices can be viewed in real-time on the official website billing page or the console.

How to Build an Actionable US TG Number Screening Checklist?

Integrate the above 5 checks into a single reference checklist. Copy it into your project management tool and check off each item before every screening:

No.	Check Item	Key Points	Done
1	Area Code Match	Confirm area codes correspond to target state/city; or import own numbers from CRM	☐
2	Active Window	Select 7 or 30 days based on marketing rhythm (short-term promotions choose 7, long-term choose 30)	☐
3	Data Deduplication	Clean historical data in the deduplication warehouse to avoid duplicate charges	☐
4	Format Cleaning	Standardize to pure digits starting with +1, remove abnormal formats	☐
5	Budget Confirmation	Check console estimated cost, ensure balance ≥ that value	☐

This checklist is suitable for team collaboration. An operator or data analyst can review it before each screening task begins.

Practical Steps for US TG Number Screening Process

Using the KK-DATA platform as an example, demonstrate the complete process from number preparation to export. KK-DATA supports a “Generate → Screen → Export” pipeline without switching between multiple tools.

Step 1: Prepare Numbers (Generate or Import)

There are two ways:

Global Number Generation: In the console, select “Number Generation,” choose country United States, enter the prefixes or area codes you need, and the system will generate numbers for free (no charge). Supports custom ranges (e.g., first 100,000 numbers in the 212 area code). After generation, click “Submit for Screening” directly.
Upload Own Numbers: Create a CSV file with the first column containing numbers (with +1), then upload it under “Screening Tasks → New Task → Import Numbers.”

Pro Tip for Doubling Efficiency

Before each task, clean old data through the data deduplication warehouse to avoid duplicate charges. The console allows you to view historical task results and compare activity changes across tasks.

Step 2: Set Screening Parameters

In the “Screening Tasks” section:

Check “TG Registration” (detect if registered on Telegram).
Check “TG Activity” and select 7 or 30 days from the dropdown.
Optionally check “TG Gender” (identify via profile picture), supports export of Male/Female/Unknown categories.
The system will automatically display the estimated cost. Confirm sufficient balance, then submit.

Step 3: Export Results and Use for Marketing

After the task completes (usually minutes to hours, depending on quantity), download the CSV or TXT from “Task Records.” The CSV contains:

Number, TG registration status, activity status, gender, tgid (Telegram internal ID), and other fields.
The tgid can be used for subsequent targeted sending or imported into other tools for secondary filtering.

After export, you can directly connect to your delivery tools (such as Mass DM software or community bots) to start private messaging or group joining operations.

Avoid These Two Screening Pitfalls

Screening only for “Registration” without “Activity”: Numbers that only pass registration detection may be zombie accounts, leading to extremely low DM open rates later.
Ignoring area code selection: Relying solely on “Random Nationwide Generation” may lead to overly concentrated regions; it is recommended to segment by target city/state.

Common Misconceptions and Notes After Screening

Many teams make these mistakes after getting results:

Neglecting tgid usage: The tgid is Telegram’s unique internal ID, more stable than a phone number. If you plan multiple group sends or tag management, prioritize saving the tgid.
Screening all numbers at once: It is recommended to test in batches. First, use a small batch (1000-5000 numbers) to verify area codes and active window effectiveness, then scale up.
Task interruption due to insufficient balance: If the balance is insufficient after submission, the task will queue until the balance is topped up. It is recommended to maintain a balance covering at least 2-3 task volumes.
Falling for fake customer service: Official customer service only contacts through designated channels (e.g., https://t.me/kkdata_robot). Any unsolicited DMs requesting passwords or transfers are scams. Always verify through the official website or console channels.

Frequently Asked Questions

Q: When screening US TG numbers, should the specific number include the country code (+1)?
A: It is recommended to include the country code +1; the system will automatically recognize the country, reducing format errors. If the original data is pure 10-digit numbers, you can batch add +1 before importing.

Q: Which is more cost-effective: 7-day or 30-day active window?
A: For short-term promotional activities, 7 days is recommended for higher immediate response rates; for long-term brand exposure, 30 days can expand coverage. Specific pricing is subject to real-time console prices.

Q: Are the screened tgids useful? How to use them?
A: Yes, they are useful. The tgid (Telegram unique internal ID) can be used for targeted sending or imported into other tools for secondary filtering. The exported CSV includes the tgid field.

Q: Can I bulk generate US numbers and then use those numbers to screen for TG registration?
A: Yes. KK-DATA supports a one-stop operation of “Global Number Generation → Submit for Screening → Export Results.” Number generation is free; screening is charged per number entry.

Q: How do I know the results after screening?
A: The platform provides Telegram notifications; after task completion, a result link is automatically sent. You can also log in to the console and download from the “Task Records” page.
