How to efficiently plan cross-country tg filtering tasks? Complete guide to country codes, number segments and batches

在出海营销中，tg过滤（Telegram号码筛选）是获取精准用户的基础环节。 However, many teams often encounter problems such as confusing country codes, scattered number segments, and a high proportion of invalid numbers when operating across countries. The balance is clearly spent, but the selected numbers have extremely low registration rates and insufficient activity. The root of the problem often lies in failure to plan the country code and number range in advance.

This article will start from the cross-border particularity of tg filtering, break down the three core links of country code, number segment generation, and batch planning, and provide practical steps for using KK-DATA to help you improve accuracy and control costs in Telegram filtering.

What is cross-country tg filtering? Why do we need to plan the country code and number range?

tg filtering refers to batch detection of the registration status, activity, gender and other attributes of Telegram numbers, and filters out valid numbers that meet marketing goals. In a cross-border scenario, target users are scattered in different countries, and the country codes (international area codes) of the numbers vary greatly:

• Different countries have different Telegram registration rates (for example, some countries in Southeast Asia have higher registration rates, while some countries in Europe and the United States have lower registration rates).
• The distribution of number segments is uneven (the registration rates of different number segments within the same country may also differ several times).
• Submitting mixed numbers from multiple countries will make it difficult to split the results, and it will be impossible to conduct targeted operations for each country.

Therefore, the core value of planning country codes and number segments is:

1. Reduce invalid detection: Only filter valid number ranges in the target country to avoid spending balance on numbers that “highly likely do not exist”.
2. Batch processing by country: It is convenient to split active users by country in the future, and conduct private message promotion in accordance with the local time zone/language.
3. Refined cost control: Under the itemized billing model, advance planning can significantly reduce the ineffective expenditure of a single task.

Core parameters for cross-country TG screening: country code and number segment analysis

Before performing telegram number filtering, you must first understand two basic parameters: country code (international area code) and number segment (number prefix range).

International standards and format considerations for country codes

• The number must contain the country code in the format of + plus the area code digits (e.g. +1, +86, +44). The number system without the country code cannot identify the specific country, which may lead to misjudgment or direct filtering.
• Common mistakes: forgetting to add +; using internal prefixes (such as 00) instead of international standards; repeatedly splicing country codes and numbers (such as +8686).
• 国家码与注册率的关系：通常活跃度高的区域（如俄罗斯、印尼、巴西、越南）注册率更高；而部分西欧国家由于本地通讯习惯影响，Telegram 渗透率偏低。

Recommended practice: Before generating or uploading a number, confirm the target country code through a reliable country code list (ISO 3166-1) and add + uniformly. KK-DATA’s global number generation module has automatically processed the country code format, and you can directly select the country code.

Segment generation: from random generation to custom import

The number segment refers to the number prefix (first few digits) after the country code. For example, the US number segment +1 415 represents the San Francisco area. There are often significant differences in the number registration rates in different number ranges.

KK-DATA provides two ways to generate number segments (both are free, and fees will be deducted only when submitting screening tasks):

• 随机生成：支持 240+ 国家，系统根据该国实际号段规律随机生成号码。 It is suitable for scenarios where the target country is wide and there is no preference for a specific number range.
• Customized CSV import: You can upload a list of known number segments (such as obtained from operator data or historical export) in a specified format, and the system will generate numbers in batches accordingly. Suitable for teams that already have an accurate number segment database.

How to plan batches by country to improve tg filtering efficiency?

A single tg filtering task supports up to about 1 million numbers. For cross-country projects, the tranche strategy directly affects cost and quality of results.

Batch by country: Reduce invalid number interference

Principle: Numbers with different country codes are submitted in batches.

• Why: When submitted together, the system will detect all numbers at once, but only the country code is marked in the result table, making it difficult for you to visually compare the differences in activity rates in different countries. After submission in batches, the results of each batch will be independent, making it easy to quickly assess the quality of the country’s code segment.
• Practical operation: For example, if the target is the United States + Indonesia, first submit a batch of segment No. +1 separately, and then submit a batch of segment No. +62. If the registration rate in one of the countries is extremely low, exploration in that direction can be suspended.

Batch by activity/gender: refined operation

Within a single country, it is recommended to adopt a secondary screening strategy:

1. Level 1: Submit the “Activation Detection” task and filter out unregistered numbers.
2. Level 2: Introduce the activated number into a new task, select “Activity Detection” (the active window can be specified, such as the last 7 days or 30 days) or “Gender Detection” (including fields such as gender, age, avatar, etc.).
3. Level 3: People around 30 years old can be filtered out based on the age field (note: the age field comes from the user’s public information, the accuracy is statistical level, not ID card level accuracy), and exported tgid for subsequent private messages or group operations.

This layered approach can minimize the need to spend your balance on activity detection of invalid numbers.

Use KK-DATA to complete the practical steps of cross-country tg filtering

The following takes three typical scenarios as examples to provide a list of reusable steps.

Scenario 1: Large-scale screening in a single country (such as India +91)

1. Log in to Application Console.
2. Enter “Global Number Generation”, select the country “India (IN)”, select “Randomly Generate” or “Generate by Number Segment”, set the number (for example, 500,000), and click Generate. Generate for free.
3. Copy or download the generated number list.
4. Create a new “Telegram Filtering Task”, select “Activate Detection” as the detection type, and submit the number. Estimated costs are shown in advance.
5. Wait for the task to be completed (can be received via Telegram notification).
6. Export the results (CSV or TXT), retaining the “opened” numbers.
7. Use these activation numbers to create a new “Activity + Gender” task and perform secondary screening.

Scenario 2: Small batch testing in multiple countries (such as Philippines, Malaysia, Thailand)

1. Generate numbers for three countries in sequence, with approximately 10,000 numbers generated for each country.
2. Submit three independent “activation detection” tasks.
3. Compare the registration rates of the three countries and choose the country with the highest level to further increase the volume.
4. If simultaneous detection is required, they can also be combined into one task, but it is recommended to separate them for data comparison.

Scenario 3: Targeting active people (tgid needs to be exported)

1. First generate the target country number segment, and get the activation list after activation detection.
2. Submit “Activity Detection”, set the activity window to “Last 7 Days”, and then superimpose “Gender Detection”.
3. The export field contains tgid (Telegram internal ID), which can be used for subsequent group invitations or private message API calls.

Cost and balance management suggestions for cross-country TG screens

KK-DATA adopts a per-item billing and no subscription package model, so costs are controllable.

• Recharge Threshold: The minimum is about 50 USDT (TRC20), and the balance will be automatically updated after arrival.
• Check the cost: The specific unit price varies depending on the platform (Telegram, WhatsApp, Line, etc.) and detection type (activation, active, gender), please see the real-time price on the console for details.
• Cost Control Tips:
  • Duplication Warehouse: Automatically remove duplicates between different tasks to prevent the same number from being detected and deducted multiple times.
  • Use free generation first: There is no cost to generate number segments. Generate them in batches first and then decide whether to filter.
  • Hierarchical screening: activation first, then activity and gender, to reduce invalid secondary detection.

Common pitfall reminders and best practices

Common Mistakes	Consequences	Correct Practice
The country code is missing +	The number is misjudged or cannot be recognized	Automatically added when generating, or manually checked
The number range is too large (such as the national number range)	The proportion of invalid numbers is high and the balance is wasted	Test in small batches first, confirm the registration rate and then scale up
All numbers are mixed and submitted together	Unable to separate and analyze the activity rate	Submit in batches by country
Forgot to remove duplicates	Repeatedly detect the same number, resulting in multiple deductions	Use a deduplication warehouse or remove duplicates yourself before uploading
Forcibly submit when the balance is insufficient	Task submission failed	Recharge before submitting. It is recommended to always have sufficient balance

Best Practice: Small batch testing (10,000 to 50,000 items) → Optimization parameters (country, number segment, detection type) → Large batch execution (within 1 million items). Use Telegram Bot to receive task completion notifications and track progress at any time.

FAQ

**Q: What fields can tg filter detect? ** Answer: Supports detection of registration status (activation), activity (windows such as the last 7 days/30 days can be specified), gender, age, tgid, avatar, etc. Different detection types correspond to different export fields, which are subject to the console export file. Note that the age field comes from the user’s public information, and the accuracy is not ID card level.

**Q: When filtering across countries, does the country code have to have a ”+” sign? ** Answer: Yes. The number must contain the complete international area code (such as +86), otherwise the system may not be able to correctly identify the country, resulting in misjudgment or invalid detection. It is recommended to use the generation module of KK-DATA, which will automatically add +.

**Q: How many numbers can be submitted for a single tg filtering task? ** Answer: The maximum number of single tasks is about 1 million. If the amount is exceeded, it is recommended to submit it in batches. For example, 2 million numbers can be split into two tasks.

**Q: Is there any charge for generating a global number? ** Answer: Global number generation is completely free. You can generate random numbers or customized number segments from 240+ countries in the console, and fees will be deducted only when submitting screening tasks. For detailed prices, please refer to the real-time price on the console.

**Q: How can I confirm that my number has not been repeatedly detected? ** Answer: KK-DATA provides the “data deduplication warehouse” function, and the system automatically records all detected numbers. When submitting a new task, if the number history has been detected, the fee will not be deducted again. You can also manually upload the detected list for comparison.
