Overseas Marketing Number Pool Supplement Strategy: Continuous Generation, Deduplication, and Efficient Screening Guide

Is your overseas marketing number pool constantly running low? Large batches of numbers becoming invalid, duplicate detection eating up your budget, and new leads failing to replenish in time—these difficulties all point to one core issue: an imperfect number pool supplement strategy. Whether you are doing Telegram group promotions, WhatsApp private message lead generation, or multi-platform cross-reach, the number pool is like a reservoir; if water only flows out and not in, it will inevitably dry up. This article will break down a sustainable number pool supplement plan for you from three stages: generation, deduplication, and screening.

Why Does Your Number Pool Keep Draining? — Understanding the Necessity of “Number Pool Supplement”

The depletion of a number pool is not accidental but the result of multiple factors:

• Natural Number Expiration: Telegram and WhatsApp accounts may be deactivated due to prolonged inactivity, violation of platform rules, or users changing numbers. Statistics show that a typical business number pool can lose 10%–20% of its numbers per month.
• Platform Restrictions and Detection: After bulk sending messages, some unregistered or unsubscribed numbers lower delivery rates and may even trigger platform banning risks. Screening is a necessary prerequisite to filter out invalid numbers.
• Diminishing Returns from Repeated Use: When the same number is reached multiple times, user attention decreases and block rates increase. A sound strategy is to use numbers once and then discard (or reduce contact frequency), supplementing with fresh numbers.
• Seasonal Fluctuations in Target Markets: Certain industries (e.g., cross-border e-commerce during promotion seasons) need to quickly expand coverage. Generating and screening numbers on the fly is essential to keep pace.

Core Insight: Number pool supplement is not a one-time task but a routine operation that runs throughout the entire overseas customer acquisition lifecycle. It consists of three closely connected stages: Generation → Deduplication → Screening. Below, we will break down each step in detail.

Three Core Stages of Number Pool Supplement: Generation – Deduplication – Screening

A healthy number pool supplement pipeline should operate as steadily as a factory assembly line:

1. Generation → Continuously produce raw numbers (free operation).
2. Deduplication → Avoid spending money on numbers that have already been screened (key to saving costs).
3. Screening → Filter out high-value leads based on platform, activity, gender, and other dimensions (output results).

If any stage breaks—for example, generating without screening, or screening without reusing already screened data—it will lead to inefficiency and wasted budget. Let’s dive into each stage.

Generation: Building New Number Sources from Scratch

Where do raw numbers come from? KK-DATA offers three free methods:

• Random Generation: Covers 240+ countries/regions. Specify the quantity as needed, and the system automatically generates valid number combinations.
• Number Range Generation: For specific country or operator number ranges, input the starting and ending number range to batch-generate consecutive numbers.
• CSV Import: If you have self-collected numbers (e.g., business card numbers from exhibitions, existing customer lists), you can upload a CSV file to directly enter the screening pipeline.

Generation is free; only screening is charged. This means you can try out different regions and number ranges without limit, then focus on screening once you find high-conversion areas.

Deduplication: Avoid Wasting Balance on Repeated Screening

Many people overlook this step: the same number may be screened repeatedly across different batches, incurring charges each time. The deduplication repository acts as a “blacklist database of already screened numbers.” All subsequent screening tasks will automatically skip these numbers.

To use it, simply create a repository in the console, upload all historically screened numbers, and enable the “Cross-Task Deduplication” option. Each time you submit a new screening task, the system will automatically compare and remove duplicates, charging only for the new numbers.

Screening: Accurately Filter by Platform, Activity, and Gender

The goal of filtering is to turn “possible numbers” into “usable leads.” KK-DATA supports multi-platform screening:

• Telegram Screening: Can detect whether a user is registered (active), can receive messages (valid), is active (specify online within 7/15/30 days), and gender (based on avatar recognition). Also supports exporting tgid.
• WhatsApp Screening: Detect whether a number is registered on WhatsApp, supports exporting wsid.
• iMessage, RCS: Suitable for Apple users and carrier-level SMS detection.

When selecting detection types, tailor them to your marketing scenario. For example, for Telegram group promotions, it is recommended to check “Registered + Active + Gender” together; the numbers screened will have a higher conversion rate.

Step 1: Continuously Generate Numbers — How to Ensure a Steady Stream of New Blood

The generation module is the starting point of number pool supplementation. Below are operational steps for three scenarios.

Use Random Generation to Cover Broad Regions

Applicable Scenario: You need to quickly test a new market or have no specific knowledge of number ranges in the target country.

Steps:

1. Log in to the Application Console, go to the “Number Generation” page.
2. Select country (multiple selection allowed), e.g., Brazil, India, Indonesia.
3. Enter the quantity to generate (e.g., 5000 per country, total 15000).
4. Click “Generate,” wait a few seconds, and the number list will appear.
5. Directly export or click “Submit for Screening” to start a screening task.

Key Points: Random generation offers broad coverage, but the effective rate in a specific area may be low. It is advisable to start with a small batch (2000–5000) to test the effective rate before scaling up.

Use Number Range Generation to Precisely Target High-Potential Areas

Applicable Scenario: You know a specific city or operator’s number range (e.g., Brazil Vivo range 55 21 9xxxxxxx) and want to bulk acquire numbers from that range.

Steps:

1. On the “Number Range Generation” page, select the country and enter the start and end numbers (e.g., 5521987650000 to 5521987659999).
2. The system automatically calculates the quantity (10000 in this example).
3. Click Generate. Note: Numbers within the range may contain invalid numbers, but generation is free.
4. It is recommended to submit for screening immediately after generation to avoid local storage redundancy.

Import Your Own CSV for Supplementation

Applicable Scenario: You already have a self-collected number list or received number files from partners.

Steps:

1. Prepare a CSV file. Recommended format: one column of numbers (international format, e.g., +5521987654321), no header.
2. On the “Number Generation” -> “Import CSV” page, upload the file.
3. After parsing, the system displays the number count and deduplication results (compared with the repository data).
4. After confirmation, you can directly submit for screening.

Tip: It is best to deduplicate the CSV in Excel first to avoid wasting screening slots with duplicate data.

Step 2: Deduplication and Reuse — Cross-Task Number Deduplication Saves More Than Just Money

Many teams fall into the trap of “screen first, review later”: they upload millions of numbers at once for screening without considering the duplication rate. They later find that 30% of the numbers had already been screened, wasting balance. The deduplication repository is designed to solve this problem.

Create a Repository and Enable Cross-Task Deduplication

Steps:

1. Go to the “Data Deduplication Repository” module in the console.
2. Click “Create Repository,” give it a label (e.g., “2025 Q1 Main Pool”).
3. Upload all historically screened numbers (it is recommended to export the full list from the first batch of screening results, including both valid and invalid numbers, because invalid numbers have already consumed balance).
4. Check “Enable Cross-Task Deduplication” and save.
5. For each subsequent screening task, the system will automatically compare against the repository, skip existing numbers, and display the actual charged quantity.

Effect: Once enabled, every number will be screened at most once. If the same number appears in different tasks, it will not be charged again.

Regular Cleanup and Repository Maintenance

It is not advisable to let the repository grow indefinitely. Suggestions:

• Monthly: Archive or delete abandoned numbers (e.g., invalid numbers not used for more than 6 months) to control repository size.
• Weekly: Sync newly screened numbers to keep the repository up to date with the latest screening results.

Step 3: Batch Screening — Convert New Numbers into Valid Leads

After generation and deduplication, the final step is to feed raw numbers into the screening engine and output usable leads.

Submit a Telegram Screening Task

Steps:

1. In the console, select “Screening Tasks” -> “New Task”.
2. Select platform as “Telegram”.
3. Upload numbers (supports TXT/CSV, or directly select from generation records).
4. Check detection types: It is generally recommended to at least select “Registered” and “Active.” If gender filtering is needed, also select “Gender.”
5. The system displays an estimated cost (e.g., 10,000 numbers × unit price = XX USDT). Be sure to confirm the amount and ensure sufficient balance.
6. Click Submit. The task enters a queue, and upon completion, you will receive a Telegram notification (requires binding @kkdata_robot in advance).

Submit a WhatsApp Screening Task

Steps are similar. Note the WSID export option: if you need to send messages directly on WhatsApp, you can also export wsid (WeChat-style user ID) for subsequent integration with the official API.

Key to Success: Use Telegram notifications after task completion. No need to refresh the page; it is convenient and efficient for batch operations.

Number Pool Supplement Checklist (Daily/Weekly Execution Points)

Incorporate the following actions into your team’s workflow to significantly reduce the risk of number pool depletion:

• Daily: Check console balance. If below 100 USDT, recharge USDT (TRC20) promptly.
• Daily: After receiving screening results, calculate the valid number percentage for the batch. If the effective rate is below 15%, consider changing the generation area or number range.
• Every Monday: Pull new numbers from the global number generation module (random or number range). Quantity should be approximately 2 times the weekly screening demand (accounting for effective rate loss).
• Weekly: Import all screened numbers from the previous week (including both valid and invalid) into the deduplication repository to avoid duplicate screening next week.
• Before each task submission: Confirm that the “Cross-Task Deduplication” option is enabled and check if the estimated cost is reasonable.

Best Practices and Common Mistakes

The following insights come from experienced operators—you can copy them directly:

• Best Practice: First use random generation to explore, then use number range generation to lock in high-yield areas. For example, start by randomly testing the effective Telegram rate in five countries; if you find that India and Brazil have an activity rate above 30%, subsequently generate number ranges targeting those two countries.
• Common Mistake 1: Generating numbers without screening, storing them locally. Raw numbers take up storage and may expire. Screen them as soon as possible (within 72 hours).
• Common Mistake 2: Ignoring deduplication, screening the same batch of numbers repeatedly. This results in budget overruns of 50% or more.
• Common Mistake 3: Believing that all “active” numbers will directly convert. Activity only indicates the number is online; it does not imply interest in your marketing message. Combine gender, group behavior, and other dimensions for better targeting.

Frequently Asked Questions

Q: When supplementing the number pool, how many new numbers should I generate each time?

A: It depends on your daily screening volume and target conversion rate. A general rule is to base it on weekly demand. For example, if you need 5000 valid Telegram numbers per week, with an average pass rate of 30%, generate about 17,000 numbers for screening each time.

Q: Can the deduplication repository automatically match numbers in different formats?

A: Yes. The system will automatically remove differences such as international prefix symbols, spaces, brackets, etc., and convert them to the E.164 standard format (including the + country code) for deduplication. While it’s recommended to clean data locally before uploading, the repository’s intelligent matching handles most formatting issues.

Q: Will the number quality decrease if I don’t screen them immediately after generation?

A: Numbers themselves are static, but the account status on platforms (Telegram/WhatsApp) may change over time. It is generally recommended to complete screening within 72 hours after generation to ensure timeliness. For long-term retention, screen them first and store the results in a list.

Q: Do different platform screening unit prices affect the supplement strategy?

A: Yes. Telegram screening is usually cheaper than WhatsApp and offers more detailed activity detection. If your budget is limited, prioritize supplementing the Telegram number pool first, then expand to WhatsApp when your balance is sufficient. Refer to the real-time unit prices displayed in the console.

Q: Can the “deduplication and reuse” strategy directly filter out previously invalid numbers?

A: Not automatically. The deduplication repository only marks numbers as “already screened.” It does not assume that invalid numbers should never be used again. You can manually add invalid numbers to a blacklist (some platforms support this), or re-screen the same number if the detection type changes. It is recommended to record and delete invalid numbers without resubmitting them.
