How to Start Number Screening? A Beginner’s Guide: From Registration to Completing Your First Screening Task (Including Checklist)

If you’re new to overseas marketing, you may have heard the term “number screening” but aren’t sure what it actually does or how to begin. Simply put, number screening is the process of batch-checking whether a list of phone numbers are registered on a specific social platform (such as Telegram, WhatsApp), whether those accounts are active, and even identifying the gender of the account holder. It is a prerequisite step for precise customer acquisition — not mass messaging, but first filtering out truly valid, reachable target users to avoid wasted sends and resource drain.

This tutorial is designed for beginners. It takes you from concept to hands-on execution, guiding you through your first number screening task. Whether you’re running a standalone site, doing community promotion, or managing an outsourced operations team, following the checklist and steps below will help you get started quickly.

What Is Number Screening? Why Beginners Need to Understand This Concept First

Number screening refers to submitting a batch of phone numbers to a platform to check their registration status, activity level, gender, and other information across different social apps. For example:

Check whether a number has a Telegram account (registration check)
Check whether that Telegram account has been active in the last 7 days (activity check)
Identify the gender from the account’s profile picture (gender identification)
Export the corresponding tgid or wsid for further targeted operations

Why must you screen numbers? In overseas marketing, many teams directly buy number lists or randomly generate numbers before adding friends or sending messages. The result is a high proportion of invalid numbers, unregistered accounts, or accounts that haven’t been active for a long time — leading to low friend-add rates and high account ban rates. Number screening acts as a filter, keeping only the highest-quality numbers and making every subsequent step far more efficient.

Key point: Number screening ≠ bulk messaging. Screening is the data preparation phase; bulk messaging is the execution phase. Without screening, bulk messaging is shooting in the dark.

What Do Beginners Need to Prepare Before Starting Number Screening? (Checklist)

Before logging into the console, confirm the following four items are ready:

List of numbers to be screened
- This can be customer phone numbers you’ve collected yourself, or randomly generated numbers using the platform’s “Global Number Generator” (generation is free).
- Number format requirement: include the international country code, e.g., 8613800138000 or +8613800138000. Without the country code, the number will be treated as a local number and may not be correctly matched to the platform.
Choose the target platform(s)
- Telegram, WhatsApp, iMessage, RCS, etc. Different platforms offer different check types.
- Beginners are advised to start with Telegram or WhatsApp — these are the most commonly used for overseas marketing.
Decide on the check type
- Just “registration check”? Or do you need “activity (7/15/30 days)”? Do you need “gender identification”?
- The more check types you select, the higher the per‑number cost. Initially, choose only “registration check” to keep costs low while verifying the process.
Ensure your account has sufficient balance
- Number screening is charged per number — no packages, no subscriptions. The minimum top‑up is approximately 50 USDT (TRC20). The system will show an estimated fee before you submit a task; if your balance is insufficient, the task cannot be submitted.
- See real‑time prices in the console.

Beginner Preparation Checklist Tips

① Check number format: It is recommended to unify them as “country code + number” with no spaces or special symbols.
② Number per task: Beginners should start by submitting 1,000–5,000 test numbers, then move to larger batches once familiar (single task max ~1 million numbers).
③ Prioritize using the “Data Deduplication Vault” to avoid re‑screening numbers that have already been checked — this can save you 30%–50% of your balance (detailed below).

Step 1: Register and Log In to the Console

Open your browser and visit the App Console:

If you don’t have an account, click “Register”, enter your email and password to create one.
If you already have an account, simply log in and enter the main workspace.

After logging in, you’ll see a clean left‑hand navigation bar with all core functions clearly laid out.

How to Find the Core Functional Areas in the Console?

The left navigation mainly includes:

Number Generator: Free global number generation
Screening Tasks: Create and manage screening tasks
Task Management: View task details and download results
Data Deduplication Vault: Upload numbers for deduplication to avoid duplicate charges
Recharge: Top up your balance via USDT (TRC20)
Personal Settings: Modify account info, bind Telegram notifications

The two modules beginners will use most often are “Screening Tasks” and “Number Generator”.

How to Link Your Telegram Account to Receive Notifications?

In “Personal Settings”, find the “Telegram Notification” option. Enter your Telegram user ID or click the “Bind” button and follow the prompts — either scan a QR code with Telegram or send a verification code. Once bound, the system will automatically push a message after each screening task is completed, including a summary of results and a download link. This allows you to stay efficient without constantly monitoring the console.

Step 2: Prepare Number Data — Global Number Generation & Custom Import

There are two ways to obtain numbers for screening. Beginners are advised to first use the “Global Number Generator” to generate a batch of test numbers for free, get familiar with the process, and then import their own data.

Use Random Generation to Create Test Numbers (Ideal for Beginners Without Existing Data)

Click “Number Generator” on the left.
Select the target country (supports 240+ countries/regions). For example, if you want to target the Southeast Asian market, choose “Indonesia” or “Thailand”.
Choose the generation method: random generation, generation by number segment, or upload a custom CSV of number segments.
Set the quantity (e.g., 1,000 numbers) and click “Generate”. Generation is completely free and will not deduct any balance.
The generated numbers will automatically enter your “Pending Screening Number Pool”, and you can reference them directly when creating a task later.

Import Your Own Number List (Ideal for Operations Teams with Existing Target Area Data)

If you already have a collected list of customer phone numbers (e.g., from trade shows, e‑commerce orders), you can upload a CSV or TXT file:

Format requirement: one number per line, supporting international formats with or without +.
Maximum rows: approximately 1 million (recommend uploading in batches).
Before uploading, it is strongly recommended to first run the numbers through the “Data Deduplication Vault” to filter out numbers that have already been screened, avoiding duplicate charges.

Step 3: Create a Screening Task — Select Platform, Check Types & Estimate Costs

Click “Screening Tasks” on the left → “New Task”.
Select number source: You can choose numbers from the “Pending Screening Number Pool” (e.g., the ones you just generated) or directly upload your own file.
Select platform: Check Telegram, WhatsApp, iMessage, etc. You can select multiple platforms simultaneously to cross‑platform screen the same batch of numbers.
Select check types: Each platform has different options. For example, under Telegram you can choose:
- tg registration (registration check)
- tg valid (account is usable)
- tg active (you can specify 7/15/30‑day activity window)
- tg gender (profile picture recognition)
- Export tgid
The system will automatically display the estimated deduction amount based on the platform(s) and check types you selected. Confirm that your balance is sufficient, then click “Submit Task”.

Important Reminder

Double‑check the estimated fee against your current balance before submitting. If the balance is insufficient, the task cannot be submitted. Please first recharge USDT (TRC20) to your account — detailed steps can be found on the “Recharge” page.

Step 4: View Task Progress & Export Results

After submitting the task, it enters the system queue. You can see the status of each task on the “Task Management” page (queuing, running, completed). Large tasks may take from a few minutes to several hours, depending on the volume.

Once a task is completed, its status changes to “Completed” and a “Download” button appears on the right. Click to download, then choose CSV or TXT format. Open the result file and you will see fields like:

Number
Platform
Registered (yes/no)
Active days (if registered and active)
Gender (male/female/unknown)
tgid/wsid (if you chose to export them)

You now have a precisely filtered list of valid numbers, ready for friend adding, direct messaging promotions, or community management.

How to Avoid Common Beginner Mistakes? (Charging Pitfalls & Data Contamination)

Mistake 1: Submitting the same number list repeatedly
You run a screening task, then later submit the same numbers again, resulting in duplicate charges. Solution: Before creating a new task, first import the numbers into the “Data Deduplication Vault”. The system will automatically mark numbers that have already been screened and exclude them from new tasks, saving you wasted balance. According to platform data, using deduplication can save 30%–50% of costs.
Mistake 2: Skipping activity screening and directly adding friends
Even if a number has a Telegram account, if that person hasn’t logged in for a year, the success rate of friend adding is extremely low. It is recommended to at least choose “7‑day active” or “15‑day active” screening, keeping only recently active accounts — this doubles your efficiency.
Mistake 3: Submitting a task when your balance is too low
Although the system checks the balance, if you are just a few cents short, the task cannot be submitted and you waste time. It is advisable to top up a certain amount in advance (e.g., 50 USDT) and keep your balance no lower than 1.2 times the estimated fee.

Frequently Asked Questions

Q: How do I view the results after screening is complete?
A: Once the task is completed, go to “Task Management” in the console, find the corresponding task, click the “Download” button, and export a CSV or TXT file. The results include whether the number is registered, activity level, gender, tgid/wsid, etc. If you have bound Telegram notifications, a download link will be automatically pushed when the task finishes.

Q: What is the minimum balance needed for the first screening?
A: Charges are per screened number. The minimum top‑up is approximately 50 USDT (TRC20). For example, with Telegram registration checks, this amount can screen several thousand to tens of thousands of numbers (see real‑time unit prices in the console). We recommend first topping up 50 USDT, testing with a small batch (e.g., 1,000 numbers), and then scaling up once familiar.

Q: Can I screen multiple platforms at the same time?
A: Yes. When creating a task, simply check Telegram, WhatsApp, etc., in the “Select Platform” section. The system will check the same batch of numbers against each platform separately. Different platforms have different check types and unit prices, and the estimated fee will be added up accordingly. After submission, the system processes them in parallel.

Q: Can I directly use the generated numbers for screening?
A: Yes. Numbers generated using the “Global Number Generator” function are automatically placed into the “Pending Screening Number Pool”. When creating a screening task, you can directly select all numbers in this pool. Generation is completely free; you are only charged when the numbers are screened.

Q: Why does my task show “Insufficient balance”?
A: When you submit a task, the system estimates the total cost based on the number of numbers and the check types selected. If your account balance is less than the estimated cost, the task cannot be submitted. Please first recharge via the “Recharge” page using USDT (TRC20). Once the funds arrive, your balance will update automatically, and you can try again.

Start your first screening task now! It only takes four steps: prepare numbers → create a task → wait for completion → export results. Remember to use the “Data Deduplication Vault” to save on costs, and choose the appropriate activity check based on your target — this can multiply your customer acquisition efficiency.
