From Global Number Generation to Filtering WA Valid Numbers: A Complete Pipeline Operation Guide

In overseas marketing and private messaging campaigns, obtaining high-quality WhatsApp (WA) valid numbers is the first and most critical step. Many teams are accustomed to manually collecting numbers from communities, web pages, or Excel files, but this method is not only inefficient but also yields a large number of invalid or unregistered WA numbers, leading to wasted bulk messaging costs. This article introduces a more efficient pipeline: first build a number pool using the Global Number Generation feature, then automatically filter truly usable numbers through WA Validity Check, forming a closed loop of “Generate → Filter → Export”. You can perform all operations directly in the KK-DATA Console without switching between multiple tools.

Why “Generate Numbers” Before “Filter for WA Validity”? — What Problems Does This Process Solve?

Pain Points of Traditional Methods

Limited manual collection volume: Numbers scraped from the web or manually compiled are usually only a few hundred to a few thousand, far from meeting large-scale promotion needs.
Uncontrollable number quality: Many numbers are landlines, not enabled for IM services, or even garbled characters, and cannot be verified before use.
Wasted cost on invalid/unregistered numbers: Directly importing numbers for bulk messaging results in high failure rates, consuming API quotas and harming reputation.

Core Benefits of the Pipeline Solution

Adopting the combined “Generate + Check” approach solves all the above problems:

On-demand number generation: Supports 240+ countries/regions, allowing random generation, generation by number ranges, or importing custom ranges. The generation process is completely free.
Free generation, pay only for checks: Number generation does not deduct balance. Charges only apply after submitting a WA validity check task, based on the actual number of numbers checked. Pay as you go.
Direct screening after generation forms a closed loop: Within the same platform, from number generation to WA validity check and result export, everything is seamless—no data conversion or cross-platform transfer needed.

Step 1: Build a Number Pool with the Global Number Generation Feature

Operation path: Log in to the KK-DATA Console → Enter the “Number Generation” module.

Select Country/Region: The dropdown menu supports 240+ countries. For example, if you are targeting the Middle Eastern market, you can select Saudi Arabia, UAE, Egypt, etc.
Choose Generation Method:
- Random Generation: The system automatically draws numbers randomly from legal number ranges of that country, suitable for quickly obtaining a large sample.
- Number Range Generation: If you know a specific number range in the target country (e.g., mobile numbers starting with 05X), you can manually input the prefix to generate consecutive numbers under that range.
- CSV Import Custom Ranges: If you already have your own whitelist of numbers, you can upload a CSV file; the system will parse it and generate the corresponding numbers.
Set Quantity: Enter the number of numbers you need to generate, e.g., 50,000. There is no limit on generation quantity, but it is recommended to test with a small batch first.
Export Format: Supports CSV and TXT. After export, you will have a clean number list.

After generation, you can view and manage the generated numbers in the “Number Warehouse”. At this stage, these numbers have not undergone any platform verification—they are “raw numbers”.

Step 2: Import Generated Numbers into a WA Validity Check Task

Once you have the number list, go to the “Number Screening” module to create a check task.

Create a New Task: Click “New Task” and select the check type as “WhatsApp Validity Check”.
Import Numbers: Supports uploading CSV/TXT files or pasting numbers directly (one per line). The system will automatically deduplicate and validate formats.
Preview Quantity: Confirm the total number of imported numbers; the estimated deduction will be displayed at once (sufficient balance is required to submit).

Precautions for Number Import

Single Task Limit: Each check task supports up to approximately 1 million numbers. If the number exceeds 1 million, split it into multiple tasks.
Deduplicate Before Checking: It is strongly recommended to use the “Data Dedup Repository” function to cross-check the current numbers against previously checked numbers, removing duplicates to avoid repeated charges.
Small Batch Testing: If you are using numbers from a certain country for the first time, generate 1,000–2,000 numbers first, submit a check to see the validity rate, and then decide whether to scale up.

Confirm Check Type and Unit Price

Before submitting the task, the system will display:

Check Type: WA Validity
Estimated Fee = Number Count × WA Validity Check Unit Price (check the console for real-time pricing)
Whether the current balance is sufficient

After confirming, submit the task, which will enter a queue for execution.

Tip: Deduplicate before checking to save costs

Before submitting a check, it is recommended to use the Data Dedup Repository function to filter out numbers that have already been checked, avoiding duplicate charges. For details, see the Documentation.

Step 3: Monitor Task Progress and Receive Results Notifications

After submitting the task, you can view its status in the “Task List” of the console:

Queued: Waiting for the check engine to process.
In Progress: Being checked one by one.
Completed: Check finished, results ready for download.

To get results promptly, it is recommended to bind Telegram notifications: go to “Settings → Notifications”, enter your Telegram Bot Token, or associate via the platform’s linked @kkdata_bot. When the task completes, a result link will be automatically pushed to you.

Step 4: Export WA Valid Numbers and Apply Them

After the task is completed, click “Download Results” and select the desired export format (CSV/TXT). The result file usually marks the status of each row: WA Valid, WA Invalid, Unknown, etc. You only need to extract the numbers marked as “WA Valid”.

These valid numbers can be directly used for:

WhatsApp bulk messaging campaigns
Importing into CRM systems for follow-up
As seed users for retargeting

Best Practice: Small Batch Seed Testing

Start by generating 1,000–2,000 numbers to verify the quality of numbers in your target country. After confirming the WA validity rate, proceed with large-scale generation to effectively control your budget.

Tool Switching	Multiple platforms/scripts	All operations closed-loop within KK-DATA Console

Summary: Through the “Global Number Generation → WA Validity Check” pipeline, you can obtain a high net-worth pool of reachable WhatsApp users with minimal trial costs. This process has been verified by many overseas marketing teams, significantly improving the return rate of bulk messaging.

Frequently Asked Questions

Q: Is generating WA numbers free? How is the check charged?
A: Yes, the global number generation feature is completely free and does not deduct from your balance. Charges only apply after you submit a WA validity check task and it is completed, based on the actual number of numbers checked. For specific unit prices, check the real-time pricing in the console.

Q: What is the maximum number of numbers I can generate and check at one time?
A: There is no limit on generation quantity, but each single screening task supports up to approximately 1 million numbers. If the number exceeds 1 million, it is recommended to split into multiple tasks and submit in batches.

Q: Can the same batch of numbers be checked for both WA and Telegram simultaneously?
A: Yes. You can first generate a number pool, then copy the numbers and submit them separately to WA validity check and Telegram check tasks. However, each task must be submitted and billed separately; ensure your balance is sufficient.

Q: How long does it take to check one WA number?
A: Actual time depends on the length of the task queue and the total number of numbers. Small batches (a few hundred) typically finish within minutes; large batches (tens of thousands) may take several hours. You will be notified when the task is completed to download results.

Q: How reliable are the “WA valid” numbers from the check?
A: KK-DATA uses multiple rounds of protocol verification to determine whether a number is a registered WhatsApp user. Accuracy is maintained at a reasonable level, but extreme network conditions or a small number of numbers may experience delays. It is recommended to export and conduct small-scale testing before formal use.

If you need to quickly build your own WhatsApp marketing number pool, log in to the KK-DATA Console and experience the complete pipeline of “generate then screen WA valid numbers”. For first-time use, start with a small batch for verification. If you have any questions, refer to the Documentation or contact Telegram support @kkdata_cc.
