Why Do You Need to Export US WA Numbers?

Teams targeting the US market typically need to batch export numbers in the following scenarios:

• CRM remarketing: Import verified valid WA numbers into HubSpot, Salesforce, etc. for automated follow-ups.
• Batch group joining or direct messaging: Use the number list for Telegram/WhatsApp group invitations or one-to-one message outreach.
• Data cleaning: Filter active numbers still registered on WhatsApp from existing historical numbers, removing invalid data.
• A/B testing: Segment numbers by gender, activity level, etc., and export different groups for performance comparison.

Regardless of the scenario, the export format determines the efficiency of the next step. Choosing the wrong format may cause CRM recognition failure, truncated numbers, or duplicate imports that waste budget.

Common Export Formats for US WA Numbers: CSV vs TXT

CSV Format Details and CRM Compatibility

CSV (Comma Separated Values) is the standard format for structured data, containing a header row of fields, with each column having a clear meaning. When exporting US WA numbers, a typical CSV field example looks like this:

Number,Country Code,Status,wsid,Check Time
+14155551234,US,Valid,1gX7...,2025-03-15 10:30
+14155559876,US,Invalid,,2025-03-15 10:30

Advantages:

• CRMs (e.g., HubSpot, Salesforce, Zoho) can directly recognize column names and automatically map them to phone fields.
• You can simultaneously export wsid (WhatsApp ID), detection status, country code, and other auxiliary information for later analysis.
• Supports secondary editing, sorting, and deduplication in Excel or Google Sheets.

Considerations:

• Use English or standard field names (e.g., phone, status) to avoid CRM non-recognition of Chinese column names.
• The number format should always include the international prefix +1; some CRM import configurations require the + sign.

TXT Format Use Cases and Limitations

TXT format contains one pure number per line, without any extra fields:

+14155551234
+14155559876
+14155557777

Use Cases:

• Quick copy into Telegram/WhatsApp group adding tools (many tools only accept plain text lists).
• Temporary lists that do not require structured storage.
• Scripted batch calls (e.g., API reading line by line).

Limitations:

• Cannot include metadata like status or wsid, making it impossible to tell if a number is valid.
• Requires manual processing when importing into CRM; typically you would import a CSV first and then split it, adding extra steps.
• Easy to mix in invalid or unregistered numbers, cluttering the CRM with useless data.

If your ultimate goal is to import numbers into a CRM for long-term management, CSV is strongly recommended. TXT is only suitable for one-off, low-value operations.

How to Export US WA Numbers from KK-DATA (Step-by-Step Guide)

KK-DATA provides an integrated pipeline of “Generate → Filter → Export”. The following steps cover building a US WA number list from scratch.

Step 1: Prepare the US Numbers to Be Filtered

There are two ways to obtain US numbers:

• Method A: Use the Global Number Generation Module
  In the Console, select “Global Number Generation”, set the country to United States (+1), and either generate randomly or by number range. This feature is free, and the results are automatically saved to the task list.

• Method B: Upload an Existing Number List
  If your team already has US mobile numbers (e.g., collected from trade shows or historical orders), upload the CSV or TXT file directly to a screening task. KK-DATA supports up to approximately 1 million entries per batch.

Step 2: Configure the WhatsApp Screening Task

1. In the console, create a new task and select “WhatsApp Detection”.
2. Choose the detection type as “WA Status Check” (i.e., detect whether the number is registered on WhatsApp).
3. Check the “Export wsid” option if you need the wsid later for API calls or re-validation.
4. Before submitting the task, the system will display an estimated cost (see real-time pricing in the console). Confirm sufficient balance and submit.

After submission, the system runs asynchronously. You can be notified via Telegram (must be bound in advance) or check real-time progress in the console.

Step 3: Choose the Export Format and Download the Results

After the task is completed, click the “Export” button on the results page and select the format:

• CSV format: Contains all fields (number, country, status, wsid, check time).
• TXT format: Contains only valid numbers (one per line).

The downloaded file can be used directly for the next step.

Notes on Importing Exported Numbers into CRM

Field Mapping: Ensure CRM Recognizes Numbers

Most CRMs provide a “field mapping” step when importing CSV. You need to map the “number” column from your CSV to the “phone” or “mobile” field in the CRM. Key points:

• Keep the country code +1 intact; do not drop the prefix. Some CRMs require pure digits (e.g., 14155551234), in which case you can remove the + but keep the country code.
• If your CSV includes a “status” column, you can map it to a custom field (e.g., “Number Validity”) for later filtering by status.

Deduplication: Avoid Duplicate Imports That Waste Budget

Duplicate numbers not only waste CRM storage quotas but can also lead to account blocks in subsequent marketing. Recommended practices:

• Before exporting, use KK-DATA’s data deduplication repository feature to deduplicate numbers across tasks, avoiding repeated detection and export.
• When importing into CRM, enable the CRM’s built-in “deduplicate by phone number” feature (e.g., HubSpot’s “duplicate handling” option).
• If the exported file is large, consider deduplicating based on the number column in Excel or Python before import.

Batch Import Limits and File Splitting Strategy

Most CRMs have row limits per import:

CRM Platform	Approximate Max Rows per CSV Import
HubSpot	10,000 (Free) / 50,000 (Pro)
Salesforce	50,000 (Data Loader)
Zoho CRM	10,000 (Standard)

If your exported file exceeds these limits, split it into multiple smaller files. For example, divide 100,000 records into two 50,000-row CSVs and process them in batches.

Why Should You Screen Numbers Before Exporting?

Using raw number lists (e.g., unverified generated lists or stale data) for export introduces two main issues:

1. High proportion of invalid numbers: Numbers that have not been tested for WhatsApp registration may be 30–60% not registered on WhatsApp at all. Importing these into CRM leaves fields empty and wastes analytical effort.
2. Wasted marketing budget: If you plan WhatsApp direct message campaigns, invalid numbers will increase failure rates and may even cause your account to be flagged as spam.

Recommended approach: Before exporting, use KK-DATA’s “WA Status Check” function to filter out only valid numbers (status “Valid”), then export CSV. This ensures the exported file contains only truly usable numbers, making it more efficient for CRM and subsequent marketing.

Frequently Asked Questions (FAQ)

Q: Which format, CSV or TXT, is better for importing US WA numbers into a CRM?
A: CSV is recommended because it contains field headers (e.g., number, status, wsid), allowing the CRM to directly recognize column mappings. TXT contains only numbers and requires extra processing.

Q: What fields are included in the exported CSV file?
A: Typically: phone number, country code, detection status (valid/invalid), wsid (WhatsApp ID), detection time, etc. Specific fields depend on the platform’s export page.

Q: Can I export only “valid” US WA numbers?
A: Yes. After the screening task is complete in KK-DATA, set the result filter to “Valid” and then export to obtain a file containing only usable numbers.

Q: What is the maximum number of US WA numbers I can export at once?
A: Depends on the number of inputs in the screening task; a single task can handle up to approximately 1 million records. When exporting, you can download in batches; there is no hard limit on rows per file, but it is recommended to keep CSV rows within 50,000 for easier CRM import.

Q: What should I do if after importing to CRM I get a number format error?
A: Check if the numbers in your CSV include the international prefix +1 and remove spaces, hyphens, etc. It is recommended to use an option that keeps only digits and the plus sign (if supported by the platform) before exporting, or clean the data using Excel formulas after export.
