Complete guide to exporting iOS blue number detection results: How to export iOS blue number data in batches

Q: What should I do if the exported file has garbled characters or missing fields?

Cause: In most cases, the Excel default encoding (GBK) does not match the UTF-8 encoding of the CSV file. Solution: Open CSV with Notepad → Save as → Select UTF-8 encoding → Open with Excel. Or manually set the encoding in the export pop-up window (if supported by the platform). If the exported file is garbled in Excel, please import using UTF-8 encoding or choose Notepad to open and save as UTF-8 CSV.

Q: What to do if the amount of exported data is too large?

KK-DATA supports up to about 1 million number detection in a single task. If the original list exceeds one million, it is recommended to submit it in batches. When exporting, you can also use the Data Deduplication Warehouse function to merge multi-task results and remove duplication to avoid repeated detection and export redundancy of the same number.

In overseas marketing and iMessage mass sending scenarios, iOS blue number (that is, the device number that iMessage can reach) is the core data that many teams are eager to obtain. However, how to export these data efficiently and standardizedly after detection often becomes the bottleneck from “data” to “marketing actions”. This article will start from the definition of iOS blue number, gradually dismantle the entire process of detection, export, and application on the KK-DATA platform, and share best practices for improving export efficiency and data quality.

What is an iOS blue account? How is it different from a valid number for iMessage?

iOS Blue Number is not an official term. In industry practice, it usually refers to an Apple device number that can be reached through the iMessage protocol, that is, the number has registered for the iMessage service and the device is online or can receive push notifications. The related concept is iMessage valid number, which often covers a wider range of detection results: including blue number (iMessage is available), green bubble (ordinary text messages can be sent) and other statuses.

In actual screening scenarios, KK-DATA’s iOS blue number detection will return fields such as “Is it an iOS blue number” (yes/no) and “iMessage availability”, helping users directly target targets who can send messages for free through iMessage. However, iMessage valid number detection may also mark “SMS deliverable” as valid. There is a difference in marketing accuracy between the two - ios blue number is a higher value subset.

KK-DATA How to detect and export iOS blue number?

The following is based on the actual operation process of KK-DATA Console (available after logging in).

Submit iOS blue number detection task

Prepare number list: Supports uploading CSV, TXT files, or manually pasting numbers (one per line). The number does not need to be in a unified format, the system will automatically clean it.
Select detection type: On the task creation page, select iOS Blue Number Detection (some versions display “iOS Blue Number/iMessage Valid”).
Submission and Preview Fee: The page will estimate the balance that will be consumed by this test (billing per item, see [Billing Page] (https://kkdata.cc/billing/) for details). Submit the task after confirmation.

hint

iOS blue number detection is a one-time deduction, which will be deducted from the balance after the task is completed; there is no additional charge for exporting the results. The unit price is based on the real-time price of the console. For details, please see Billing Instructions.

View test results and export options

After the task is completed, you can view the detection status of each number one by one on the Task Details Page, including:

Whether it is an iOS blue number
iMessage availability (online/offline/unreachable)
Device type (some fields)
Detect timestamp

Click the “Export” button to pop up the format selection box:

CSV: Retains all structured fields, suitable for subsequent processing with Excel or database.
TXT: Only the number list is retained (can be customized to include status tags), suitable for direct import into group sending tools.

Export field description (what data is included)

The common fields of the exported CSV file are as follows (subject to the actual export by the console):

Field name	Meaning	Example
phone	original number	+8613800138000
is_blue	Whether it is an iOS blue number	true
imessage_status	iMessage availability	active
detected_at	Detection completion time	2025-03-20 14:30:00

Tip: If the export file fields are missing or in an abnormal order, please refer to the column names on the task details page of the console and reselect the export format.

In what scenarios can the iOS blue number export results be used?

iMessage Bulk Marketing: Import the exported TXT or CSV (only mobile phone numbers) into the mass messaging tool to target blue account users.
Empty account filtering and user cleaning: Combined with other filtering results (such as Telegram, WhatsApp detection), retain high-value multi-platform active users.
User portrait supplement: The user device type can be inferred through the iOS blue number status to assist in formulating device targeting strategies.
Competitive product monitoring and industry research: Verify the iMessage activation rate of specific groups of people in batches and evaluate market preferences.

Frequently asked questions and precautions when exporting

What should I do if the exported file has garbled characters or missing fields?

Cause: In most cases, the Excel default encoding (GBK) does not match the UTF-8 encoding of the CSV file.
Solution:

Open CSV with Notepad → Save as → Select UTF-8 encoding → Open with Excel.
Or manually set the encoding in the export pop-up window (if supported by the platform).

Notice

If the exported file is garbled in Excel, please import using UTF-8 encoding or choose Notepad to open and save as UTF-8 CSV.

What to do if the amount of exported data is too large?

KK-DATA supports up to about 1 million number detection in a single task. If the original list exceeds one million, it is recommended to submit it in batches. When exporting, you can also use the Data Deduplication Warehouse function to merge multi-task results and remove duplication to avoid repeated detection and export redundancy of the same number.

How to judge the quality of the exported iOS blue number?

Detection Status Field: Prioritize filtering for numbers with is_blue=true and imessage_status=active for which iMessage service is currently active.
Detection time: The number status will change over time (for example, the user logs out of iMessage). It is recommended to re-detect before sending in groups (the platform supports re-submitting the exported blue number list for detection).
Activity Assist: Some detection types will return the “number of recent active days”, which can be used in combination to further improve the message arrival rate.

How to use iOS blue number detection with other platform screening numbers?

Acquiring customers overseas often requires multi-platform coverage. For example, you want to send both Telegram messages and iMessages to the same number:

First use Telegram Screener to check whether the number is subscribed to Telegram and is active.
Conduct iOS blue number detection on the same batch of numbers at the same time or subsequently.
Merge the two export results by mobile phone number (such as VLOOKUP), and filter out users with “Telegram active + iOS blue number” to achieve low-cost dual-channel reach.

Similarly, it can also be combined with WhatsApp screen number and Line screen number to build a multi-dimensional user portrait.

FAQ
