A must-read for newbies: How to obtain valid iMessage numbers in batches? Complete screen number tutorial

Have you ever purchased a batch of mobile phone numbers and imported them into the iMessage mass sending tool with high expectations, only to find that the sending success rate was less than 20%? Most novices will step into the same trap when they first try iMessage promotion: thinking that all mobile phone numbers can send and receive iMessage.

The fact that a number can “open” voice calls doesn’t mean it supports iMessage. To save your push costs, the first step is to batch screen out the real iMessage valid numbers.

This article will start from scratch and help you understand the definition of valid iMessage numbers, manual verification methods, and how to use the screening tool to efficiently obtain valid lists in batches. There is no terminology in the whole process, and it is suitable for novices who want to go overseas.

What is a valid number for iMessage?

iMessage is an instant messaging service provided by Apple that relies on an Apple ID and a network connection. An iMessage valid number refers to a mobile phone number that has registered and activated the iMessage service and can theoretically send and receive iMessage messages normally.

Correspondingly, it is a number that only supports ordinary text messages (SMS/MMS). If both the sender and the receiver are in the iMessage environment, the message will be displayed as a blue bubble; if the receiver has not subscribed to iMessage, the message will be downgraded to an ordinary text message with a green bubble.

The difference between a valid iMessage number and an ordinary mobile phone number

To be more intuitive, let’s look at a set of comparisons first:

Type	Dependencies	Can iMessage be sent	Message bubble color	Is there any SMS fee required?
iMessage valid number	Apple ID + network	Yes	Blue	No (data traffic)
Ordinary mobile phone number (iMessage is not activated)	Operator network	Cannot	Green	Yes (charged per item)
iMessage Invalid Number	No Apple ID associated	Can’t	Green	Yes (per message)

Simple summary: A number can make calls ≠ It can receive iMessages. There is no filtered number list, and a large number of them may just be ordinary mobile phone numbers. After sending, high SMS fees will be incurred, and the user receives only ordinary text messages, which results in a very poor experience.

Blue number vs green number: the most confusing concept for newbies

Many novices are confused by the terms “blue number” and “green number”.

• Blue Number (blue bubble): Both parties to the conversation are in the iMessage environment, using Apple servers, and does not consume the operator’s SMS plan. This is the valid number you want for iMessage.
• Green Number (green bubble): The sender is an iPhone, the receiver has not subscribed to iMessage, and the message will be sent as a normal text message. If the recipient is an Android phone, the blue number will never be displayed.

So, filtering iMessage for valid numbers = finding those numbers that light up “blue.” This is the list that is truly worth pushing.

Why is it necessary to filter valid iMessage numbers when promoting?

If you send directly to groups without filtering, you may encounter three big pitfalls:

1. Costs are out of control: Very few of the unfiltered numbers are truly valid for iMessage. Those invalid numbers will be converted to SMS every time they are sent, and billed on a per-message basis. To send 10,000 messages, the cost may be several times higher than expected.
2. Invalid Reach: Even if you are using the iMessage mass sending tool, if the recipient has not activated it, the message still cannot be delivered in the form of iMessage, and the conversion rate is almost zero.
3. Reduced efficiency: If you push to a large number of invalid numbers, you will repeatedly receive “not delivered” feedback, occupying tool resources and reducing the execution efficiency of the entire process.

**To sum it up in one sentence: spend 10% of your efforts on screening, and save 70% of wasted money. **

How do novices manually determine whether a number supports iMessage (batch scenarios are not recommended)

If you only have a single-digit number and want to double-check it, you can use this manual method:

1. Open the Messages app on your iPhone.
2. Create a new message and enter the other party’s number (must include an international area code, such as mainland China plus +86).
3. After entering some text, observe the send button icon on the right side of the input box:
   • If it’s a blue arrow → Send an iMessage to that number.
   • If it is a green arrow → the number is not subscribed to iMessage, the message will be sent as SMS.

The disadvantage is obvious: input one by one. If you have a thousand numbers to be tested, you have to do it manually a thousand times. It is time-consuming and error-prone. It is only suitable for checking a very small number of numbers (such as verifying one or two numbers). In batch scenarios, automated screening tools must be used.

How do newbies filter valid iMessage numbers in batches? (step-by-step tutorial)

The following takes the KK-DATA platform as an example to demonstrate a complete process. From preparing numbers to exporting results, every step is replicable.

Step 1: Prepare the list of numbers to be tested

You need a file containing a mobile phone number. The format requirements are as follows:

• File Format: CSV or TXT.
• Number Format: One number per line, must include the international area code (such as +8613800138000). If the area code is missing or the number is in the wrong format, the detection results may all be “Not activated”.
• Quantity: It is recommended not to exceed 1 million items at a time. If the number is large, it can be submitted in batches.

**Where does the number come from? **

• You already have your own customer list and platform export data.
• Use KK-DATA’s built-in “Global Number Generation” module to generate numbers in specified country/region code segments for free (full coverage of 240+ countries). Submit the iMessage filtering task after generation.
• Collected from public sources (pay attention to compliance and avoid misuse of personal information).

It is recommended to organize the files first to ensure that the area code is correct. For example, the number format for mainland China is +8613800138000 and the number format for the United States is +12025551234.

Step 2: Submit iMessage screening task in the console

1. Log in to KK-DATA Console.
2. Select “Filter Number” → “New Task” from the left menu.
3. Find “iMessage Valid Number Detection” in the platform selection (note that this is not “iOS Device Detection”, they are different).
4. Upload the number file (CSV/TXT) you prepared.
5. The system will automatically parse the number of numbers in the file and display the estimated cost on the interface. Fees are billed on a per-item basis. Please refer to the real-time price of the console for the specific unit price (do not believe in online quotations).
6. Submit the task after confirming that it is correct.

Step 3: Wait for completion and export the results

After submitting you will be returned to the task list. After the task is completed, the system will send a notification through the Telegram account you have bound to your account.

On the task details page, you can choose the export format (CSV or TXT). The exported file will contain fields similar to the following:

Number	iMessage activation status	Notes
+8613800138001	Activated	Valid
+8613800138002	Not activated	Invalid
+8613800138003	Activated	Valid
…	…	…

You only need to filter out the numbers with a status of “activated” (or “valid”) for subsequent promotion.

4 common pitfalls when filtering valid iMessage numbers

Let me help you list the most common mistakes that novices make, and try to avoid them:

1. The number is missing the area code or the area code format is wrong If there is no Chinese number with +86, or the area code is written incorrectly (for example, 0086 instead of +86), the system may not be able to associate with the correct detection resource, causing all numbers to be determined to be unavailable.

2. Repeated detection of the same number Submitting the same batch of numbers repeatedly for different tasks is equivalent to spending money to test the same batch of people twice. KK-DATA has a built-in data deduplication warehouse. It is recommended to enable the deduplication function to avoid waste.

3. Confusing iMessage valid numbers and iOS device detection iMessage detection verifies the service activation status, which does not mean that the number is currently being used by an Apple device. The corresponding detection function for the latter is “iOS device detection”. The two dimensions are different and can be used in combination.

4. The number itself comes from high-risk or illegal channels The number, although valid, may be a bot or abandoned. It is recommended to cooperate with activity detection (such as Telegram/WhatsApp activity detection) for further filtering.

How to choose the right iMessage filtering tool?

When choosing a batch screening tool, focus on the following points:

• Support international numbers: Many tools only support numbers in mainland China or certain specific countries, and cannot meet the global overseas needs.
• Flexible billing: billing by item vs fixed package. Overseas teams usually have unstable number numbers, and pay-as-you-go billing (no monthly/annual subscription) is more flexible.
• DATA SECURITY: Does the tool save your number list? Clarify data privacy protection policy.
• Export format: Supports common formats (CSV, TXT) and has clear status marks.
• Technical Support: Is there online customer service or documentation guide.

Based on these standards, KK-DATA provides iMessage valid number detection, supports 240+ country numbers, billed per message, no subscription required. These features make it more suitable for novices going overseas and small and medium-sized teams.

FAQ

Q: What is the difference between iMessage valid number detection and iOS device detection?

Answer: iMessage valid number detection verifies whether the number has registered for iMessage service (can send and receive iMessage). iOS device detection determines whether the number is currently associated with an Apple device (such as iPhone, iPad). The two detection dimensions are different and can be used in combination. For example, you first test valid iMessage numbers, and then filter iOS device users from the valid numbers.

Question: Does the detected valid iMessage number must be an Apple mobile phone user?

Answer: Not necessarily. A valid iMessage number means that the number has been bound to an Apple ID and iMessage is enabled. The user may log in to the same Apple ID using an iPhone, iPad, Mac, etc. And even if the device is turned off or offline, the activation status is still “valid” (it is just temporarily undeliverable).

Question: Why are all the test results of the numbers I submitted showing “not activated”?

Answer: There are four common reasons:

• The number is missing an international area code, or the area code format is incorrect (e.g. + is missing).
• The number itself is indeed not iMessage enabled (e.g. from an Android user).
• A large number of detections of the same number in a short period of time are restricted by the system (it is recommended to try again in batches).
• The number comes from a small operator or a virtual operator and may not be supported by iMessage.
  It is recommended to test in small batches (for example, 100 items) first, and then operate in batches after confirming that the format is correct.

Question: Can the detected valid number be used for iMessage group sending?

Answer: Yes. But there are two caveats:

• The detection result only means that the number has opened iMessage in history, and does not guarantee that the other party’s device is online when sending.
• Large-scale group sending of iMessages may involve risks of abuse. It is recommended to comply with the platform terms of use and local laws and regulations. If you are worried that the device is not online, you can further filter with activity detection.
