The number exists, but I cannot receive text messages or make calls. What is the reason? For teams that do overseas registration, international text messages, calling systems, account verification and other services,Determination of failure statusIt is often the key factor that affects the final success rate.

Not all communication failures mean"The number is invalid", and not all failures can reveal the specific reasons from the SMS platform error code. By accessing the global mobile phone number failure status identification service, the source of the problem can be accurately determined and the possibility of failure can be fundamentally eliminated. Digital Planet supports docking with all types of failure status identification interfaces, helping enterprises to filter out unreachable mobile phone numbers in advance and improve the efficiency of communication resource usage.

What are the common classifications of communication failure status?

In the global operator system, communication failures can usually be divided into the following categories:

1.Target device shuts down

The device is currently off or in airplane mode, the operator returns"Unreachable" results, the text message/voice cannot be delivered.

2.SIM card is not activated or suspended

The number exists but the service has not been activated, or it has been temporarily deactivated due to arrears, violations, etc.

3.Virtual number segment or one-time number

likeService account segments such as VoIP, registrar, and Google Voice have short existence times, weak communication capabilities, and are prone to failure.

4.Poor network signal

The current signal of the user equipment is weak, causing voice dialing failure, text message sending and receiving failure, and data delay.

5.The number has been canceled or recycled

The original user has deactivated the number, the number segment is idle or waiting for allocation, and the operator cannot confirm its communication status.

6.Actively intercepted by the target device

Some users set up blocking unfamiliar text messages or voice calls, which is a local policy rejection and is not necessarily a system problem.

These situations may appear on the log as"Failure", but the handling strategies for each failure are different and must be clearly classified.

Why is sending the platform return value alone not enough?

The status returned by many SMS or voice platforms is simple"Failure" only has an error code, and does not indicate whether it is a shutdown, shutdown, or an abnormality in the number segment.

For example:

lerror code30007: Undeliverable

lerror code30120: Unknown user

lerror code30201: The target device is unreachable

If there is no further judgment mechanism, the business system can only process it as"Retry on failure" or "Resend", which has the following consequences:

lConsume channel resources

lIncrease the cost of repeated operations

lReduce number credit score

lInterference with operational data analysis

lcan't really solveThe “why failed” question

By accessing a dedicated failure status identification service, these data blind spots can be supplemented, the reasons for failure can be clarified, and accurate decisions can be made.

What fields can the failure status identification interface return?

A complete failure status detection service should support the following output:

lCurrent communication status (normal/fail)

lFailure type (shutdown/Down/Inactive/VoIP/Recycling, etc.)

lCommunication capability judgment (whether it supports voice/Short message)

lLast active time (if supported)

lIs it recommended to retry sending?

lRisk score (whether there are frequent abnormalities in the failed number segment)

The interface service provided by Digital Planet supports structured return of this information, which facilitates automatic processing and logical judgment by the business system.

Typical scenarios using failure status identification

1. Registration system filters abnormal numbers

Before sending the verification code, determine whether it is a known failed number segment to avoid wasting verification code resources.

2. Call centers avoid dialing failed numbers

Detect number status in batches and mark shutdown, no signal, and recycling numbers in advance to improve outbound call efficiency.

3. Clean the list before marketing SMS batches

Eliminate numbers that have frequently failed or are unreachable in the recent past to improve the overall delivery rate and return rate.

4. Account pool stability monitoring

Detect whether the numbers in the registration number pool have abnormal segments with a high failure rate and implement risk control isolation.

5. Supplementary judgment on user identity verification

Detect whether the number submitted by the user is in an abnormal state and provide auxiliary judgment conditions for the risk control system.

The detection method supports real-time and batch modes

lReal-time detection: suitable for triggering front-end actions such as registration and login to instantly determine the number status

lBatch detection: suitable for large-scale processing scenarios such as database cleaning, list filtering, and pre-outbound call detection

Enterprises can flexibly choose according to business nodes and connect within the system.API calls automatically return status results without interfering with the front-end process.

How to improve the overall communication success rate?

In addition to access failure status identification services, it is also recommended to cooperate with the following strategies:

lSet a failure retry threshold to avoid infinite retransmissions

lEstablish a blacklist of failed number segments to limit reuse

lCombined with the four matching information (place of origin/operator/network type) to make joint judgments

lRemove numbers with a high number of failures from the main channel list

lConduct periodic number pool health checks to keep data clean

Failure is not the end, but it cannot be ignored. A truly efficient team will predict risks before failure occurs and only interact with reachable numbers.

Global mobile phone number communication failure status affects registration, verification, marketing, and call success rates"Invisible variables". If you don't identify it, it will repeatedly bring down your business. The failure status detection service provided by Digital Planet helps you know in advance "which numbers do not need to be touched and which numbers are worth pushing." If we can afford to use resources, we must also be able to save resources. Identifying failures is the first step to start optimization.
