If you want to know which operator a US mobile phone number uses, it’s too slow to check each one on the web.The Excel matching database is also long out of date. Especially when you have to deal with thousands of numbers every day,Stable, fast, real-time responseAPI interfaceThat's the easiest way.

In practical application scenarios, operator identification of Digital PlanetThe API is designed for this need and supportsReturn in real timeThe carrier information of U.S. mobile phone numbers is suitable for many aspects such as registration pool construction, SMS delivery, voice screening, and customer screening.

Why must it be used"Live" API, not legacy database?

The location of the number and the operator information will change, especially in the US market, when users change cards, change operators, and mergers and reorganizations between operators (such asSprint merged into T-Mobile) are common.

If you are using static data:

lQuery results may have expired long ago

lThe virtual operator number segment cannot be updated in time

lNew segments cannot be covered

lThe risk number cannot be marked immediately

lEven if the number is recycled and reused, it cannot be identified

Real-time queryThe advantage of API is that it can be retrieved immediately without delay or misjudgment.

Stable carrier identificationWhat capabilities should the API have?

First, it must be able to handle high concurrent calls. When you do registration detection, SMS filtering, and account pool cleaning, you may process tens of thousands of data at one time, and the interface must be stable and uninterrupted.

Second, the response speed cannot be delayed. Registration verification services have extremely high response time requirements. If the interface returns a few seconds late, it may lead to registration failure or user loss.

Third, the recognition accuracy is high. Can it be accurately identified?AT&T or T-Mobile, whether it is an MVNO, whether it is VoIP, and whether it supports SMS/voice are the fundamental criteria for judging whether this API is worthy of long-term use.

Fourth, it can operate stably for a long time. a lot ofThe API worked fine in the early days, but data updates were slow or the service was not maintained, and errors soon began to appear, especially in markets like the United States, where updates are frequent.

In what scenarios must a stable real-time interface be used?

1.WhatsApp account batch registration

Identify number segments that do not support registration or block high-volume segments to avoid failure costs in advance.

2.Send SMS verification code

Distribute SMS routing in a refined manner to avoidVoIP and channel restriction number segment.

3.Mobile phone number identification on registration page

Intercept virtual card segments or simulator numbers in real time to improve data quality.

4.User screening before marketing launch

Perform operator identification and cleaning on the customer list to decide whether to contact them.

5.Voice robot dial test filtering

Avoid number segments with low connection rates to optimize outbound call costs and user experience.

Why is stability more important than functionality?

API functions are similar, but what really affects the user experience is the interface.stress toleranceandstability:

lDoes it occur frequently?429 limit

lIs there request queuing or timeout?

lWhether the interface frequently changes fields and returns the structure

lWhether to support exception handling and fast retry mechanism

lWhether it has disaster recovery capabilities
