When you get a U.S. mobile phone number, your first reaction may be: Which state is it from? Which operator are you using? Yes or noT-Mobile, Verizon, or a VoIP virtual account? If you have to deal with a large number of numbers every day, this judgment cannot be made with the naked eye. Instead, you have to rely on a professional API interface to automatically identify the location and operator information.

Especially when doing SMS delivery, account registration screening, social binding, voice contact and other services, knowing in advance which operator and state the mobile phone number belongs to can greatly improve the hit rate and system stability. Many cross-border business teams have integrated this type of detection services into their processes. Platforms like Digital Planet provide interface services specifically designed to identify the location and operator of U.S. mobile phone numbers.

1. Why is the location and operator information important?

The United States is a typical country with diversified number resources. The number segments of the same operator may span multiple states, and the SMS and voice policies of different operators are also different. If you don’t know the background information of the number, these problems are prone to occur:

lDeliver toOn VoIP numbers, the message delivery rate is low;

lWhen dialing from the number broadcasting platform to a non-mobile terminal, the connection rate is poor;

lMarketing reaches touch typing and there is no geographical stratification strategy;

lSocial platform registration failed because a high-risk control section was used;

lThe quality of the verification number is poor, causing the account pool to be unstable.

Knowing the location of the number and the identity of the operator can help you make classification, filtering, and policy selection at the data entrance.

two,What information can the API interface return?

a practical place to belong+ Operator identification API interface can usually return these core fields:

lOperator name:likeAT&T, Verizon, T-Mobile, etc.

lState/area code:For exampleCalifornia, Texas, New York, etc.

lWhether it is a virtual operator (MVNO):likeGoogle Fi, Cricket Wireless

lCommunication type:Mobile (mobile), Landline (fixed line), VoIP (network)

lIs it an active paragraph?: Used for further strategic judgment

The combination of these fields can help you make basic judgments: whether this number can be sent, whether it is worth sending, and what channel to use.

3. What are the typical usage scenarios?

1.SMS gateway routing

The SMS platform can determine in advance which channel should be selected based on the operator affiliation, thereby improving the delivery rate and reducing costs.

2.WhatsApp registration control

Identify high-risk control segments or virtual operator number segments to avoid wasting registration resources and triggering frequent failures.

3.Call system policy assignment

According to the location of the number, localized call periods or local scripts can be arranged to improve the call completion rate and response willingness.

4.Data cleaning and label management

Conduct preliminary screening and labeling of customer information before importing it to facilitate subsequent private domain management and marketing strategy implementation.

5.User source verification

Some businesses require that the mobile phone number must be local and actually in use.The API can quickly determine whether conditions are met.

4. Enterprise access to this type ofHow to make API interface generally?

Enterprises or development teams often integrate such interfaces into existingCRM system, registration guidance system, delivery system, anti-cheating strategy. The basic process is:

lGet number data (user input, import, collection)

lreal time callThe API interface returns the location and operator fields

lStore results in database or temporary cache

lTrigger the corresponding policy based on the return value (allow/deny/tagging/filtering)

Digital Planet Platform SupportAPI key docking, short development cycle, standard calling method, and the basic process can be run through in a few minutes.

5. Use this type ofWhat issues should we pay attention to when using APIs?

1.coverage completeness

It is not only important to identify large operators such asVerizon), and also need to be able to identify a large number of small operators, MVNOs, and VoIP platforms.

2.Data update frequency

Operator data changes frequently,The API interface must regularly synchronize the authoritative number resource library to ensure accuracy.

3.Response speed and concurrency

For registration systems or real-time service applications, the interface speed must be fast and the concurrent processing capability must be strong, and the overall business rhythm must not be slowed down.

4.Batch processing capability

In addition to the real-time interface, it should also support one-time import of batch numbers for cleaning operations, which is suitable for big data processing scenarios.

5.Risk segment marking capabilities

Experienced platforms will mark some number segments that are frequently reported and have abnormally high fluctuations to facilitate your avoidance strategies.

Identify the location and operator information of the mobile phone number, not oneThe “icing on the cake” function is your basic ability to enter the US market and do high-quality number operations. Choosing a stable, comprehensive, and fast-responding API interface can help you control the number quality from the source, so that every text message, every call, and every account registration is used on the right number.

If you have a batch of numbers in your hand that you are not sure whether they can be used, and want to know who they belong to, which state they are in, and whether they are worth accessing, Digital Planet’s detection interface is ready to answer all your questions.
