When operating SMS, voice, social registration or customer verification services in the US market, the most common and most difficult question is: Can the mobile phone number in your hand still be used?

Manually verifying each number is slow and inaccurate. Really professional teams choose to access it.U.S. mobile phone number validity checkAPI interfaceto achieve automatic judgment. Platforms like Digital Planet support batch detection, real-time verification and availability identification of local mobile phone numbers in the United States, providing basic guarantees for various business scenarios.

lregisterWhatsApp and other social platform accounts

lMass SMS notification or verification code

lBuild a marketing user pool or account pool

lImport mobile phone numbers for filtering, tagging, and creating portraits

lMake batch calls for outbound follow-up

But if you don’t check whether the mobile phone number is valid first, you will see:

lThe registration failure rate is high and the verification code cannot be sent out.

lLow SMS delivery rate, compromising channel quality

lThe number database contains a large number of empty and fictitious numbers

lThe call system has poor connection rate and costs are wasted

lThe system is slowed down by junk accounts, affecting overall efficiency.

Therefore, the first step is to clear out those invalid, unavailable, and inactive numbers.

2. Whether it is empty or inactive

It can identify those numbers that have been canceled, not enabled, and not registered for communication services, and invalid data can be eliminated in advance.

3. Whether you are online

Determine whether the number is still active and whether it is bound to the operator's network.

4. Is it a VoIP number?

Recognize such asVirtual Internet phone numbers provided by platforms such as TextNow and Bandwidth are used to filter out high-risk segments or commonly used segments by registrars.

For businesses, the process is clear:

1.Select a service platform (such as Digital Planet) to obtainAPI access key

2.Access registration system, SMS service system, and number pool management system

3.Automatically call the interface to detect the status each time a new number is entered.

4.After the interface returns the result, the system handles it according to the rules (retain, reject, mark risk)

5.When uploading a list of numbers in batches, you can also perform cleaning and marking at one time

This process can significantly reduce manual judgment, improve conversion efficiency, and reduce the risk of technical misjudgment.

5. JudgmentSeveral standards for API interface quality

not allThe APIs are all the same, and the following points are key:

lCan the response speed be withinResults returned within 1 second

lIs the supported data update frequency high?

lWhether to overwrite true+Virtual+VoIP full number segment

lCan the accompanying labels be output (whether the number is empty, whether SMS is supported, whether it is a risk segment)

lWhether to support batch detection and automatic elimination functions
