US virtual number and physical card screening techniques: How to stably build a private domain pool

In the process of global social network account registration, SMS service, and customer private domain pool construction,"Whether the number is authentic, stable, and can be used for a long time" is the prerequisite for the success of all businesses. In the United States, the huge operator system and the wide distribution of virtual operators have made the mixing of virtual numbers into the data pool a high-frequency hidden danger, leading to account registration failures, SMS delivery failures, customer churn, frequent risk control and other problems.

This article will systematically analyze how to complete theVirtual number and physical card screening tasks for U.S. mobile phone numbers, and introduces how to achieve efficient, automatic, and structured processing processes through the Digital Planet platform.

The proliferation of virtual numbers has become the biggest risk to the stability of number usage

In the US market, due toVoIP services have matured, and a large number of "free number" or "temporary number" services provided by virtual operators have emerged. Typical representatives include:

lGoogle Voice: Generated through Google account binding, can make and receive calls, but is often used for receiving codes and batch registration.

lTextNow,TextFree:Supports SMS function, but is easily recognized by the platform as a receiving number

lBurner/2ndLine: One-time or short-term use, extremely short life cycle

lUltra Mobile,Mint Mobile:MVNO mode, although it is a SIM card, is not as stable as traditional operators

Most of these numbers appear to be compliant (standard format, correct digits), but in fact the risks are extremely high, as shown below:

lUnable to receive verification code

lRegistration successful but unable to log in

lMessages often bounce or have no response

lprone to being flagged by platforms"Batch number" or "robot" account

lThe account life cycle is short and will expire or be banned after a few days.

Therefore, in any case involvingUser contact, social account registration, customer private domain importIn other business, it must be completed in the first stepElimination of virtual numbersandPhysical card confirmation, otherwise subsequent investment will be greatly wasted.

Challenges in US number screening: It’s not enough to understand the format

Many teams initially mistakenly believe that number screening is"Look at the format starting with +1, 10 digits", or "check several online number segment lists", but the structure of US operators is far more complicated than imagined:

lan area code (such as213) May be shared by multiple operators

lSome virtual operators use the number segments of mainstream operators to disguise themselves.

lMVNO (Mobile Virtual Network Operator) uses AT&T and T-Mobile signals, but builds its own number segment

This means that even if the format appears to be completely compliant, if it is not recognized by the system,It is impossible to manually determine the true ownership of the operator, not to mention distinguishing"Virtual" and "physical".

The underlying logic of filtering physical cards: four dimensions that must be identified

In order to fundamentally solve the problem, you should focus on the following four dimensions when screening U.S. numbers:

1.Is the format legal?

The first step is to complete the international format verification and clean out spaces, short numbers, character symbols, and abnormal formats without country codes.

2.Is the country of affiliation correct?

US numbers start with+1 is the country code, but Canada and Puerto Rico also use similar number ranges. It is necessary to accurately identify the country to avoid miscasting.

3.Operator ownership information

Precisely identify which operator the number belongs to (e.g.AT&T, Google Voice, T-Mobile, etc.), this is the prerequisite for judging its stability and registration ability.

4.Whether it is a virtual card segment or a high-risk control segment

Combined with the system historical behavior database, determine whether it is frequently marked by the platform.VoIP segment, code segment or unstable number segment.

These four dimensions need to form a unified analysis report to facilitate the next step of importing the system, performing registration, establishing a private domain pool and other operations.

Digital Planet’s solution: from identification to distribution in one stop

Wide range of application scenarios

Digital Planet US number identification system is suitable for the following typical business needs:

Social account registration scenario

likeSet up account pools for Telegram, WhatsApp, LINE and other platforms. Eliminating virtual accounts can increase the registration success rate by more than 50%.

Overseas SMS reach scenarios

SMS marketing and verification code notifications can identify virtual segments that cannot receive codes and improve the delivery rate.

Private domain user pool import scenario

likeSCRM imports the mobile phone numbers of potential customers in the United States to determine in advance whether they are real user numbers and optimize the quality of the customer pool.

Advertising data cleaning

Obtained for deliveryLead mobile phone number, clean out the number segments that are unavailable or have high risk control, and reduce conversion loss.
