Practical solution for international mobile phone number format detection and T card differentiation

When conducting marketing outreach, social account registration or user acquisition on a global scale, the effectiveness and availability of batch mobile phone numbers has become an unavoidable issue for enterprises. When cleaning numbers, many teams only make basic format judgments, but ignore the deeper"Card type" difference: virtual T card and physical SIM card. Such differences often directly determine the success of subsequent business.

In order to deal with this problem,International mobile phone number format detection+T card distinctionBecome the most practical combination strategy in the current screen size. This article will share the core principles, usage scenarios and recommended platforms of this solution.

Why can't we just look at the format?

In the preliminary cleaning stage, most companies adopt the format standard judgment method.——For example, whether it contains the country code, whether the number of digits is compliant, whether it contains illegal characters, etc. However, in actual use, even if the format is correct, there may be the following risks:

lThe number isT card(provided by virtual operator), unstable or short-term invalid

lAlthough it is in normal format, it does not support registration of specified platforms (such asiMessage, Telegram, LINE)

lVirtual number segments are registered and used in batches, which can easily trigger platform risk control

lAlthough the number segment is compliant, it belongs toHigh-frequency use paragraphs of the coding platform

In other words, it only has the format detection capability and only completes the number cleaning."Introductory steps", but to achieve substantive screening, they must also be completed simultaneouslyThe difference between T card and entity number.

Format detection: global standardization and local differences coexist

There are huge differences in the structure of mobile phone numbers in different countries. For example:

lThe US mobile phone number is fixed at10 digits, but there are a lot of virtual paragraphs in the area code

lThe first digit of an Indian number distinguishes the type of operator

lCountries such as Indonesia and the Philippines have a large number ofVoIP segment number, existing in parallel with the physical card

lSome countries in the Middle East and Africa use different formats, and format judgment is unreliable.

Therefore, to unify format judgment, the system must have the following capabilities:

lSupports automatic recognition of multi-national formats

lAutomatically calibrate the corresponding relationship between country code and number segment

lCompatible with variable-length number countries (such as Thailand, Nigeria)

lEquipped with a custom regular rule mechanism(Adapt to updated rules for emerging countries)

T card recognition: in-depth operator paragraph recognition logic

T cards are commonly used in the following situations:

lVirtual operators (such asVOIP number provided by Google Voice, TextNow)

lBatch registration number segments used by the universal code receiving platform

lShort-cycle card segments purchased in bulk by international SMS service providers

lThe binding number generated by the virtual communication platform used by the enterprise (notSIM card)

Although these numbers can receive verification in a short period of time, most of them cannot be used continuously and stably, or are judged by the system as low-reputation accounts, which are easy to be banned and cannot maintain accounts.

Identifying this type of number requires accurate judgment based on multiple dimensions such as global operator data, historical black segment marks, activity and location verification.
