How to filter the German mobile phone numbers imported in batches to be available or unavailable? What tools are recommended?

In practical scenarios such as cross-border traffic diversion, adding friends on social media, and building private communities, operators often obtain a large number of German mobile phone numbers. These number sources may include advertising leads, registration forms, third-party data providers, or compiled from a pool of historical customers.

But in actual use you will find:Can't join, can't chat, can't create a group, the reach rate is extremely low, and the script even runs badly.

The reason is clear:Which numbers did you not filter first?"available" and which numbers are "unavailable".

The mobile number is not"The more quantity, the better", but "the more valuable it is, the more operational it is."

This article will focus onThe theme of "Batch Screening of German Mobile Phone Numbers" was developed, and combined with the capabilities of the Digital Planet platform, a set of practical and efficient processing logic was provided.

1. AvailableWhat is the difference between vs unavailable mobile phone number?

In social operations, the real"Available" German mobile phone numbers usually have the following characteristics:

lRegistered on mainstream social platforms (such asWhatsApp, Telegram)

lNon-virtual segment, non-coded platform number

lRecently active, with a profile picture or traces of usage

lNon-blocked accounts, non-abnormal accounts with too many complaints

lCan be successfully added by script or private chat with customer service

And so-calledEven if "unavailable number" is written correctly, it will cause the following problems in actual use:

lRegistration status is empty, unable to add friends

lThe access number is frequently blocked, and the main account is implicated

lNo response or active behavior after joining the community

lThe hit rate of the script or customer service system is too low

lThe high proportion of duplicate, false and recycled numbers affects conversion statistics

Therefore, if there is no screening, all the words, scripts, and manpower invested subsequently will be lost in theRepeatedly consumed on "invalid target".

2. What are the common error screening methods?

Many people use the following methods to screen numbers, but these methods are unreliable:

lJust look at the format: Correct format does not mean registered, nor does it mean real user

lOnly view the number segment: The number segment can be used for preliminary screening of operators, but it is impossible to determine whether it is a virtual number or a cold number.

lRandom sampling test: The random inspection of some numbers is successful, but it does not mean that the entire batch of numbers is qualified.

lJudging by failure to add friends: Exclude it after it cannot be added. It is too late.

lUse directly without sieving at all: The script execution success rate is extremely low and may trigger risk control

Truly efficient data use must be based onBased on "structured screening".
