Tips for batch deduplication of millions of mobile phone numbers

Power-on and online filtering provide real-time insights into user activity patterns, making community management more efficient and advertising more targeted.

The root cause of high costs in cross-border marketing lies in "resource mismatch"—investing budgets and energy in ineffective accounts. WhatsApp account screening is key to solving this resource mismatch.By using ITG's full-domain filtering, enterprises can efficiently eliminate invalid numbers and focus on high-value customers, achieving a triple optimization of "reduced push costs, improved manpower efficiency, and saved opportunity costs".

In today's increasingly competitive cross-border marketing environment, "cost control" is just as important as "effectiveness improvement".Prioritizing WhatsApp account screening and using ITG's comprehensive filtering to build a precise and effective customer pool is crucial to maximizing the value of every marketing investment and achieving low-cost, high-efficiency growth in cross-border business.However, many companies overlook a crucial step: if they only generate global phone numbers without using number screening tools, a large number of invalid and risky numbers will directly trigger the platform's risk control, leading to the banning of marketing accounts and business interruption.

In fact, global phone number generation must be used in conjunction with professional number screening tools (such as ITG Global Screening) to avoid the risk of account blocking and ensure the stable progress of cross-border marketing.This article will analyze why global phone number generation is inseparable from number screening tools, and how ITG's global screening can help with risk control.

Relying solely on globally generated phone numbers and using them directly for marketing without filtering will trigger account bans based on three dimensions: "number quality, platform rules, and user complaints."

Through multi-dimensional screening, "virtual numbers, high-complaint numbers, and linked banned numbers" are removed from the global phone number pool, retaining only "real, valid, and low-risk" numbers.In Telegram (TG) marketing and customer acquisition, "account suspension" is the most troublesome problem for businesses – hard-earned customer resources cannot be reached due to account bans, and rebuilding an account requires a lot of time.

Many people are unaware that the root cause of frequent account bans often lies in the hidden dangers that arise during the "account screening" process.Professional Telegram account screening can help businesses avoid risky accounts and reduce invalid operations from the source, thus preventing Telegram platform risk control measures from being triggered.

Leveraging ITG's comprehensive screening capabilities, the TG account screening function can further protect TG accounts from banning risks and ensure stable operation through risk identification, compliance screening, and precise stratification.Many businesses skip or ignore the Telegram account screening process during their Telegram operations, using methods such as "blindly adding and randomly pushing" to acquire customers. These behaviors directly trigger Telegram's risk control rules, resulting in account restrictions or even bans.
