Mobile phone number filtering is a standard process in cross-border marketing, suitable for 100,000-level data processing
Many people will understand number filtering as simply filtering numbers, but the process that is truly suitable for 100,000-level data processing is no longer just checking whether a number exists, but a complete set of front-end data sorting logic. After the numbers enter the system, they need to unify the format, complete deduplication, detect platform status, identify activity, and then further classify based on user quality. Only in this way can the subsequent operating system be truly stable.
