Batch screening of international mobile phone numbers, what data problems can be solved by country, format and platform status
When international customer numbers are mixed together, the real trouble is often not the numbers but the country codes, number formats, duplicate data and platform status all mixed together. Numbers such as +1, +44, +66, +84 come from different numbering systems. If local formats and international formats exist at the same time, subsequent detections on WhatsApp, Telegram, LINE, etc. will be more likely to be repeated. What really needs to be solved in batch screening of international mobile phone numbers is to first make the numbers identifiable, and then supplement the number status and the actual required platform account information.
