New standard for global marketing data cleaning: Use Dingdang Assistant to easily identify the country of a number

In the era of cross-border marketing and global customer service, companies are exposed to massive amounts of phone number data every day: clues from advertising, registration information of overseas customers, third-party list resources... However, these data are often mixed with numbers from different countries, without clear attribution marks.
When an enterprise attempts to launch overseas SMS promotion or outbound calls, incorrect number attribution not only wastes costs, but may also violate local communication regulations. How to accurately identify the country of each number and classify it efficiently by country is a key step in global marketing data management.

Dingdang Assistant was born just for this. It uses intelligent algorithms and international number segment database to achieve "automatic identification + classification export", helping enterprises to escape from data chaos and move towards truly global data operations.

Why cross-border marketing is inseparable from number ownership identification

For marketing practitioners, phone numbers are not only “contact information” but also an important user feature. Numbers in different countries mean different communication methods, languages ​​and time zones, as well as different compliance requirements.

Strategically differentiated communication : sending Chinese text messages to Japanese users? Not only is it invalid, it may even be blocked. After accurately identifying the country of origin, companies can formulate targeted content and time strategies.

Cost and sending success rate optimization : The cost of communication channels in each country is different, and incorrect attribution will cause the failure rate to soar.

Compliance and brand protection : Some regions (such as the European Union and Australia) have strict restrictions on cross-border communications. Posting the wrong content may carry the risk of fines.

In this context, number ownership identification has become an indispensable front-end link in global marketing .
