Cross-border number screening is a necessary operation for overseas companies before acquiring customers, reaching users, and performing marketing. Especially inIn 2025, changes in the global data environment are accelerating, and number security, activity and compliance have become more complex. Simply relying on manual cleaning or static format judgments can no longer meet actual needs. If companies want to improve their reach rate and ROI in the international market, they mustCross-border number filteringEstablish a clear, practical and systematic operation plan.
Import failed and identification errors often occur?
When many teams first come into contact with cross-border number filtering, the most common problem is that data import fails or filter results are one piece."Invalid number". This is usually not a platform error, but a defect in the previous data format. In particular, inconsistent number prefixes, missing country codes or confusing formats will directly lead to difficulty in identification.
For example, in the Southeast Asian market, some users leave numbers with local numbers (excluding country codes), and some users register through different channels, resulting in the same number in different forms, such as"08123xxx" and "+628123xxx", seem to be different, are actually the same user. If a unified conversion is not performed during importing and filtering, it will cause repeated detection or direct identification to fail.
Standard formatting is the first step to success in filtering
To improve screening efficiency, enterprises should unify the number format during the data preparation stage, and it is best to use"Country Code + Complete Number" format, such as +44XXXXXXX, +62XXXXXXX, etc. This method is not only conducive to system identification, but also facilitates subsequent standardized use on SMS platforms, WhatsApp, Meta advertising and other channels.
The digital planet number screening detection platform supports automatic identification of common country codes, but in order to ensure accuracy, enterprises still recommend basic cleaning of numbers, including removing spaces, unified separators, and removing invalid symbols (such as"-" "/" "()").
Confused field naming can also affect filtering efficiency
Another often overlooked detail is the field naming issue. Some companies areIn Excel, different naming methods such as "mobile phone number", "contact information", and "number" are used. Some contain multiple contact fields in the table, which makes the system unable to accurately identify which column is the main field used for detection.
The practical suggestion is to use the unified field name before uploading"phone" or "number" and make sure there is only one main number per line. This can greatly improve the platform identification efficiency and accuracy. Digital Planet Platform supports field custom mapping, but keeping specifications is always the most efficient way.
Platform usage tips: How to use digital planets to screen out high-value data
The digital planet number screening and detection platform has adapted to the rules of mainstream countries and operators around the world, and supports batch import detection, automatic format recognition, and status classification output. Users only need to upload the sorted data files, and the platform will return various types of detection results including valid numbers, empty numbers, invalid numbers, and risk numbers within a few minutes.
The filtered results can be customized and exported, and support fields including country, operator, detection status, availability and other fields, which facilitates direct connection between SMS platforms, social platforms or internalCRM system. The platform also supports "delivery tags" based on the detection results, such as "first round of sending", "resurrecting users", and "verification required", to help enterprises use filtering data more intelligently.
How to avoid repeated detection and data loss
In multi-channel delivery or long-term operation, enterprises often conduct multiple inspections on the same batch of numbers, which not only wastes resources, but may also cause data confusion. The Digital Planet Platform supports historical detection record comparison function. Enterprises can upload old data to compare new data, filter only new or unprocessed parts to avoid repeated operations.
At the same time, it is recommended that enterprises add time marks and batch numbers to the export files selected each time, so as to facilitate tracking the delivery effect and screening efficiency in later statistical analysis.
How to increase the value of filtered data
FinishCross-border number filteringAfter that, the most important thing is how to use these results well. Enterprises can directly connect valid numbers to the SMS platform to provide high hit rate registration reminders, verification codes or marketing notifications. For high-risk or abnormal format numbers, they can be transferred to manual review or not used for the time being to avoid affecting the health of the channel.
There is a company that provides cross-border financial services. After screening out high-quality numbers through the Digital Planet Platform, it has built an independent SMS marketing library andWhatsApp customer library, the cost of delivery has been reduced by about 40%, but the conversion has been increased by nearly 70%.
