Phone Number Classification Export

The phone number classification export tool can help you classify large quantities of phone numbers by different categories and export them as text files. Supports multiple classification methods such as province, city, operator, area code, zip code. This is very useful for data analysis, marketing strategy development, customer service and other scenarios.

Using this tool is very simple:

1. Enter phone numbers in the input box, one per line
2. Select classification type (by province, city, operator, area code, zip code)
3. Click the "Start Classification" button and wait for classification to complete
4. Select the classifications you want to download in the results (can select all or invert selection)
5. Click the "Download" button to package the selected classifications as a ZIP file for download

This tool runs completely locally in the browser, all data processing is done on your device:

• All classification operations are done locally in the browser, not uploaded to the server
• Database files are stored locally, can be used even when offline
• We do not obtain any content you input, completely protecting your privacy

Theoretically no limit. This tool can process millions or even tens of millions of phone numbers for classification at once. If input exceeds 1 million lines, the browser may have brief lag, please wait patiently.

The exported file is a ZIP archive containing multiple TXT text files. Each file corresponds to one classification, with filename format: ClassificationName_Count.txt. For example: "Anhui_1234.txt".

This tool classifies based on phone number segment database. For recorded segments, classification results are accurate and reliable. However, due to possible update delays in the segment database, some new segments may show as "Unknown".
