Use a TXT or CSV file, or paste up to 100,000 input rows.
Extract mobile numbers
Extract mobile numbers for the selected country or region.
Choose an export

Cleanup is not validation
Cleanup extracts and formats numbers for the selected market. It does not tell you whether a number is active, registered on a messaging platform, or owned by a particular person.
Data handling
The current SaaS interface states that processed results are not stored. Use only data you are authorized to process.
