Phone Number Anonymization Free Tool

Phone number masking is a privacy protection technique that replaces parts of phone numbers with placeholder characters (typically asterisks or other symbols) while maintaining the overall format. This allows businesses and individuals to share contact information without exposing complete phone numbers, protecting user privacy while preserving data utility for verification and reference purposes.

Yes, our phone number masking tool offers a generous free tier with 10 phone numbers processed per batch at no cost. For larger batch processing needs, we offer affordable pay-as-you-go pricing starting at $1 per 50 numbers. No subscriptions or hidden fees required.

All phone number processing happens directly in your web browser using JavaScript. No phone numbers are ever transmitted to our servers or any third-party services. This zero-knowledge architecture ensures your data never leaves your device, providing maximum privacy protection and compliance with GDPR, CCPA, and HIPAA requirements.

Phone number masking methods include: (1) Start masking - hides the first digits while keeping the last 4 digits visible; (2) Middle masking - hides the middle portion of the phone number; (3) End masking - hides the last digits while keeping area code visible. Each method serves different privacy needs while maintaining the overall phone number format.

Yes, our tool supports bulk processing of phone numbers. You can paste multiple phone numbers directly (one per line) or upload a CSV file containing phone number data. The tool automatically detects and processes phone numbers in various formats, making it efficient for handling large datasets while maintaining data privacy.

Yes, we offer API access for developers who need to integrate phone number masking into their applications and workflows. The API supports all the masking methods available in our web interface and maintains the same client-side processing architecture for maximum privacy. API access is available with our Standard and Enterprise plans.
