Phone Number Validator

Phone number validation is a process that verifies if a phone number is correctly formatted, contains valid country codes, and follows international E.164 standards. It checks syntax, validates country codes against ITU-T specifications, identifies number types (mobile/landline), and ensures the number can be properly routed through global telecommunications networks.

E.164 is the international standard for phone number formatting defined by ITU-T. It ensures each phone number worldwide is unique and includes a country code (1-3 digits) plus subscriber number (max 12 digits), totaling up to 15 digits. This format enables proper call routing, SMS delivery, and compatibility with telecommunications systems globally.

Yes, our phone validator operates entirely client-side in your browser. No phone numbers are transmitted to servers, stored, or logged anywhere. All validation happens locally using JavaScript, ensuring complete privacy and security of your contact information. This makes it safe for businesses and individuals to validate sensitive phone data.

Our validator supports phone numbers from 200+ countries worldwide, including all ITU-T assigned country codes. It handles various formats including national, international, and E.164 formats. The tool recognizes country codes from +1 (North America) to +998 (Uzbekistan) and automatically detects formatting patterns for mobile, landline, and special service numbers.

Yes, our validator can identify number types including mobile, landline, VoIP, and special services based on number patterns and country-specific numbering plans. This information helps businesses choose appropriate communication channels, comply with regulations, and optimize marketing strategies for different number types.

Validating phone numbers prevents failed calls and SMS, reduces costs from invalid numbers, improves customer communication, and ensures regulatory compliance. It also helps maintain clean databases, prevents fraud, enhances user experience, and ensures compatibility with international telecommunications systems and automated calling platforms.

Format validation can achieve 95%+ accuracy in detecting syntax errors, invalid country codes, and formatting issues. However, it cannot verify if a number is currently active or reachable without actual carrier verification. Our tool excels at catching format problems, invalid codes, and structural issues that represent the majority of phone number quality problems.

Our validator supports both single number validation and bulk processing. You can validate individual numbers for real-time form validation or process multiple numbers (one per line) for database cleaning. The bulk feature is perfect for cleaning contact lists, validating imports, or maintaining database quality across CRM systems.

Yes! Our validator provides multiple export options including Excel/CSV format for spreadsheet analysis and PDF format for reports. You can also share results directly through your device's native sharing apps or copy them to clipboard. All export features maintain the same privacy standards - no data is sent to external servers.

Phone numbers change frequently due to carrier switching, number porting, and service changes. We recommend validating contact databases quarterly for active campaigns, before major communications, after importing new contacts, and when experiencing delivery issues. Regular validation maintains communication effectiveness and reduces costs from invalid numbers.
