Phone numbers have different formats across countries — this tool parses a phone number and formats it in standard representations: E.164 (the universal format), national format (with local conventions), and international format (with country code and grouping).
Output Formats
- E.164:
+14155552671— The ITU standard used by telecommunications systems, SMS APIs (Twilio, AWS SNS), and as the canonical storage format in databases - National:
(415) 555-2671— The format local users expect to see, varies by country - International:
+1 415 555 2671— Human-readable with country code, commonly used on business cards and websites
Country Detection
The tool auto-detects the country from the international prefix (+1 for US/CA, +44 for UK, +49 for DE, etc.) or you can select the country manually from the dropdown. Each country has specific rules for number length, area code format, and grouping conventions.
Use Cases
- Database normalization: Convert mixed-format phone numbers to a consistent E.164 format for storage
- API integration: SMS and voice APIs require E.164 format — validate before making API calls
- Contact import: Parse phone numbers from CSV files or vCards into your preferred format
- International communication: Determine the correct international dialing format for any country
