Phone Number Formats

E164: International standard format (+CountryCodeNumber). International: Full format with country code. National: Local format without country code. Local: Regional formatting with area codes. Each format serves different purposes: international for global use, national for local display, E164 for storage and systems.

Validation Techniques

Format Check: Validates pattern and length for each country. Country Detection: Identifies country from country code. Carrier Lookup: Determines mobile/landline and carrier (simulated). Type Detection: Distinguishes between mobile and landline numbers. Region Analysis: Identifies geographic region and area codes. These techniques ensure comprehensive phone validation.

Phone Number Best Practices

International Format: Always store in E164 format (+CountryCodeNumber). Validation: Check format and length for target country. Normalization: Remove formatting characters before storage. User Experience: Display in local format, store in international format. Testing: Validate with sample numbers from each target country. These practices ensure reliable phone number handling.
