What is a Phone Number Format?
Phone number formatting is the process of converting a phone number into a standardized format that follows international or local conventions. Proper formatting ensures phone numbers are displayed consistently and can be dialed correctly across different systems, platforms, and countries.
Without standardized formatting, the same phone number can be written in dozens of different ways, leading to:
- Data inconsistency in CRM systems
- Failed integrations between platforms
- Duplicate contact records
- Click-to-dial functionality issues
- International calling complications

Do I need to include the country code?
