The Mobile No. field in Phone Routing Rules requires the country code to ensure accurate and consistent matching of phone numbers. Here’s why:

Reason for Requiring the Country Code:

  • Phone numbers vary in format depending on the country, and including the country code (e.g., 91 for India) ensures the system can uniquely identify the number regardless of how it’s formatted in the message.
  • Without the country code, the system might misinterpret the number, leading to incorrect routing or missed matches.
  • Example: 9199999xxxxx clearly identifies an Indian number, while 99999xxxxx could belong to multiple countries, causing ambiguity.

How to Format the Mobile No. Field:

  • Always include the country code without the + symbol (e.g., 9199999xxxxx for an Indian number).
  • Ensure the number matches the format used in your messaging system for consistent rule application.

Best Practices:

  • Verify the country code for the phone number you’re targeting (e.g., 91 for India, 1 for the USA) before entering it in the Mobile No. field.
  • Test the rule with a sample message to confirm the number is matched correctly and routed to the new vendor.
