FAQ
-
What is E.164 format and why does it matter?
E.164 is the international telephone numbering standard defined by the ITU. It specifies a maximum of 15 digits starting with a country code prefix (e.g., +14155552671). It matters because it is the universal format used by telecommunications carriers, VoIP services, and APIs like Twilio and AWS SNS to route calls and messages globally.
-
How do country calling codes work?
Country calling codes are 1-3 digit prefixes assigned by the ITU to each country or territory. For example, +1 covers the US and Canada (the North American Numbering Plan), +44 is the United Kingdom, and +91 is India. When dialing internationally, you use the exit code followed by the country code and the subscriber number.
-
What is the difference between mobile and fixed-line phone numbers?
Mobile numbers are assigned to wireless cellular devices and can move with the subscriber (number portability). Fixed-line numbers are tied to a physical location and connected via landline infrastructure. Many countries use different numbering ranges to distinguish them, though number portability has blurred these boundaries in some regions.
