Country-to-country dialing walkthroughs

These examples use X placeholders or reserved fictional-use patterns, not private subscriber numbers. The + version is the portable format to save in contacts; the digits-only version shows how the same destination can look when the origin network requires an international prefix.

Plus sign, exit codes and carrier variations

Save the destination in + format because the plus sign adapts to the network where the call starts. If a phone or carrier requires digits, replace + with an access prefix from the origin country; never save that origin prefix as part of the destination number.

Calling fromCommon digits-only accessPractical variation
United States011Use + where supported; the digits-only prefix is an origin routing instruction.

Which regional exceptions matter most?

  • Shared numbering plans

    +1 covers the United States, Canada, and multiple Caribbean/Atlantic jurisdictions; the next digits resolve the destination.

  • Significant leading zero

    Italian geographic numbers retain 0 after +39, unlike the removable trunk zero used by many countries.

  • Carrier-selection prefixes

    Brazilian routing strings may contain a carrier code that must not be saved as part of the +55 destination number.

  • Overseas territories

    A territory may share a parent code or use another code, so political association alone does not determine the dial string.

Handle the exceptions

Shared top-level codes, toll-free ranges and travel networks need more than a country-code substitution.
