International Calling Codes: A Business Guide

International Calling Codes: A Business Guide

International Calling Codes for Business

If your business serves international customers, understanding country calling codes is essential. Here is what you need to know about reaching customers worldwide.

Most Important Country Codes

  • +1 — US and Canada (shared code)
  • +44 — United Kingdom
  • +86 — China
  • +91 — India
  • +81 — Japan
  • +49 — Germany
  • +33 — France
  • +61 — Australia

Toll-Free for International Customers

US toll-free numbers (800, 888, etc.) only work for callers within the US and Canada. For international customers, consider a Universal International Freephone Number (UIFN) or provide a local number in their country that forwards to your US line.

Pro Tip: For businesses serving both US and international customers, a memorable US toll-free number plus a VoIP system that accepts international calls is the most cost-effective solution.
