A Universal International Freephone Number (UIFN) is a single toll-free number that works across multiple countries — making it easy for your customers to reach you from different parts of the world without paying for the call. Instead of juggling separate numbers for each market, you can advertise one consistent phone number across participating countries.
Global Call Forwarding’s UIFN service connects you to your customers with 99.999% uptime, enterprise-grade call quality, and powerful cloud communication features—all on a single, scalable platform.
UIFN & International Freephone Numbers
UIFN is part of the International Telecommunication Union’s (ITU) global freephone program. Your UIFN is composed of:
- Three-digit country code (800)
- Global Subscriber Number (GSN) — 8 digits
This makes an 11-digit number accessible in participating countries.
When a customer dials your UIFN, the call is routed to your designated destination — whether that’s your headquarters, a remote office, or your cloud phone system — with no cost to the caller. A UIFN number can work in more than 60 different countries.
Participating Countries
UIFNs are not available worldwide — they work only in countries that participate in the ITU UIFN program.
Currently, coverage is limited to 60 countries, mostly in Europe, Asia-Pacific, and the Americas.
Tip: If your business needs toll-free coverage in countries that do not support UIFNs, you can still achieve near-global reach with International Toll-Free Numbers (ITFS) or local virtual numbers from Global Call Forwarding.

Is UIFN Right for You?
Choose UIFN if:
- You advertise to 3+ countries regularly
- You want to maintain a consistent brand presence globally
- You need one central number instead of multiple country-specific lines.
Important Considerations:
- Higher Setup Costs: UIFNs require a one-time setup fee that is typically higher than the cost for individual ITFS.
- Limited Coverage: UIFNs are only available in 60 participating countries, which is fewer than the coverage available with ITFS numbers.
- Strict Regulations: Many countries require businesses to meet local compliance rules for UIFN registration. This can include longer provisioning times, specific documentation, and occasional in-country address requirements
If you only serve one or two countries—or want broader global coverage—choose ITFS numbers. Also see our Toll Free FlexDial solution for wider coverage flexibility.
