Universal International Toll-Free Numbers (UIFN)

A UIFN, or Universal International Freephone number, is similar to an international toll free number in that the caller isn't charged for the call. Unlike regular toll free numbers, a single UIFN number can be dialed toll free from various countries. There are over 50   countries in the UIFN number program, which is overseen by the International Telecommunication Union (ITU)

UIFNs requirements and restrictions include

  • UIFN must be registered in at least two of the 50 countries and typically requires a significant, one-time setup fee. 
  • Costs are based on each selected country, meaning the more countries accessing the number, the higher the cost. 
  • UIFN has a different dialing format to toll free numbers and is not as easily recognizable.
  • When you buy an AVOXI virtual number there are no setup fees or minimum contracts.
