Universal International Freephone Numbers (UIFN)

A Universal International Freephone Number (UIFN) number is simply a universal toll free number. Just like international toll free numbers, universal freephone numbers allow prospects and customers to call you at no charge. Unlike regular toll free numbers, a single UIFN number can be dialed toll free from many different countries. Over 60 countries participate in the UIFN number program, which is overseen by the International Telecommunication Union (ITU). A once-off ITU registration fee is required for new UIFN numbers.

How Universal Toll Free Numbers Work

Universal toll free numbers include the “00800” prefix followed by 8-digits. Each country has a unique 3-digit international access code that a caller must dial to connect to a UIFN number. For example, the UIFN format for a caller from the UK would be:

  • (00) +800 XXXX-XXXX.

See above for a complete list of UIFN country participants and their respective international access codes.
