Customers in Austria and Germany dial the business’ respective toll free numbers at no charge to them. And, the business can forward the calls to their main office in the United States.

Universal International Freephone Numbers (UIFN)

Universal international freephone numbers, or UIFN numbers, are the closest thing to a “global” toll free number that you can buy. Like international toll free numbers, they are free for your customers to call. But, this number can apply to multiple countries.

UIFN numbers are currently available from nearly 50 countries world. But, there are some things you should know before you buy one. UIFN numbers:

  • Must be registered in at least two countries
  • Typically require a significant, one-time setup fee
  • Incur costs for each country selected—the more countries accessing the number, the higher the cost
  • Have a different dialing format than toll free numbers, and may not be recognisable as free to call for all customers

Who uses UIFN services?

We get many requests for “global” toll free numbers from all kinds of businesses, ranging from software development companies to high-end resorts. These businesses want to be able to provide their customers, regardless of where they are located, with a single phone number to reach customer service, support, or account management.

It is important to remember that UIFN numbers are not available in all countries. If you are looking for a “universal” or “global” free phone numbe, be sure to have the countries that you plan to target in mind before you speak to a provider. This will help you narrow down your search for the right provider.

Which Type of International Toll Free Number Is Right for My Business?

There are lots of different business models, just like there are multiple kinds of international toll free numbers. We have found that, in general, the following types of businesses benefit from different types of international toll free numbers:

Retail/Consumer Goods and Insurance

Businesses in retail/consumer goods and insurance typically cater to customers in a few countries. It’s more cost-effective to purchase 2 or 3 international toll free numbers than to pay the additional cost for a universal international freephone number when you are only targeting 3 or 4 countries at most.


Hospitality is divided into two segments: travel services and hotels, motels, and resorts. Regardless, most hospitality companies could benefit from a UIFN number. Their clients travel to a wide variety of countries. Since they aren’t familiar with local phone number formatting, it’s better to provide all customers with a single phone number for support in-country.

Technical Support

Most technical support companies provide service to customers in-country. Several support one or two specific countries outside of their own. These businesses can use both international toll free numbers and domestic free phone numbers to provide their customers with a way to contact them at no charge.
