UIFN or ITFN: Which is Best for Your Business?

Source: - Lic#374849482 #27446420

When you consider expanding your business to neighboring countries, one of the biggest concerns to consider is: how will you maintain communications and customer support with individuals in this part of the world? International phone numbers are one way to maintain reliable communication. And virtual phone service providers have two options for you: ITFN and UIFN.

UIFN versus ITFN

Which is a better number type for your business? To determine whether your communication system will work better with an ITFN or UIFN number, you first need to know how these numbers work and how they differ from each other.

What are International Toll Free numbers?

International toll free numbers (ITFN) are telephone numbers that are free to dial and can connect you to a representative in a different country. Businesses can use ITFNs to provide a free method for customers to call them. You can get an ITFN for any country that you want to expand operations to or provide customer support. United World Telecom offers ITFN numbers for more than 160 countries across the globe. Incoming calls are forwarded internationally to any number or line located anywhere in the world.

Therefore, even if your company is located in the US, you can get a UK toll free number (an 0800 or 0808 freephone number) and have incoming calls forwarded to your US office line. This enables free calling for customers and business contacts in the UK.


  • Choose from a list of 160+ countries to expand operations to.
  • It is the most cost-effective option for any company wanting to expand globally.
  • You may forward incoming calls to any location, as needed.


  • You will need a different ITFN number for each country you want to expand to.

How do Universal International Freephone Numbers Work?

A Universal International Freephone Number — also known as a Global Toll Free Number or UIFN — is a type of international toll free phone number that works in multiple countries through a single number. With a UIFN number, customers and contacts in up to 45 different countries can connect with you through that one toll free number. Here is a list of the countries where UIFN numbers are available, including information about mobile accessibility:

Country Mobile Country Mobile

While UIFN numbers sound good in theory, when deciding what number type works best for your business, one must look at advantages and disadvantages.

Advantages of UIFN:
A UIFN is a single toll free number for multiple countries, including popular locations such as Australia, Canada, Germany, Hong Kong, etc.
Having a single number makes it easier to manage communications instead of displaying a variety of numbers.

Disadvantages of UIFN:
UIFN are accessible from only 45 countries around the world. International toll free numbers, on the other hand, give you access to more than 160 countries across the globe.

These numbers, most of the time, require specific prefixes to be dialed before the number. These prefixes vary based on the country which can lead to confusion and misdialing.

Not all countries within UIFN coverage are mobile-accessible (refer to the above list).
Registration fees apply.

Choosing the Right Number for Your Business

Which is better for your business depends on your business’ international reach. If you have customers in only a few select countries, then getting separate ITFN numbers for those regions will be more useful. However, if you have extensive global coverage, you may find UIFN more beneficial. This decision also depends on your budget limits and how much getting multiple ITFNs or one single expensive UIFN will cost you.
