Virtual Phone Numbers

virtual phone numbers

United World Telecom offers different types of virtual phone numbers in more than 160 countries across the world: local, international, universal numbers. These numbers are often also identified as DID numbers, UIFN, or ITFS numbers. But what separates virtual numbers from regular numbers the most is the access to additional features and services. With a virtual number subscription, businesses can take advantage of Rollover Minutes, IVR, and Outbound Calling. Here is more information about the different types of virtual business numbers:

Toll Free Numbers

Want to provide a free way for customers to call your business? Toll free numbers are a good solution as they charge the receiver instead of the caller. You can get different types of international toll free numbers based on which country you want to do business with. In fact, you can even get toll free numbers that are mobile-accessible. Note that this may not be applicable to all countries. For example, virtual toll free numbers are accessible on mobile networks in the United States and Canada. But this is not the same for other countries. Additionally, calls made to such numbers on mobile networks may not be free. Keep this in mind when you consider purchasing a toll free business number.

Geographic / Local Numbers

Geographic or local numbers are numbers linked with specific locations within a select country. These are numbers with area codes for different cities, states, and regions. For example, you can get a New York city number or a Texas number within the United States.


National numbers are similar to geographic numbers in that they are assigned to specific countries and can be easily dialed using smartphones, landlines, or payphones. These numbers may not all be reachable from outside the specific country. The limitations vary from country to country.

Universal International Freephone Number (UIFN)

Universal International Freephone Numbers (UIFN) or Universal Toll Free Numbers are types of international toll free numbers. These numbers can be dialed and called from a variety of countries spread across the globe. To call this number, users must dial the appropriate access code, that enables international service, followed by the UIFN. Note that there are one-time-only setup charges when registering a UIFN number.

Mobile Virtual Numbers

Mobile numbers can be dialed using any communication device: smartphones, tablets, computers, landlines and even pay phones. A major benefit of these numbers is that they are reachable from other countries as well. They, however, cannot receive fax transmissions.
