Virtual Phone Numbers

View All Features

United World Telecom offers local, international, and universal virtual phone numbers (also known as DID numbers, ITFS numbers, or UIFN numbers) in over 140+ countries loaded with features and additional service options such as SMS, outbound calling, and rollover minutes. Here are some of the types of virtual phone numbers we have available.

Toll Free Numbers

Toll free numbers are telephone numbers dialed without any charges to the caller. There are a few different kinds of toll free numbers depending on the country. In the United States and Canada toll free numbers are also accessible via mobile networks. In other countries, toll free numbers are not always mobile accessible.

There are mobile accessible toll free numbers available in some countries which can be dialed from landline and mobile networks, but it’s important to note that in some countries calls to toll free numbers from mobile networks are not always free depending on regulations.

Geographic / Local Numbers

Geographic numbers are numbers that are tied to a specific location within the selected country. In the US, a geographic number might have a specific “area code” for a city or region. Geographic numbers are SMS capable (optional) in many countries.

Universal International Freephone Number (UIFN)

Also known as Universal Toll Free Numbers, UIFN numbers are international toll free numbers which can be dialed from multiple countries. This can be done by dialing the access code for international and the rest of the toll free number. There is a setup charge associated with registering a new UIFN number.


Mobile numbers can be dialed from mobile phones, landlines, pay phones, and most of the time from other countries. They can’t receive fax transmissions. Some of these mobile numbers have SMS optional depending on the country.


National numbers work within the selected country and have SMS capabilities (optional). They can be dialed from mobile phones, landlines, payphones, and (some) other countries.

Number Parking

Cancel your landline and keep your phone number with our number parking service. It’s simple!

We charge you a (very) small monthly fee to keep your number without any service / minutes. When someone calls your number, they can be presented with a message/recording, but will not be connected anywhere. There is no contract, no commitment, and you can cancel or port your number out at any time.

The cost is usually a few dollars per month, depending on the country the number is based in, but can vary depending on the country the number is based.
