Top Virtual Number Questions


At AVOXI we strive to simplify and improve our buying process and customers' journey. Part of our plan to achieve this goal is to provide more descriptive and educational content.  Finding the right virtual number for your business can be time-consuming and confusing.  In this article, we provide answers to the most asked virtual number sale questions.

Types of Virtual Numbers, Callers Costs, and Restrictions

Virtual phone numbers have become a popular, cost-effective option for businesses of varying size and trades around the world. The cloud-based numbers offer improved call quality at reduced call costs for both businesses and callers alike. Below we explain:

  • The different types of virtual numbers
  • Associated costs to your caller
  • Number restrictions

International Toll Free Virtual Number (ITFS)

An International toll free number, or international 800 number, allows callers worldwide to reach your business without being charged. The general availability, competitive rates, and call forwarding flexibility make ITFS numbers a popular choice for businesses reaching out to customers internationally. Some countries have restrictions for calls from mobile devices which may include surcharges or limited accessibility.

Universal International Toll Free Number (UIFN)

A UIFN, or Universal International Freephone Number, is similar to an international toll free virtual number in that the caller isn't charged for the call. Unlike regular toll free numbers, a single UIFN number can be dialed toll free from various countries. There are over 50 countries in the UIFN number program, which is overseen by the International Telecommunication Union (ITU).

UIFNs requirements and restrictions

  • UIFN must be registered in at least two of the 50 countries and typically requires a significant, one-time setup fee.
  • Costs are based on each selected country, meaning the more countries accessing the number, the higher the cost.
  • UIFN has a different dialing format from toll free numbers and is not as easily recognizable.

Domestic Toll Free Virtual Number (DTF)

Domestic toll free numbers work similar to an International toll free virtual number in that they are free to the caller.  Being country-specific, these numbers can only be called within the originating country but are usually accessible from all in-country mobile networks.

Local Virtual Number (DID/DDI)

Local virtual numbers are available in thousands of cities around the world and help businesses establish a local presence in multiple locations without the cost of a physical office. Local callers pay a standard local calling fee, which varies based on their geographic location. Local DID/DDI virtual numbers can usually be dialed by callers around the world and provide full accessibility and availability through mobile and payphone. A caller dialing your number from abroad will, however, be charged international rates for the call.

Shared Cost Virtual Number

Shared cost numbers are country-specific phone numbers in the UK, Australia, Germany, Switzerland, France, Portugal, and the Netherlands - to name a few.  Call rates are generally lower for shared cost numbers since the cost is shared between the caller and the business receiving the call. Charges to the caller are typically the amount of a local phone call with the receiver paying the usage rate. Shared cost numbers provide great coverage within the country. While some domestic toll free or international toll free numbers may not be fully accessible in certain regions within a country like China, shared cost numbers provide full accessibility and availability through mobile phones.

Vanity Virtual Number

A vanity number is a DTF or UIFN virtual number that spells out a specific brand name or service.  Vanity numbers carry the same coverage and restrictions as a DTF or UIFN number. The added challenge is to identify and acquire just the right combination of numbers or words. Availability may be limited, have longer wait times and are generally more expensive.

How Do I Transfer an Existing Number to AVOXI?

Number porting, also known as number transfer, is a system that allows the end users to keep their existing virtual number while switching from one provider to another.  Let's walk you through the process step-by-step, assuming your existing number provider releases your number.

Number Transfer Requirements

Before you start the number transfer processes, we recommend you read over your existing contract and confirm a few important items.

  • Does your existing provider charge early cancellation fees? If so, how much?
  • Is your account in good standing order, or do you have outstanding balances?
  • What special features are active on your toll free number, and how do you go about de-activating them?
  • Does your new provider offer the same features and are these automatically activated upon transfer?

Required Documentation and Information

Once you are ready to start the virtual number transfer process, the next step is to get your number “released” from your existing provider. To do this, the following documentation is required:

  • A completed Letter of Authorization (LOA) form obtained from your new provider.
  • Customer's main contact on the losing provider's account.
  • Customer's Account Number, the Losing Provider's details (Company Name and Provisioning Contact).
  • The number we are porting.
  • A copy of your latest invoice.

How Long Does It Take to Transfer a Virtual Number

Number transfer timeframes vary based on country and number type, but are typically as follows:

  • USA 800 Toll Free Virtual Number: 3 to 7 days
  • International Toll Free Virtual Number: approximately 30 business days
  • United States Local Virtual Number (DID/DDI): 1 to 3 weeks
  • International Local Virtual Number (DID/DDI): 7 to 14 business days
