# Connect Customer support of the inbound only UIFN service
A Universal International Freephone number (UIFN) is a unique **inbound only** freephone number that can be used throughout the world. It provides toll-free calling from international locations to your contact center.
Connect Customer supports UIFN in more than [60 countries](#list-of-uifn-countries) that are registered with the International Telecommunications Union, an organization that supports the administration of the UIFN service.
**Note**
Connect Customer allows you to enable UIFNs in as many countries as you need, however, it requires a minimum of 5 countries.
A UIFN is composed of a 3-digit country code for a global service application, such as **800**, and an 8-digit Global Subscriber Number (GSN). This results in an 11-digit fixed format.
For example, your UIFN could be \+800 12345678, where 12345678 is your number.
Due to the special nature of UIFN, attempting to call a UIFN from Connect Customer in a "loopback mode" is not supported. UIFNs are designed to be called from end phone configurations in the country's public telephone network.
## How to get a UIFN
To request a UIFN within a specific AWS Region, create an AWS Support case. In the support case, provide the following information.
+ Choose the countries you want to enable from the [list of available countries](#list-of-uifn-countries).
+ The Connect Customer instance(s) associated with the new UIFN numbers. Connect Customer can support routing numbers to multiple Regions, such as Australia to the Asia Pacific (Sydney) Region, United States to a US Region, or if desired to a single global instance.
+ The required ID verification for your country. Most countries subscribe to [standard ID verification requirements](phone-number-requirements.md#uifn-requirements) for ordering UIFN numbers. However, we recommend checking [Region requirements for ordering and porting phone numbers in Connect Customer](phone-number-requirements.md) for your country to be sure.
For number portability, after you open a case, Amazon will provide you with *Service Provider Change Authorization and Designation of Agency* document.
Connect Customer can route UIFNs to multiple AWS Regions. For example, if a UIFN is enabled for Australia, it can be routed to your Connect Customer instance that is located in the Asia Pacific (Sydney) Region. If a UIFN is enabled for **more** countries, each country can be routed to your Connect Customer instance, which may be in any supported AWS Region.
The following image shows the body of a sample UIFN request submitted to AWS Support. This request is for two UIFNs. The first is for a UIFN that is enabled for Argentina, Brazil, and Colombia, and connected to an Connect Customer instance in the US West (Oregon) Region. The second request is for a UIFN that is enabled for Japan, Australia, and New Zealand and connected to an Connect Customer instance located in the Asia Pacific (Singapore) Region.
**Important**
**UIFN is an inbound-only service**. Before opening a ticket to request a UIFN:
Ensure you understand that this number cannot be used for outbound.
Check the National reachability of the country in the following section.
Full National reachability means the UIFN reaches all local (in-country) networks. UIFNs in some countries have limited reachability and will only work with specific carriers/networks where you need to use different codes to dial the number (for example, Japan).
