What is UIFN ?
A Universal International Freephone Number (UIFN) enables an International
Freephone Service (IFS) customer to be allocated a unique freephone number(s)
that is the same throughout the world.
A UIFN is composed of a three-digit country code for global service application,
i.e. 800, followed by an 8 digit Global Subscriber Number (GSN), resulting in an
11digit fixed format. (An IFS caller must dial an international prefix prior
to the UIFN.)
The Telecommunication Standardization Bureau of the ITU has been requested to
perform the task of Registrar for UIFNs, responsible for processing registration
requests and assignment of the GSN portion of the UIFN in accordance with ITU-T
(new) Recommendation
E.169 and (revised) Recommendation
E.152 , "International Freephone Service".
Who can apply for UIFN?
Only an international telecommunication recognized operating agency (ROA), as
defined in the ITU Constitution, can submit an application on behalf of
the IFS (International Freephone Service) customer in accordance with
Recommendations E.169
and E.152.
National Administrations may, as a national matter, choose to coordinate
applications from their ROAs, or act as applicant on behalf of, their ROAs.
UIFNs will be assigned to IFS customers who intend to use the IFS service
between two or more countries, in other words IFS customers offering a service
that is only accessed from within a single national, or integrated numbering
plan, will not be considered eligible.
In order to be qualified for a UIFN number, the number has to be in-service
between two or more countries within 180 days from the date of its reservation
with the UIFN Registrar otherwise it will be cancelled.
The UIFN Format
A UIFN is composed of a 3-digit CC (ITU-T
Recommendation E.164 country code) for a global service
application, 800 and an 8-digit Global Subscriber Number (GSN),
resulting in an 11-digit fixed format.
As an example, an IFS customer's UIFN could be
+800 12345678, where 12345678 being the IFS customer's GSN.
An IFS caller must dial an international prefix
prior to the UIFN.
