Issuer Identification Number (IIN)
Fact Sheet
What is the ISO/IEC 7812 Numbering System?
The purpose of the numbering system is to uniquely identify a card issuing
institution in an international interchange environment. All IINs assigned are
six digit numbers and each card issuer is entitled to one IIN (outside of its
membership of any card schemes, for example an IIN assigned from Visa).
Therefore only one IIN will be assigned to each card issuer. This IIN must be used only to identify the card issuer. Additional IINs will
not be issued to identify products, services or geographical location.
How can I obtain copies of ISO/IEC 7812 Parts 1 & 2?
Copies of ISO/IEC 7812 are available electronically from the ANSI eStandards
Store at the following: http://webstore.ansi.org/.
How can I obtain the application form?
Application forms are contained in ISO/IEC 7812 Part 2, Annex A and are also
available upon request from ANSI’s Registration Coordinator. Photocopies of
this form are acceptable.
The application can also be downloaded from this page in
Word or
PDF format.
How do I complete the application form?
The applicant must complete Part A of the form as clearly as possible. Specific
sections of the form that may require careful consideration by the applicant
are:
Industry:
In this section of Part A of the application form, applicants should choose
the industry that is closest to the core business of the card issuer.
They should not choose a category that matches the intended
use of the card. If the business of the card issuer is not listed, then
applicants should state clearly what their core business is. The industry
chosen by the card issuer will decide the Major Industry Identifier (MII), the
first digit of the IIN. The MII does not in any way restrict or limit how the
card can be used.
Brief description of card usage:
Applicants should state the intended use/service that the card will perform
(debit card, credit card, ATM card, etc.). Organizations requesting a six-digit
international IIN should select "International Use" in this section.
Organizations requesting a nine-digit national IIN should select "National
Use." For more information on the national numbering system, please see below.
Is there an application fee?
There is a non-refundable, $1000 application fee
associated with processing this application. The fee should accompany the
application. ANSI accepts the following as payment: check, money order,
American Express, MasterCard & Visa.
Complete applications should be sent to the sponsoring authority, ANSI, at the
following address:
Jessica Carl
IIN Registration Coordinator
American National Standards Institute
25 West 43rd Street
New York, NY 10036
Applications can be also faxed to the following: 212.642.4888.
Note: Applications cannot be processed without accompanying fee. If the
application is faxed and the organization wishes to pay by check, the
Registration Coordinator will hold the application until such fee is received.
If the application is faxed and the organization wishes to pay by credit card,
please include complete credit card information on a separate page (including
card holder signature and CVN code). Please indicate that ANSI is authorized to
charge the card for the $1000 application fee.
What is the turnaround time for IIN assignment?
Once the completed application and application fee are received by ANSI, the turnaround time is typically within 5 business days.*
*Please note that the turnaround time for telecommunications applications is longer than the typical 5 business days.
What if I plan to issue cards nationally only?
The U.S. has developed the U.S. National Numbering System and ANSI is the
Registration Authority for this numbering system. This numbering system is
similar to the numbering system for ISO/IEC 7812 Parts 1 & 2.
What if I would like to apply to be an IIN Blockholder?
A Blockholder is defined as an entity that owns 2 or more IINs. If you are
located outside the United States, you will need to first obtain approval from
your country’s Standards Body to become a Blockholder. If you are located
within the United States, you will need to fill out an IIN Blockholder
questionnaire and submit it to ANSI with a standard IIN application form
(please see the above link to obtain an application).
The application fee for U.S. and international entities to apply for an IIN block is $1000.00.
Please remember that this is a non-refundable application fee. If your request is approved, you will also be
charged a fee from the ISO/IEC 7812 Registration Authority for each number you
obtain.
The structure of this identification number is as follows:
| Issuer Identification Number |
Individual Account Identification |
Check Digit |
| NNSI |
U.S. Country Code |
Issuer Identifier |
|
|
| 9 |
840 |
(5 digits) |
(variable up to 9 digits) |
1 digit |
Therefore organizations requesting a national IIN will receive an IIN in the
following format:
9 840 XXXXX with XXXXX being assigned by ANSI.
As mentioned above, organizations requesting a National IIN should select
"National Use" in Part A under the section titled "Brief description of card
use."
What if I want to verify an existing IIN or would like a complete listing
of assigned IINs?
The ISO/IEC 7812 Registration Authority (the American Bankers Association)
produces the official record of IIN assignments, the ISO Register of Card
Issuer Identification Numbers.
