Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www.iso.org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 68, Financial services, Subcommittee SC 8,

Reference data for financial services.

This second edition cancels and replaces the first edition (ISO 13616-1:2007), of which it constitutes a

minor revision with the following changes:

— To evolve together with regulation, Clause 5 a) has been corrected from “the first two letters (2!a)

shall always be the two-character country code (alpha-2 code), as defined in ISO 3166-1, of the

country in which the financial institution servicing the account resides” to “the first two letters

(2!a) shall always be the two-character country code (alpha-2 code), as defined in ISO 3166-1, of the

country in which the financial institution services the account”.

— In 6.3, the following note clarifies how to implement ISO/IEC 7064 check digit, to ensure proper

validation of the IBAN: “From this, the check digits can only be in the range [02..98].”.

Attention is further drawn to the Introduction of this document, in which the expression “this revision”

refers to ISO 13616-1:2007.

0 Introduction
0.1 General

The use of electronic communication media and services internationally for the cross-border

transmission of information and payment and payment-related transactions between financial

institutions, as well as between financial institutions and their customers, continues to increase.

In order to facilitate automated processes in support of straight through processing (STP) in this

environment, the ISO 13616 series has been developed by ISO/TC 68/SC 7 as a means by which financial

institutions and their customers can exchange customer account identification details in a machine-

readable form through inter-industry electronic data interchange (EDI). It also makes provision for

validation of the information provided.

In developing the ISO 13616 series, it was recognized that a single, universal method for identifying the

account and banking relationship for customers of financial institutions was not practical. Accordingly,

the ISO 13616 series recognizes that financial institutions would wish to retain, wherever possible, their

current national identification methods. It therefore provides a method whereby a minimum amount

of change to existing systems is required and, at the same time, proposes a means of structuring the

information in a way that promotes automated processing of the information provided.

It is anticipated that the use of the ISO 13616 series in electronic data interchange will:

a) reduce the need for manual intervention in the processing of inter-industry and intra-industry data

interchange,

b) improve the level of confidence in the accuracy of the information provided, and

c) provide certainty that the information provided is relevant to the country of ownership of the

account.

It is recognized that the international bank account number (IBAN) could also be of use in a paper

environment. The use of information to further qualify details of the financial institution to which the

IBAN applies is not precluded by their use outside of the IBAN.

Nationally agreed IBAN formats that are compliant with the ISO 13616 series, and subsequently

registered with the ISO 13616 Registration Authority, are available at https://www.iso9362.

0.2 Background to this revision of ISO 13616

This revision of ISO 13616 was requested to achieve alignment between the ISO IBAN standard and the

IBAN standard of the European Committee for Banking Standards (ECBS), in order to have one single

globally accepted standard.

This revision of ISO 13616 incorporates the experience gained in the many European countries that

have already implemented the IBAN based on the ECBS standard. The critical advantages compared

with the previous ISO IBAN standard are the requirement for a fixed length of the IBAN, as well as

a fixed length and position of the bank identifier within the IBAN. This enables plausibility checks,

resulting in better STP and improved cost efficiency.
