Radio frequency identification of animals — Code structure

This International Standard specifies the structure of the radio-frequency (RF) identification code for animals. RF identification of animals requires that the bits transmitted by a transponder are interpretable by a transceiver. Usually, the bit stream contains data bits, defining the identification code and a number of bits to ensure correct reception of the data bits. This International Standard specifies the structure of the identification code. This International Standard does not specify the characteristics of the transmission protocols between transponder and transceiver. These characteristics are the subject of IS0 11785. The structure may include a manufacturer’s code, the granting and use of a manufacturer’s code are the subject of ISO 24631.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

manufacturer code) based on ISO24631-1 and issues and registers manufacturer and product codes
4 Description of code structure
The code in the transponder is split up into several code fields, each with its own meaning. Each field is coded in
natural binary with the high-order bit being leftmost. The structure of the code shall be as specified in Table 1.
Bit number 1 in the code is the most significant bit (MSB); bit number 64 is the least significant bit (LSB).
The combination of CC and national identification code provides a unique worldwide identification number.

For applications which require the retagging of animals with the same identification number and for the
storage of user-defined information in the transponder, the reserved field in ISO 11784 is split into three
different code fields. See Table 1.
The code structure shall include a country code or a manufacturer’s code; the granting and use of a
manufacturer’s code are the subject of ISO 24631-1.
Conditions for using the ISO 11784 coding that shall be respected are listed in Annex A.
Table 1 — Code structure
Bit No Information Combinations Description
1 Flag for animal (1) or non-animal 2 This bit signals whether the transponder is
a
(0) used for animal identification or not. In all ani-
mal applications this bit shall be 1.
e
2-4 Retagging counter 8 This counter shall be used only if a retagging
with the same identification number is decided
by the specific country (bits 17-26). This coun-
ter shall be set to zero for the first assign of a
transponder to an animal. If further assigns of
new transponders because of loss or malfunc-
tion to the same animal are necessary, then the
identification number shall be the same, but the
counter shall be incremented by one.
b, e
5-9 User information field 32 The content of this field is informative. It is de-
fined by the country, as coded in the CC field.
e
10-11 Reserved field 32 The value of these bits shall be set to “0”.
a
The method to distinguish between animal and non-animal applications using bit No. 1 allows the code structure to be
recognized electronically. However, this requires that future standards on RF identification in other fields will adhere to this
convention.
