Standard numbers or codes published on an item that cannot be accommodated in another field (field 020, field 022, or field 027, etc.). Use the 1st indicator or subfield ‡2 to indicate the type of number or code.
|ISRC - International Standard Recording Code|| |
The ISRC usually appears on an item preceded by the letters ISRC. It consists of 12 alphanumeric characters structured as four elements separated by hyphens:
The country code is from ISO 3166, Codes for the Representation of Names of Countries (http://www.iso.org/iso/home/standards/country_codes.htm). The first owner is alphanumeric and consists of three characters. The year of recording code consists of the last two digits of the year (e.g., 82 for 19 82). The recording code consists of five digits, assigned sequentially by the first owner.
Do not enter the initials ISRC or the hypens between numbers. Use 1st indicator value 0 .
|UPC - Universal Product Code|| |
The UPC appears as a barcode symbol with 12 digits printed below it. Hyphens or spaces usually separate the elements of the number on the item. The code has three basic parts:
For audio and video products, the ten digits of part 2, printed below the parallel bars, consist of three elements: a five-digit code that designates the manufacturer assigned by the Uniform Code Council; a five-digit selection number; and a single digit configuration number. The fifth digit of the first element serves as both the last digit of the manufacturer designation and the first digit of the selection number. The tenth digit (configuration number) indicates the format of the product.
For serials, the five digits after the NSC identify the publisher or distributor. The next five digits encode a BIPAD title identification number that uniquely identifies each publication. A two-character supplemental symbol designating a specific issue may follow the number.
For paperback books, there are two bar-coding structures. In one barcode structure, the ten digits of part 2 may consist of a five-digit identifier for the publisher. The next five digits contain the title portion of the ISBN.
For the other barcode structure, the first five digits of part 2 identify the publisher or the bookline, the next five digits represent a cover price or price category. Five add-on digits may follow part 3. They are derived from the title portion of the ISBN.
Enter the UPC without spaces or hyphens. Use 1st indicator value 1.
|ISMN - International Standard Music Number|| |
ISMN is an agency-assigned data element. ISMNs are assigned to music publications by designated agencies in each country participating in the program.
An ISMN consists of ten or thirteen digits. The 10-digit ISMN, used before 2008, is comprised of the letter M followed by 8 digits (variable length publisher number plus item number) plus a single character check digit. The check digit applies to the previous 8 digits.
The 13-digit ISMN, used since 2008, has the prefix 979 and a 0 to replace the M, then 8 digits plus the final check digit. The check digit applies to the previous 12 digits. A 13 digit ISMN is identical to the EAN-13 number encoded in the bar code. The structure is specified in ISO 10957.
An ISMN usually appears on an item preceded by the initialism ISMN and with functional parts separated by a hyphen or space.
Enter the ISMN without spaces or hyphens. Use 1st indicator value 2.
|EAN - International Article Number|| |
The EAN has 13 digits. The first three digits are the EAN Prefix, representing a country or region or a broad class of materials such as serials or paperback books. The next nine digits comprise the company prefix and the item number. An all-numeric Modulus-10 check digit is the 13th character of the EAN. Enter the EAN without the hyphens or spaces. Use 1st indicator value 3.
For serials, a three-digit prefix (977) is used in combination with the eight-digit International Standard Serial Number (ISSN) or with a nationally administered title number such as the BIPAD number in North America. A two- or five-digit add-on symbol to designate issues may be present.
For paperback books, a three-digit prefix (978) is followed by the first nine characters of the International Standard Book Number (ISBN), omitting the final ISBN check character. A five-digit supplement may be used to code additional data, e.g., price.
Enter the EAN without the hyphens or spaces. Use 1st indicator value 3.
For EAN 9 780838 934326 90000 enter:

|SICI - Serial Item and Contribution Identifier|| |
The SICI is a variable length code that provides unique identification of serial issues (SICI) and serial contributions (SCI). The SICI consists of the ISSN, issue date, issue numbering, SICI standard version number and a check character. The SCI adds the contribution location and a title code (if more than one title begins on a page) between the issue numbering and the SICI version number. The barcode version differs from the eye-readable version.
Enter SICI numbers with punctuation separating the sections of the identifier as found in the number. Use 1st indicator value 4.
For the SICI above, enter:
|Type of standard number or code. The type of standard code in the field.|
|Difference indicator. The difference between a scanned number or code and the same number or code in eye-readable form.|
|‡a Standard number or code||The standard code or number. |
|‡c Terms of availability||Price information or statements of availability. Use for qualifying information about the item. |
|‡d Additional codes following the standard code||Optional digits (e.g., manufacturer's price information). Usually such digits are to the right of the code. |
|‡z Canceled/invalid standard code||A canceled or invalid code. |
|‡2 Source of number or code||Codes for the source of the number or code. Use with 1st indicator value 7. See the Standard Identifier Source Codes (http://www.loc.gov/standards/sourcelist/standard-identifier.html). |
|Field 024 does not print.|
