This section specifies the correspondence between EPCs and GS1 keys.The correspondence between EPCs and GS1 keys relies on identifying the portion of aGS1 key that is the GS1 Company Prefix. The GS1 Company Prefix is a 6- to 11-digitnumber assigned by a GS1 Member Organization to a managing entity, and the managingentity is free to create GS1 keys using that GS1 Company Prefix.In some instances, a GS1 Member Organization assigns a “one off” GS1 key, such as acomplete GTIN, GLN, or other key, to a subscribing organization. In such cases, theGS1 Member Organization holds the GS1 Company Prefix, and therefore is responsiblefor identifying the number of digits that are to occupy the GS1 Company Prefix positionwithin the EPC. The organization receiving the one-off key should consult with its GS1Member Organization to determine the appropriate number of digits to ascribe to theCompany Prefix portion when constructing a corresponding EPC. In particular, asubscribing organization must not assume that the entire one-off key will occupy theCompany Prefix digits of the EPC, unless specifically instructed by the GS1 MemberOrganization issuing the key. Moreover, a subscribing organization must not use thedigits comprising a particular one-off key to construct any other kind of GS1 Key. Forexample, if a subscribing organization is issued a one-off GLN, it must not create SSCCsusing the 12 digits of the one-off GLN as though it were a 12-digit GS1 Company Prefix.When derived from GS1 Keys, the “first component of an EPC” is usually, but notalways (e.g., GTIN-8, One-Off Key), a GS1 Company prefix. The GTIN-8 requiresspecial treatment; see Section 7.1.2 for how an EPC is constructed from a GTIN-8. Asstated above, the One-Off Key may or may not be used in its entirety as the firstcomponent of an EPC.7.1 Serialized Global Trade Item Number (SGTIN)The SGTIN EPC (Section 6.3.1) does not correspond directly to any GS1 key, but insteadcorresponds to a combination of a GTIN key plus a serial number. The serial number inthe SGTIN is defined to be equivalent to AI 21 in the GS1 General Specifications.The correspondence between the SGTIN EPC URI and a GS1 element string consistingof a GTIN key (AI 01) and a serial number (AI 21) is depicted graphically below:Copyright ©2005- 2011 GS1 AISBL, All Rights Reserved.
