See 5.2 for the encoded data structure; 5.3 for the unified national website data structure; 5.4 for the vendor-defined website data structure. 5.2 Encoded data structure 5.2.1 Composition of encoded data structure The encoded data structure shall consist of one or more element strings taken from Table 1 in sequence. Each element string shall consist of a GS1 application identifier (AI) and a GS1 application identifier (AI) data field. The GS1 application identifier and GS1 application identifier data fields for the extended data item are taken from Table A.1 in Annex A. Among them, the GTIN element string is required, and others are optional. See C.1 and C.2 of Annex C for examples of the two dimensional code for commodity of encoded data structures.   Table 1 Element string of two dimensional code for commodity Name of element string GS1 application identifier (AI) Format of GS1 application identifier (AI) data field Optional/required Global trade item number (GTIN) 01 N14 a Required Batch or lot number 10 X..20 b Optional Serial number 21 X..20 Optional Expiration date (YYMMDD) 17 N6 Optional Extended data item c AI (see Table A.1) Format of corresponding AI data field Optional Extended packaging URL 8200 Follow the provisions of RFC1738 protocol on URL Optional a N: numeric character, N14: 14 numeric characters, with fixed length. b X: Any character in Table B.1 in Annex B, X..20: maximum of 20 arbitrary characters in Table B.1, with variable length. c Extended data items: users can select 1 to 3 element strings from Table A.1 to represent other extended information of products. 5.2.2 Global trade item number (GTIN) element string The GTIN element string shall consist of the GS1 application identifier "01" and its corresponding data field of the application identifier, which shall appear as the first element string. The GTIN data field shall consist of 14-digit codes, including packaging indicator, vendor identification code, item code and check code, see reference [1] in Bibliography. See GB 12904 for the allocation and calculation of vendor identification code, item code and check code. 5.2.3 Batch or lot number element string The batch or lot number element string shall consist of the GS1 application identifier "10" and the batch or lot number data field for commodity. The batch or lot number data field is a vendor-defined alphanumeric string, with variable length, up to 20 bytes, including all the characters in Table B.1. 5.2.4 Serial number element string The serial number element string shall consist of the GS1 application identifier "21" and the serial number data field for commodity. The serial number data field is a vendor-defined alphanumeric string, with variable length, up to 20 bytes, including all the characters in Table B.1.
