The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 21 May 2021 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 December 2021. Classification: ICS 35.040, CCS A24. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Document specifies the encoding, bar code representation and application of the global location number. This Document is applicable to the identification of the global location, automatic identification and data capture, and electronic data sharing, etc.

Appendix A

(Normative) Calculation Method of the Check Code A.1 Calculation method The check code uses 10 as the modulus, 3 and 1 as the weighting factors, and is calculated according to the following steps:

--- Step 1: Number the 13 digits (including the check code) sequentially from right to left, starting from 1;

--- Step 2: Add up the values at all positions with even numbers;

--- Step 3: multiply the result of the Step-2 by the value 3;

--- Step 4: Starting from the sequence number 3, add up the values at all positions with odd sequence numbers;

--- Step 5: Add up the result of the Step-3 to the result of the Step-4;
