Appendix A of this standard is an informative appendix
This standard is proposed by the China Standards Research Center. This standard is under the jurisdiction of the China Standards Research Center. Foreword
According to the authorization of the administrative department of standardization of the State Council, this standard is organized and implemented by the National Unified Code Management Center for Products and Services, and it is the maintenance organization of the unified code (set) for products and services nationwide. Any product manufacturer and service provider may submit an application for product and service coding to the maintenance organization (or its branches and agents).

1 Scope
National Product and Service Unified Code Compilation Rules GB 18937—2003
This standard specifies the rules for compiling the unified national product and service code so that each product and service circulating in the market has a unique and unchanging code.
This standard applies to the compilation of the unified national product and service code, and also applies to information processing and information exchange related to the production, storage, transportation, sales, quality service, management, etc. of products and services. 2 Normative references
The provisions of the following documents become the provisions of this standard through reference in this standard. For any dated referenced document, all subsequent amendments (excluding errata) or revisions are not applicable to this standard. However, the parties to the agreement reached based on this standard are encouraged to study whether the latest versions of these documents can be used. It is an undated reference document, and its latest version applies to this standard. GB/T19000 Quality Management System Fundamentals and Vocabulary (GB/T19000--2000, idtISO9000:2000) 3 Definition of the connotation of products and services
www.bzxz.net3.1 According to the definition of GB/T19000, product refers to the result of a group of interrelated or interacting activities that transform input into output.
Note: There are four common product categories: services (such as transportation), software (such as computer programs, databases), hardware (such as engine mechanical parts, electronic components), and process materials (such as lubricants). Among them: (1) Services are usually intangible and are the result of at least one activity that needs to be completed at the interface between the supplier and the customer. Results. The provision of services may involve activities such as:
Activities performed on tangible products provided by the customer (such as repairing a car); activities performed on intangible products provided by the customer (such as preparing a tax return based on an income statement); delivery of intangible products (such as teaching);
Creating an atmosphere for the customer (such as the layout of a hotel environment) (2) Software consists of information, is usually an intangible product, and can exist in the form of methods, papers or programs. (3) Hardware is usually a tangible product, and its quantity has the characteristic of being countable. (4) Process materials are usually tangible products, and their quantity has the characteristic of being continuous. Hardware and process materials are usually referred to as goods. 3.2 In order to facilitate the understanding, promotion and application of factories, this standard decomposes the products in GB/T19000 into products and services. Service, specifically refers to a single item or service with a specific name, specification, packaging, etc. produced or provided by an organization. 4 Code structure and representation
4.1 Code structure
4.1.1 The national unified product and service code consists of a 13-digit main body code and a 1-digit check code. 4.1.2 The main body code adopts a series sequential code or sequential code, and is uniformly allocated, maintained and managed by the "National Product and Service Unified Code Management Center", a maintenance organization authorized by the standardization administrative department of the State Council. 4.1.3 The check code is used to verify the correctness of the main body code, and its calculation method is as follows: Step 1: Determine the code position number of each digit in the code including the check code in order from left to right (the check code is 189
GB 18937--2003
The code position number is 1, and the others from right to left are 2, 3, ………, 14); Step 2: Starting from the code position number 2, find the sum of all even-numbered codes: Step 3: Multiply the sum of the second step by 3:
Step 4: Starting from the code position number 3, find the sum of all odd-numbered codes except the code position number 1; Step 4: Add the results of the third and fourth steps; Step 6: If the unit digit of the sum obtained in the fifth step is zero, the check code is 0; if the unit digit of the sum obtained in the fifth step is not zero, subtract the unit digit of the sum obtained in the fifth step from "10", and the difference is the check code. 4.2 Code representation
The national unified product and service code is composed of the main code and the check code connected in sequence without leaving any spaces. Its representation is shown in Figure 1: XXXXXXXXXXXXXX

Example of calculating the check code
GB 18937—2003
Taking the calculation of the check code of the main code 8358210987461 as an example, Table A.1 gives the relationship between the check code and the main code, code position number, even digits and odd digits in this example. Check code calculation example

Even digit
Odd digit
The check code calculation steps in this example are as follows:(1) 1+4+8+0+2+5+8=28;
(2) 28X3-84;
(3) 6+7+9+1+8+3-34;
(4) )84+34-118;
(5) 10-82
Therefore, the check code in this example is 2, that is, the value of X in the table is 2.0
