Trademark code is a code composed of numbers and letters, which only exists in the Trademark Office database. This code is used to classify, manage and search trademarks. Each trademark has a unique trademark code. Trademark coding can help the Trademark Office manage trademarks more efficiently, while also providing more convenience to trademark holders.

Trademark codes are determined by the classification of the trademark. Trademark classification is divided according to the category to which the trademark belongs, and generally includes two categories: goods and services. Trademark coding adopts an internationally accepted classification system, which provides a unified standard for global trademark management. Therefore, the role of trademark coding is to uniformly classify and identify trademarks to facilitate trademark review and inquiries during trademark transactions.

The generation of trademark codes is based on the trademark name, trademark classification and some descriptive information. The trademark code can be up to 7 or 10 digits in length and is expressed in a combination of letters and numbers. Trademark coding can not only help trademark examiners more efficiently determine whether a trademark has been registered, but also help the general public understand the basic information about a trademark. Therefore, trademark coding is an indispensable and important part of the trademark management and commercial transaction process.
