Abstract: Unique device identifier (UDI) is the "identity card （ID）" number of medical device products，and is the universal language of medical devices. The construction of the unique device identification system (UDI System) is the basis for intelligent supervision of medical devices. The full implementation of UDI regulations involves enterprise coding， declaration， UDI coding and verification， data sharing & application etc. Therefore， the stability， clarity and readability of UDI data carrier are very important links for manufacturers， and are the key to the effective implementation of UDI throughout the life cycle of medical devices. In view of this， this research intends to discuss the importance of correct implementation of UDI coding and verification to enterprises by summarizing the “marking” and “identification” of UDI data carrier under the experience of global UDI implementation， so as to provide reference for enterprises on accurate and effective implementation of UDI.
