The Journey of Customer Identification: A Systematic Literature Review and Directions for Further Investigation

Customer identification has been a key concept in understanding consumers' relationships with brands. In this review article, we aim to provide a comprehensive overview of extant knowledge on customer identification and offer suggestions for future development in line with the gaps identified in the prior literature. We systematically review 73 peer-reviewed journal articles pertinent to customer identification in the Scopus database. We discuss the review findings in five sections, namely, conceptualization, theoretical framework, descriptive information, methodological trends, and key variables. Drawing from the gaps in the existing literature, we propose several suggestions for future research and end the paper with concluding remarks.
