The article examines the digital transformation of public services in Kazakhstan through the lens of Digital Public Infrastructure (DPI) and citizen-centred project management. The purpose of the study is to develop a methodological justification for modernising the issuance and replacement of the national identity card as a priority case for moving from e-government to a proactive, secure and integrated digital state model. The methodology combines a review of international literature published in 2020-2026, analysis of regulatory and policy documents, a comparative review of Estonia’s experience, service mapping, a service prioritisation matrix, and As-Is/To-Be process modelling. The originality of the study lies in integrating three analytical frameworks: a whole-of-government approach, the DPI/GovStack architecture, and a cost/benefit matrix for selecting a digital transformation quick win. The findings show that the national ID issuance and replacement service has high transformational potential, as it relies on existing DPI components in Kazakhstan, including eGov.kz, eGov Mobile, digital identity, e-signature, payment services and inter-agency data exchange. At the same time, sustainable impact requires legal and organisational safeguards: biometric data governance, algorithmic audit, transparent logs, independent cybersecurity monitoring, preservation of alternative offline channels and systematic development of digital competencies among civil servants.
