Based on the Technical Instructions, since April 25, 2022, electronic land certificate checking registration services have been implemented simultaneously in all Land Offices in Indonesia. The author formulates the problem as follows: First, How is the accuracy of electronic land certificate checking at the South Jakarta Administrative City Land Office? Second, What are the obstacles faced in electronic land certificate checking at the South Jakarta Administrative City Land Office? The type of research used is normative legal research with documentary studies using secondary data and qualitative data analysis techniques and interviews were conducted with parties directly related to this research. Based on the results of the research that has been carried out, it can be concluded that: First, That IT-based services are very much needed at this time to support the problem of electronically integrated systems and accelerate services to the public. So that the effectiveness of government services can be maximized. However, in practice, inaccuracies are still found in the results of electronic land certificate checking in one day of registration with a volume of incoming files between 100 to 150 applications with an accuracy ratio of 90% and inaccuracies of 10%. This is caused by the certificate not being validated at the beginning by human error and the data not being updated at the Data and Information Center on the BPN Central server which results in inaccurate land certificate checking results in the final results of the issuance of the check. Second, the obstacles faced by users of electronic land certificate checking services, namely PPAT and BPN, are basically mostly related to the IT system and server of the Electronic Land Certificate Checking Registration Service. Users of the Electronic Land Certificate Checking Registration Service must be skilled and adequate in using all the devices needed to complete the certificate checking registration.
