The Technical Journal of the Faculty of Engineering of the University of Zulia with the purpose of guaranteeing permanent access to the articles, through the registration, tracking and constant monitoring of metadata, both its articles, as well as the numbers published from the year 2020 to the current number, have a DOI (Digital Object Identifier). Each DOI identifier is generated by Crossref through the OJS (Open Journal Systems) manager. To ensure its operation, the DOI is always displayed as a full URL link, both in the presentation of articles and journal numbers, as well as in PDF files and currently in HTML. 

As of 2021, the identifier for authors and researchers ORCID ID (Open Research and Contributor ID) is mandatory for the registration of authors. It is a persistent identifier that distinguishes authors from other researchers, makes it easier to recognize their contributions, links them to their institution, and reduces the chances of errors in their registration. It is a totally free service.
