The Metro Journal of Modern Science (MJMS) strongly encourages all authors to register for and use an Open Researcher and Contributor ID (ORCID iD) to ensure accurate author identification, improve research visibility, and strengthen the integrity of scholarly communication.

ORCID provides a unique and persistent digital identifier that:

• Distinguishes researchers from others with similar or identical names.
• Links publications, affiliations, grants, patents, datasets, software, and other research outputs to the correct author.
• Enhances the discoverability, visibility, and credibility of research contributions.
• Supports transparent, reliable, and interoperable scholarly communication across publishers, funding agencies, research institutions, and indexing databases.
• Facilitates accurate attribution of engineering and scientific research throughout a researcher's academic career.

• The Corresponding Author is strongly encouraged to provide a valid ORCID iD during manuscript submission.
• Co-authors are also encouraged to include their ORCID iDs.
• ORCID iDs should be entered in the journal's manuscript submission system and, where applicable, included in the published article.
• Authors are responsible for ensuring that the ORCID iDs provided are accurate and belong to the respective authors.

Authors who do not already have an ORCID iD may register free of charge through the official ORCID registration portal: https://orcid.org/register

Registration takes only a few minutes and provides a lifelong digital identifier that can be used across journals, publishers, funding agencies, and research organizations worldwide.

Where provided, authors’ ORCID iDs will be displayed alongside the published article to ensure accurate author attribution and improve integration with abstracting and indexing databases, digital repositories, institutional research information systems, and scholarly publishing platforms.
