DOI

What is a DOI?

A Digital Object Identifier (DOI) is a unique alphanumeric code assigned to digital publications, ensuring a permanent and reliable link to the content online. All DOIs assigned by IJCTECE are registered with CrossRef, making them easily citable and accessible within academic and research communities.

Structure of a DOI

A DOI consists of two main parts: the prefix and the suffix, separated by a forward slash (/).

Example:

DOI: 10.15680/IJCTECE.2025.0804001

Prefix – 10.15680

· The prefix is assigned by the registration agency (e.g., CrossRef).

· It identifies the publisher or journal.

· 10 is the directory indicator for DOIs.

· 15680 is the unique code for the publisher (in this case, IJCTECE’s publisher).

Suffix – IJCTECE.2025.0804001

· The suffix is created by the publisher.

· It typically includes:

  Journal abbreviation (e.g., IJCTECE)

 Year of publication (e.g., 2025)

 Volume and issue number (e.g., 08, 04)

 Unique article number (e.g., 001)

Together, the prefix and suffix form a globally unique identifier for each article.

Why is a DOI Important?

· Permanence: It always points to the article, even if the hosting URL changes.

· Citations: Preferred in scholarly citation styles (APA, MLA, IEEE, etc.).

· Searchability: Makes content easier to find in digital databases and indexes.

· Credibility: Shows that the article is formally published and registered.
