What Is a Corresponding Author? Roles, Responsibilities, and Journal Rules

Overview

The corresponding author is the person designated to communicate with the journal during the submission and publication process and, in many cases, after publication as well. That is the simplest answer to the question, what is a corresponding author. In journal systems, this person is usually the named contact who submits files, receives editorial emails, responds to reviewer queries, handles proofs, and confirms publication forms or declarations on behalf of the author group.

What the role does not automatically mean is just as important. In many fields, the corresponding author is not necessarily the first author, not always the senior author, and not always the principal investigator. The role is administrative and communicative first, although it may also carry a reputational signal in some disciplines. Because those conventions vary, research teams should not rely on assumptions. They should check the target journal's author instructions and align internally before submission.

In practice, the corresponding author sits at the intersection of authorship, journal submission guidelines, and team coordination. A strong corresponding author keeps the workflow moving, makes sure metadata matches the manuscript, and helps the group avoid mistakes that can lead to technical checks, revision delays, or even a desk rejection. If your team is still selecting a target journal, an acceptance rate guide and an article on indexing signals can help with journal fit, but once a journal is chosen, authorship roles need equal attention.

The safest working definition is this: the corresponding author is the journal-facing contact person who is responsible for accurate submission administration and timely communication, while all listed authors remain responsible for the integrity of the work and the accuracy of authorship information.

Core framework

To use the role confidently, it helps to separate routine tasks from broader accountability. The framework below is useful across many open access journals, subscription journals, and society titles, even though details vary.

1. Before submission: coordination and readiness

Before anything is uploaded, the corresponding author often becomes the project manager for the final pre-submission stage. That usually includes:

• Confirming the final title, abstract, keywords, author order, and affiliations.
• Making sure every author has reviewed and approved the submission version.
• Checking that declarations are complete, including funding, conflicts of interest, ethics statements, data availability, and acknowledgments where required.
• Verifying manuscript formatting against journal submission guidelines.
• Preparing supplementary files, figures, tables, and any required reporting checklists.
• Drafting or assembling the cover letter for journal submission if the journal requests one.

This stage matters because many problems blamed on peer review actually begin with incomplete files, inconsistent metadata, or unclear author approvals. A practical companion here is a preflight process such as the site’s journal submission checklist. Teams also benefit from reviewing manuscript formatting requirements by journal type, since formatting rules often change between article categories.

2. During submission: accurate metadata and declarations

In most submission systems, the corresponding author enters the manuscript metadata manually. This sounds routine, but it is one of the most error-prone parts of the process. Small mismatches can create indexing problems later or trigger editorial queries. Typical duties include:

• Entering all authors exactly as agreed, with correct spelling, institutional names, and email addresses.
• Selecting the article type and subject classifications.
• Uploading the correct version of the manuscript and all associated files.
• Confirming authorship declarations and contributor statements where requested.
• Reviewing whether the journal asks for ORCID identifiers, data repository links, graphical abstracts, highlights, or suggested reviewers.

At this stage, the corresponding author is acting less as a symbolic lead and more as the accuracy gatekeeper. This is one reason the role should go to a reliable person with enough time and access to all records, not simply the most senior name on the paper.

3. During peer review: communication and version control

Once the manuscript is under review, the corresponding author becomes the central channel for editorial communication. That may include acknowledgment of receipt, technical check notices, reviewer comments, revision invitations, deadline reminders, and final decisions. Good corresponding author responsibilities during review usually include:

• Sharing all journal communications promptly with coauthors.
• Keeping a clear record of deadlines and requested changes.
• Coordinating a unified response to reviewers and editors.
• Ensuring revised files are internally approved before resubmission.
• Submitting the response letter and revision package on time.

This communication role is one reason teams should avoid choosing someone who is difficult to reach, likely to change institutions immediately, or not comfortable with the journal’s working language. A delayed response from the corresponding author can slow the whole peer review timeline.

4. After acceptance: proofs, forms, and publication details

Acceptance does not end the role. In fact, some of the most sensitive administrative steps happen after acceptance. The corresponding author may need to:

• Review proofs and coordinate corrections from coauthors.
• Approve author names, affiliations, and acknowledgments for publication.
• Handle licensing or copyright forms.
• Confirm open access selections and article processing charge steps when relevant.
• Check DOI details, supplementary material links, and final publication metadata.

For authors publishing in open access journals, this stage may also involve confirming APC responsibilities with the institution or funder. Even when one person handles communication, financial approval and legal forms should never be assumed without team agreement.

5. After publication: visibility and reader contact

Some journals continue to list the corresponding author as the public contact after publication. Readers, editors, and indexers may direct questions to that person. In some fields, they may receive requests for materials, clarifications, or corrections. This is why the best corresponding author is often someone likely to remain reachable over time.

How the role differs from other journal authorship roles

Confusion often comes from mixing communication roles with contribution roles. A simple distinction helps:

• First author: often the person who contributed most directly to drafting and executing the study, though conventions vary by field.
• Senior or last author: often the supervising or lab-leading author in many disciplines.
• Corresponding author: the main journal contact and submission coordinator.
• Coauthors: contributors who meet the journal’s authorship criteria but are not designated as the primary journal contact.

One person can hold more than one role. For example, a first author can also be the corresponding author, or a senior author can take on both roles. What matters most is that the choice is deliberate and documented.

Practical examples

The role becomes clearer when viewed in real-world team setups. The examples below do not assume one universal rule; they show how the decision can change depending on the project.

Example 1: Graduate student first author with stable supervisor support

A doctoral student writes the paper and leads the analysis. The supervisor reviews the manuscript, advises on journal choice, and has more publishing experience. In this case, either person could be the corresponding author. If the student is organized, available, and likely to monitor email consistently, assigning the student can help them learn the submission process. If the field expects the lab head to handle editorial communication, the supervisor may be a more practical choice. The team should decide based on availability, disciplinary norms, and the journal’s rules rather than hierarchy alone.

Example 2: Large multi-institution collaboration

A paper includes authors from several institutions, with one researcher coordinating the joint writing process. Here, the strongest corresponding author is often the person who can keep records straight and gather approvals efficiently. It may not be the person with the highest rank. In large teams, central coordination matters more than title. The corresponding author should maintain one final source of truth for files, authorship order, supplementary material, and version history.

Example 3: Clinical or case-based manuscript

In clinical writing, confidentiality, ethics wording, and permissions can require careful handling. A clinician involved in the approved submission package may be the best corresponding author, especially if post-publication questions could arise. Teams exploring outlets can also review a focused guide such as best journals for case reports to understand how article type affects submission expectations.

Example 4: Review article led by a subject specialist

For a review article, the corresponding author may be the person best able to handle conceptual queries from the editor and coordinate revisions across coauthors. Since review papers often involve broad synthesis and multiple rounds of refinement, communication skills matter as much as disciplinary authority. A related resource is best journals for review articles by subject area, which can help teams match article type to journal expectations.

Example 5: Early-career researcher changing institutions soon

Suppose the likely first author is finishing a fellowship and expects to move before peer review is complete. Even if that person leads the science, another coauthor with a more stable institutional email may be a safer corresponding author. Since some peer reviewed journals continue to use the corresponding address after publication, long-term reachability matters.

A simple decision checklist for choosing the corresponding author

• Can this person respond quickly throughout submission, review, and proofing?
• Do they understand the manuscript well enough to coordinate revisions accurately?
• Will they remain reachable after publication?
• Are they comfortable checking details such as metadata, declarations, and forms?
• Does the target journal impose any limits or expectations on who can hold the role?
• Have all coauthors agreed on the designation before submission?

If the answer to several of these is no, choose someone else. The role should reduce friction, not create it.

Common mistakes

Many authorship disputes and submission delays come from preventable misunderstandings. These are the most common errors research teams should watch for.

Assuming the corresponding author is automatically the most senior author

Seniority can matter in some fields, but it is not a universal rule. Choosing the most senior person by default can backfire if that person is too busy to respond promptly or prefers not to manage submission systems.

Treating the role as purely ceremonial

The title can look minor until the manuscript enters technical check, revision, or proofing. At that point, the corresponding author responsibilities become operational. If the designated person is disengaged, deadlines can slip quickly.

Failing to align author order, contributor roles, and metadata

One of the easiest ways to create confusion is to have one author list in the manuscript, another in the submission system, and a different assumption in the team. Confirm names, sequence, affiliations, and contact details before uploading anything.

Not reading the target journal’s instructions closely

Some journals allow more than one corresponding author. Others do not. Some require institutional email addresses. Others ask for detailed contributor taxonomies or ethics statements. These differences are exactly why a corresponding-author decision should be linked to the target journal rather than made in the abstract.

Using an email address that may become inactive

Temporary institutional addresses can cause trouble during long review cycles. If the likely contact email may expire, plan ahead and use an address that can be maintained or updated reliably, if the journal allows it.

Submitting before all authors approve the final version

The corresponding author should not become the person who "just uploads it quickly." Submission should happen only after all authors have approved the manuscript, the journal choice, and the author list. Skipping this step risks disputes later and may raise editorial concerns.

Ignoring journal quality checks while focusing only on the role itself

Good communication will not rescue a poor journal choice. Before assigning submission duties, verify that the outlet is legitimate and suitable. A practical resource is how to check if a journal is legitimate, especially if the team is weighing unfamiliar or fast publishing journals.

Overlooking early editorial screens

The corresponding author is often the first to receive a desk-rejection notice. Many early rejections stem from scope mismatch, incomplete files, or weak positioning rather than from fatal scientific flaws. Reviewing common desk rejection reasons can help the team strengthen the submission before it reaches that point.

When to revisit

The corresponding author decision should be revisited whenever the submission process, team structure, or journal rules change. This is not a one-time label that can be assigned without review. It is a practical role that should fit the current manuscript and the current journal.

Revisit the decision in these situations:

• When the target journal changes: A new journal may have different author instructions, contributor requirements, or proof workflows.
• When the team composition changes: If an author joins, leaves, changes affiliation, or becomes unavailable, the communication plan may need to change too.
• When the manuscript type changes: A case report, review article, data paper, or short communication may come with different submission expectations.
• When new tools or standards appear: Submission platforms, ORCID integration, contributor taxonomies, data-sharing requirements, and proofing systems can all alter the practical demands of the role.
• When the likely contact person is moving institutions: Long review cycles make future availability important.
• When the project becomes more complex: Multi-site studies, external funding, ethics approvals, or open access licensing steps can increase the need for a highly organized corresponding author.

To keep the process smooth, use this action-oriented review routine before every submission:

1. Confirm the target journal and read its latest author instructions.
2. Agree on author order, affiliations, and the corresponding author in writing.
3. Check whether one or multiple corresponding authors are permitted.
4. Verify the contact email and long-term availability of the designated person.
5. Prepare all declarations, forms, and supplementary files before opening the submission system.
6. Run a final metadata check so the manuscript file matches the portal entries exactly.
7. Decide how editorial messages will be shared with coauthors during review.

If your team follows that routine, the corresponding author role becomes much easier to manage. The point is not to elevate one author above the others. It is to make sure one clearly designated person can move the manuscript through the journal process without confusion, delay, or preventable administrative errors.

In other words, the best answer to what is a corresponding author is practical rather than ceremonial: it is the author your team trusts to represent the manuscript accurately, communicate reliably, and keep the publication process organized from submission to publication and beyond.
