How to list certifications on a resume: format, placement and examples

The line format, field by field

Every certification line carries the same pieces of information, in this order:

1. The full official name, spelled the way the issuer spells it on your certificate.
2. The abbreviation in brackets, where the issuer uses one (CCNA, PMP, CySA+, CISSP).
3. The issuing organisation.
4. The month and year you earned it, plus the expiry month if the issuer sets one.
5. A credential ID, validation number or verification link.

Written out, two real lines look like this:

• AWS Certified Solutions Architect - Associate, Amazon Web Services, March 2026 (valid to March 2029). Validation number available on request.
• CompTIA Security+ ce, CompTIA, June 2026 (valid to June 2029). Verify: credly.com/badges/your-badge-id

The expiry dates are not decoration. AWS certifications are valid for three years, and CompTIA's renewal policy says A+, Network+, Security+ and the other certifications in its continuing education program expire three years from the certification date. CompTIA marks those certifications with a "ce" designation, which is why the second line carries it.

The proof field is where most people go wrong, by leaving it out. AWS gives every certified person a 16-character alphanumeric validation number, printed on the PDF certificate in your AWS Certification Account, which anyone you share it with can check at aws.amazon.com/verification. CompTIA, AWS and many other issuers also publish digital badges through Credly, and the badge URL is a one-click check. Credly itself notes that it does not issue credential IDs, so for a Credly badge the link is the proof. How and when employers run these checks is covered in do employers verify certifications; the resume's only job is to make the check easy.

If space is tight, drop the word "valid" and keep the dates: "CompTIA Security+ ce | CompTIA | Jun 2026 to Jun 2029". Never drop the issuer. "Security+" alone reads like a skill claim, while "CompTIA Security+" reads like a credential.

Where the certifications section goes

Use a separate section with a plain heading: Certifications, or Licenses and Certifications if you hold a professional licence. Parsing software and tired humans both look for plain headings.

Where that section sits depends on what the certification is doing for you.

• If the certification is the main reason you qualify, put the section directly under your summary, above experience. That covers career changers, new graduates and anyone applying for a first IT, cloud or security role.
• If you already have relevant experience, lead with experience and put certifications after it, beside or above education. A network engineer with four years on the job is hired for the four years, and the CCNA confirms them.
• In both cases, name your most relevant certification once in the summary, attached to something you did with it: "Service desk analyst with CompTIA A+ and Network+, two years handling a retail chain's in-store tech issues."

The name line is a different matter. Post-nominal letters belong to professions that use them as a convention. PMI's trademark guidelines give the form "Joseph Smith, PMP" for business cards and email signature blocks, and add that anyone whose PMI certification has lapsed should stop using the credential immediately. Nursing has a formal order: the American Nurses Credentialing Center lists highest earned degree, then licensure, then state designations, then national certifications, then awards and honours, then other recognition, so a new graduate writes "Maria Lopez, BSN, RN". For entry-level IT certifications, leave your name alone. "Jane Doe, A+, Network+" is not a convention any IT employer expects, and it pushes your contact details off the first line. Let the section and the summary carry those.

Ordering several certifications, including CompTIA stacks

Order by relevance to the job first and by date second. A SOC analyst posting that asks for Security+ should see Security+ on the first line, even if you earned AWS Cloud Practitioner more recently. Alphabetical order helps nobody.

CompTIA adds a wrinkle. It groups certain combinations into stackable certifications that carry their own names and Credly badges. A+ and Network+ together make CompTIA IT Operations Specialist (CIOS). A+, Network+ and Security+ together make CompTIA Secure Infrastructure Specialist (CSIS). CompTIA describes its Specialist tier as aimed at early-career IT professionals with 0 to 2 years of experience. The way to list a stack is to put the stack name first and the component certifications on the lines beneath it:

• CompTIA Secure Infrastructure Specialist (CSIS), CompTIA, July 2026
• CompTIA Security+ ce, CompTIA, July 2026
• CompTIA Network+ ce, CompTIA, February 2026
• CompTIA A+ ce, CompTIA, August 2025

Do not list the stack alone. Postings ask for "Security+" and "Network+", rarely for "CSIS", and a recruiter searching your resume for Security+ needs to find the string.

Foundational certifications that a higher one has overtaken can usually go. If you hold AWS Certified Solutions Architect - Associate, AWS Certified Cloud Practitioner adds little for a cloud role; keep it only if you have room and nothing better to fill it. The same logic applies to Azure Fundamentals once you hold Azure Administrator Associate.

Certifications you are still working on

List an unfinished certification only when the exam is booked. A date turns "studying for" into a commitment a recruiter can plan around; without one, it reads as an intention. Use a format that cannot be mistaken for an earned credential:

• CompTIA Security+, CompTIA, exam scheduled November 2026
• AWS Certified Solutions Architect - Associate, Amazon Web Services, expected December 2026

Never put an in-progress credential after your name, in your headline or in the summary as if it were held. Expect the interview question and have a specific answer: the date, and how your last practice exam went. The day you pass, update the line and email any recruiter who has your resume. A pass in the middle of a hiring process is a reason to get back in touch.

If you fail, change the line before you send another application. "Exam scheduled November 2026" on a resume dated December tells the reader exactly what happened.

New nurses face the same situation with the licence exam. Write the status plainly ("NCLEX-RN scheduled January 2027") and see after passing the NCLEX for what changes once the licence is issued.

Expired and lapsed certifications

A lapsed certification is not a current certification, and the resume must not suggest otherwise. CompTIA's policy is blunt: if you do not renew within the three-year cycle, you have to pass the latest exam version to be certified again. AWS certifications run three years and must be active to renew. PMI tells lapsed holders to stop using the credential.

You have three honest options:

• Leave it off. This is the right choice when the credential is old, unrelated, or overtaken by something newer.
• List it with dates that show it has lapsed: "CompTIA Network+, CompTIA, earned 2019 (expired 2022)". Do this when the history matters, for example when you are returning to IT after years away and want to show you once worked at that level.
• Renew it before you apply. If the posting names the credential as required, a lapsed one will not satisfy it, and renewal is usually faster than the job search.

One exception catches people out. CompTIA introduced its continuing education renewal program on 1 January 2011, and it still issues badges for Good-for-Life (GFL) versions of A+, Network+ and Security+. If yours is a GFL certification, write "CompTIA A+ (Good for Life)" so nobody mistakes the old date for a lapse.

Matching the posting's wording, both ways

Recruiters search their applicant database with whatever string the hiring manager gave them, which is sometimes the abbreviation and sometimes the full name. Write both, once each, so either search finds you: "Certified Information Systems Security Professional (CISSP)", "Cisco Certified Network Associate (CCNA)". Do certifications help you get past resume screening explains how those searches work and why naming the exact credential is the one place keywords reliably matter.

Check the posting's version of the name against the issuer's. A posting that says "AWS Solutions Architect certification" is asking for AWS Certified Solutions Architect - Associate or Professional, and your line should use the official title so the match is unambiguous. When an issuer renames a credential, list the name printed on your certificate. AWS, for example, now lists AWS Certified CloudOps Engineer - Associate alongside AWS Certified SysOps Administrator - Associate on its recertification page, and a SysOps holder should keep the SysOps title rather than claim the new one.

Then back the line up elsewhere. A certification line proves you passed an exam. The experience or projects section proves you can use what it covers. If your AWS line sits next to a project bullet that names the services you configured, the two support each other; cloud projects for your resume covers what to build. Never add a certification you do not hold to catch a keyword search, even phrased as "Security+ knowledge". It is the easiest claim on the page for an employer to check.

What to leave off

A certificate of completion is not a certification, and listing one under Certifications next to real credentials looks like padding at best. A Udemy course called "AWS Solutions Architect" is training for the AWS exam, not the AWS credential. Put courses in a separate section headed Training or Professional Development, with the provider and the month: "AWS Solutions Architect Associate exam prep course, Udemy, January 2026". Professional certificate programs such as Google's IT Support Professional Certificate on Coursera can go in either section, as long as you write the program's exact name so nobody reads it as a vendor certification.

Leave out logos and badge images. Parsing software skips images, they break the layout of plain-text versions of your resume, and some issuers restrict their use. PMI's guidelines allow PMP holders in good standing to use the PMP logo only on business cards or in an electronic signature block next to the holder's name. A text line with a verification link does everything the logo would.

Also leave off exam scores, certifications unrelated to the target job, and anything you cannot verify on request.

Four worked examples

Each example is a complete Certifications section plus the summary sentence that points to it. Swap in your own details.

Summary sentence: "Former logistics coordinator moving into cloud support, AWS Certified Solutions Architect - Associate, with a documented three-tier web application built on AWS."

• AWS Certified Solutions Architect - Associate, Amazon Web Services, March 2026 (valid to March 2029). Badge: credly.com/badges/your-badge-id
• AWS Certified Cloud Practitioner, Amazon Web Services, November 2025

Place the section above experience, because the logistics job is context and the AWS credential is the qualification. More on the role itself in getting a job after an AWS certification.

Summary sentence: "Help desk technician with CompTIA Security+, Network+ and A+, eighteen months resolving access and endpoint tickets for a 400-person firm."

• CompTIA Secure Infrastructure Specialist (CSIS), CompTIA, July 2026
• CompTIA Security+ ce, CompTIA, July 2026 (valid to July 2029)
• CompTIA Network+ ce, CompTIA, February 2026
• CompTIA A+ ce, CompTIA, August 2025
• CompTIA Cybersecurity Analyst (CySA+), CompTIA, exam scheduled December 2026

Experience goes first here, because eighteen months of tickets is the strongest thing on the page.

Name line: "Jane Doe, PMP".

• Project Management Professional (PMP), Project Management Institute, May 2024. PMI certification number available on request.
• Certified ScrumMaster (CSM), Scrum Alliance, October 2023

The post-nominal is appropriate because PMI's own guidelines show the form. Write it as "PMP certification" or "PMP credential" in sentences, since PMI discourages using the mark as a bare noun or plural.

Name line: "Maria Lopez, BSN, RN".

• Registered Nurse (RN), Texas Board of Nursing, licensed August 2026, active
• Basic Life Support (BLS) Provider, American Heart Association, May 2026 (renewal due on the month printed on your card)
• Advanced Cardiovascular Life Support (ACLS), American Heart Association, scheduled January 2027

The section heading here is Licenses and Certifications, and the licence goes first. ANCC's guidance is to list national nursing certifications after licensure and non-nursing certifications last. Employers check RN licences through Nursys, the national licensure database run by NCSBN, so the application form, not the resume, is where the licence number goes.
