How to Register with EPSO: Your First Steps to an EU Career (Beginner's Guide)

So you want to work for the EU — where on earth do you start?

If you've just discovered that you can build a career inside the European institutions, the first thing you hit is a wall of acronyms: EPSO, EU Login, AD5, CAST, FG IV, NoC... It feels like you need a decoder ring before you can even sign up.

You don't. The actual first step is simple: create your account. Everything else — choosing a competition, studying, taking tests — comes later. This guide takes you from "I know nothing" to "my account is created and my profile is ready," explaining every term in plain language along the way.

We'll use a CAST contract-agent application as our worked example, because it's the easiest and most beginner-friendly way in: it's open all year round, there's no deadline, and the entry test is the most approachable EPSO offers.

First, let's decode the alphabet soup

Before you click anything, here are the only acronyms you actually need. Keep this table open in a tab.

That's it. If you understand that table, you're ahead of most first-time candidates.

Before you register: are you eligible?

Three quick checks. If you pass all three, you can register today.

1. Citizenship

You must be a citizen of at least one EU Member State. If you gain EU citizenship later, you can add it to your profile and apply from then on.

2. Languages

You need knowledge of at least two of the EU's 24 official languages. Tests in any given procedure are taken across two different languages — so you'll always use a second language somewhere in the process. (Linguistic profiles usually require three.)

3. Education and experience

This depends on the role and, for CAST, on the Function Group you target:

Your degree must be recognised by a competent authority of an EU Member State. The exact requirement is always written in the Notice of Competition or Call for Expressions of Interest — read it before you apply.

Which account do I actually create?

This is the single most confusing thing for beginners, so let's make it black-and-white. There are two systems, and which one you use depends on what you're applying to.

Both start with EU Login. Think of EU Login as the front door, and the Single Candidate Portal or EPSO Account as the room you walk into afterwards. As of 2026, CAST procedures are still handled through the EPSO Account "until further notice."

Step-by-step: creating your account (CAST example)

Set aside about 30 minutes. Have your ID card or passport next to you — the names and dates you enter must match it exactly.

Step 1 — Go to the official website

Open eu-careers.europa.eu. This is the one and only official EPSO site. Bookmark it. (Anything else asking for money to "register you" is not EPSO — registration is always free.)

Step 2 — Create your EU Login

EU Login is the European Commission's authentication service — your secure sign-in for every EU service.

1. Choose Create an account and enter your first name, last name, e-mail, and a password.
2. Make your details match your ID or passport exactly (last name, first name, date of birth). Mismatches cause problems later.
3. You'll receive an e-mail from the Authentication Service of the European Commission. Click the link to set your password. (Check your spam folder if it doesn't arrive.)
4. Set up two-factor authentication — a second verification step (for example the EU Login Mobile app). This protects your account and is required.

Step 3 — Create your EPSO Account (for CAST)

Once you're signed in with EU Login, create your EPSO Account to register in the contract-staff database.

⚠️ The golden rule: you may only ever have one EPSO Account. Having more than one can get you excluded from a selection procedure at any stage. If you think you created one years ago, recover it — don't make a new one.

Step 4 — Build your profile (your "EU CV")

Fill in your personal, educational, and professional details. This is where you enter:

• Language skills — at least two official EU languages
• Education and training — at least one qualification
• Professional experience — real, paid work relevant to the profiles you want
• A copy of an ID document, and your nationality

Good news: you fill this in once. It's saved and reused for future applications.

Step 5 — Choose your profile(s) and Function Group

Browse the contract-staff profiles (there are 20+, from Finance and HR to ICT, Law, Communication, and Translation) and pick the ones that genuinely match your background. You submit one application per profile and/or Function Group, and you can register for several if they fit.

The four Function Groups:

FG IV is the most popular target — it's graduate-level work comparable to an Administrator (AD).

Step 6 — Validate your application

Complete and validate the form in the language(s) required by the Call for Expressions of Interest. An application that isn't validated doesn't count. Once validated, your profile is live in the database.

🎉 That's it — registration done. You are now in the system.

After you register: what happens next?

Registering is the start, not the finish. Here's the CAST journey from here:

1. Reconfirm every 6 months. This is critical: if you don't update your application at least every six months, your profile becomes invisible to recruiters. Set a calendar reminder now.
2. An institution shortlists you. When an EU institution, body, or agency has a vacancy, they search the database and shortlist the profiles that fit. With CAST, the institutions come to you.
3. You take the EPSO tests. Shortlisted candidates take computer-based, multiple-choice reasoning tests: Verbal, Numerical, and Abstract Reasoning. (No EU Knowledge, no Digital Skills, no essay — that's why CAST is the gentle on-ramp.) You're usually invited about 10 days in advance. These tests are now sat online from home with remote proctoring (via the TAO/OAT or TestWe platforms): a camera and microphone stay on, you show a valid photo ID, and you follow a "clean desk" rule. Run the technical check before test day.
4. You interview with the institution. Pass the tests and the recruiting service runs its own interview/selection. This varies by institution.
5. You get a contract offer. Initial contracts typically run 6–12 months, often renewable depending on the EU body.

Remember: for CAST, registering does not guarantee a job. It puts you in the pool that institutions recruit from. For open competitions the flow is different — after registering you submit an application to a specific competition before its deadline, then sit the tests, and successful candidates go onto a reserve list that institutions hire from.

The whole journey at a glance

Before the alta (preparation):

1. Confirm you're eligible (citizenship, two languages, qualifications).
2. Decide your route — CAST contract agent (easiest start) or an open competition.
3. Gather your ID and your CV details.

The alta (this guide): 4. EU Login → EPSO Account → profile → profiles/Function Group → validate.

After the alta (the path to a job): 5. Reconfirm every 6 months → get shortlisted → pass reasoning tests → interview → contract.

Five beginner mistakes to avoid

• Creating a second EPSO Account. One only — ever. Recover the old one instead.
• Details that don't match your ID. Your EU Login name and date of birth must match your passport/ID card exactly.
• Forgetting the 6-month reconfirmation. Miss it and you vanish from recruiters' searches.
• Not checking your account. EPSO communicates through your account — get into the habit of checking it regularly (every few days during an active procedure).
• Paying a third party to "register" you. Registration on eu-careers.europa.eu is always free. There are no official paid shortcuts.

Know your rights — and where the real rulebook lives

EPSO publishes a single page of official Instructions and policies for candidates. When in doubt, that page (and the Notice of Competition or Call for Expressions of Interest for your specific procedure) always wins over any blog, forum, or coaching site — including this one. A few things worth knowing from day one:

• Need an adjustment? If you have a disability or a specific need, you can request reasonable accommodations — extra time, special equipment, adapted formats, and more. You ask for it in the application form when you apply, attaching supporting documents (e.g. a medical or disability certificate). Questions go to EPSO-ACCESSIBILITY@ec.europa.eu. Accommodations are decided case by case.
• Genuine emergency on test day? There's an official test-rescheduling policy for medical or family emergencies — so a real emergency doesn't have to end your candidacy.
• Something went wrong in a test? EPSO has a published complaint-resolution policy for testing events. You have a route to raise problems.
• It's all free, and in your language. Registering and testing cost nothing, and the portal works in all 24 official EU languages (English is the reference version if a translation lags).

Your action plan

1. Check the three eligibility boxes — citizenship, two languages, qualifications.
2. Go to eu-careers.europa.eu and create your EU Login (15 minutes).
3. Create your EPSO Account and build your profile (one account, ID-matching details).
4. Pick your CAST profiles and Function Group, then validate.
5. Set a 6-month reconfirmation reminder — and start practising Verbal, Numerical, and Abstract Reasoning.

The acronyms looked scary. The first step wasn't. Welcome to the start of your EU career.
