Medical Certificate in Poland and Doctor's Note in Poland: What's the Difference?
Poland's formal, statutory sick-pay certificate is called a zwolnienie lekarskie (a medical leave certificate). It is generally issued electronically, in the ZUS ZLA format, by a doctor or dentist authorised by ZUS to issue it (most often your own treating doctor) directly to ZUS (Zakład Ubezpieczeń Społecznych, Poland's social insurance institution) and to your employer. This formal document is generally tied to an examination within the Polish healthcare system; it isn't something an online-only service can issue on ZUS's behalf. Our online general medical certificate is a separate, complementary document intended for purposes such as insurance, visa applications, legal matters, education, sport, and travel, rather than a replacement for the formal ZUS-linked zwolnienie for statutory sick pay. If your only need is documenting illness to your employer for statutory Polish sick pay, the usual route is generally your treating doctor issuing a zwolnienie lekarskie through the ZUS ZLA system. Freelancers and B2B contractors operating outside a standard employment contract may face different documentation expectations than employees covered by ZUS, so it's worth checking directly with your client, insurer, or the relevant institution about what they will actually accept before relying on either type of certificate. In everyday English this is often just called a doctor's note for Poland, even where the official local term differs.

| Local document name | Zwolnienie lekarskie, commonly issued in the electronic ZUS ZLA format. The informal, colloquial term used in everyday conversation is "L4." |
|---|---|

| Who typically issues it | A doctor or dentist authorised by ZUS to issue e-ZLA certificates, most often your own treating doctor, after examining you directly |
| How it's typically submitted | Generally transmitted electronically by the issuing doctor directly to ZUS and to your employer, without you needing to hand over a paper form yourself |

Note on our certificates: GetMedicalCertificate does not issue the formal ZUS-linked zwolnienie lekarskie and cannot transmit anything directly into the ZUS ZLA system. Our general medical certificate is intended for other purposes, such as insurance, visa, legal, education, sport, and travel documentation, where a doctor's review and a signed PDF are what's requested, rather than statutory sick pay through ZUS. If your only need is documenting illness to your employer for statutory Polish sick pay, the formal route is generally through your own treating doctor's zwolnienie lekarskie, and it's worth speaking to your employer or HR contact first about which document they actually expect to see.
In practice, most people researching medical certificates in Poland are already broadly familiar with how the ZUS system works through their employer, HR department, or accountant, and are looking for something different: a same-day document for a specific external request. That might be an insurer asking for medical evidence to support a claim, a university requesting paperwork for mitigating circumstances, a sports club requiring fitness clearance before a competition, or an airline asking for fit-to-fly confirmation before a flight. Those are the situations our online certificates are generally built for, and they typically sit alongside, rather than inside, the formal ZUS sick-pay process.
Requirements for what counts as acceptable medical documentation can vary by employer, institution, and individual situation, and Poland's sick-pay and social insurance rules are subject to periodic change. The detail above reflects general public information about ZUS and RODO rather than a specific legal reading, and Poland's administrative detail here is less firmly documented in our research than some other markets we cover. Treat it as general orientation, not exact legal advice, and check directly with ZUS, your employer, or a Polish legal or HR adviser if a specific case turns on the exact rule. Last reviewed July 2026. Always confirm current rules before relying on them for a specific case.
All Certificate Types Available in Poland
Every certificate type is reviewed by a doctor registered to assess cases in Poland. Choose the one that matches your situation. Our certificates are a complementary option alongside Poland's formal ZUS-linked zwolnienie lekarskie, not a replacement for it. Each request goes through the same core process: an online assessment, a genuine doctor review, and a same-day PDF if the doctor considers it clinically appropriate to issue one.
Sick Leave Certificate
For documenting illness to an employer, school, or institution for purposes outside Poland's formal ZUS sick-pay system, for example freelance/B2B arrangements, a second supporting document for an employer, or short-term absence notes. Not a substitute for the formal ZUS-linked zwolnienie lekarskie required for statutory sick pay.

Private consultation costs are typical ranges reported for private doctor visits in Poland and vary by location, clinic, and specialism. Public-system appointments may cost less where available, but generally involve longer waiting times and are not always geared toward same-day, purpose-specific documentation.
How GetMedicalCertificate Compares to an In-Person Doctor Visit in Poland
We don't track a named local online alternative in Poland, so here's a straightforward comparison against the most common alternative: booking and attending a private in-person doctor visit.
A typical private consultation in Poland costs roughly 150-350 zł and generally requires booking an appointment, travelling to a clinic, and waiting for an available slot, which can take anywhere from same-day to several days depending on the city and specialism. Our certificates start from 169 zł, are completed entirely online, and are generally delivered the same day, usually within 30 minutes of doctor approval. Every certificate includes a verification reference so the issuing details can be checked independently, which isn't something every in-person paper note provides. As with any medical assessment, a doctor reviews every case individually before deciding whether to issue a certificate. If it isn't clinically appropriate to do so, you receive a full refund rather than a certificate. For many of the purposes we cover, such as insurance, visa, education, sport, and travel documentation, the main practical difference against an in-person visit is time and logistics rather than the underlying clinical standard: you still get a genuine assessment, just without needing to take time off, travel to a clinic, or sit in a waiting room.
This comparison covers our general certificate types against a typical private consultation. It does not apply to Poland's formal, ZUS-linked zwolnienie lekarskie for statutory sick pay, which is generally issued by a ZUS-authorised treating doctor directly into the ZUS ZLA system. This is a process our online certificates are not designed to replace.
Our Poland Medical Team
Every Poland certificate is reviewed by a doctor registered to assess cases in Poland. A clinician will only issue a certificate after assessing your case and if it is clinically appropriate to do so. If not, you receive a full refund. Our doctors review your case for the purpose you've requested, such as insurance, visa, legal, education, sport, fitness, or travel documentation. They do not issue Poland's formal ZUS-linked zwolnienie lekarskie, which is generally handled by your own treating doctor within the Polish healthcare system.
Registered practitioners, not a call centre.
Every doctor is independently verified against their national medical council before they see a single patient - including across Poland.

Generally, no. Poland's formal, statutory sick-pay certificate is normally issued electronically by your own treating doctor directly into the ZUS ZLA system, tied to ZUS (Zakład Ubezpieczeń Społecznych) and your employer. Our online certificate serves other purposes, such as insurance, visa applications, legal matters, education, sport, and travel documentation, rather than statutory sick pay through ZUS. If you specifically need statutory sick pay in Poland, your usual route is generally to contact your own treating doctor about a zwolnienie lekarskie rather than requesting one of our certificate types.
A zwolnienie lekarskie is Poland's medical leave certificate, generally used to document illness for statutory sick-pay purposes. It's typically transmitted electronically to ZUS, in the ZUS ZLA format, by the doctor who examines you, and is also generally shared with your employer, without you needing to submit a paper form yourself. Colloquially, Polish speakers often just call it an "L4," though that's an informal term rather than the official name of the document.
Yes. You can request a general medical certificate online, reviewed by a doctor after a genuine assessment of your case, for purposes outside the formal ZUS system, such as insurance, visa, legal, education, sport, or travel documentation. The doctor asks you relevant questions about your situation before deciding whether to issue the certificate, in the same way an in-person consultation would, just without the need to travel to a clinic.
Many sports clubs in Poland request medical clearance for competitive participants, sometimes referred to as a zaświadczenie lekarskie o zdolności do uprawiania sportu (a certificate of fitness to practise sport). Requirements vary by club, league, and sport, so it's worth checking with your specific club what format they expect. Our sports fitness certificate is designed to cover this kind of request and is valid for 12 months.
Our general medical and sick leave documentation certificates cost 169 zł, which includes the doctor's review, your PDF certificate with certificate verification, and same-day email delivery. This compares to typically 150-350 zł for a private in-person consultation in Poland.
Yes. We handle personal data in line with RODO, the Polish name for the EU GDPR. Your medical information is only seen by the doctor assessing your case and is not shared with third parties, and you retain the usual RODO rights over how your data is stored and used.
Same day in almost all cases, usually within 30 minutes of doctor approval, provided your assessment is complete and no further information is needed. If the doctor needs to ask a follow-up question, delivery may take a little longer while you respond, but it's still generally completed the same day.
Yes. In everyday English, "medical certificate" and "doctor's note" describe the same kind of document, and we use both terms for Poland. Whichever term the person or institution asking for one uses, our certificate is reviewed by a doctor and designed to meet that request.
