Having recently arrived in Spain, I needed to find a specialist clinic for a minor health issue. Faced with countless clinic signs on every street, I felt a bit uneasy, unsure which ones were legitimate and reliable. I’m sure many of you have faced a similar dilemma, fearing you might end up at an unlicensed clinic that not only fails to treat your condition but also wastes your money.
After some research and effort, I’ve compiled several methods for verifying the credentials of medical companies or clinics in Spain, and I hope this helps. Most of these methods involve using official channels, which provide highly accurate information and are relatively easy to use.

Key Verification Methods
The most direct and authoritative method is to check through the official system of the Spanish Ministry of Health. Just as there are rules for [naming conventions for Spanish companies], there are strict registration requirements for healthcare. Every legitimate medical institution, from large hospitals to small clinics, must have a ‘Health Registration Number’ (Registro Sanitario).
1. National Registry of Healthcare Centers
The Spanish Ministry of Health provides a national database query platform for registered medical institutions and Spanish medical companies called REGCESS. You can find the query page by searching for ‘REGCESS’ online.
- Pros: The data is the most authoritative and has national coverage.
- Cons: The website interface may not be very user-friendly for beginners. You’ll need some basic information, such as the clinic’s full Spanish name or its registration number.
2. Websites of Regional Health Systems
In addition to the national level, each autonomous community has its own health system website, which usually offers a search function for medical facilities within its region. For example, if you are in Madrid, you can visit the website of the Community of Madrid’s Health Department. These regional searches can sometimes be more tailored to local user habits.
The table below summarizes some common verification tools and their features, so you can choose the one that best suits your needs:
| Tool | Main Function | Scope |
| REGCESS | Search for national health registration numbers and basic information | National |
| Regional Health Websites | Search for medical facilities, services, etc., within the region | Specific Region |
| Colegio de Médicos | Verify doctor’s license and registration information | National/Regional |
| Informa D&B / Axesor | Check company’s overall credit and financial status | Commercial use |
Seeking medical care is a serious matter, so spending a few extra minutes on verification is always a good idea. For more significant treatments like dentistry, cosmetic procedures, or specialist surgeries, it is extremely important to thoroughly check the credentials of the clinic and the doctor!
