Is it safe to send my health card to a school or a gym?
Yes, if you limit the data and mark the copy. Your name and CIP are enough to identify you in healthcare; your Social Security number is almost never needed and is very sensitive. Send the copy with the unneeded data covered and the recipient marked on the image.
Why they ask for it
Schools and summer camps ask for it so they can get your child medical care; gyms and insurers, to prove coverage. It almost always ends up sent by email or through the WhatsApp group of the day.
That copy sits in school offices, shared folders and personal phones for years, with nobody remembering to delete it.
The real risk
The health card concentrates data that shouldn't travel together: the CIP is unique and lifelong (RD 183/2004), and the Social Security number — which some regions print on the card — is used for employment and benefits. Leaked, it opens the door to employment and administrative fraud.

What to show and what to hide on your health card
The health card carries a CIP-SNS that is unique for life; the Social Security number and the DNI number are optional fields depending on the region (RD 183/2004). To identify yourself as a patient or member, this is enough:
Show
- Full name
- CIP
- Region or issuing entity
Hide
- Social Security number (very sensitive: employment and benefits)
- DNI number if it appears
- Barcode if they don't require it
Legal basis and sources
- RD 183/2004, which regulates the individual health card
Frequently asked questions
- Which health card details should I cover?
- The Social Security number — the most sensitive item: it's used for employment and benefits — plus the DNI number if your region prints it and the barcode if they don't require it. Your name, the CIP and the issuing entity are enough to identify you.
- Can I store my health card in Ofuska?
- Yes. It's stored encrypted like any other document, with front and back, and you can redact it with the brush and rectangles and mark it with the recipient mosaic before sending it.
