Gelbes Heft (U-Heft): What It Is, Why No One Can Force You to Show It, and What to Do If It's Lost

The Official Rule

The Gelbes Heft, more formally the Kinderuntersuchungsheft, is Germany’s standard child health record. It documents every U1 through U9 developmental checkup, and as of January 1, 2026, it also documents dental early-detection exams (Z1 through Z6), following a change that folded dental checkups formally into the same booklet. Newborns from mid-February 2026 onward receive a version of the Heft that already includes this dental section built in from the start. You’ll typically be handed the booklet at the birth clinic, or by your hebamme or Entbindungspfleger if you had a home birth, and the general guidance is to hold onto it until your child turns 18.

The detail that surprises a lot of parents, newcomers especially, is who is and isn’t allowed to ask to see it. No institution, not a Kita, not a school, not the Jugendamt, is legally permitted to demand access to the full booklet. What they can require is the Teilnahmekarte, a detachable card built into the Heft specifically for this purpose, which documents that your child attended their scheduled U-checkups and has age-appropriate vaccination coverage, without exposing the detailed medical content of the rest of the record. If a facility pushes for more than the Teilnahmekarte, that request goes beyond what they’re entitled to ask for.

If the booklet is lost, the underlying information isn’t gone with it. Every result documented in the U-Heft was also entered into the practice’s own patient file at the time of the checkup, so your Kinderarzt, or the birth clinic or hebamme if the loss happens very early, can issue a replacement booklet and re-enter the previous results from their own stored records.

There’s also a digital option: an electronic version, the eU-Heft, has been offered through statutory (and many private) Krankenkassen since 2022, alongside the paper booklet rather than replacing it. Longer term, the plan is to fold the U-Heft fully into the electronic patient record (elektronische Patientenakte, ePA) as a structured digital document, though that broader digitization is a medium-term project rather than something already in place everywhere. Separately from the U-Heft itself, statutory Krankenkassen now create a general ePA for every insured member on an opt-out basis, children included, so it’s worth knowing that until your child turns 15, you decide as their legal guardian whether they have one at all.

If your child was born outside Germany, you don’t need to arrange anything special in advance to get a U-Heft started. Your Kinderarzt opens one at your next scheduled appointment. Bring whatever documentation you have of past checkups and vaccinations from your home country, since this information can generally be transferred into the German record rather than your child starting with a blank history. If your federal state runs a formal reminder system for U-checkups, it’s also worth getting documented proof of any exams already completed abroad, so your local notification office has an accurate record and doesn’t flag a checkup as missing when it already happened elsewhere.

What Real People Say

The most common real-world question isn’t about the booklet’s contents, it’s the panic that follows misplacing it, and that panic is largely unnecessary once you know how the replacement process works. Parents describe assuming a lost U-Heft meant reconstructing their child’s medical history from memory, and being relieved to learn their Kinderarzt already had everything on file and could simply issue a fresh copy with the previous results carried over.

The Teilnahmekarte rule is the other point that trips people up, mostly because it’s easy to assume a Kita or school registration process requires handing over the whole booklet the way other official paperwork does. Parents who’ve asked directly describe facilities generally sticking to the Teilnahmekarte once it’s pointed out that this is what the rule actually requires, rather than pushing for the complete record.

Step by Step

1. Keep the U-Heft somewhere you’ll actually remember, and treat it as a document you hold onto through your child’s entire childhood, not something tied to a single appointment.
2. When a Kita, school, or other institution asks for proof of checkups, offer the Teilnahmekarte specifically, not the full booklet, that’s what the rule actually requires.
3. If it’s lost, contact your Kinderarzt first (or the birth clinic or hebamme if the loss happened very early), rather than assuming the medical history itself is gone.
4. Ask your Krankenkasse about the eU-Heft if you’d like a digital backup alongside the paper version, it’s been available since 2022.
5. If your child was born outside Germany, bring whatever foreign checkup and vaccination documentation you have to your first Kinderarzt appointment in Germany, so it can be transferred into the new U-Heft rather than starting fresh.
6. Check whether your federal state runs a U-checkup reminder system, and if so, submit proof of any exams already done abroad to keep your record accurate.

Compliance Note

This page explains the general framework for the U-Heft and how it’s typically handled in Germany, but it is not medical advice. Specific practice fees, regional reminder systems, and the pace of the ePA digitization rollout can all vary and change over time. For anything specific to your child’s records, confirm directly with your Kinderarzt or your Krankenkasse.
