Yes, biometrics (fingerprints and photograph) are mandatory for most applicants. However, once you have provided biometrics for a Schengen visa, they remain valid for 59 months (nearly 5 years) in the Visa Information System (VIS). This means if you apply for another Germany or Schengen visa within this period, your existing biometrics can be reused, and you may not need to attend again unless specifically requested. First-time applicants, children aged 12 and above, and those whose biometrics have expired must provide them in person at the Visa Application Centre.
