The voucher is not personalized and it may be passed on or given away, but not resold.
The voucher for the annual pass must be exchanged for an original annual pass within 3 years of purchase at the Zoo cash register (main entrance no. 5+6). No admission with only voucher! The original annual pass is valid for 12 months from the date of exchange. The digital photo for the annual pass is taken at the Zoo cash register on site. Therefore the presence of the future holder is mandatory. For family annual passes, please all family members, as everyone will receive a single annual pass.
