I’ll probably need to update this if/when Berlin gets a new airport, but in the meantime Tegel has a few postal services for you to use.
There are several postal drops. These are identified as being in the “public area” and should be pre-security based on the map PDFs.
- Terminal A Service Center
- Terminal A, near Gate A5
- Terminal A, near Gate A13
- Terminal C, pre-security, left-hand side of the building
A stamp machine is in the Terminal A Service Center; it’s probably next to the postal drop.
