Name the TAG Immobilien department, your contact person if known, the document title and the total page count. Provide a callback number. Put personal, policy or account details only where the recipient’s form requires them.

Check the official source and recipient instructions before sending. A reviewed source confirms a published number, not live availability.

## Confirm delivery and follow up with TAG Immobilien

These are fax destinations, not voice support lines. Keep the transmission result and a copy of the documents.
