## What to include in your fax to Interactive Brokers

Use the signed account-closure request or futures-transfer form. Transfers require the delivering broker, account details and positions.

## Check the destination and prepare your cover page

Identify the receiving department, document type, sender, callback number and page count. Put account or patient identifiers only where the receiving 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 Interactive Brokers

These are fax destinations, not voice support lines. Keep the transmission result and a copy of the documents. Confirm with the receiving department that the packet is complete and can be processed; a delivery receipt does not establish acceptance or a decision. Check with that department before sending a duplicate.
