## What to include in your fax to Capital One

Send the appropriate bank form with its signatures. A name change needs the evidence requested by the name-change process; tax certification uses the applicable W-9 or W-8BEN instructions.

## Check the destination and prepare your cover page

Name the processing department and the exact form or request. Include the account or case reference required by the instructions, a callback number and the page count. A cover page does not replace a signature, identity check or original document required by the form.

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 Capital One

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.
