## What to include in your fax to Barclays US

Send the written card enquiry, dispute evidence or fraud statement requested for your case. Identify the relevant transaction and case reference using the form’s 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 Barclays US

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.
