What is a trace number?

A trace number is a 15-digit number used to track inbound and outbound ACH transfers. It is issued by the sending institution, and can be provided to your receiving institution to track the impending transfer even before it has arrived in their system.

You can obtain your Brex trace number by reaching out to Brex Support, which can then be provided to the party that’s receiving your ACH for tracking purposes. Please be sure to wait 1 full business day after initiating the ACH, however, so the trace number has time to be generated and assigned.

For inbound ACHs, you can also ask your beneficiary for their trace number, and provide it to us for tracking purposes. This can be especially helpful if you notice your transfer is outside of standard processing time.
