Step 2: CBP Reviews the Application

After receiving the application, if CBP finds errors, they will reject the application. If CBP finds no errors, they will process it.

For new applications, the process can take up to 15 business days from the date of receipt. For changes to an existing ACH account, filers should allow at least three business days for processing.

Step 3: CBP Creates the ACH Account and Assigns a Payer Unit Number

Once CBP creates the ACH account, CBP will assign the filer a unique PUN, which CBP uses as a security measure. CBP will only share the PUN with the point of contact listed on the ACH Application. Payers will use the PUN to identify themselves when attempting to submit payments.
