Letter of Intent

The Letter of Intent (LOI) is a written application to participate in the AES.

• If you plan to file via another method other than ACE AESDirect, complete the Letter of Intent Form (LOI) to apply for AES filer certification.

Parameter Change Request

For filers that frequently receive AES Verify messages, you may submit a Parameter Change Request to EID.parameterchange@census.gov. In order to submit your request, your company must use the Parameter Change Request Form.

The Parameter Change Request requires the following information:

• at least five Internal Transaction Numbers (ITNs) of shipments
  • filed within the same month
  • with the same Schedule B/HTS Number
  • that generated the same verify message

Once your request is received, the Economic Indicators Division's Micro-Analysis Branch will investigate your request, make a ruling, and respond directly to the submitting party. If you have any questions, please email EID.parameterchange@census.gov
