AutoRoute Headers

In order to effectively manage the intra-day output process, NSCC strongly recommends participants use AutoRoute headers. The AutoRoute headers will assist participants in determining whether all cycles of a particular service have been received. The most efficient way is for participants to be set up to receive AutoRoute header records for every cycle. The headers provide cycle numbers, record counts, date and time stamps and many other fields as described on page two of this notice or on NSCC’s formats.nscc.com web-site. Please contact your relationship manager regarding your AutoRoute set up.

If you have additional questions, please call your Relationship Manager or e-mail the undersigned at Pinguanta@dtcc.com.
