Global DSN Operator
The Global DSN operator service will no longer be available. Please consult the DSN Base Directory on these web pages or use DSN toll free dialing (94+ toll free number).
This page is provided to enable users to easily convert a DSN number to its commercial equivalent and vice versa. Note that these equivalencies are displayed in the tables. These tables are not complete and may contain errors or omissions. Contact DSN to include your organization in the directory, or to notify us of any changes.
The following tables contain Canadian DSN/Commercial equivalencies and Commercial/DSN equivalencies, respectively. Commercial equivalents for other DSN Area Codes (KYXs) are being developed and will be accessible through this page when they are completed.
