Site Identification Number (SIDN)

In an effort to drastically reduce the number of unmatched SIDNs entered due to typographical errors, the SIDN for sites will be embedded in the Pro Online application based on the software order for online users.

For desktop users, the site administrator must double key the SIDN for validation purposes.

The site administrator does not have to rekey the SIDN at the preparer level, they simply click a link that inputs the SIDN found in setup.  The tax applications pulls the SIDN to the appropriate places in the return.  The preparer does not have the opportunity to change the SIDN at the return level.
