Generate Transferor’s Transaction Serial Numbers

Written by Jarad on March 20, 2023

By default, FastBound generates sequential TTSN numbers according to your TTSN Format setting upon request. This ensures that you don’t accidentally use a duplicate TTSN. If you do not want to use FastBound’s automated TTSN’s, you can turn this setting off by toggling the switch to Gray.

What does TTSN stand for?

TTSN is an abbreviation for Transferor’s Transaction Serial Number.

What is a TTSN?

A TTSN is a serial number for a form 4473. This number is recorded in the box at the upper right hand corner of the first page of the form 4473. Recording this serial number in your bound book can make it much easier to trace the paperwork from your bound book to your files in storage when used properly.

How do I use the TTSN feature?

It’s simple. When creating your disposition, after you’ve chosen your disposition date and type, check the “Generate TTSN” box and click save. FastBound will automatically give you the next available TTSN.

What do I do with the TTSN FastBound generated?

You record the TTSN in the box at the upper right hand corner of the first page of a completed form 4473. Then, file the form using this number. This will save you loads of time from having to search for that exact right spot if you were to file by Name or Date. 

Is it compliant to file by TTSN?

Yes, of course. That’s why the field is on the form 4473.
