If you look at a telephone keypad with letters, 3453 can be mapped to FILE. So the number would be 555-FILE (which would be a reasonable mnemonic for something to do with taxes).
A good thought. It made me wonder if they used to advertise like that but stopped as that style of phone has all but vanished. From 2005-2010, they used 800-555-8778. In 2011, they used 800-555-4477, and then switched to 3453 in 2012.
In none of the years from 2012-2015 did they advertise on the homepage with 555-file, but I wouldn't be surprised if someone originally did pick that number for that reason and after they decided against advertising with it they stuck with the number.

What a waste of ten minutes this was.
