We are reviewing our process for completing CTRs and had a question in regards to listing account numbers on the CTR.

When an on us customer comes in and cashes a not on us check should we be documenting our customer's account number in Part 1 Section 22 on the CTR?

We currently do not list our customer's account number in Part 1 Section 22 on the CTR due to the customer's account not being affected by this type of transaction.

We don't, your cutomer's account was not affected.

^^ This.

Said differently, think of the CTR as a "tracer" document. If you are going back to pull the original documents 3 years later what will you find when you look at the customer's account?

Nothing.

I only list our account number(s) on the doc and have never been criticized for it.

Thanks. We were just wondering because we recently went through a core conversion and our new system puts our customers account number on CTR even if it is a not on us check being cashed. So we end up having to remove their account number from CTR every time.

see if the core app has a parameter setting to fix this problem.

Likewise, we would also not list an account number in #21 if a customer bought cash in through the door to purchase a wire? Correct?

Correct. You only list the number of one of your customer's accounts if the cash transaction affects the account.

For example, if you're reporting a cash-for-cash currency exchange, no account number is reported.
