The financial code won't always be 3CR - it varies based on which broker-dealer your account is with (Pershing is just the "clearing firm". Sometimes the first three characters of your account number will be the same as your office code, but not always as some broker-dealers have more than one set of characters for their accounts, but will still have just one "office code". If you're unsure of your office code, you will have to ask your broker. @NeilWinward
