Just emailed CHASE GW, was I supposed to list my SSN?

[Mistakes]

Oops, I listed the account number minus the last 4 which are showing as XXXX on my credit report but should I have listed my SSN?  YIKES!

It isn't recommended to e-mail your SSN (ever) because of Identity Theft, someone could hack your e-mail acct., etc. You should've called first and find out what your entire acct. number was. IMO.
