I have two deposits on my account, I have no idea what they are, only labled as, DCD DCD ACH DEP, whats that?

I have had two deposits in the last couple months. I don't do any overseas transactions or dealings. I haven't even been overseas in 2 years. I'm clueless what this means.
Update: well the reason i mention being overseas is i know dcd is duel currency deposit
