I have checked up those two brokers: Foreign Exchange Clearing House (FXCH) and Global Clearing Group (2pipsforex)
and I found out as I open an account with them, they are using the same banking details (I mean same bank account number) for their wire transfer.

These companies are related.

Global Clearing Group is registered in Belize and is not regulated. It clears trades through CAUFEX (Caucasus Financial Exchange), an institution supervised by the Financial Supervisory Agency (FSA) of National Bank of Georgia.
