(i) It has made a reasonable effort to secure such identification, and

(ii) It maintains a list containing the names, addresses, and account or credit line numbers of those persons from whom it has been unable to secure such identification, and makes the names, addresses, and account or credit line numbers of those persons available to the Secretary as directed by him.

(2) The 30-day period provided for in paragraph (a)(1) of this section shall be extended where the person opening the account or credit line has applied for a taxpayer identification or social security number on Form SS-4 or SS-5, until such time as the person maintaining the account or credit line has had a reasonable opportunity to secure such number and furnish it to the dealer in foreign exchange.
