The CGS Portfolio Service allows user to send inbound and identifiers such as CUSIP, CINS, or ISIN and receive back validation flags and corresponding Issue and Issuer level descriptions and reference data. This data can be delivered and accessed via FTP, with the number of submitted identifiers counted on a quarterly basis. Quarterly submissions of CGS identifiers that exceed the predetermined number outlined in your license are subject to fees that require an additional amendment, and may indicate an insufficient license level. Submission of non-CGS identifiers are not included as part of a complimentary service.
