ISINs are used for a variety of purposes, such as trading and settlement. The figures maintain a standard structure, allowing institutional investors’ holdings to be tracked similarly throughout markets around the world.

The ISIN numbering system was created in 1981 and is still in use today.

But, it wasn’t extensively utilized until 1989, when the Group of 30 (G30) nations demanded that all of their participants use the numbering system to differentiate between different investment tools.

The ISIN numbering scheme must be used by anyone who trades securities worldwide. In this way, the ISIN numbering system can be thought of as the de facto standard for trading securities.

What is CUSIP?

The Committee on Uniform Securities Identification Procedures (CUSIP), which administers the whole CUSIP system, is referred to as CUSIP.

The American Bankers Association, in collaboration with Standard & Poor’s, owns the CUSIP system. The technology was set up to make the settlement procedure and the acceptance of related securities easier.

A CUSIP number is identical to a serial number in that it identifies a specific item. The base, or CUSIP-6, is made up of the first six alphanumeric characters and is used to identify the issuer.

Main Differences Between ISIN and CUSIP

  1. ISIN contains a two-character country code given by the ISO, whereas CUSIP does not.
  2. The ISIN is a nine-character code that is known for national security identification, whereas the CUSIP is made up of six characters that verify the issuer and two characters that find the issue.
