Where can I apply for an ISIN?

In locales where a National Numbering Agency (NNA) recognized by the Association of National Numbering Agencies (ANNA) operates, this organization issues the ISIN for securities whose issuer is registered or domiciled in the country where the NNA operates.
For debt securities the NNA who issues the ISIN is either one of the international securities clearing organizations or the responsible NNA in accordance with ISO 6166.
In the case of those countries where no NNA exists, a substitute agency allocates the number.
Examples of NNAs are Euroclear and Clearstream.

Note: ANNA and NNAs have no dealings or affiliation with any third party offering commercial services for assisting to obtain or maintain ISINs. Similarly, any threats from these organizations to purge a valid ISIN from certain systems if “maintenance fees” or other monies are not paid should be viewed with skepticism. To avoid incurring unnecessary costs, we strongly recommend requesting your ISIN, CFI, and FISN only from an official NNA. The full list of official NNAs can be found here.
