Final Reminder - TLS Upgrade

August 17, 2022

Note, this is an implementation date change.1

Effective Tuesday, August 30, 2022, the FINRA TRACE, ADF and ORF Web API reference data downloads will no longer be accessible using the Transport Layer Security (TLS) 1.1 protocol. FINRA will disable TLS 1.1, and firms using that protocol will not be able to establish connectivity to FINRA’s secure web servers to download the files. To gain access to the FINRA API reference data downloads, firms must migrate to TLS version 1.2 by August 30, 2022.


Testing is available for this change in the testing facility (NTF). Once testing is completed, users may begin using TLS 1.2 at any time but must make this change prior to August 30, 2022.

NOTE: TRAQS users should also ensure their browsers currently support TLS version 1.2. Any TRAQS user attempting to log in whose browser only supports the TLS 1.1 protocol will be denied service.

Questions regarding this notice should be forwarded to FINRA Product Management or call (866) 899-2107.

1The original implementation date was August 29, 2022.
