Japan Securities Dealers Association Implements “Number Request (Incoming Call Restriction)” Feature

Tokyo, Japan – September 11, 2025 – The Japan Securities Dealers Association (JSDA) is pleased to announce the implementation of a new security feature, “Number Request” (also known as incoming call restriction), on its main telephone lines. This initiative, effective from September 11, 2025, aims to enhance the security and reliability of communications with the Association.

The introduction of the Number Request feature signifies the JSDA’s commitment to safeguarding its operations and ensuring that interactions with its stakeholders are conducted through legitimate and verified channels. This system is designed to prevent unsolicited and potentially disruptive calls from unregistered or withheld numbers.

What is “Number Request” (Incoming Call Restriction)?

The Number Request system is a security measure that allows an organization to control incoming calls by allowing only registered or explicitly permitted phone numbers to connect. When this feature is activated, calls originating from numbers that have not been added to an approved list will be automatically rejected or redirected to a holding message.

Purpose and Benefits of the New Feature:

The primary objectives behind the JSDA’s adoption of this feature are multifaceted:

  • Enhanced Security: By restricting calls from unknown or withheld numbers, the JSDA significantly reduces the risk of fraudulent activities, spam calls, and potential disruptions to its essential services. This helps to create a more secure communication environment.
  • Improved Efficiency: Limiting the volume of unsolicited calls allows the JSDA’s staff to focus their attention on legitimate inquiries and important communications, leading to improved operational efficiency and responsiveness.
  • Protection of Stakeholders: This measure indirectly protects the Association’s members, partners, and the general public by ensuring that any communication purporting to be from the JSDA originates from a secure and verified source, thereby preventing individuals from being misled by impersonators.
  • Streamlined Communication: While initially a restriction, the system ultimately aims to create a more predictable and manageable communication flow for all parties involved.

How This May Affect Incoming Calls:

For individuals and organizations who regularly contact the Japan Securities Dealers Association, it is important to be aware of this new policy. Calls originating from a private number (where the caller ID is withheld) or from a number that is not recognized by the Association’s system may encounter the Number Request feature.

The JSDA encourages all its stakeholders to ensure that their contact information is up-to-date and to consider registering their primary contact numbers if they anticipate frequent communication with the Association. Further details on how to register numbers or inquire about the Number Request system are expected to be made available on the JSDA’s official website.

Looking Ahead:

The Japan Securities Dealers Association is continuously seeking ways to improve its services and strengthen its operational integrity. The implementation of the Number Request feature is a proactive step towards a more secure and efficient future for communication within the securities industry. The Association appreciates the understanding and cooperation of all parties as it adopts this important security enhancement.
