What are STIR/SHAKEN standards?
STIR/SHAKEN is a set of procedures aiming to verify caller identity. They are intended to help combat unwanted calls received by members of the public.
The STIR/SHAKEN standards involve different ways to indicate whether the caller number displayed on compatible mobile devices is trustworthy. The CRTC has required all Canadian telecommunications service providers to implement these standards to combat caller identity spoofing.
Good to know
Spoofing is a technique that alters the caller ID information displayed on your phone to hide the caller’s identity. This technique is based on the principle that we are more likely to respond when we receive a call that appears legitimate (such as a local phone number). Spoofing can be used for unethical reasons such as deceptive telemarketing or fraud.
Under what conditions can a number be verified?
A caller’s number can only be verified if it meets all of the following criteria:
- The standard is applied by both caller’s and the recipient’s telephone service provider
- The voice call is made between individuals who subscribe to a Canadian telecommunications service
- The call is made via VoLTE or Wi-Fi calling
- The receiver’s device is compatible with the standards
For the time being, only VoLTE calls from Videotron subscribers can be displayed as verified on Videotron’s compatible mobile devices.
How is a verified call displayed?
A quick glance at your call display will tell you if the caller’s number has been verified. The display may vary depending on your mobile phone model:
- On Android devices, the “Verified Number” and a green checkmark indicate that the caller number has been verified
- On iPhone, the “Verified Number” is visible only in the call history
Warning: A “Verified Number” does not entirely rule out the risk of fraud. It simply means that the caller’s number belongs to them.
Which mobile devices are compatible with the STIR/SHAKEN standards?
The STIR/SHAKEN standards have been phased in since November 30, 2021. More and more devices support them, including the following mobile phones and their later models:
- iPhone SE 2020
- iPhone 11 Pro Max
- iPhone 14 Pro Max
- Samsung Note 20 Ultra 5G
- Samsung Galaxy A51/A32 5G
- Google Pixel 6
- Motorola G 5G
- LG K41S
- LG K61
- TCL 30 XE 5G
Other devices may also be compatible. We invite you to verify this information with the manufacturer.
If your device is not compatible, it will not display a “Verified Number.” If it becomes compatible as a result of an update, this note will automatically appear when a verified call is received. You do not have to take any specific action.
