Intelligence Cloud - Insights reason code mappings

Telesign Intelligence responses may provide extra explanation of how we calculated the risk recommendation for your number, in the form of insights reason codes. Codes that provide an overall conclusion on the relative transaction risk level associated with your phone number are found in the “category” package. Codes in the other packages provide insights on the factors contributing to that overall conclusion. If Insights reason code mappings are used for your account, you may use the tables below to look up the meaning of each code.

category

Reason codes that provide an overall conclusion on the relative risk presented by the transaction, by placing the transaction in a risk category. This is determined based on weighting the risk and trust signals indicated by the other reason codes.

CodeNameMeaning
10010low activityNot enough activity or attributes to classify the transaction as either risky or trustworthy.
10020low regular activityTrustworthy category, based on past behavior.
10021regular activityMost trustworthy category, based on past behavior.
10030low-risk irregular activityRisky category, based on past behavior.
10031medium-risk irregular activityHigh-risk category, based on past behavior.
10032high-risk irregular activityHighest-risk category, based on past behavior.
10040irregular number typeThis number has risky static attributes (like VOIP phone type or being on a blocklist).

a2p

Reason codes specific to application-to-person messaging (a2p). These are automated messages sent to a human, like verification codes, appointment reminders, etc. These reason codes are organized into multiple sub-categories.

activity

Reason codes related to how much activity was observed for this number, compared to what would be expected for a good user. This takes into account the number of communications transactions (calls, SMS, etc.) to or from this number, the quantity of unique numbers communicated with, and the number of accounts communicated with.

20002high long-term activityMore than expected activity for this number over the past 90 days.
20003high short-term activityMore than expected activity for this number over the last 24 hours.

20010no activityVery low volume of verification traffic, or none at all, was ever observed on this number.
20011low long-term activityLow volume of verification traffic on this phone number over the past 90 days.
20012low short-term activityLow volume of verification traffic on this phone number over the past 24 hours. Very low volume of verification traffic, or none at all over the past 90 days.
20014continuous successful long-term activityContinuous successful regular volume of verification traffic on this number over the past 90 days.
20015high unsuccessful long-term activitySignificant volume of unsuccessfully verified traffic from this number over the past 90 days

range

Reason codes related to how active a risky range (series of consecutive numbers) that the number belongs to has been, if applicable, compared to a good phone number.

📘

Understanding range

Phone number
13105551
13105552
13105553
13105554

In the example above, let’s say the number you submitted to the service is 13105552. Even if there has been no risky activity for that particular number, there might still be risky activity for most other phone numbers in the 131055xx range. In this case the risky activity of the range would contribute to the overall risk level we determine for the submitted number.

CodeNameMeaningRisk signalTrust signal
20101no range activityVery little activity, or none at all, for a risky range that this number belongs to over the past 90 days. Also returned if the number does not belong to a risky range.
20105high short-term range activityVery significant activity for a risky range that this number belongs to over the last 24 hours.
20106high long-term range activityVery significant activity for a risky range that this number belongs to over the past 90 days.
20107very high long-term range activityExtremely significant activity for a risky range that this number belongs to over the past 90 days.
20108very high short-term range activityExtremely significant activity for a risky range that this number belongs to over the last 24 hours.
20109continuous successful long-term range activityContinuous successful regular volume of verification traffic from a range this number belongs to over the past 90 days
20110high unsuccessful long-term range activitySignificant volume of unsuccessfully verified traffic from a range this number belongs to over the past 90 days

other

Other A2P reason codes that do not fall into the sub-categories above.

CodeNameMeaningRisk signalTrust signal
21003machine-like activityBehavior pattern that suggests this number is being used by a bot. Although we expect a submitted number engaged in A2P traffic to communicate with automated systems, we don’t expect the user of that number to be an automated system.
21016machine-like range activityExtremely high volume of verification traffic in a very short period (less than 1 hour) on the range this number belongs to.
