A dispute is unfolding between Truecaller and India’s telecom regulator TRAI over rules aimed at reducing spam calls. The disagreement centers on the 140 and 160 number series, which are officially designated for banks and telemarketers. Truecaller’s developers say users are reporting large volumes of spam calls coming from numbers in these ranges, including calls they associate with telemarketers and banks. Truecaller argues that the existing framework allowing these series for certain organizations does not prevent misuse at scale. In response to TRAI’s spam-call regulations and numbering framework, Truecaller says it is “taking on” the regulator to address what it describes as widespread spam originating from supposedly authorized numbers. The reports frame the issue as part of India’s broader efforts to curb unwanted calls, but highlight that the current approach—where certain number series are treated as authorized—may still be leaving gaps for spam callers. The conflict is presented as an escalation in an ongoing push between app-based spam reporting and regulatory controls over calling numbers and categories.
