Apps do not have access to operator data. Their names come from users, directories and guesswork.
Three sources
- The network — passes the number and the operator, never the subscriber's name.
- Crowdsourced databases — labels users added themselves: "courier", "bank", "spam".
- Public directories — landline numbers of organisations.
Why a wrong name appears
Numbers are reused: a company closes, the range is reassigned, and the old label stays. The older the database, the more noise it contains.
Why "spam" is not a verdict
The label comes from a person who may be mistaken or motivated. If a call is expected, verify the organisation through its website.
What a directory can tell you
Objective facts: the operator, the range, the region of issue and the line type. No legal service shows the subscriber's name — only the operator has that data.
