Number overview
For 050-5369-3744, multiple phone-number directories carry user reports describing SMS that announce an upcoming Norton license expiry and guide renewal (as of 2026-08-03). There are effectively no nuisance flags.
Norton's official support page lists the adjacent number 050-5369-3742 as the sender of renewal SMS for au-shop annual products, but we could not confirm any official listing of this exact number (3744). It may be another line of the same delivery platform, but this site does not identify the sender definitively.
This page previously described the number as a suspicious call fishing for personal information under a vague center name; re-verification found no support for that claim, so it was corrected.
Reported behavior
- SMS announcing that a Norton license is about to expire and guiding renewal
Sources of the reports
The descriptions on this page are based on user reports posted to third-party phone-number directories (checked as of 2026-08-03). This site has not independently verified the caller, and nothing here identifies the caller definitively. The reporting sources we checked are:
- Telnavi: registered as Norton license information (no nuisance flags)
- jpnumber: reviews describing Norton subscription-switch SMS
- Norton official support: lists only the adjacent number 050-5369-3742 as the au-related SMS sender
Care when you receive such SMS
Renew licenses via the official Norton site (jp.norton.com) or your product screen, not via SMS links. Suspect fraud for unexpected charges or messages rushing you to enter card details.
