Nuisance Call Reports for 0423 137 901
A contributor has reported receiving at least three calls from 0423 137 901 (also written as 0423137901) over a two-week period, with no voicemail messages left on any occasion. The number is registered to an Optus mobile account, suggesting it may be a personal mobile rather than a business line.
The pattern of repeated silent or unanswered calls without follow-up messages is characteristic of nuisance calling behaviour. Whether deliberate harassment, wrong number dialling, or automated probing, repeated calls to the same number without communication indicate the caller is not attempting genuine contact.
Call Patterns for 0423 137 901
According to the contributor's report, calls from 0423137901 arrived sporadically over approximately two weeks. No specific times were noted in the report, but the frequency of three calls within a fortnight suggests persistent behaviour rather than accidental misdials.
The absence of voicemail or SMS follow-up is notable. Legitimate callers typically leave a message or explanation when reaching voicemail, especially after multiple attempts. The silence pattern reported for 0423 137 901 indicates the caller may be conducting number verification, list cleaning, or simply harassing the recipient.
What to Do If You Receive a Call from 0423 137 901
If 0423 137 901 continues to call you:
- Do: Let calls go to voicemail, block the number in your phone's settings, and monitor for further contact attempts
- Do: Keep a record of call dates and times if the pattern continues
- Do not: Answer or return the call, as this may confirm your number is active
- Do not: Engage with the caller or provide any personal information
If you answer and hear silence, hang up immediately. Do not press any keys or say anything, as this can flag your number as actively monitored and may result in more calls.

WRITE A REVIEWFrequently Asked Questions
Should I answer if 0423 137 901 calls again?
No. Let the call go to voicemail. If you answer and hear silence, hang up without speaking. Answering confirms your number is active and monitored, which may encourage more calls from 0423 137 901 or other sources that share lists of active numbers.
Why would someone call 0423137901 without leaving a message?
Repeated silent calls from 0423137901 typically indicate number verification (checking if the line is active), list cleaning for resale, or deliberate harassment. Legitimate callers leave voicemail or send SMS messages, especially after multiple attempts. The pattern reported for 0423 137 901 suggests no genuine communication intent.
Can I block 0423 137 901 on my phone?
Yes. Most Australian phones allow you to block numbers directly in Settings > Phone > Blocked Contacts or similar menu (varies by device). After blocking 0423 137 901, you won't receive further calls or messages, though the blocked calls may still be logged in your history.
Is 0423 137 901 definitely a scam?
The single report indicates nuisance calling behaviour rather than a confirmed scam. However, nuisance calls from 0423137901 are intrusive and warrant blocking. Without message content, the exact intent is unclear - it could be wrong number, list cleaning, or harassment. Report it to ACMA regardless.
What should I tell Optus about 0423 137 901?
Contact Optus (your provider) and report that 0423137901 is making repeated unsolicited calls without voicemail. Provide the dates if you have them. Optus may investigate whether the account holder is authorised, whether the phone is compromised, or whether the activity violates their terms of service.
