What Callers from 02 8645 3404 Do
Silent calls dominate the reports for this number. Two separate contributors picked up to find either complete silence or what was described as "creepy breathing" with no verbal response.

WRITE A REVIEWFrequently Asked Questions
Why does 02 8645 3404 stay silent when I answer?
Two contributors reported silent calls or breathing sounds with no verbal response from 0286453404, which is a tactic used to confirm active numbers for follow-up scam attempts or to evade identification. Legitimate callers identify themselves; silence indicates evasion.
Is 02 8645 3404 actually from Commonwealth Bank?
No. One contributor was told 0286453404 was Commonwealth Bank, but Commonwealth Bank does not call customers requesting personal details unprompted. This is a confirmed impersonation tactic. Always hang up, then call your bank directly using the number on your card to verify.
Why am I receiving multiple calls from 02 8645 3404 and similar numbers like 02 8645 3429?
A contributor reported receiving calls from a cluster of sequential Blacktown numbers (02 8645 3404, 02 8645 3405, 02 8645 3429), which indicates systematic auto-dialling or coordinated calling campaigns rather than individual contact attempts. Block all variants and report the pattern to ACMA.
What should I do if 02 8645 3404 calls claiming to be my bank?
Hang up immediately. Do not provide any information. Contact your bank directly using the phone number on the back of your card or their official website to verify if they initiated contact. 0286453404 has been reported for exactly this impersonation tactic.
How do I block 02 8645 3404 and related numbers?
Most smartphones allow you to block individual numbers directly in your call settings. For 0286453404 and variants (02 8645 3405, 02 8645 3429), block each separately. Contact your provider (Optus) to request blocking the number range, or ask about call filtering services that silence suspected spam numbers.
Should I report 02 8645 3404 to authorities?
Yes. Silent calls and bank impersonation are violations of Australian telecommunications laws. Report 0286453404 to ACMA (acma.gov.au) for silent calling breaches and to Scamwatch (scamwatch.gov.au) for the Commonwealth Bank impersonation claim. Provide the dates and times from your call logs.
