Suspicious Daily Calls from 02 9099 7381
A contributor has flagged 02 9099 7381 (also written as 0290997381) for persistent daily calling behaviour with an unusual pattern. When the recipient answered the call, the caller mentioned the contributor's company name and then immediately hung up. This behaviour - where callers demonstrate prior knowledge of your business but disconnect when engaged - often indicates list-scraping or research activity preceding a potential scam attempt.
The calls are coming from a Symbio Networks local service number in NSW. The contributor reports receiving calls every single day from 0290997381, suggesting systematic contact attempts rather than accidental dialling.
What This Pattern Suggests
When a caller knows your company name but hangs up upon connection, several possibilities exist. The caller may be verifying that a phone number is active and belongs to a real business (often called number validation in scam operations). Alternatively, they may be gathering information before a follow-up contact attempt with a specific pitch or claim. The daily frequency from 02 9099 7381 indicates this is not a one-off misdial but rather deliberate, repeated contact.

WRITE A REVIEWFrequently Asked Questions
Why would a caller mention my company name and then hang up?
Callers sometimes verify that a phone number is genuine and connected to an active business before attempting a scam or unwanted pitch. The contributor's experience with 02 9099 7381 (0290997381) shows the caller knew the company name, which suggests they may have obtained your details from a business directory or data leak. This reconnaissance call allows them to confirm your number works before a second contact with a specific offer or false claim.
Is 0290997381 definitely a scam?
Based on the single report, 02 9099 7381 shows suspicious behaviour (daily calls, caller knowledge of company name, immediate disconnect) but cannot be definitively confirmed as a scam from one report alone. However, the persistence and pattern are concerning enough to warrant blocking and monitoring. If you receive similar calls from this number, report your experience to help build a clearer picture of 0290997381's activity.
Should I call 02 9099 7381 back?
No. Do not return calls to 0290997381. If the caller is attempting reconnaissance for a scam, calling back may confirm your number is monitored and increase unwanted contact. Additionally, calling back unknown numbers can expose you to premium-rate schemes or scams in some cases. Instead, block 02 9099 7381 and wait for legitimate contact through official channels.
Is this a Symbio Networks official number?
02 9099 7381 is allocated to Symbio Networks in NSW as a local service number, but this does not guarantee it is being used legitimately by Symbio. Phone numbers can be spoofed or used by bad actors without the telecommunications provider's knowledge. If you suspect 0290997381 is being misused, contact Symbio Networks directly via their official website or a known phone number to report the suspicious calling pattern.
What should I do if the calls from 02 9099 7381 continue after blocking?
If 0290997381 continues calling after you have blocked the number (indicating the caller may be using multiple numbers or methods), document each attempt with date and time. Report the persistent harassment to ACMA at acma.gov.au and to your telecommunications provider.
