Marketplace Phishing Scam Reports for 0421 800 902
Three contributors have reported scam activity from 0421 800 902 (also written as 0421800902), with a consistent pattern targeting online marketplace sellers. The scam involves callers or SMS senders posing as interested buyers for Gumtree listings, then pivoting to payment requests via suspicious links rather than discussing legitimate transaction details like price and postage.
The most distinctive aspect of reports about 0421800902 is the bait-and-switch tactic. Contributors describe callers initially claiming they would arrange a courier, then suddenly pressuring them to use payment apps instead of answering straightforward questions about the sale. One contributor noted the caller on 0421 800 902 avoided discussing the actual item details entirely, which is a major red flag for marketplace scams.
What Callers and SMS from 0421 800 902 Involve
Contributors report two distinct attack methods from this number. First, incoming calls where the scammer claims interest in a Gumtree listing and mentions sending a courier, but then steers the conversation toward payment app transfers. When questioned, these callers resist providing normal transaction information.
Second, SMS messages from 0421800902 arrive after initial contact, including links described as "dodgy" by contributors. The SMS approach skips price negotiation entirely and goes straight to requesting payment via the link. One contributor reported receiving an SMS from 0421 800 902 that lacked any discussion of postage or final price, which suggests the link itself is the goal, not an actual purchase.
Call and SMS Patterns
Reports about 0421 800 902 span from early February through early March, with both call and SMS channels used. Two contributors received calls on this mobile number, while one reported an SMS. One additional contributor received a missed call from 0421800902 but was uncertain about the intent. This mix of channels suggests the scammer may be working through multiple contact attempts to catch sellers off-guard.
The timing and method variation indicate a deliberate strategy targeting people actively selling items online. Contributors appear to have been selected based on active Gumtree listings, making this a targeted rather than random scam.

WRITE A REVIEWFrequently Asked Questions
Why would a buyer on Gumtree ask me to use a payment app instead of the marketplace payment system?
Payment apps like PayPal, bank transfers, or Google Pay offer no seller protection and cannot be reversed if the buyer claims they never received the item. Contributors reporting 0421 800 902 noted that legitimate marketplace buyers follow the platform's payment process. If someone insists on payment apps for a marketplace item before discussing the sale details, it's almost certainly a scam attempt. Real buyers discuss price, condition, and postage first on the platform itself, not via external links from 0421800902.
What makes the links in SMS from 0421800902 dangerous?
According to reports about 0421 800 902, the links appear designed to capture personal and financial information rather than process legitimate payments. Contributors described them as "dodgy," and one noted no actual price or postage discussion occurred before the link arrived. Clicking such links may lead to fake payment pages that steal your banking credentials, identity details, or both. The fact that the SMS skipped normal transaction negotiation entirely indicates the link is the attack vector, not a genuine checkout process.
If I've already clicked a link from 0421 800 902, what should I do?
Contact your bank immediately if you entered any financial information. Explain that you may have been phished via 0421800902, and ask them to monitor your account for unauthorised transactions. Change your passwords for any accounts where you use the same login details. If you provided identity information (name, address, driver's licence number), monitor your credit file via Equifax or Experian for signs of identity fraud. Report the incident to Scamwatch at scamwatch.gov.au and ACMA at acma.gov.au, and consider reporting identity theft to the Australian Federal Police via ReportCyber at cyber.gov.au if you believe your personal data has been compromised.
Should I trust a caller who says they can arrange a courier for my Gumtree item?
Not without verification. Contributors reporting calls from 0421 800 902 encountered scammers who mentioned couriers as a seeming legitimacy tactic, then immediately pivoted to demanding payment app transfers instead of explaining how the courier would be arranged or paid. Legitimate buyers discuss the full transaction (final price, postage cost, delivery method) through the marketplace before any payment occurs. If someone calls about your listing and avoids normal sale details, it's a red flag. Treat all items as local pickup unless you've fully negotiated postage through the official marketplace channel, not via calls from 0421800902.
How can I protect my other Gumtree listings from 0421 800 902 or similar scams?
Block 0421800902 immediately in your phone settings to prevent follow-up attempts. Use only the Gumtree messaging system to communicate with potential buyers, never phone or SMS links, and avoid sharing your personal phone number until you've finalised details and verified the buyer is legitimate. When discussing payment, always use Gumtree's built-in payment protection if available, or arrange in-person cash pickup. If a buyer insists on external payment apps or links before discussing your item's final price, they are likely running the same scam reported for 0421 800 902. Report suspicious accounts to Gumtree support immediately.
Is this the same scammer targeting multiple Gumtree sellers, or could there be different scammers using 0421800902?
The pattern across reports about 0421 800 902 strongly suggests a single scam operation or closely coordinated ring. All three reports describe the same tactic (fake buyer interest, phishing links, pressure to use payment apps) targeting sellers on the same platform. The SMS link method and call script are nearly identical across contributors. It's possible the number has been sold or shared between scammers, but the consistency indicates a single organised effort. Regardless, the consistent behaviour pattern makes it clear this mobile number should be blocked by anyone selling online.
