Selling on Marketplaces Without Exposing Your Personal Number
Selling a bike, a phone or a sofa online usually means strangers contacting you, and many platforms ask for or display a phone number. Once it's out there, it can be scraped, added to spam lists and used in scams long after your item is sold.
What can go wrong
- Spam and scraping. Listings are a known source for spam lists.
- Verification-code scams. A "buyer" asks you to read out a code "to confirm you're real". It's actually a code to take over your messaging or marketplace account.
- Fake payment messages. Texts or emails claiming the buyer has paid and you need to "release" the money by clicking a link.
- Your number links to other accounts. A quick search can connect it to your social media and home address.
Protecting yourself
- Use the platform's built-in chat as long as possible. It keeps a record and hides your number.
- Hide your number on the listing if the platform allows it.
- Use a separate number for sign-up on marketplaces you only use occasionally, so your personal number isn't in their database at all.
- Never share a verification code with a buyer or "support agent" for any reason.
- Don't click payment links in messages. Check your account on the real site or app.
- Meet in public places for in-person handovers, and don't share your home address until you have to.
For regular sellers
If you sell often, as a hobby shop or small business, a dedicated business number that you keep long-term is the cleanest solution. You can publish it freely, you won't lose access, and your personal number stays private. A temporary verification number, by contrast, is best for one-off sign-ups. It receives the code, then you move on.
A note on temporary numbers
If you sign up to a marketplace with a rented verification number, add an email address and a strong password right away, and enable any non-SMS login protection the platform offers. That way you won't need the number again to get back into the account.
For one-off sign-ups where you'd rather not share your personal number, telly.cat rents numbers for hundreds of services and countries. You pay only when a code arrives.
