Sell Online Without Sharing Your Personal Number
List your TwinPhone number on Craigslist, Facebook Marketplace, and OfferUp. Communicate with buyers safely and ditch the number when the sale is done.
The Problem
Posting your real number on public listings exposes you to spam and scam calls.
Buyers can look up your personal information from your phone number.
Unwanted calls from old listings continue months after the item sells.
No easy way to separate buyer inquiries from personal calls.
Safety risks when meeting strangers who have your real phone number.
How TwinPhone Solves This
TwinPhone gives marketplace sellers a disposable virtual number for every listing. Post it on Craigslist, Facebook Marketplace, OfferUp, or any platform. Handle buyer calls and texts from your browser, then retire the number when the deal closes — keeping your personal number completely out of the picture.
Seller Safety
Buyers never see your real number. Protect your identity on public marketplaces where anyone can view your listing.
Dedicated Seller Line
Keep buyer calls separate from personal and work calls. Know instantly when a call is about a listing.
Disposable Numbers
Use a number for a listing, then let it go when the sale is complete. No more calls about items you sold months ago.
Browser-Based
Answer buyer calls from any device with a browser — no app download needed and no second phone to carry around.
Affordable for Sellers
Pay only for the calls and texts you make. Costs pennies per transaction — far cheaper than a second phone plan.
