Never share a code sent to you
A buyer who asks you to forward a verification code is trying to take over one of your accounts.
Selling online
Marketplaces, classifieds and rental sites run on phone numbers — and every listing exposes yours to hundreds of strangers. Give buyers a HeyNum number, answer them from your laptop, and retire it once the sale is done.
Why a second number
With your personal number
With a HeyNum number
Set it up
It takes about a minute — and you never need to show an ID.
A local number gets more replies: pick the country of your buyers.
Buyers call and text it like any mobile, and you answer from your laptop or your phone.
Switch the number off between sales, or cancel it once everything has sold.
Practical tips
Good advice, whether or not you use HeyNum.
A buyer who asks you to forward a verification code is trying to take over one of your accounts.
Fake “payment received” pages ask for your card details. Marketplaces never pay you through a link sent by text.
Use the marketplace's own messaging for prices and terms, and your number for practical details.
Choose a busy place and check the payment has really arrived before you hand over the item.
Buyers who can't meet, overpay, or send a “courier” to collect are a classic scam pattern.
