Keep your phone number private with a rented number
Last updated
Quick answer
How can I avoid giving my real phone number online?
Give a rented number instead. With KeepANumber you rent a number for 7, 30 or 90 days, from $8.50 (US, October 2026), and read its SMS online. Shops, listings and sign-up forms only see that number, and when you stop renewing it, their texts stop reaching you.
Why does your personal number travel so far?
A phone number is one of the few identifiers people keep for decades. Once it sits in a shop's database, a delivery app or a classified ad, it is copied to partners, marketing lists and, when a company is breached, to lists that circulate for years. Unlike an email alias, most people never change their number, so every copy keeps working.
Where does a rented number help most?
- Classified ads and marketplaces: buyers text the rented number; when the item is sold, the number goes with it.
- Online shops and loyalty programmes that require a number to create an account.
- Wi-Fi portals, newsletters and contests that send a code before letting you in.
- Short-term contacts: a landlord during a search, a contractor for a job, a dating profile before you know someone.
Where should you keep your own number?
Banks, tax and health services, your mobile operator and anything tied to your legal identity. Those accounts last for years and may only accept a number registered in your name; GOV.UK One Login, for instance, cannot text a code to a number registered outside the UK. A rental ends, and the account should not end with it.
How long should a privacy number last?
As long as the people who have it might still text you. $8.50 buys a week for a quick sale; $13.50 covers a month of a listing; 90 days suits a search for a flat or a job. After the end date the number may be rented again by someone else, so do not leave it on an account you still use.
Questions about privacy numbers
Does a rented number hide who I am?
No, and we do not claim it. It keeps your own number out of other people's databases. We still keep account and payment records, and services keep their own logs.
Can people call the rented number?
No. It receives SMS only, which is often what you want for a listing: messages, not calls at night.
Can I see who texted me?
Yes, each SMS shows its sender as delivered by the network, with the time it arrived.
