For individuals

A clear way to stop unwanted marketing texts.

Register your preference once. Participating businesses check their own contacts against the voluntary 0TXT register and apply matching opt-outs.

We will never sell your data. We will never send you spam.

We send only the verification code you request to join or leave. There are no ongoing tasks for you and no promotional subscription hidden inside registration.

Register my number How we protect your number

Free for individuals. Applies to participating businesses’ SMS marketing. It does not block every text or stop scammers at the network level.

1 · Verify

Use a number you control.

Enter your mobile number and the code requested through our SMS provider. Entering a number alone does not register somebody else’s phone.

2 · Record

Keep the choice clear.

Your global preference is stored as a keyed fingerprint for matching. Businesses do not receive a downloadable list of everyone registered.

3 · Match

Businesses act on their matches.

Participating businesses wash their contacts and apply suppression results before marketing. Contacts retained for continuous matching can also produce new matches as people register.

Received a 0TXT unsubscribe link?

Use the short link in that message to unsubscribe from SMS marketing by the named business. You do not need to join the shared register, create an account or enter a verification code to use that direct unsubscribe.

Know what the register can do

0TXT is a voluntary preference service. It does not control your mobile network, remove messages from your phone or compel a business that has not joined. Essential service messages are outside the SMS marketing preference.

Can I remove my number?

Yes. Verify your number to leave the register, or contact the operator about access and correction. Removal stops future global matching but does not reverse opt-outs already recorded for individual businesses or grant permission to send marketing again.
