A real phone number for Signal

Signal is chosen by people who care about privacy, and a separate number takes that one step further. With a ZuteSIP number you can register Signal without linking it to your main mobile contract, and keep receiving codes for as long as you hold it.

A privacy-minded number for a privacy-minded app

Signal needs a phone number to register, but it now lets you set a username and control who can see or find you by your number. Those settings reduce exposure inside the app. Using a dedicated number for registration keeps your primary SIM out of the picture entirely.

Journalists, researchers, consultants and people who simply prefer compartmentalised communication often keep Signal on its own number for this reason.

SMS, voice calls and the registration lock

Signal verifies a number with a code sent by SMS, with a voice call available if the text does not come through. Both reach ZuteSIP: the text in your live dashboard, the call in a SIP app, the browser dialer or a forwarded phone.

Signal also offers a registration lock tied to your Signal PIN. When enabled, anyone trying to register your number on a new device needs the PIN as well as the code. It is one of the most useful protections you can switch on.

Registering Signal on your ZuteSIP number

  1. Create your ZuteSIP account with an email address and buy a mobile or local number.
  2. Install Signal on your phone and enter the number with its country code.
  3. Open the dashboard to read the SMS code, or tap the call option and answer it.
  4. Create a strong Signal PIN and enable registration lock in account settings.
  5. Set your number visibility and discoverability to match how private you want to be.

Troubleshooting a missing Signal code

Why long-term ownership matters on Signal

Signal stores very little on its servers, so your number and PIN are central to getting back in after changing phones. If the number expires, re-registering becomes difficult, and registration lock only protects you while you remember the PIN.

ZuteSIP numbers can be kept as long as you want, with renewals taken automatically from your wallet. Signal on desktop links to your phone, so the phone registration is the one to protect.

Choosing a number type

A mobile number is the most straightforward choice for Signal. A local geographic number can also be used with the voice call option, though Signal decides which numbers it accepts. Toll-free numbers are better reserved for business lines. Any type starts at the same price.
