Open Signal
Go to the registration screen right after installing Signal.
Enter the +377 number
Select Monaco (+377) in Signal's country picker, then paste the digits your dashboard shows after +377 into Signal.

Signal sends a 6-digit code by SMS or voice call. SMS codes appear in your PhoneBorn dashboard next to the +377 number; type the code into Signal to finish.
Tips for Monaco numbers
- After +377, Monaco mobile numbers begin with 6 — a quick check that you pasted the whole number.
- Only need one code and the country doesn't matter? Ukraine costs $0.18 for Signal, against $0.25 here.
- Set “Who can find me by number” to Nobody and use a Signal username instead.
Why use a Monaco number for Signal?
Day-to-day life in Monaco runs on WhatsApp, Instagram and Facebook, yet Signal remains the app for private conversations without exposing your personal number. A +377 number keeps that account tied to the country without using your personal SIM.
Residents commuting from France: Most of Monaco’s workforce lives in nearby French towns, and a separate Monaco line keeps work in the Principality apart from a French personal number.
Signal identities are tied to the number; losing it means losing the registration.
