Get a Signal verification code on a temporary number

Signal asks for a phone number on the very first screen, before any chat, any contact, any setting. Type your signal number into that field with the country flag matched to it, tap continue, and Signal texts a six-digit code for verification. A phone number for signal here lets you receive that SMS online without handing over a personal number: get an active one above, enter it exactly as shown, and watch this page for the message rather than a push notification on your phone.

Every Signal number is shared online, so more than one person can receive a code from this service around the same time. That is normal for a single registration, needed once and never again, and it is why numbers for signal stay free here. If someone else's code shows up first, wait a moment and refresh — a fresh SMS usually lands once the queue clears.

A US and a Canadian option both carry the +1 country code, so the registration screen treats either the same way and never asks a follow-up question about the country itself. Pick the country that matches the account you want, or use whichever one is marked active if the country does not matter to you.

Signal rate-limits how many codes any one Signal number can request in a short stretch, and once that limit is hit the registration screen swaps the usual continue button for "Verify you're not a robot." That puzzle is not personal — Signal is guarding against scripted sign-ups online, and a shared number that several people used recently crosses that threshold faster than one nobody has asked for a code on yet. Solve the puzzle honestly, tap continue again, and you receive the SMS as before. If the puzzle keeps reappearing on the same one, get another active one instead of retrying it.

When Signal switches to a phone call

If the SMS attempt times out, Signal offers "Call me instead" and reads the code aloud over a voice call. This service only surfaces incoming SMS on this page, not a live call, so do not wait on that option — get another active number and stay on the text-message path so the code arrives here.

What a Registration Lock PIN blocks

Signal lets an owner set a Registration Lock PIN, and once that is on, a fresh code alone will not move the account onto a new device — Signal also demands that PIN. If a number here was used for Signal before and its previous owner set a PIN, re-registering on it stalls no matter how many codes you request. There is no way to guess a PIN you never set. Get a different active number rather than fighting a PIN-locked one; Signal will say plainly that the account needs its PIN to continue. A fresh number rarely hits either the puzzle or a leftover PIN, and a private number from SV Number gives you exactly that — one for signal verification that is yours alone for the session, about $1 for 20 minutes, refunded automatically if the code never arrives. Signal covers the puzzle, the call fallback, and PIN recovery at signal.org, worth reading if a specific number keeps getting stuck.

A Signal number here is receive-only online. You cannot send a message from it before registration finishes, and you cannot reply to the code SMS from this page — Signal only needs that one code, and a shared number hands over exactly that and nothing more. Once entered, Signal keeps messaging on your device from there; this page keeps showing whatever SMS lands, but the chat history never lives here.

A shared one will not stay private afterward, either. Anyone who opens it later can read the next SMS sent to it — another code, a re-verification attempt, a security prompt — the same way you just did. Never leave an account registered on a Signal number you plan to walk away from.

None of that makes a shared number the wrong tool for this job — catching a single code at no cost every time. Where it runs out of room is a puzzle that keeps reappearing or a PIN left behind by a stranger, and that is the gap a private number closes.
