How to Change Your Signal Phone Number
Switching your phone number on Signal might sound tricky, but it’s actually pretty straightforward if you know the right steps. As someone who’s been using Signal daily for years, I’ve changed my number a couple of times and learned a few handy tips along the way. Whether you’re upgrading your number, switching carriers, or just want to keep your chats intact, this guide will walk you through how to change your Signal phone number smoothly and without losing your data.
Why Change Your Signal Phone Number?
Before we dive into the how, let's touch on the why. You might want to change your Signal phone number because:
- You’re switching mobile providers and get assigned a new number.
- You want to keep using Signal but with a different phone number for privacy reasons.
- Your current number is compromised or you just want a fresh start.
Whatever the reason, Signal’s built-in number change feature helps keep your chats and contacts intact, which is a huge relief compared to starting fresh from scratch.
How to Change Your Signal Phone Number: Step-by-Step
Thankfully, Signal has an official "Change Number" feature that handles the heavy lifting. Here’s how I do it in my daily life — the practical, no-nonsense way.
- Back up your data (optional but recommended): Signal doesn’t store your messages in the cloud, so backup is local to your device. On Android, you can enable encrypted local backups through Settings > Chats & media > Chat backups. iPhones don’t have a backup option outside iCloud, so it’s extra important to have iCloud backups enabled if you want to preserve your chat history.
- Ensure you have access to both your old and new phone numbers: You’ll need to receive SMS or calls on both numbers during the number change process.
- Open Signal and go to Settings: Tap your profile icon in the top-left corner to access the settings menu.
- Select “Account” > “Change Number”: This will open a screen explaining what happens when you switch your number. Read through it — it’s quite reassuring.
- Enter your old and new phone numbers: Make sure you include the correct country codes!
- Choose if you want to notify your Signal contacts: Signal lets you send an automatic notification to all your contacts, or only those you have conversations with. This is super handy so you don’t have to message everyone manually.
- Tap “Next” and verify your new number: You’ll get a verification code via SMS or call on the new number. Enter it to confirm.
- Wait for Signal to finalize the number change: Your messages and groups should stick with you through the switch.
One thing I’ve noticed: the process is usually instant, but sometimes it takes a minute or two for the app to update your contacts’ view of your new number. If people still see your old number, just remind them to refresh their Signal contact list or restart the app.
Extra Tips from a Regular User
- Keep your old SIM active during the number change: If you deactivate the old number too soon, the verification step won’t work. So hold onto that SIM card until you finish the process.
- Notify non-Signal contacts manually: The automatic notification only goes to your existing Signal contacts. If you want friends or family to know about your new number but they’re not on Signal yet, send them a quick message yourself.
- Check your linked devices: If you use Signal Desktop or Tablet, they should continue working after the number change, but sometimes you may need to re-link them just in case.
- Clear app cache if things look weird: Occasionally, the app can glitch and show your old number or outdated contact info. Clearing cache or reinstalling Signal usually fixes this.
What Happens to Your Groups and Profile?
One of Signal’s coolest features is that your groups stay intact after switching numbers. You don’t have to ask your group admin to add you again or lose chat history with your friends. Your profile info (name, photo, and about) also moves over automatically.
However, if you use Signal’s registration lock PIN, you’ll need to enter it during the process to verify your identity. This is an extra security step Signal introduced to prevent hijacking your account during a number change.
Wrapping It Up: Next Steps After Changing Your Signal Number
Once your Signal phone number is switched, here’s what I recommend doing next:
- Double-check your Signal contacts: Make sure your contacts see your new number and can message you without problems.
- Update your number on other apps or services: If you've linked Signal to any external services (like for 2FA), update those with your new number.
- Keep an eye on incoming messages: Sometimes friends might accidentally message your old number if they haven’t updated their contacts yet.
- Visit signal.org for official help: The Signal support pages are always getting updated with the latest tips and fixes.
Changing your Signal phone number doesn’t have to be a headache. With Signal’s built-in features and a bit of patience, you can keep your messages, groups, and contacts all in one place. Just remember to keep that old number active during the switch and verify carefully. Trust me, it’s worth the small effort to avoid losing your chat history or missing messages.
