How to Hide Your Phone Number on Signal
If you’re using Signal and want to keep your phone number private, you’re not alone. Many Signal users appreciate the app’s strong privacy and encrypted messaging but still wonder if it’s possible to hide their phone number while chatting. In this guide, I’ll walk you through how to hide your phone number on Signal, share some neat tricks I’ve picked up along the way, and highlight a few quirks to watch out for.
Understanding How Signal Uses Your Phone Number
First off, it’s important to understand how Signal works with phone numbers. Unlike some messaging apps where you can create an account with just an email or username, Signal **requires a phone number for registration**. That phone number acts as your identity on the platform, which helps with contact discovery and encryption key exchange.
Because your phone number is the core of your Signal identity, you can’t completely remove it from the app or replace it with a fake or email. But don’t worry — there are ways to protect your number and keep it from being exposed to people you don’t want sharing it with.
How to Hide Your Phone Number on Signal: Practical Steps
Here’s the deal: Signal doesn’t explicitly have a “hide my number” toggle because it’s designed to use phone numbers as IDs. However, there are two main strategies to keep your phone number private while still enjoying secure messaging:
1. Use Signal’s “Incognito Keyboard” and Profile Privacy Settings
While this doesn’t hide your number directly, it limits how much personal info others can see. Here’s what you can do:
- Disable “Show your phone number” in your profile. This setting controls whether your number shows up in your profile to people who have you as a contact.
- Set a Display Name and Profile Picture without your number. Since Signal shows profile info when people tap your chat, avoid putting your phone number in your display name or picture.
- Enable “Incognito Keyboard.” This stops your keyboard from learning what you type in Signal, so it doesn’t accidentally suggest your phone number when chatting.
To adjust these settings:
- Open Signal and tap your profile icon at the top left.
- Choose Edit profile, then make sure your phone number field isn’t visible or linked anywhere else.
- Go to Privacy → Incognito Keyboard and toggle it on.
This keeps your number from showing up casually, but it doesn’t stop Signal from sharing it when you message new people.
2. Register with a Secondary Phone Number
Here’s the trick that many privacy-conscious Signal users rely on: you can register Signal with a phone number that isn’t your main personal line.
This doesn't mean Signal supports usernames or emails — your account *must* be tied to a phone number. But by using a secondary or burner phone number, you shield your primary number from your contacts.
How to do it:
- Get a secondary phone number — this could be a prepaid SIM, a virtual number from services like Google Voice (where available), or a VoIP number from apps like TextNow. Just make sure it can receive SMS or calls for signal verification.
- Install Signal on your device.
- Register Signal using this secondary number.
- Verify the number by entering the code sent via SMS or call.
- Start inviting your contacts to Signal using your secondary number.
One caveat: If you use a phone number that isn’t linked to your device's SIM, you might lose some seamless integration benefits (like SMS fallback), but for pure privacy, it’s often worth it.
Bonus Tips From a Longtime Signal User
After years of chatting on Signal, here are a few less obvious tips that helped me keep my phone number private and maintain my overall Signal experience:
- Use the “Note to Self” chat for testing and backup. This is a private chat just for you, great for saving messages and confirming how your profile looks from a fresh perspective.
- Review your “Blocked” and “Disappearing Messages” settings often. These don’t hide your phone number, but they enhance privacy by limiting who can reach you and how long messages last.
- Don’t link your Signal profile to social media or other apps. That can inadvertently expose your phone number if you’re not careful.
- Be aware of Signal’s quirks: Sometimes when adding new contacts, Signal might briefly display the phone number before you exchange messages. Just a minor annoyance, but worth knowing.

Final Thoughts: Can You Truly Hide Your Phone Number on Signal?
To sum it up, Signal’s architecture is designed around phone numbers, so you can’t hide your number in the traditional sense like you might in other messaging apps. That said, by registering with a secondary number and tweaking your profile privacy settings, you can keep your personal number away from prying eyes and maintain your anonymity.
It’s a bit of a balancing act — you get robust end-to-end encryption and privacy, but you have to accept that your phone number is your Signal ID. Personally, I found using a burner number works best without sacrificing the user experience.
So, if your goal is to hide your phone number on Signal, start by deciding if a secondary number makes sense for you, then lock down your profile visibility and privacy settings. It’s definitely doable, and once set up, you’ll enjoy chatting with peace of mind.
