Quick Answer
Signal’s Android 8.28 beta lets new users create an account without providing a phone number, but the option costs a one-time $3 in the United States. Signal says the fee deters spam and payment is not linked to the account through zero-knowledge proofs. Install the current beta, save the Account ID and Account Key, and add a username if you want others to contact you.

What does Signal’s phone-numberless signup change?
Signal’s phone-numberless signup lets new Android beta users register without entering a mobile number. The feature arrives in Signal Android 8.28, which Signal developer Greyson Parrelli announced on September 16, 2026. Signal’s Android 8.28 beta announcement describes the option as an alternative registration path rather than a replacement requirement for every existing account.
The change matters because a phone number has traditionally been part of the registration process for many messaging services. Signal’s new process instead gives a numberless user an Account ID and an Account Key. Those credentials become central to the account because Signal does not provide recovery if either one is lost.
Signal’s phone-numberless signup is still a beta feature, so availability and behavior can change before a broader release. The practical response is to treat the account credentials as irreplaceable records from the moment registration is complete, rather than assuming a phone number or ordinary password-reset process will restore access later.
Why does Signal charge $3 for phone-numberless registration?
Signal charges a one-time $3 fee for phone-numberless registration in the United States because the organization says the payment is intended to deter spam. Signal also says the price can differ by country and warns that it could raise the fee if numberless accounts become a significant spam vector. The charge is therefore an anti-abuse measure, not a subscription price for ordinary use of the account.
The fee matters because removing a phone-number requirement also removes one barrier that can make automated or repeated account creation more difficult. Signal’s stated approach adds a small payment requirement to the new registration route. That does not mean payment makes an account immune from misuse, but Signal says it is designed to make large-scale abuse more costly.
Signal’s $3 numberless-registration fee also means the feature is not a free signup option, despite the privacy benefit of avoiding a phone number. Users who want to avoid the charge can continue using the standard registration route where available. Users who want the new route should confirm the displayed amount in the app because Signal says country pricing may vary.
How private is the Signal payment process?
Signal says the in-app payment for phone-numberless registration uses the same zero-knowledge proofs as its donation system, so the payment is not linked to the Signal account created through the transaction. Zero-knowledge proofs are cryptographic methods that allow a system to verify a condition without exposing the underlying information needed to prove it. Signal’s explanation means the service says it can confirm payment without tying that purchase to the resulting account.
The payment design matters because a registration fee could otherwise create a direct connection between a payment event and a messaging account. Signal says the proof system separates those records for this registration process. The claim describes Signal’s payment and account-linking design, not a guarantee that every device, app, or payment environment has no privacy considerations.
Signal’s numberless registration also does not remove the need for careful account security. A username can make an account reachable, and an Account ID and Account Key remain necessary for recovery. Users who are evaluating messaging privacy more broadly should also consider how account credentials, device access, and contact discovery affect their own situation, especially as Android passkey transfers make credential management more portable across supported password managers.
What are the Account ID and Account Key for?
Signal gives each new phone-numberless account an Account ID and Account Key, and Signal says losing either one permanently prevents account recovery. The Account ID and Account Key are not optional details that can be recreated through a standard recovery email or phone-based reset. The account setup process therefore requires more deliberate recordkeeping than users may expect from a conventional app signup.
The recovery limitation matters because a user can lose access through a phone replacement, an app removal, or an unavailable device. Signal’s stated policy means the service cannot restore a numberless account when either required credential is missing. The limitation is especially important for users who create an account specifically to avoid attaching it to a phone number.
Save the Account ID and Account Key in a secure location that remains available if the Android phone is lost or replaced. Avoid storing the only copy in the same Signal installation that could become inaccessible. Stop and review your security plan before creating an account if you cannot safely maintain a protected backup of both credentials, because Signal says the loss is permanent rather than reversible through support.
| Account item | What Signal says it does | What the user should do |
|---|---|---|
| Phone number | Phone-numberless signup does not require one for new Android beta users. | Choose the numberless route only if the $3 fee and beta limitations are acceptable. |
| Account ID | Forms part of the credentials for a new numberless account. | Store a protected copy outside the Signal app. |
| Account Key | Forms part of the credentials for a new numberless account. | Store a protected copy outside the Signal app. |
| Username | Lets other users contact the account. | Create one if receiving new contact requests is important. |
How can other people contact a numberless Signal account?
Signal numberless accounts need an optional username before other people can contact them. Signal says accounts without a username cannot be contacted by others and can only take part in chats they start themselves or groups they join through a link. The username is therefore the practical contact mechanism for a new account that does not use a phone number.
The contact limitation matters because a numberless account can otherwise appear to work normally while remaining unavailable to people who want to start a conversation. A user can still begin a chat or enter a group through an invitation link without a username, but incoming contact depends on setting one. Signal’s design gives the user a choice, but the choice changes how discoverable the account is.
Create a username during setup if friends, family members, or colleagues need a way to reach the account. Leave the username unset only if the limited contact model fits the intended use. Users should also consider whether a shared username could reveal an identity or connection they prefer to keep separate, since privacy depends on how an account is used as well as how it is registered.
Which Signal beta version includes numberless registration?
Signal Android beta v8.28.0 introduced phone-numberless registration, and Signal later issued v8.28.1 after a rollout issue left the option disabled for some testers. Signal’s official Android release page lists the 8.28.0 and 8.28.1 releases. The follow-up version matters because users who do not see the option may be running a build affected by the initial rollout problem.
Signal’s version-specific rollout shows why beta features should be checked by app version rather than assumed to appear for every tester at once. The feature is tied to the Android beta and is intended for new users registering through the numberless route. Existing users should not assume that installing a beta automatically changes how an existing account is identified or recovered.
Update Signal through the beta channel and confirm that the installed version is current if the phone-numberless option does not appear. An independent hands-on account also noted the early availability issue and the 8.28.1 fix. The rollout details reinforce that the later build is the relevant version for testers who were initially missing the setting.
What are the limits of Signal’s phone-numberless beta?
Signal’s phone-numberless signup initially requires Google Play in-app payments, so the feature does not currently work on Android devices without Google Play Services. Signal’s payment requirement is a technical limit as well as an anti-spam policy, because the registration flow depends on Google Play for the in-app transaction. Devices that do not include Play Services cannot use this initial version of the feature.
Signal’s numberless accounts also have 3 important constraints: a one-time payment is required, Account ID and Account Key loss prevents recovery, and a username is needed to receive contact from other people. Those conditions do not make the feature unsuitable, but they mean it is best for users who understand the tradeoff between reduced phone-number reliance and stricter account-management requirements.
The practical response is to decide before setup whether Google Play access, the $3 US charge, credential storage, and username-based contact fit your needs. Users who rely on a device without Play Services should wait for Signal to support another payment or registration method rather than attempting workarounds. Messaging users should also keep account-access decisions separate from broader platform changes, such as subscription bundles across messaging platforms, because billing and identity policies can differ significantly between services.
Should new users choose Signal’s numberless signup?
Signal’s numberless signup is a sensible option for new Android beta users who want to register without providing a phone number and can safely manage the resulting account credentials. Signal’s $3 US fee, Google Play requirement, and unrecoverable Account ID and Account Key are the central tradeoffs. The feature is most useful when avoiding phone-number registration is more important than using a familiar recovery path.
Signal’s username requirement also changes the decision for users who expect unsolicited contact from friends or new contacts. A username is optional, but Signal says an account without one cannot be contacted by other users. Users who plan to participate only in chats they start or groups they enter through links may find that limitation acceptable.
Install the current Android beta only after deciding where the Account ID and Account Key will be stored. Keep the credentials separate from the phone, add a username if incoming contact matters, and verify that Google Play Services are available before paying. Users who need a fully stable setup or do not want beta behavior should wait for a future broader release.
