Can You Use Meta Muse Without a US Phone Number?

One of the most common questions about Muse is whether you need a US phone number to sign up. It's an understandable worry — many tech services are picky about phone verification. The good news: for Muse, the phone number isn't the gatekeeper. Something else is. Let's untangle it.

What signup actually requires

Muse runs on a Meta account — the same account system behind Facebook, Instagram, and Meta's other apps. When you create a Meta account, you're offered several paths: link an existing Facebook or Instagram account, or sign up with an email address or a phone number. Any of these works for Muse. There is no requirement that the number be American.

Beyond the account itself, two more requirements apply:

• You must be 18 or older. Muse is strictly adult-only.
• Age verification may ask for a card. Meta can verify age with a temporary $1 card authorization (refunded, not a charge) or a linked Instagram/Facebook account. This is about proving you're an adult, not about proving you're American.

Why your phone number isn't the real problem

Here's the part people miss: even with a perfectly valid US number, if you're physically outside the US or Canada, the signup page at muse.ai/join will show a "not available in your country or region" message. Conversely, a Canadian user registering with a Canadian number sails through, and an American expat faces the same message when traveling abroad.

The gate is location, not the phone number. So the useful question isn't "how do I get a US number?" — it's "what can I prepare now so registration is smooth when my region opens?" That preparation — a clean Meta account, age-verification readiness, a working payment method — is exactly what our Muse Account Registration Assistance service sets up for you, by the book, for personal use.

Age verification: what actually happens

Muse is 18+, and Meta takes the cutoff seriously because the agent can move money and messages. In practice, verification usually looks like one of these:

• Card authorization: Meta places a temporary $1 hold on a credit or debit card and refunds it. It's an authorization, not a charge — it typically drops off within a few business days. The card needs to support international authorizations.
• Linked social account: connecting an Instagram or Facebook account with an established history can satisfy the check, since Meta already holds age signals on those accounts.

Neither path cares where the card or number was issued — they verify you, not your country. If verification fails, it's usually a fixable mismatch: a prepaid card that blocks authorizations, an account name that doesn't match the cardholder, or a brand-new social profile with no history. Fix the underlying detail rather than retrying blindly — repeated failed attempts can trigger a temporary lock.

The traps to avoid

• Don't buy a random "US number" service expecting it to unlock Muse. The number gets you past at most one optional field; the region check remains. Paid number services also come with their own fraud and account-recovery risks.
• Don't borrow someone else's verification. An account verified under another person's identity creates recovery problems later — if Meta ever re-verifies, you can't prove you're the owner.
• Don't fake your location. Meta's terms prohibit evading region restrictions. For an agent that will hold access to your email, calendar, and payment methods, a ban mid-use is the worst possible outcome.

After you register: getting set up across devices

Once your region opens and you're registered, Muse follows you across devices with one account:

• Phone first. The iPhone (iOS 18.0+) and Android apps are the primary experience — downloads reportedly passed 5 million in under a month, per third-party estimates, so the mobile onboarding is well-worn.
• Add the web. Log in at muse.ai on your desktop — Windows and Linux users do everything here, since there's no native Windows app yet.
• Connect WhatsApp. Link WhatsApp and you can delegate tasks from chat, which is where many users end up living day to day.
• Mac users: install the desktop app. Released September 17, 2026, it can drive Mac apps like Mail, Calendar, Notes, and Messages once you grant permission.
• Pick your assistant's name. During setup you choose one of three names — Hana, Glint, or Muse — which becomes the consistent identity across every device.

Then connect the services you actually use — email, calendar, a payment method via Stripe Link — and start with one small task to learn how approvals feel before handing off anything important.

FAQ

Do I need a US phone number for Muse?
No. A Meta account can be created with an email address, and phone numbers of any country are accepted. What matters is your location: Muse currently works only in the US and Canada.

Can I register with just an email?
Yes — email is one of the supported Meta account creation methods, alongside Facebook, Instagram, or a phone number. A Facebook profile is not required.

What is the $1 charge during Muse signup?
It's a temporary authorization Meta may use for age verification — a hold, not a purchase, and it's refunded. Alternatively, a linked Instagram or Facebook account can satisfy verification.

I have a US number but live abroad. Can I use Muse?
Not until Meta expands. Availability is determined by region, so a US number alone doesn't unlock access outside the US and Canada. Prepare your registration setup and wait for the official rollout.
