Hey Google, What's My Phone Number?

Say “Hey Google, what’s my phone number?” — but on most 2026 phones the assistant (now Gemini) can’t read it aloud and instead opens Find My Device or a web search, because your number lives on your SIM, not the assistant. Fastest fix: open Settings › About phone (Android) or Settings › Phone › My Number (iPhone), or detect it automatically with the free tool below.

Detect my number

Why Google Assistant (and Gemini) can't tell you your number

Your phone number isn’t stored by Google Assistant or Gemini — it’s written to your SIM card (or eSIM profile) by your mobile carrier. The assistant can read your calendar or send a text because those live in your Google account, but your own number is a network detail it usually can’t see. Through 2026 Google is also replacing the classic Assistant with Gemini on most phones, and Gemini is even less likely to answer “what’s my number” directly — it tends to hand you a web result instead.

What actually happens when you ask

Ask “Hey Google, what’s my phone number?” and you’ll usually get one of three responses:

It opens Find My Device or your account page instead of saying the number.
It runs a web search for “what is my phone number” and shows links.
It says it can’t help — “I don’t have your phone number.”

None of these read your digits out loud, which is why people land here. The methods below always work.

Find your number on Android

Open Settings.
Tap About phone (Samsung: About phone › Status information; Pixel/stock Android: About phone › SIM status).
Read it under My phone number (or Phone number).

On a dual-SIM phone you’ll see two entries — SIM 1 and SIM 2 — so check the slot you actually use. If the field is blank, your carrier didn’t write the number to the SIM; skip to the carrier code or the detector below.

Find your number on iPhone (Siri behaves the same)

Open Settings › Phone and your number is at the top under My Number. You can also open the Phone app, tap Contacts, and look at your own card at the top. Note that Siri usually won’t read the digits aloud either — see our Hey Siri guide for the My Card setup.

Check it by carrier code instead

Most carriers let you dial a short USSD code to display your own number — useful when the Settings field is blank. A few common ones: *1# on Jio, *#100# on Vodafone UK, and #686# on T-Mobile US. Some carriers (for example AT&T and Verizon) have no reliable self-number code — use the Settings path or the carrier’s app there. Find the exact code for your network in our check your number by carrier guide.

Still shows "Unknown"? (eSIM & MVNO)

On a freshly activated eSIM, a brand-new SIM, or some budget/MVNO networks, your number often shows as blank or “Unknown” in Settings because it hasn’t been written to the profile yet. The free detector below reads your number directly off a live call, so it works even when nothing is stored on the device — something no Settings screen or voice assistant can do.

Frequently asked questions

Why won't Google Assistant tell me my phone number?

Because your number is stored on your SIM by your carrier, not in your Google account. The assistant (and Gemini) can't read it, so it opens Find My Device or a web search instead. Check Settings › About phone, or detect it automatically.

Is Google Assistant becoming Gemini?

Yes — through 2026 Google is replacing the classic Assistant with Gemini on most phones. Gemini is even less likely to read your number aloud and usually returns a web result, so use Settings or our detector to see the digits.

How do I find my number if it's blank in Settings?

A blank number usually means a new SIM or eSIM that the carrier hasn't written yet. Dial your carrier's check code (e.g. *1# on Jio, #686# on T-Mobile US) or use the free detector here, which reads it off a live call.

What's the fastest way to see my own number?

Tap Detect on this page, call the free test number, and your number appears — no app, no sign-up. It works even when your SIM stores nothing.
