4What’s next

Four common methods, one pattern: the fastest route is always through your phone’s own settings, but carrier backups exist for when that fails.

Method Path / Code Source
Android (stock) Settings > About phone > Status > SIM status Android.com (official Android support)
Android (Samsung) Settings > About phone > Status > SIM card status Google Android Community
iPhone (iOS 16+) Settings > Phone > My Number Verizon (mobile carrier)
iPhone (newer layouts) Settings > Apps > Phone > My Number Consumer Cellular
USSD code (most carriers) *#62# or *#100# Reddit
Google Assistant Say “What’s my phone number?” Android.com
Carrier app (Verizon) My Verizon app Verizon
Carrier app (T-Mobile) T-Mobile app Consumer Cellular
Call a friend Number appears on recipient’s caller ID Reddit
Voicemail greeting Call voicemail from your phone Apple Support Communities

Bottom line: The settings path is the fastest method for most users. For Android users, check About phone; for iPhone users, check Phone settings. If those fail, a USSD code or carrier app will retrieve your number.

How do I find my phone number?

On Android

  • Open the Settings app.
  • Tap About phone (or About device on some models).
  • Select Status or SIM status.
  • Your phone number appears under “My phone number” or “Phone number” (Android.com (official Android support)).

On Samsung phones, the path may be slightly different: Settings > About phone > Status > SIM card status (Google Android Community).

The upshot

Android users who forget their number often don’t realize it’s two taps away. The “About phone” menu is the same place you’d check for software updates, so it’s easy to remember.

On iPhone

  • Open the Settings app.
  • Tap Phone (or Cellular on some models).
  • Your number is displayed at the top under My Number (Verizon (mobile carrier)).

On newer iOS versions, the path might be Settings > Apps > Phone > My Number (Consumer Cellular).

An alternative: open Contacts, tap All Contacts, and your own contact card (often labeled “My Card”) appears at the top (Apple Support Communities).

Using a USSD code

  • Open the Phone app.
  • Dial *#62# or *#100#.
  • Press the call button.
  • Your phone number appears on the screen (Reddit).

Note: USSD codes are not universal. The exact code depends on your carrier and country. If none works, try *#06# for the IMEI (not the phone number) or contact your carrier (Google Android Community).

Heads-up

USSD codes are not universal; the working code depends on your carrier and region. Always verify with your carrier if the code doesn’t work.

From your SIM card

  • Check the SIM card packaging or sleeve — many carriers print the number directly on it (WhatIsMyNumber.com).
  • Insert the SIM into another phone and check that phone’s settings for the active number.
  • Log in to your carrier’s website or app — the number linked to the SIM is usually displayed on the account dashboard (Verizon).

The pattern: SIM cards store the phone number, but not all phones surface it. The surest way is to use the carrier’s portal.

Bottom line: For most users, device settings are the quickest path. If that fails, a USSD code or carrier app will retrieve the number. For dual‑SIM phones, check each SIM profile separately.

How to check my phone number on iPhone and Android?

iPhone: Settings > Phone

  • Open Settings, tap Phone, look for “My Number” at the top (Verizon).
  • If you don’t see it, try Settings > Cellular > your line > My Number.

Android: Settings > About phone > SIM status

  • Open Settings, tap About phone, then Status or SIM status (Android.com).
  • On some devices, the number is directly under About phone.

Using carrier app

  • My Verizon, AT&T, T-Mobile apps all show the phone number on the account home screen (Consumer Cellular).
  • No carrier app? Try the carrier’s website from a computer.

The catch: carrier apps require login credentials, so if you’re locked out of your account, this method won’t work.

How to check my own phone number?

Using USSD codes

  • Dial *#62# or *#100# on most networks (Reddit).
  • If neither works, try *#06# for IMEI (not the number) or ask your carrier for the correct code.

From SIM card packaging

  • When you first got the SIM, the number was printed on the card or sleeve (WhatIsMyNumber.com).
  • If you still have the packaging, it’s the fastest source.

Calling a friend or another device

  • Call a friend’s phone or your own landline; the number will appear on their caller ID (Reddit).
  • Send a text message to your own email or another device; the sender’s number shows in the message.

Why this matters: calling a friend is the most low‑tech method, but it requires a working credit and a friend to answer.

How to check mobile number from SIM?

Insert SIM into another phone

  • Put the SIM into any unlocked phone and check that phone’s settings for the number (WhatIsMyNumber.com).
  • This works because the phone reads the number stored on the SIM.

Use carrier’s online account

  • Log in to your carrier’s website (e.g., Verizon, AT&T, T-Mobile) and look for “My Number” or “Line Details” (Verizon).
  • This method works even if your phone is lost or broken.

Check SIM card documentation

  • The SIM card sleeve or activation kit often has the number printed on it (WhatIsMyNumber.com).
  • If you’re a prepaid user, the number might be on the packaging.

The trade-off: SIM‑based methods are reliable but require physical access to the SIM or account credentials.

What is my phone number if I forgot?

Check phone settings

  • Android: Settings > About phone > Status > SIM status (Android.com).
  • iPhone: Settings > Phone > My Number (Verizon).

Use a USSD code

  • Dial *#62# or *#100# and press call (Reddit).
  • If the code doesn’t work, try asking your carrier’s support for the correct code.

Call a friend

  • Call a friend’s phone and ask them to read your number from their caller ID (Reddit).

Look at your voicemail greeting

The implication: if you’ve forgotten your number, start with the settings path — it’s the most reliable across all devices.

Step-by-step guide: quick methods to find your phone number

  1. Check Settings: Android: About phone > Status. iPhone: Settings > Phone.
  2. Use Google Assistant (Android): Say “What’s my phone number?” (Android.com).
  3. Dial a USSD code: *#62# or *#100#.
  4. Use carrier app: My Verizon, AT&T, T-Mobile.
  5. Call a friend and read the caller ID.
  6. Check your voicemail greeting.
  7. Look at your SIM card packaging.
  8. Log in to your carrier’s online account.

Expert perspectives

Open your phone’s Settings app, tap Device Information, your phone number will be displayed in the ‘Phone number’ field.

Android.com (official Android support)

On iPhone, go to Settings > Phone. Your number is listed at the top of the screen.

Verizon (mobile carrier support)

If you’re on a prepaid plan, the number may not appear in the settings menu. Try calling a friend or checking your voicemail instead.

Consumer Cellular (mobile carrier blog)

Some users report using USSD codes to learn their own number, but the code depends on the mobile operator and country.

Reddit (user community)

For the average user, the fastest path is through device settings. But if you’re on a prepaid plan or dealing with an older phone, the fallback methods — USSD codes, carrier apps, or calling a friend — are your lifelines. The key is knowing which method works for your specific device and carrier.
