You can know your Jio number using several easy methods:

• Dial USSD code: Open your phone dialer and dial *1# (for SIM 1) or *2# (for SIM 2). Your Jio number will be displayed on the screen

• Use the MyJio app: Install and open the MyJio app, log in with your Jio SIM, and your number will be shown on the home screen

• Send an SMS: Send an SMS with the text "MY NUMBER" or "MYPLAN" to 199 from your Jio number. You will receive an SMS reply with your number and plan details

• Give a missed call: Give a missed call to 1299 from your Jio number, and you will get an SMS with your number and plan information

• Call customer care: Dial 199 or 1800 889 9999 and follow the prompts or talk to a representative to retrieve your number after verification

• Call a friend or family member: When you call someone, your Jio number will appear on their phone, so you can ask them to tell it to you

• Check phone settings: On many smartphones, you can find your phone number under Settings > About Phone > SIM Status or similar

• Check SIM card packaging: If you still have the original Jio SIM card packaging, the number is usually printed on it

These methods cover both online and offline options, so you can choose whichever is most convenient for you
