Open your phone Settings, head to About or Status, and scroll until you see ICCID. If you cannot reach Settings, dial *#06# or read the long 19- or 20-digit code printed on the SIM card. Those few actions cover almost every consumer scenario and work on both iPhone and Android devices.
Understanding why you might need your ICCID
Mobile carriers use the ICCID to recognise the exact SIM you are using, which allows secure activation, troubleshooting, and number porting. Device fleet managers also bulk-query ICCIDs to pair thousands of sensors with the right data plans. Whenever support asks for “the SIM number,” they almost always mean the ICCID not the IMEI or IMSI.
Finding your ICCID on your smartphone: step-by-step instructions
For iPhone users
- Open Settings › General › About.
- Scroll down and locate ICCID beneath IMEI and EID.
- Long-press the field to copy it for live chat or email support.
For Android users
Because Android skins vary, follow the closest match:
- Settings › About phone › Status › SIM status, then read ICCID.
- If the field is hidden, tap the SIM Slot you want and look for ICCID.
- Alternatively, open the dialler, enter *#06#, and your ICCID appears alongside IMEI.
Troubleshooting tips
If you still do not see the number, update the operating system, re-insert the SIM tray, or reboot the phone. Some dual-SIM models display ICCIDs only when a SIM sits in the selected slot, so briefly swap trays if necessary.
Locating the ICCID on your physical SIM card or packaging
Every plastic SIM has its ICCID laser-etched alongside the gold contacts, usually below a barcode. The digits always start with the industry identifier 89 and end with a checksum. Older cards print small black text; newer eSIM activation cards embed the number beneath a QR code. If the print has worn away, check the original SIM packaging because carriers duplicate the ICCID on the cardboard holder.
Retrieving ICCID for IoT devices: advanced methods
Using AT commands for popular modules
Industrial modems expose the ICCID through the command AT+CCID (SIMCom, u-blox, Telit) or AT#CCID (Sierra). Send the command over UART, USB, or TCP, and the modem echoes back the full ICCID, typically within one second.
Leveraging connectivity management platforms or APIs
Large fleets often use a Connectivity Management Platform. Portals from Twilio Super SIM, Telnyx, or Emnify let you query ICCIDs by IMEI or device label and export bulk CSVs. REST APIs do the same programmatically, making it easy to patch a missing ICCID into your asset database.
Alternative methods to obtain your ICCID
- Contact your carrier through live chat or IVR and provide account verification; they can read the ICCID attached to your line.
- Use USSD codes, although availability differs by region; some operators return the ICCID when you dial a self-care short code after inserting the SIM.
- Device dashboards supplied by many modern routers show SIM identifiers alongside signal strength and data usage.
Important considerations when accessing your ICCID
Treat the ICCID like any other sensitive identifier because social-engineering attacks can abuse it to request SIM swaps. Never post screenshots with the full number visible on social media. When explaining issues to support, specify whether you are sharing ICCID, IMEI, or IMSI, because the acronyms look similar but represent very different things.
FAQs
1. Can I find my ICCID without my phone?
Yes, read the code printed on the SIM card or on the original packaging, which both contain the full ICCID.
2. Is my ICCID printed on my eSIM?
Most eSIM activation cards and QR sheets display the ICCID beneath the QR code, even though no physical chip exists.
3. What if my carrier restricts ICCID access?
Some prepaid carriers hide ICCIDs in software, so you must read the tiny digits on the SIM itself or contact support directly.
4. Why is my ICCID different from what I expected?
Carriers sometimes replace SIMs during network upgrades, so the ICCID changes while the phone number remains the same; confirm the latest card is installed.
