What Is a SIM Number (ICCID) and Where to Find It

A SIM number, or ICCID, is the 19 to 20 digit serial number of your SIM card. It is not your phone number. Here is where to find it on any phone.

SIM number vs phone number

Find the ICCID

• iPhone: Settings › General › About, then scroll to the SIM or eSIM section.
• Android: Settings › About phone › SIM status (names vary by brand).
• On the card: printed on the SIM or the card it came in.

When you need it

• Activating a new SIM.
• Moving your number to a replacement SIM.
• Some carrier support calls.

Keep it private

The ICCID with your personal details can help someone move your number. Share it only with your carrier. Protect your number with a number transfer PIN.

SIM PIN

A SIM PIN is a different code that locks the SIM when the phone restarts. Turning it on stops someone who takes your SIM from using it in another phone, which adds protection for your verification codes.
