A phone serial number is a manufacturer-assigned identifier for a specific device. It can help the manufacturer identify your phone when you request support. It is not the same as an IMEI, which identifies cellular equipment for mobile-network use.
What a phone serial number identifies
A serial number distinguishes one phone from other devices made by the same manufacturer. Apple says it can be used to identify a device when contacting Apple Support, while Google describes a Google device’s serial number as a unique ID. The format is manufacturer-specific; there is no single length or encoding that applies to every phone.

Serial number vs. IMEI, EID, and model number
| Identifier | What it identifies or is used for |
|---|---|
| Serial number | A specific device, especially for manufacturer identification and support. |
| IMEI | Cellular equipment; Google says a phone needs an IMEI to use a mobile network. |
| EID | The eSIM identity. Google notes that eSIM use also requires an EID. |
| Model number or model information | The phone’s model, rather than the unique identity of that individual device. |
These are separate identifiers, not interchangeable numbers. Apple lists a device’s serial number, IMEI, EID, and model information separately. If a carrier or support page asks for one specific identifier, provide that field rather than substituting another.
How to find your phone’s serial number
On an iPhone
- Open Settings > General > About.
- Find the field labeled Serial Number. You can touch and hold the number to copy it.
If you cannot access the iPhone, Apple also documents finding its serial number through Finder, Apple Devices or iTunes, the Apple Account device list, or the original packaging. Printed locations vary by model, so do not assume the serial number appears on the phone’s body.

On a Google phone or Pixel
For Google devices, check Settings > About phone or the original box. Google’s general device guidance covers serial numbers; its Pixel identifier page is specifically about IMEI and EID, so a location listed there for an IMEI is not automatically a serial-number location.
For another Android manufacturer
Menu names and identifier locations can differ by manufacturer and model. Look under the phone’s settings for an About phone or device-information page, or consult that manufacturer’s official support instructions. Check that the field is explicitly labeled Serial number.

Reading and sharing the number safely
For Apple product serial numbers, use the digits 0 and 1 rather than the letters O and I. A leading S that may appear when scanning an Apple product box’s barcode is not part of the serial number. This convention is Apple-specific; do not apply it to other manufacturers’ serials.
Treat a serial number as device information: avoid posting the full number publicly. If a warranty or support lookup requires it, enter it through the manufacturer’s official support channel.
