What is a Cisco Serial Number?
A Cisco serial number is a unique alphanumeric code assigned to each device during manufacturing. It identifies the device's origin, production date, and eligibility for Cisco warranty and support.
Where to Find Your Cisco Device's Serial Number
The serial number is typically located near the manufacturer label on Cisco devices, including switches, routers, wireless access points, and phones. Examples include:
- On the back or underside of Cisco switches (e.g., Catalyst 2960, 9200, 9300)
- Near the power supply or fan trays on Cisco routers and firewalls
- Under the device on Cisco IP phones and access points

Cisco Serial Number Format Explained
Decoding your Cisco serial number reveals its manufacturing details:
| Segment | Description | Example (FCH2218xxxx) |
|---|---|---|
| First 3 Characters | Location code | FCH (China) |
| Next 2 Digits | Manufacturing year code | 22 |
| Next 2 Digits | Week of the year | 18 (May) |
| Last 4 Characters | Unique identifier | xxxx |
For example, "FCH2218xxxx" indicates manufacturing in China, in May 2018.
How to Check Cisco Serial Numbers for Warranty and Support
There are several ways to verify Cisco serial numbers, depending on whether you need to check a single device, retrieve information from the CLI, or validate a large inventory of equipment.
Method 1 – Using Cisco's Official SNCheck Tool
