Cisco Serial Number Lookup
Check warranty, coverage, and support status by serial number
Paste a Cisco serial below. We validate the format instantly, then confirm the exact product, its warranty and SmartNet status, and its end-of-life position with Cisco, and send you the report. Uniqcli is an authorized Cisco partner, so the coverage answer comes from Cisco records rather than from a guess.
Find your serial on the chassis label, or run show version / show inventory. Per-platform steps below.

What this Cisco serial checker returns
Being straight about this matters more than looking clever, because a serial number tool that quietly invents coverage data is worse than no tool. Cisco’s serial-to-contract database is entitlement-gated: only a partner or a customer whose Cisco.com account is linked to the contract can query it, and it is not something any website can render on the page for an anonymous visitor. So this page splits into two halves, and we are explicit about which is which.
Instant, right here
- Serial number format validation, in your browser, with no account and no login.
- Where to read the serial on a switch, router, firewall, access point, or Meraki device.
- Published End-of-Sale and Last Date of Support dates for 280 Cisco models in our EoL lookup.
- What each Cisco lifecycle milestone means for support, RMA, and software fixes.
Emailed after you ask for the report
- The exact Cisco product and orderable PID that the serial belongs to.
- Warranty status and the warranty term that shipped with that unit.
- Whether a SmartNet (SNTC) or Solution Support contract is attached, and its coverage end date.
- The current Cisco replacement, with a GPC-payable quote if you want one.
No account, no login, and no charge for the report. If your question is about contract line items, co-termination, or an entitlement transfer, the serial alone cannot answer it and we will say so, then route you to someone who can price the fix.
What the Cisco coverage report includes
Product identity
The exact Cisco model and orderable PID behind the serial, so you are quoting and patching the right thing.
Warranty context
Which warranty shipped with that unit, its term, and whether the record shows it as expired.
Support coverage
Whether SmartNet (SNTC) or Solution Support is attached to the serial, and when that coverage ends.
Lifecycle position
End-of-Sale, End of Software Maintenance, and Last Date of Support for the platform.
Replacement path
The Cisco-recommended replacement, priced from our catalog, payable by Government Purchase Card.
What we could not confirm
If Cisco returns nothing for a field, we name the gap instead of filling it in with a guess.
How to find your Cisco serial number
Every Cisco platform prints the serial in a slightly different place, and the CLI keyword changes between IOS XE, NX-OS, ASA, FXOS, and Meraki. Here is where to look on each.
Catalyst switches (9200, 9300, 9500, 3850, 2960-X)
Run show version and read the line labelled System Serial Number. On a stack, run show inventory to get the serial of every member switch, not just the active one. Physically, the serial is on a label on the rear or side of the chassis, and on some models on a pull-out tab beside the console port.
ISR, ASR, and Catalyst 8000 routers
Run show version and read Processor board ID, which is the chassis serial. Use show inventory to list the chassis plus every module, NIM, and power supply with its own serial. The printed label sits on the rear panel next to the power inlet.
Nexus data center switches (NX-OS)
Run show version to see the Processor Board ID, then show inventory for the chassis, supervisor, line card, and fabric module serials. On a chassis switch, quote the chassis serial for coverage questions, not a line card serial.
ASA and Secure Firewall
On classic ASA software, show version prints Serial Number directly. On Firepower and Secure Firewall appliances running FTD, use show version from the FTD CLI, or show inventory on 4100 and 9300 platforms to list the chassis and module serials. The label is on the rear of the appliance.
Wireless access points and controllers
On a Catalyst 9800 controller, show inventory returns the controller serial and show ap name AP-NAME config general returns the serial of a joined access point. On AireOS controllers use show ap inventory AP-NAME. On the access point itself, the serial is on the back label under the mounting bracket.
Meraki MX, MS, MR, and MV
Meraki devices have no serial CLI. Read the serial from the device label or from the Meraki dashboard under Organization then Inventory, or on the individual device page. Meraki serials look like Q2XX-XXXX-XXXX, twelve characters in three dash-separated blocks, so they will not match the Cisco hardware serial format this checker tests for.
Which serial number on a Cisco switch should you look up?
A switch label normally carries three different values and it is easy to quote the wrong one. SN is the chassis serial number and it is the one that carries warranty and contract entitlement. PID and VID are the product ID and version ID, which identify the model but not the individual unit. The MAC addressidentifies the interface, not the entitlement. Use the SN. On a stack, every member switch has its own SN and its own coverage, so check the member you are actually asking about instead of assuming the whole stack inherits the active switch’s contract.
Cisco SmartNet and device coverage checker
Warranty and coverage are two different things and they expire on different days. The warranty is what shipped with the unit, and the term varies by product line, from 90 days on some software and accessories to a year on most hardware and a limited lifetime warranty on parts of the switching range. It covers replacement of a defective unit under limited terms and nothing more. A service contract, Smart Net Total Care or Solution Support, is what buys you Cisco TAC access, advance hardware replacement at a defined response time, and the right to download maintenance software. Plenty of devices are inside warranty with no contract, and plenty of well-run networks run past warranty with contracts renewed for a decade.
Is it covered?
Whether any SmartNet or Solution Support contract is attached to that serial today.
Until when?
The coverage end date, and the service level on it, such as 8x5xNBD or 24x7x4.
What is missing?
Units in the same rack with no contract at all, which is where the risk usually hides.
If your Cisco.com account is already linked to the contract, you can check coverage yourself in Cisco’s own device coverage tooling. The reason people end up here instead is that the link is missing: the gear was inherited in an acquisition, bought through a broker, or the contract sits under a parent company account nobody has credentials for. That is exactly the case a partner lookup solves. Send the serial, or the whole inventory list, and we return it as one table.

Looking up a Meraki device?
Meraki is a genuinely different flow, so do not fight the checker above with a Meraki serial. Meraki serials are twelve characters in three dash-separated blocks, normally starting with Q, for example Q2XX-XXXX-XXXX. They will not pass the Cisco hardware serial format test above, and that is expected rather than a sign of a bad serial.
- Where to read it: the device label, or the Meraki dashboard under Organization then Inventory, or the individual device page. There is no CLI on MX, MS, MR, or MV.
- What entitlement means here: support follows the Meraki licence, not a SmartNet contract, so the date that matters is the licence expiry, whether you are on co-termination or per-device licensing.
- Warranty: hardware warranty terms vary by Meraki product line rather than being one blanket term. Send the serial and we confirm the term that applies to that model.

What the Cisco lifecycle dates mean
Once you know the model behind the serial, the next question is how much runway it has. Cisco publishes a fixed ladder of milestones in every End-of-Life bulletin, and the three that decide budget are End-of-Sale, End of Software Maintenance, and Last Date of Support.
- End-of-Life Announcement (EoL)
- The day Cisco publishes the bulletin. Nothing changes operationally yet, but the clock on every date below now starts.
- End-of-Sale (EoS)
- The last day you can order the product from Cisco. Typically about six months after the announcement. Resellers may still hold stock afterwards.
- End of Software Maintenance (EoSW)
- The last date Cisco releases bug fixes or maintenance rebuilds for the software on that platform.
- End of Vulnerability and Security Support (EoVSS)
- The last date Cisco engineering may publish a software fix for a security vulnerability. After this, a new PSIRT advisory against your platform has no patch.
- End of New Service Attachment (EoNSA)
- The last date you can attach a brand-new SmartNet or Solution Support contract to a unit that has none.
- End of Service Contract Renewal (EoSCR)
- The last date you can renew an existing support contract on the product.
- Last Date of Support (LDoS)
- The final day Cisco supports the product in any form. No TAC case, no RMA, no fix. Usually five years after End-of-Sale for hardware.
The practical read: End-of-Sale is a procurement problem, End of Software Maintenance is a security problem, and Last Date of Support is a risk-acceptance decision. A switch past LDoS with a live PSIRT advisory against its software train has no fix coming, at any support level, for any amount of money. How Cisco’s EoS and EoL policy works →

Cisco serial number lookup FAQ
How do I check a Cisco serial number?
Read the serial from the chassis label or from show version, paste it into the checker at the top of this page, and submit. The checker validates the format instantly in your browser. To get the product identity, warranty status, and support coverage behind that serial, add your name and work email and we run the lookup with Cisco and send the report back, normally within one business day.
How do I check my Cisco warranty status?
Cisco ties warranty entitlement to the serial number, not to the model, so warranty status has to be looked up per unit. If you have a Cisco.com account linked to the contract that covers the device, you can query it yourself in Cisco's own coverage tooling. If you do not, for example on inherited gear or hardware bought on the secondary market, send us the serial through the checker above and we confirm the warranty term and status with Cisco as an authorized partner.
What is a Cisco device coverage checker?
A device coverage checker answers one question: is this specific serial number currently covered by a Cisco service contract, and until when. Coverage is separate from warranty. A unit can be well inside its warranty and still have no SmartNet, or be years past warranty and fully covered. We report both, per serial, in the coverage report.
How do I check Cisco SmartNet coverage on a device?
SmartNet, now branded Smart Net Total Care, attaches to the serial number. Send us the serial and we confirm whether a SmartNet or Solution Support contract is attached, the service level on it, and the coverage end date. If you are checking a whole site, send the inventory as a list and we return it as one coverage table with the expiry dates co-terminated where that makes sense.
How do I find my Cisco device's serial number?
On IOS and IOS XE run show version and read System Serial Number, or Processor board ID on routers. On NX-OS run show version then show inventory. On ASA run show version. Meraki devices have no CLI, so read the serial from the device label or the Meraki dashboard. Every platform is broken out step by step in the section above.
Which serial number on a Cisco switch should I look up?
A Cisco switch label usually prints three different values: the serial number, marked SN, the product ID and version ID, marked PID and VID, and one or more MAC addresses. For warranty, coverage, and RMA questions you want the SN, the chassis serial. On a stack, each member switch has its own serial and its own entitlement, so look up the serial of the unit you are actually asking about rather than assuming the stack is covered as one.
What is the Cisco serial number format?
Most Cisco hardware serials are eleven characters: a three-letter manufacturing site code such as FOC, FDO, or JAE, followed by four digits for the manufacturing year and week, then four more letters and digits. FOC2412A1BC is a typical example. Meraki is the exception and uses a twelve-character Q-prefixed serial in three dash-separated blocks.
How do I look up a Meraki serial number?
Meraki serials look like Q2XX-XXXX-XXXX and are printed on the device label and shown in the Meraki dashboard under Organization then Inventory. They do not follow the eleven-character Cisco hardware format, so the format checker above will flag them. Send the Meraki serial to us instead and we confirm the model, the licence expiry date, and the hardware warranty term that applies to that product line.
Can a Cisco serial number confirm a device is genuine?
A serial lookup is a useful screen, not proof. If Cisco has no record of the serial, or the record maps to a different model than the label claims, that is a real signal worth stopping on, and it is the most common way counterfeit or relabelled gear gets caught before it ships. A serial that does return a clean record still does not certify the physical unit in front of you. If provenance matters, buy the unit through an authorized channel with the paperwork attached.
Why would a valid Cisco serial come back with no coverage?
Usually because Cisco genuinely has no active contract against that serial, but not always. Coverage can be recorded against a different party after a resale, an entitlement transfer may never have been filed, or the contract may sit under a parent company account. It does not mean the serial is fake. Where the record is ambiguous we say so and tell you what would have to be filed to resolve it.
Checking a whole inventory, not one device?
Send the serial list as a spreadsheet or a raw show inventory dump. We return one table: model, warranty, coverage status and end date, lifecycle position, and the replacement where it is warranted.
