Intel® Boxed Processor FPO and ATPO serial numbers
Finished Process Order (FPO) and Assembly Test Process Order (ATPO) serial numbers determine if your processor is eligible for a warranty exchange or return.
All Intel Boxed Processors have the numbers inscribed on the top of the processor package.
As you enter your processor number, the socket associated with the processor appears in a drop-down list. Beneath each socket type is a list of processors. Select your processor, and a sample image appears to show you the location of your FPO and ATPO serial numbers.

Now, return to the Warranty Center to submit a claim.
|Note||Only upper-case letters are used in serial numbers. |
If the numbers aren't in the Warranty Center tool, double-check that the numbers and letters didn't get confused.
We've found that 2's are seen as Z's, and 8's are seen as B's.

How do I read the ATPO serial number for Intel Boxed Processors?
The ATPO number on the box is listed under S/N. For example, S/N: M5248TF502100 is the ATPO number. You can also use a 2D Matrix scanner to read the ATPO serial number. If you don't have the box, you can also use third-party tools and devices to read ATPO serial numbers.
Use the visible characters of the ATPO if you can't find the full serial number. Visible characters of the ATPO are the last four to five characters of the ATPO number. The markings are visible on the side of the processor. The exact number of visible ATPO characters varies from one processor to another. For example, if a full ATPO is M5248TF502100, then the visible ATPO could be 02100 or 2100.
Can I use the visible characters of the ATPO to check processor warranty coverage?
Yes, you can use the visible ATPO serial number to check processor warranty coverage and obtain processor warranty expiration dates.
How do I find Intel® Boxed Desktop Processor thermal solution markings?
The fan and manufacturer part numbers are on the labels on top of the fan. However, we use multiple manufacturers to supply boxed thermal solutions, so fan markings differ for each manufacturer. Select your fan manufacturer on the right-hand side of this page to view sample fan stickers.
- Fan Part Number (Example: E41752-002) is the first number on the fan sticker.
- Manufacturer Part Number (Example: DTC-DAA01) is usually the third line number on the fan sticker.
|Note||Both the fan part number and the manufacturer part number are required for warranty processing. |
All boxed Intel® processor thermal solutions have a three-year warranty. You can return the thermal solution without returning the processor.
