Every mattress has a legally required law tag with the serial number. Here's exactly where to find it and why it matters.
Every mattress sold in the United States is legally required to have a law tag - a white fabric tag sewn permanently into the mattress. The tag is typically located on the side of the mattress near the foot of the bed. By law, the tag cannot be removed by anyone other than the ultimate consumer (hence the 'Do Not Remove' text, which actually only applies to the seller, not you).
The tag contains: brand name, model name, size, serial number, manufacturing date, materials list (filling and cover), and country of origin. For registration, you need the model name and serial number.
Mattress serial numbers vary in format by brand. Tempur-Pedic: 12-character alphanumeric string. Sealy/Serta: may encode the manufacturing plant and date. Casper and DTC brands: serial number is typically referenced in the order confirmation email as well as on the tag.
If the law tag has been damaged or the text is worn, contact the brand with your approximate purchase date and model name - manufacturers can often look up the serial number from purchase records, especially for DTC brands with direct customer relationships.
The law tag cannot be removed and the serial cannot be moved. Register it digitally so you have a backup when the fabric fades in year 12.

The law tag is your documentation for warranty claims - it proves the specific model and manufacturing date, which together establish the age of the mattress. It is also how the CPSC identifies recalled products. Keeping the tag intact and readable is the single most important step for long-term mattress ownership protection.
