How do I find my Liing's date of manufacture and serial number?

Liing features two different dates and serial numbers - one corresponding to the carrier and one corresponding to the base. 

The Liing carrier's date of manufacture and serial number can be found on the barcode label on the underside of the carrier:

The Liing bases's date of manufacture and serial number can be found on the barcode label on the bottom of the base:

If your base only has a serial number, the date of manufacture is the same as the carrier it is linked to.
If your base has both a serial number and a date of manufacture, it is either an accessory base (extra base ordered separately), or a replacement base.

NOTE: Our seats have a lifespan of 9 years past their date of manufacture.
