Dooney & Bourke is the brand behind a wide range of fashion accessories, but they're mainly known for their handbags. If you've purchased one of them lately, it's important that you register the product. Doing so will ensure you have an authentic item--not a knockoff--and make you eligible for Dooney & Bourke's one-year craftsmanship guarantee.

Locate your Dooney & Bourke guarantee card. All new D&B products are accompanied with this. On the card, you'll find a satisfaction guarantee, authenticity promise, short survey, and two unique codes--the Product SKU and the Registration Number.

Open your product and locate the fabric tag inside. Authentic products will have a red, white and blue tag, with the words "Dooney & Bourke, Made in the U.S.A." on it. Flip the tag over. On the reverse side is a serial key. This is your Bag ID Number.

Submit the form. This will check the registration number within Dooney & Bourke's database, and verify its authenticity. Assuming all information that you've entered is correct and being used for the first time, you will receive a confirmation page. Your product is now registered and will be protected for one year against any craftsmanship defects that result from normal use.

Warning

If you register a fake, invalid or already-used registration number on the Dooney & Bourke website, you will receive an error notification, not a confirmation page. If you believe the error is a mistake or wish to investigate it further, use Dooney & Bourke's "Contact Us" page to contact the company directly with questions or concerns.

Buying online or from a third party? Use caution. If you do not purchase your Dooney & Bourke product directly from their website or a reputable retail outlet, you risk buying a fake. Also, be wary of sellers offering the guarantee card, because the product may already be registered. Always ask if the product is still eligible for the one-year warranty.
