Product registration cards: why every brand should use them

Updated October 31, 2026 · 5 min read

When you sell on a marketplace, the buyer is the marketplace's customer, not yours. A product registration card is the simplest legitimate way to change that.

What registration gives you

What to ask (and what not to)

Keep it short: product, where they bought it, email, and optionally order number, first name and phone. Every extra required field loses buyers. Kartzo lets you set each field to off, optional or required.

Make joining your email list a separate, unticked choice. Registering is not consent to marketing.

Warranty registration: the wording matters

In the United States, the Magnuson-Moss Warranty Act and FTC rules say a written warranty can't be made conditional on returning a registration card. You can encourage registration ("register for faster claims"), but you shouldn't say the warranty only applies if they register. Proof of purchase must still work.

"Register your warranty for fast, easy claims."

"Your warranty is only valid if you register within 30 days."

Why QR beats paper cards and URLs

Make registration worth it

Give a reason to register now: the setup video, a free bonus (the same for everyone), faster warranty service. That's what turns a 2% response rate into a list that grows every week.

General information, not legal advice. Check the warranty rules for your products and country.

Turn every insert card into a loyal customer

Kartzo gives you a QR insert card and a mobile page where buyers register their product, watch your setup video, claim the same free gift as everyone else and join your email list. Start with one product for $7 a month. 14 days free, no card needed.
