Age verification

Declare a minimum age on the order and let Kustom enforce it — a banner in the checkout, BankID verification against the customer's national identification number and a name check against the buyer.

Declare a minimum age

Section titled “Declare a minimum age”
{
  "options": {
    "verify_age": {
      "minimum_age": 18
    }
  }
}

Kustom then enforces it: a banner in the checkout states the requirement, the customer is verified through BankID against their national identification number for every payment method, and the name on the verification is checked against the buyer. A customer who doesn’t meet the age is blocked from completing the purchase.

The two older options

Section titled “The two older options”

These remain supported but are no longer the recommended approach, because they collect or verify identity without enforcing an age:

  • options.national_identification_number_mandatory requires the customer to enter their national identification number. Reading it back from the Order Management API needs a specific agreement with Kustom, and requiring it measurably costs conversion.
  • options.verify_national_identification_number additionally validates that number through a third party such as BankID.

Prefer verify_age for new integrations. It’s the only one of the three that answers the question you actually have.
