A description of the different ways parents can verify their identity in the PV service.

3 mins to read

To improve your conversion rates, the PV service aims to make it as easy as possible for parents to verify their identity and grant permission for their child to use your app. Depending on the child’s location (which you pass to the KWS API), the PV service supports a variety of methods that the parent can use to verify their identity quickly and easily.

NOTE: You can choose which verification methods to offer parents (dependent on their child’s location) when you configure your PV service settings.

KWS supports the following verification methods:

CPF (Brazil)

Parents in Brazil can verify their identity using their CPF. The CPF (Cadastro de Pessoas Físicas or Natural Persons Register) is a number that the Brazilian revenue agency assigns to Brazilians and resident aliens who are subject to taxes in Brazil.

The parent enters their CPF number and date of birth. These details are verified by Serpro.

CURP (Mexico)

Parents in Mexico can verify their identity using their CURP. The CURP (Clave Única de Registro de Población or Unique Population Registry Code/Personal ID Code Number) is a unique identity code for citizens and residents of Mexico. Each CURP code is a unique alphanumeric 18-character string.

The parent enters their CURP, first name, and last name. These details are verified by Nubarium.

Payment card (worldwide)

Parents worldwide can verify their identity using a payment (credit or debit) card. The payment card details are verified by Stripe.

  • For parents in the U.S., a charge of $0.50 is made against the card and then refunded to the parent.
  • For parents outside the U.S., a small charge in the local currency is authorized but not actually taken from their card. Examples of the authorized amount are:
    • UK: £0.30
    • EU: €0.50
    • Canada: $1 CAD
    • Australia: $1 AUS
    • Norway: kr5.00 NOK
    • Sweden: kr5.00 SEK
    • India: ₹50.00
    • Japan: ¥50

For these charges, KWS uses the currency of the parent’s current location, which is determined by GeoIP.

ID scan (worldwide except U.S. and South Korea)

Face scan (worldwide except U.S. and South Korea) - preview

We are currently trialing face scan as a verification method for parents who do not have immediate access to their payment card or government-issued ID.

This verification method is available globally, except for the U.S. and South Korea.

KWS prompts the parent to hold their device in front of their face. Via their device’s camera, a machine-learning algorithm estimates the parent’s age.

Face scan verification is provided by Yoti.
