21+ requirement met. Restricted access can open.

Ask for the last four digits

The SSN endpoint uses a four-digit fragment—not a full Social Security number.

Check the combination

Name and date of birth give the lookup the context it needs.

Match the check to the country

U.S., UK, and Mexican checks use different information and services.

Inputs and coverage depend on the selected service.

Select a supported method for the customer’s country. Check availability before enabling a country.

Respect local input requirements

UK address checking and Mexican CURP checking use different customer information.

Confirm coverage before launch

Choose a documented method for your customer population; do not assume every country uses the same source.

If the data cannot establish age, offer another supported check according to your configuration.

Questions about SSN and international checks

Do you need the full SSN?

The documented SSN endpoint accepts the last four digits, alongside name and date of birth.

Does excluding DOB delete stored data?

No. Excluding a field controls what appears in the API response. Consult the applicable data-handling policy for retention details.

Can I use this for checkout and account signup?

Use a supported ecommerce integration for orders, or connect the API to your website’s account and access flow. Apply the returned result before granting restricted access.
