# Country ISO Codes

This enumeration lists the supported country identifiers used across YouLend’s APIs. Each value corresponds to a **three-letter ISO 3166-1 alpha-3** that uniquely represents a country.

These codes are required when specifying the merchant’s country in API requests, such as in the `countryISOCode` field of the `ThirdPartyOnboardingModel` object.

The same set of country values is used across multiple API models and endpoints, even if the field names differ:

Used in:

* `countryISOCode` (string, enum, required) in ThirdPartyOnboardingModel → Defines the merchant’s country when creating a lead.
* `country` (string, enum, required) in `PUT /onboarding/Leads/{leadId}/organisationdetails`
  → Defines the merchant's registered country when updating company details.
