title: "Allowed to register Polish (PL) companies"
canonical: https://documentation.maventa.com/changelogs/developer-changelog/2025-11-07-allowed-to-register-polish-pl-companies/
---

The changes enable support for registering Polish companies using PL:VAT identification numbers through both REST and SOAP APIs. This expands Maventa's coverage to include Poland as a supported country for company registration.

## API Changes

- Company registration endpoints now accept `PL` as a valid country
  - Param `country` in [SOAP API](https://documentation-stage.maventa.com/soap-api/#registerwithpassword)
  - Param `country` in [REST API](https://swagger.maventa.com/#/companies/postV1Companies)

## Supported Features

- Full VAT number validation using both internal format checking and external VIES verification

## Integration Requirements

When registering Polish companies, integrators must use **PL:VAT** as the business identifier (bid). The format should include the country prefix `PL` followed by the VAT registration number (e.g., `PL1132848704`).

The implementation ensures that Polish companies can be registered with the same validation standards and reliability as other supported EU countries.

> [!WARNING]
> Your application's `vendor_api_key` needs to be allowed to register Polish companies. Contact integration support at <integrations@maventa.com>.
