How it works

This registration process acts as a search tool, allowing you to select suppliers from a database.

The registration will be validated after the supplier has submitted all the necessary information. The supplier will be notified by e-mail and assigned a user number and access key.

The supplier is wholly responsible for ensuring their EDP Distribuição registration details are up-to-date and accurate.

This system is based on a four-tier registration:
