use Drupal\Core\Entity\EntityTypeInterface;
// if you make a field belongs to a node just change $entity_type to 'node'
function hook_entity_bundle_field_info_alter(&$fields, EntityTypeInterface $entity_type, $bundle) {
  // D8 => $entity_type->id()
  // D9 => $entity->getEntityTypeId()
  if ($entity_type->id() === 'user') {
    if (isset($fields['field_user_id'])) {
      $fields['field_user_id']->addConstraint('UniqueField', ['message' => t('this id is used before with another user')]);
    }
  }
}
