Questions and answers
Checking a company in Luxembourg
Is Luxembourg's RCS automatically connected?
No. Until stable, licence-compatible production access is confirmed, only VIES and global checks are reported as automatic.
Which identifier should I use in Luxembourg?
The RCS number is the most precise; compare the result with the VAT ID, name, office, invoice and payment recipient.
Coverage limitation
The RCS can be searched through Luxembourg Business Registers, but we have not confirmed unrestricted production API access for automated individual queries. The national check is not reported as performed.
