A device distributor's supplier records have no common key with EUDAMED or the national registers. Matching them is fuzzy work I do.
- Supplier files hold names. EUDAMED keys on SRN, Belgium's FAGG on its own number, company registers on VAT, and NANDO on a four-digit notified body number.
- Names fail too. A EUDAMED search for "Mentor" returns mementor DE GmbH, and "Emergo" returns 129 certificates for makers that only share a representative.
- Each register joins the next on a different partial key, so checking one supplier is a join on a join on a join, repeated for every country.
- The supplier data is private inside the company, so an outside tool cannot see it, and an inside build rarely gets prioritised.
- If you have this problem, I'd value a quick chat.
