GS1, HIBC, and the UDI-DI on the label

A UDI-DI is issued by GS1, HIBCC, ICCBBA, or IFA. A 14-digit number is often a GTIN. The public page shows that code, not a new one.

A UDI-DI is not invented by EUDAMED. An issuing entity assigns it, and the manufacturer registers that code. The entities used for EU UDI are GS1, HIBCC, ICCBBA, and IFA. The agency changes the shape of the code. It does not change the job of the code: one device model in the register.

How the shapes differ

• GS1. The device identifier is a GTIN. Fourteen digits, such as 16977660098955 or 10887714028257, are the usual public examples. The barcode on the label may also carry the production identifier (lot, serial, dates) in the same symbol. That second half is the UDI-PI. EUDAMED’s public device module is keyed by the DI, not by each lot.
• HIBCC. The HIBC supplier labelling standard uses an alphanumeric code. A DI that contains letters is a poor candidate for a “just the digits” cleanup. Stripping letters will search for a device that does not exist.
• ICCBBA. ISBT 128 identifiers, used for medical products of human origin. Rare in a general device spreadsheet, and not interchangeable with a GTIN.
• IFA. The German pharmacy product code, used as an issuing entity for some device identifiers. Again, a different shape from a GTIN.

What to paste

Paste the device identifier, not the whole barcode string and not the catalogue reference. A GTIN-14 is the right length when the issuer is GS1. A shorter GTIN is often the same number without a leading zero; the registered DI is the one EUDAMED stored, which you confirm by opening the device page. If two lookups disagree, the public record wins over the barcode parser.

The device page shows the UDI-DI that was registered. It does not reissue it, and it does not display a check-digit lecture. For the group a certificate hangs on, you still need the basic UDI-DI, which is a separate identifier even when the same agency issued both.
