The DORA register zip filename, part by part
The ESAs read the filename before they open the zip. Four reception checks and one DPM check depend on it, and the first sign of trouble in 2025 was files rejected within a minute for a name that looked right.

consolidation scope: IND (the entity alone) or CON (a group register)What is checked against it
| 102 | The name must match the pattern exactly: upper-case LEI, a dot, CON or IND, underscores, a hyphenated date, 17 digits, .zip. |
| 105 | The folder inside the zip must carry the same name without .zip. Several portals (CBI, CSSF, AFM, MFSA, FI, Norway) enforce this harder than the ESAs. |
| 109, 111 | The reference date must be a real date and not in the future. A file for 31 December 2026 cannot be sent on 20 December 2026. |
| 714 | entityID in parameters.csv must be rs: plus the first part of the filename: rs:635400EWECOAKJOHRI84.IND for the example above. |
| 320 | refPeriod in parameters.csv must equal the date in the filename. |
Where the pattern is different
- Ireland (CBI):
C12345_20251231_DORAREG_MiFID.zip. The C number replaces the LEI, the date loses its hyphens, and the register name is the one on the upload screen. The ESA pattern is not accepted. Details. - Belgium (NBB):
KBO_0123456789.IND_NBB_DOR_DORA_ROI_anytext.zip. The enterprise number routes the file; the LEI stays inside parameters.csv. Details. - Norway:
987999999.CON_DORA_2025-12-31_20260110123005000.zip, organisation number instead of LEI, no country or framework element. Details. - Denmark:
549300D6BJ7XOO03RR69.CON_DORA_2025-12-31_20251017105200055.zip, LEI but no country or framework element. Details. - Sweden: any name without å, ä or ö, as long as the root folder matches. Details.
- Finland:
7437007ALEZNCJGTGA67.201_RS_DORA010100_DORA_2025-12-31_20250406084300000.zip, with the reporting-level code after the dot. Details.
The packager writes the right name for each of these from a validated ESA package.
