3GPP Release Coverage Matrix
Regenerated 2026-04-15. Counts include .docx, legacy .doc, and (for Rel-20)
paired .zip packages. Earlier revisions of this file counted only .docx,
which undercounted Rel-18 by ~560 specs and Rel-19 by ~75.
Totals per release

| Rel-18 | 1051 | 564 | 0 | 1615 |
| Rel-19 | 1542 | 75 | 0 | 1617 |
| Rel-20 | 42 | 6 | 48 | 96 |
Grand total: ~17,686 spec files across 13 releases (excludes .yang/.yaml
API artefacts and the backup snapshots under *.backup-20260413/).
Notes
- Rel-18 and beyond use the per-series layout (
Rel-XX/{NN}_series/). The older flatDocuments/snapshot for Rel-18 is archived atreleases/Rel-18.backup-20260413/and is not part of the current totals. - Rel-18 extends past the usual 21-38 range: 41, 42, 43, 44, 45, 46, 48,
49, 51, 52, 55 series are present (mostly legacy
.doc). - Rel-14 is the first release that includes
38_series(5G NR). - Rel-19 skips
25_series(UTRA legacy, frozen). - Rel-20 is partial and mixes
.docxwith paired.zippackages; likely still ingesting. - Series 25 (UTRA) is present through Rel-17 but not in Rel-19+, consistent with 3GPP deprecating it.
