The German directory of undertakings that have notified the Federal Network Agency under section 5 of the Telecommunications Act. It is a statutory publication rather than a searchable register: the agency publishes it periodically as a spreadsheet giving each undertaking’s name, address and a short description of the notified activity.
Domain Rating is a dated Ahrefs snapshot of domain authority. PetroHrys Score is an independent editorial assessment of the directory’s practical business value. They are separate measurements and are never combined. Domain Rating values are dated historical Ahrefs snapshots. Domain Rating is a dated historical measurement of the shared domain, not an assessment of this individual registry page. New measurements are not collected because the Research Center does not depend on mandatory authenticated APIs. Where several registries are published on one measured domain they repeat that domain’s single dated snapshot rather than each carrying a figure of its own. Domain Rating is a third-party metric produced by their respective providers, not by PetroHrys.com. Each recorded value carries its provider and the date it was measured, and describes the domain that was measured rather than one page on it. No source has been consulted for authority score, estimated traffic and referring domains, so they are not published for any record.
Partly open The agency’s page was served anonymously with no credential and links the directory as a downloadable spreadsheet dated 5 August 2026, so login is recorded as not required. The spreadsheet was not downloaded or opened, so its contents, completeness and any limits were not observed and stay null. There is no search interface to exercise.

Assessment
Strengths
Its statutory basis is quoted by the agency itself: section 5 of the Telecommunications Act creates the notification duty, and section 5(4) requires the agency to publish this directory regularly.
The published directory carries a dated snapshot, so a reader knows exactly what point in time the list represents.
The agency states what the directory contains — names, addresses and a short description of the notified activity — so its scope is not left to inference.
Limitations
Entry follows a NOTIFICATION, not a licence. Section 5 requires an undertaking to notify intended commencement, change and termination of activity; the agency grants nothing.
It is published as a periodic spreadsheet download rather than a live searchable register, so a reader gets a dated snapshot and must re-download to see changes.
Number-independent interpersonal telecommunications services such as email and messenger services are expressly exempt from the notification duty, so absence does not establish that a service is unregulated — other duties may still apply to them.
Being recorded here proves nothing about spectrum or numbering. Notification as an operator, an individual spectrum authorisation and an allocation of numbers are three separate legal acts kept in three separate systems. German spectrum and numbering are administered separately by the same agency.
The spreadsheet was not opened during verification, so nothing about its contents, field coverage or completeness is asserted.

Best for
Obtaining the full German list of notified telecommunications undertakings as a single dataset.
Establishing the statutory notification duty that sits behind German telecoms market entry.
Not recommended for
Looking up one company quickly. There is no search interface; the directory is published as a periodic spreadsheet.
Checking an email or messaging service. Number-independent interpersonal telecommunications services are expressly exempt from the notification duty.
Preparation checklist
No checklist recorded yet.
Common mistakes
No common mistakes recorded yet.
Establishing required submission assets requires submitting a listing and observing the result. That has not been done for any directory in this dataset, so it is not published rather than estimated.

The PetroHrys Score is a first-party editorial assessment, not a third-party
authority metric. It is the weighted sum of the ten factors above, divided by ten, so the number
on this page is reproducible from the values shown. Each factor is scored from 0 to 10 by a human reviewer and weighted as shown. The definitions describe what was weighed, not a rubric: no threshold or formula maps a directory onto a value, and two reviewers could reach different numbers. The score is reproducible from the factors shown on every record, but it is an editorial judgement, not a measurement.
