## Short answer

CZ.NIC, z. s. p. o. accredits 48 companies for .cz, as published on 2026-09-29. It publishes no DNSSEC indication per registrar. 28 of these companies are also accredited by another country registry this site holds a list for, and 41 have a profile here because their own storefront was read. The order is the registry's own. No price, no score: this site has tested none of them.

## FAQ

### How many registrars does CZ.NIC, z. s. p. o. accredit?

48 companies, across 48 entries on the list CZ.NIC, z. s. p. o. published when it was read on 2026-09-29. Accreditation covers .cz together.

### Which of these registrars are also accredited elsewhere?

28 of the 48 companies on this list are also on at least one other registry's list this site holds, joined by the website CZ.NIC, z. s. p. o. publishes for them. The last column names the other registries for each.

### Does this page say which .cz registrar is best in Czechia?

No. The order is the registry's own, alphabetical, and no row carries a price or a score, because this site has tested none of them. Where a registrar's own storefront was read, its profile quotes the .cz price its page printed; the Czechia country page ranks those quotes by standing price, VAT included, and nothing else.
