# y-axis starts at 0, not zero - domain counts move by fractions of a percent a day. Dashed segments are estimated: reconstructed from certificate first-seen dates before daily snapshots began, not measured on the day.

? How many .co.uk domains are registered?
There are 5,776,407 active .co.uk domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
? Is .co.uk growing or shrinking?
.co.uk has grown by 31.81% over the last year (+1,393,914 domains).
? Where does the .co.uk domain count come from?
We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .co.uk domain is counted as active if it appeared in a zone file in the last 2 days, or - where no zone file is published - if a certificate was issued for it in the last 12 months.
