When does a .si domain expire and drop?
An expired .si goes straight into quarantine and is deleted about 80 days later. Here is that timeline, who runs .si, and how to register one.
An expired .si is deleted about 80 days after expiry. It enters quarantine on the expiry date: the name stops resolving but its holder can still renew it through their registrar. If it is not renewed, the registry deletes it and anyone can register it. .si is the country code of Slovenia, run by Register.si, and open to register worldwide.

Straight into quarantine, then deletion
.si has a single post-expiry stage. On the expiry date an unrenewed name enters quarantine for about 30 days: it is taken out of the zone, but the holder can still renew it and bring it back. Then it is deleted and open to registration again.
There is no separate grace or pending-delete stage, so a lapsing .si is released about a month after expiry, faster than most generics. A watched name shows the move into quarantine, which is your signal that the release is close.
Who runs .si, and since when
.si is the country code of Slovenia, delegated in 1992 and administered by Register.si, the registry service of ARNES, the Academic and Research Network of Slovenia.
Registration was once limited to Slovenian entities; today the namespace is open to anyone and governed by the registry's published general terms. The quarantine documented here comes from those terms, and our engine re-verifies it against the live record.
How to register a .si domain
A .si is open to anyone worldwide with no local-presence requirement; it is used by Slovenian businesses and by anyone wanting a short, memorable two-letter address.
Because quarantine is the only post-expiry stage, the gap between a missed renewal and a public release is short. Watch a .si you want so the quarantine does not pass unnoticed.
- Open to anyone, individual or company, with no Slovenian presence required.
- Register through an accredited registrar; the registry sells wholesale.
- Labels run from 2 to 63 characters using letters, digits and hyphens, and Slovenian characters are supported as internationalized names.
- Registration is renewable; an unrenewed name enters the quarantine below.
The .si timeline, stage by stage
The single stage an unrenewed .si passes through before deletion.
| Stage | Window | What happens |
|---|---|---|
| Renewal grace: about 45 days | Day 0 to 45 after expiry | The registration has expired but the current owner can still renew at the normal price, usually through their registrar. The name often stops resolving during this window, and nobody else can register it. Registrars frequently delete earlier than the final day, which starts the rest of the timeline early. |
| Redemption: about 30 days | Day 45 to 75 after expiry | Deletion has begun. Only the current registrant can recover the name now, typically by paying a restore fee on top of the renewal, and it cannot be registered by anyone else. A restore during this stage is a strong signal the name will not drop. |
| Pending delete: 5 days | Day 75 to 80 after expiry | The point of no return. Recovery is no longer possible for anyone, including the original owner, and the registry releases the name at the end of this fixed window. This is the stage worth acting on if you want the name. |
| Released: registrable by anyone | From about day 80 | The name leaves the registry's deletion pipeline and returns to the public pool, registrable at the standard price on a first-come basis through any registrar. Availability monitoring exists to catch this moment. |
.si technical profile
How .si publishes registration data, secures its zone, and handles internationalized names.
WHOIS and RDAP
Registration data for every .si domain is queryable over RDAP at https://rdap.register.si/ and legacy WHOIS at whois.register.si, so status, dates and record changes are machine-readable, which is exactly what our monitoring reads.
DNSSEC
The .si registry supports DNSSEC, so a domain can publish DS records and let resolvers cryptographically validate its DNS answers against tampering.
Internationalized names
The .si registry supports internationalized domain names, so labels in non-Latin scripts register as punycode alongside ordinary ASCII names.
https://rdap.register.si/
whois.register.si
The registry publishes .si status over RDAP and WHOIS and signs the zone for DNSSEC, so a name's move into quarantine is visible on the live record.
Is .si a good domain?
Where .si fits, and its trade-off.
A Slovenian address
For a business serving Slovenia, .si signals national identity and local trust, and it is the extension Slovenian customers expect.
Short and open
A two-letter suffix with no residency rule makes .si a compact choice for brands and short hacks well beyond Slovenia.
A fast drop cycle
With one quarantine and no pending-delete stage, a lapsing .si is released about a month after expiry, so there is little time to react without a watch.
Frequently Asked Questions
Common questions about .si domains.
What is .si, and who runs it?
.si is the country code of Slovenia, delegated in 1992 and run by Register.si, the registry service of ARNES. It is open to register worldwide.
How long does it take for an expired .si to drop?
About 80 days. On the expiry date the name enters quarantine, out of the zone but renewable by its holder; if it is not renewed it is deleted at the end of quarantine and anyone can register it.
Can I renew a .si that is in quarantine?
Yes, if you are its holder. Renewing through your registrar during quarantine lifts the status and reactivates the name. Once the quarantine ends without a renewal, the name is deleted.
Who can register a .si domain?
Anyone. The old requirement for a Slovenian connection no longer applies, so individuals and companies anywhere can register a .si through an accredited registrar.
What is the best way to get a .si that is expiring?
Watch it. The move into quarantine is the signal, and about 30 days later an unrenewed name is deleted and open to register, so be ready to act as the quarantine closes.
