.ar Domain: Argentina's Official Country Extension
.ar is Argentina's country code extension, entered in the root zone on 23 September 1987, which makes it one of the oldest extensions in Latin America. The zone is run by the state itself: the sponsoring organisation recorded at IANA is the Secretaría Legal y Técnica of the Presidency, and the unit that actually operates the zone is the national domain registry directorate within that same secretariat, known publicly as NIC Argentina. Registration, renewal and transfer all run through the government's Trámites a Distancia platform, with no accredited registrar layer in between.
Registering from outside Argentina is open, and you do not need to incorporate a company there. Article 4 of the regulation splits users by residency: residents hold a CUIT/CUIL/CDI tax number plus a Level 2 fiscal key from the tax authority, while non-residents receive an identification number issued by NIC Argentina itself. No Argentine address, local contact person or trustee service appears anywhere in the rules. What non-residents do owe is identity verification: a certified copy of a passport, a notarised signed declaration, and an apostille from the country of origin.
Registering directly under .ar is far newer than the extension itself; this zone reached general availability on 15 September 2020. If you are after a short address this is the right place, but go in knowing one limit: names shorter than four characters are closed under .ar directly. If your brand is three letters, look for the same name in com.ar, which does allow three characters. Check whether your candidate is free on the domain name search page.

.ar Domain Lifecycle
What happens day by day after it expires
Day 0 is the domain's expiry dateIn short: for .ar the post-expiry timeline is set by the registry, so it differs from one extension to the next. The diagram below shows the windows that actually apply to .ar, day by day. One thing never changes, whichever extension you hold: renewing before the expiry date is always the cheapest and safest route.
Domain Is Available (Available)
A .ar address at this stage has not been taken yet, and it goes to whoever registers first. Check the name you have in mind — if it is free, it can be yours within minutes.
Domain Is Active (Active Period)
Once registration is complete, the domain is registered to you for the term you selected. You can renew at any point before it expires to keep it active, or switch on auto-renewal so you never have to watch the date.
Redemption Period (Redemption Period)
The domain is not released the moment it expires — during this window it is still yours and can be recovered. Some extensions charge an extra restore fee at this stage, so renewing before expiry is always the cheaper route.
Domain Is Available Again
Once deletion completes, the domain leaves the system and anyone can register it — popular names are often taken the same minute by someone watching. Keep auto-renewal on so a name you care about never gets this far.

Frequently Asked Questions About .ar Domains
The questions people actually ask before registering — answered plainly.
-
Yes. Article 4 of the regulation divides users into residents and non-residents of Argentina and grants both the right to register. Non-residents are not required to obtain an Argentine tax number; NIC Argentina issues them an identification number of its own. The registry even publishes the numbering: it begins with 40 or 41 for individuals and 50 or 51 for legal entities. No Argentine address, branch, local contact or trustee service is required anywhere in the rules.
-
The zone itself asks for none; the document requirement comes from your residency status. If you are not resident in Argentina, user verification requires a certified copy of your passport or ID, a notarised signed declaration and a legalisation or apostille from your country of origin. Legal entities add a power of attorney and notarial certification of legal representation. Resident applicants submit no paper at all; electronic verification by the tax authority is enough.
-
One year is the only option. Article 20 of the regulation states that a registration is valid for one year and offers no multi-year term, so you renew annually. Renewal opens 30 days before expiry. Your name does not go dark the moment it expires: the same article grants a 30-day grace period during which delegation stays active, so your site and mail keep working. A second period of 15 days follows.
-
Because that limit is specific to this zone. NIC Argentina opened names of 1, 2 and 3 characters in second-level zones such as com.ar, net.ar, org.ar and tur.ar, but its announcement expressly held the first-level .ar zone outside that scope. Directly under .ar the floor is four characters. Try your three-letter name in com.ar; the ceiling is 50 characters at both levels.
-
Yes, within a defined set. Article 12 of the regulation permits the letters of the Spanish and Portuguese alphabets including ñ and ç, accented vowels and vowels with a diaeresis, digits and the hyphen. So á, é, í, ó, ú and ü are all usable. A name may not begin or end with a hyphen, and it may not begin with xn--, which means you submit the Unicode form rather than punycode.
-
Article 24 of the regulation treats a transfer as the name passing to another NIC Argentina user, and adds a consequence worth planning around: the transfer counts as a new registration, so the term restarts. Like registration itself, the process runs on the Trámites a Distancia platform, and non-resident users may carry out transfers too. You can start the steps from the domain transfer page.
-
The registry publishes its own WHOIS service at whois.nic.ar and also offers an RDAP service. The response arrives with a legal notice citing Argentina's Personal Data Protection Act 25326 and Decree 1558/01, which means personal data is shown within the limits those instruments set. You can check the status of a name from the whois search page.
-
No. Argentina applies its own administrative procedure. Article 28 and those following open a challenge route for any user who believes they hold a better right or a legitimate interest in a name, and give the respondent 10 days to reply. The process runs on the Trámites a Distancia platform. Ten guidance criteria for identifying bad-faith registrations are set separately by Disposición 187/2023.
