What Is the .so Domain? Somalia's ccTLD for "So" Brands

The .so domain is the country-code top-level domain for Somalia, and it has become a recognizable pick in tech branding for one simple reason: it completes the word "so." The most famous example was Notion, whose notion.so address defined the company for years — though as of June 2026, Notion has actually moved off .so entirely, a twist that says a lot about how this suffix's real-world story keeps evolving. This page covers what .so is, its unusually turbulent registry history, the current registration rules, and how it behaves for SEO.

.so at a glance

What is .so?

.so is the ccTLD assigned to Somalia under the ISO 3166-1 country-code system. The IANA root-zone database entry for .so lists Somalia's Ministry of Post and Telecommunications as the sponsoring organization, though on-the-ground operational authority has shifted repeatedly, most recently to Somalia's National Communications Authority (NCA).

Because .so is a ccTLD, not a gTLD, it carries no ICANN registry agreement of the kind that governs .com or new gTLDs. And despite its popularity in tech branding, Google does not treat .so as generic: it is absent from Google's explicit list of ccTLDs treated as generic (which includes lookalike vanity ccTLDs like .cc, .co, and .tv), meaning a .so site is geo-targeted toward Somalia by default rather than being read as a neutral "so" suffix.

History of .so

.so has one of the most turbulent operating histories of any ccTLD:

• 1997 delegation, then collapse: first delegated on August 28, 1997 to Monolith Innovation Group, a Pittsburgh-based operator that became defunct by 1998, leaving the namespace dormant during Somalia's civil conflict.
• 2009 redelegation, 2010 relaunch: ICANN approved redelegation to Somalia's Ministry of Post and Telecommunications on February 3, 2009, and the domain officially relaunched for public registration on November 1, 2010.
• 2015 restriction: on July 8, 2015, operations transferred to the Somali Network Information Center (SONIC), which limited registration to those with a "legitimate, clear and provable connection to Somalia" — prompting several international registrars to suspend new .so sales.
• 2018 NCA takeover: on March 9, 2018, Somalia's National Communications Authority took full control from SONIC. Major registrars (GoDaddy, Rebel.com) again advertise .so with no residency requirement — but given the repeated changes, confirm current eligibility before committing to a brand.

Through all of this, .so's international reputation grew from an unrelated direction: workspace tool Notion launched on notion.so, becoming one of the most recognized "so"-ending brand hacks in tech — until Notion itself moved away from it in 2026.

How people use .so

Real, specific niches where .so shows up:

• Developer tools and platforms whose name ends in "so," such as Hiro, a Bitcoin-layer developer tools company that markets itself on hiro.so.
• Startups seeking a short, sentence-completing domain hack in the tradition Notion popularized, even after Notion's own move to .com.
• Somalia-connected institutions and organizations, the suffix's original and continuing use case, with second-level structures such as .com.so, .org.so, .edu.so, and .gov.so.

Who it's not ideal for: brands prioritizing long-term registration certainty, given the registry's documented history of eligibility changes, or anyone chasing global SEO neutrality rather than a wordplay effect.

Notable sites using .so

• hiro.so — Hiro Systems PBC's live site for its Bitcoin-layer developer tools (Chainhook, the Hiro Platform, the Stacks Blockchain API), actively maintained with 2026 blog activity and a public status page at status.hiro.so.
• notion.so — for years the definitive .so brand hack, home to workspace tool Notion. As of June 3, 2026, Notion completed a move to notion.com — an acquisition its co-founder said had been in motion since 2018 — and notion.so now redirects (HTTP 307) to notion.com. It is the clearest cautionary tale in the ccTLD-hack world: even the flagship "so" brand eventually traded the wordplay for a .com.

.so vs other domains

Choose .io or .co when you want a hack-friendly ccTLD with a stable registration history and Google's generic treatment; pick .com when brand permanence matters most, following Notion's own eventual move; reach for .so only when the wordplay is essential and you've confirmed current eligibility terms.

Why choose .so?

• Genuine, well-known wordplay. The "so"-ending hack is one of the most recognized in tech, thanks to Notion's years on notion.so.
• Live proof it still works. Hiro Systems actively runs its developer-tools business on hiro.so today.
• Distinctive positioning. A short, punchy suffix that stands out against the sea of .com and .io startups.
• Multiple second-level structures available (.com.so, .org.so, etc.) for registrants who want a categorized address.

Things to consider

• Genuine policy volatility. .so has actually restricted, then reopened, registration within the last decade — a real risk for anyone planning a long-term brand around it.
• Google geo-targets it by default. .so is not on Google's generic-ccTLD list, so a global brand should explicitly configure international targeting rather than assume neutrality.
• Even its most famous example moved on. Notion's 2026 switch to .com after eight years of trying suggests some brands view .so as a stepping stone, not a permanent home.
• No DNSSEC confirmation, and IDN is explicitly not supported — less technical flexibility than more modern ccTLD registries.

Who can register a .so domain?

Registration restrictions: confirm before you commit. 101domain's current .so registration page says the extension is open to any individual or entity worldwide. This is not how the registry has always operated: from 2015 to 2018, operator SONIC restricted registration to institutions, residents, and others with a provable connection to Somalia, causing several international registrars to pause .so sales. The namespace later reopened globally, but given this track record, verify the current rule with your registrar before building a long-term brand on .so; the IANA record can confirm the sponsoring organization but not registrant eligibility.

Domain names generally run 3 to 63 alphanumeric characters or hyphens; IDN registrations are not supported. Reserved second-level structures include .com.so, .org.so, .net.so, .edu.so, and .gov.so. Because .so is a ccTLD, it is not governed by a standard ICANN Registry Agreement — the sponsoring authority remains Somalia's Ministry of Post and Telecommunications per IANA, with the NCA holding current operational control.

.so pricing and value

.so pricing generally sits in a mid-to-premium band relative to mainstream gTLDs, reflecting its cachet as a recognized brand-hack suffix. As with most TLDs, first-year and renewal pricing differ — introductory reseller rates are not the standing renewal cost. Short or dictionary-adjacent names fitting the "so"-ending wordplay command the strongest demand and, where classified premium, higher pricing. This page intentionally quotes no figures; check current pricing with your registrar.

Reputation and email deliverability

.so does not carry a widespread spam or abuse reputation — adoption has skewed toward legitimate developer tools and brand-name wordplay rather than bulk registrations. That said, its registry instability (the 2015–2018 restriction period, multiple operator transitions) is worth weighing separately from reputation: a suffix can be technically safe for deliverability while carrying operational risk. For email deliverability, sender authentication (SPF/DKIM/DMARC) and list hygiene matter far more than the TLD itself.

Branding and naming tips

• Make the "so" completion effortless. The strongest examples (notion.so, hiro.so) land as a natural fragment — the visual/verbal snap of a short brand name plus "so."
• Have a fallback plan. Given the registry's history and Notion's own move to .com, consider registering the equivalent .com too, even if .so is your primary hack.
• Keep the pre-".so" name short. Wordplay domains lose their punch past a few syllables.
• Verify eligibility before you fall in love with a name, given the registry's documented policy changes.

Frequently asked questions

Can anyone register a .so domain?

Current registrar documentation (including GoDaddy and Rebel.com) reports no residency or local-presence requirement today, though the registry imposed a Somalia-connection requirement between 2015 and 2018. Confirm current eligibility with your registrar before registering, since .so policy has changed hands multiple times.

Does a .so domain affect SEO?

Google does not include .so on its list of ccTLDs treated as generic, so by default a .so site sends a signal that it targets Somalia rather than being read as a neutral global suffix, regardless of how the string is used in branding.

Is notion.so still used by Notion?

No. Notion switched its primary domain to notion.com in June 2026 after an eight-year effort to acquire it. As of this writing, notion.so redirects to notion.com rather than serving as the live brand domain.

Who should register a .so domain?

It suits developer tools and brands whose name naturally ends in "so," following examples like Hiro (hiro.so). It is a weaker choice for anyone who needs registration certainty, given the registry history of policy changes, or for a brand chasing global SEO neutrality.
