discuss Who has a single letter domain name? Ask grok, the answer is that there are only 800-1000.

[superidn]

I was curious 6 or 7 years ago, so I bought a single letter domain name, and the renewal price was $38. Now I realize that there are actually very few people in the world who have single-letter domain names, so I think it is very valuable for collection now because things are rare. I wonder how many people in this forum have single letter domain names.
As of September 2025, there are about 1,591 top-level domains (TLDs): 1,249 generic TLDs (gTLDs, e.g., .com, .xyz) and 316 country code TLDs (ccTLDs, e.g., .cn, .us), all using Latin letters. About 192 TLDs allow single-letter second-level domains (e.g., a.com), including 132 gTLDs (traditional ones like .com restrict new registrations, with rare cases like x.com; new gTLDs are more open) and 60 ccTLDs (e.g., .ai, .de). Around 800-1,000 single-letter domains (a-z) are registered: 200 in gTLDs, 600-700 in ccTLDs. Many ccTLDs have none registered due to reservations or non-release.
Single-letter domains resemble CryptoPunks (NFT collectibles), with up to 26 per TLD, totaling a scarce set.

The count of "possible" single‑letter domains includes many that are reserved, blocked, or never released.

Added to that, value also depends on demand, not just scarcity. Market value varies drastically by TLD, language, and commercial relevance. A single‑letter .com is vastly different from a single‑letter in an obscure new gTLD. Scarcity across all TLDs is not the same as scarcity in desirable TLDs.

Comparing single‑letter domains to CryptoPunks oversimplifies. NFTs are purely speculative digital collectibles with no functional utility beyond ownership. Domains have functional value (web presence, branding), and their market dynamics are tied to business use, not just collectibility.

Renewal cost is set by the registry and has no direct correlation to resale value. Some worthless domains have high renewals, and some valuable ones have low renewals.

How does one even get a single letter domain name in 2025 for say a new extension? I don't see any official domain rulebooks and guidebooks!

In the past 5 years, NameBio show 30 sales of single letter names. Here is a link to list:

Is price the registration price? What I'm asking is if you are Joe Nobody and you see a new extension, let's call it for the sake of argument, .lol, how do you even register a single domain letter with that extension? I'm sure Joe Nobody, if they are doing pre-registration whatever that means, can't just say I preregister j.lol. I'm guessing the domian extension enlists their short list of people with money first and if they say yes, they get the single letter domain. Am I wrong? If no, how does one register a single letter name, assuming they have the money?

 

[Bob Hawkes]

No anyone is on equal footing to go to a registrar and register. One of the easiest to see what is going on with registry premium is Porkbun. Say I head there, and search for single letter V. Many pages of results. This little part of it shows that the .wiki can be registered for less than $500 but you will pay that every year. The .lat is almost $2200 and that is every year. The .fit is for sale on aftermarket. There are page after page of results for each single letter or number.

I have few. I put one on sale which ultra premium A. I don't know if letter A comes for sale, if ever often. The others are secret, for now

Most are at a Premium cost, for instance, these were still available on Sep 5th 2025 when I ran a batch check: https://www.namepros.com/threads/ml...r-domains-premium-registration-costs.1362078/

But then, you can probably score a 1-Letter or 1-Digit for cheaper than that from someone that already has one that's a standard renewal cost. Maybe someone that has been holding for 5 to 10-years, hasn't been able to find the right buyer at the price they wanted yet, and needs some liquid cash.

Out of curiosity as you seem to know the answers to everything, that's a compliment not sarcasm, what approximately is the cheapest you could get a single non IDM letter domain as of today?

@superidn renewal cost is pretty standard.

If you have a Trustee in Ukraine, 0.ua is still available for registration for $35 at regery

Added note: well, maybe not for long if someone else see's this public post and resides in Ukraine or has a Trustee there already.

This forum seems exclusive to those who believe so-called IDN ("International Domain Names") are bogus or flawed because the letters don't exist directly on the standard Anglo-American keyboard. But many European languages use single-letters they type directly (ß German eszett is an example). IDN punycode (xn--???) is simply an alternate bonus input method. Daily use of German, Swedish, French, etc., (and of course Greek, Chinese, Hindi, etc.) involves characters beyond English. Sometimes these look like accented English characters, but of course Greek, Russian, Chinese, etc. generally use different alphabets - and we should expect alternative input methods to increase (vocal, eye-tracking, or brain-computer interface).

Just for perspective, i wanted to add 3 keyboard layouts so readers understand what you mean.

German

Chinese

Arabic

Thanks Eric !

For German, that's the ß (eszett) right next to the zero key
