Two-letter domains (LL)

Two-letter domains explained: how many exist, why every LL.com is taken, famous sales like We.com and FB.com, and tips for buying two-letter names.

Two-letter domains, called LL in investor shorthand, are among the most prized names on the internet. They're short, easy to type, and perfect for initials and acronyms, which is why big companies hold most of the .com versions.

How many are there?

• Letters only (LL): 26 × 26 = 676 combinations, from AA to ZZ.
• Letters and numbers mixed: 36 × 36 = 1,296 combinations.
• Numbers only (NN): 100 combinations, from 00 to 99.

Every two-letter .com has been registered for years. Most belong to large companies, organizations or long-time investors, and they rarely come up for sale.

Famous two-letter sales

• We.com sold for $8 million in 2015, one of the top cash domain sales on record.
• FB.com was bought by Facebook for a reported $8.5 million in 2010.

Why they're valuable

• Acronyms: thousands of companies are known by two letters, such as GE, HP or LG.
• Short links and apps: two letters are perfect for short URLs and app branding.
• Scarcity: only 676 letter-only .coms exist, and they're all taken.

Two letters in other endings

In endings like .co, .io, .ai and many country codes, two-letter names are still sometimes available as premium registrations or on the aftermarket, at much lower prices than .com. Be aware that two-letter combinations that match country codes can be restricted in some endings.

Tips for buying

1. Check comparable sales on NameBio, filtered to two-letter names in the same ending.
2. Use a broker for .com. Owners rarely respond to cold offers.
3. Always use escrow, and confirm ownership with a WHOIS lookup.
