Three-letter handles

The scarcest shape a name can take. All 17,576 possible three-letter .com domains were registered by 1997, and not one has been created since.

The supply is fixed and small

There are 46,656 possible three-character strings using letters and digits, and 17,576 using letters alone. No mechanism exists to make another.

Every top sale is short

Across every namespace with a public price record, the biggest sales are one to three characters or a single short word.
