Usernames are commonly grouped into three types: all-letters ("zed"), all-digits ("420"), and mixed (a combination of both). It's a real, practical distinction — not just a labeling choice — because it changes both how a handle reads and how it's typically priced.
This is also the basis of the "letters/chars/digits" filter tags you'll see on listings — a quick way to narrow down exactly which type you're after.
All-letter, pronounceable handles are generally the most sought-after tier, but a strong all-digit combination (like a repeating or meaningful number) can still price well.
Open the vault, pick a listed username, and DM the contact handle shown on the site to arrange payment — there's no cart/checkout, it's a direct conversation with the seller.
