Four-Digit ENS Names: How the NFT Trading Market Works
Numeric.eth names from 0000 to 9999 trade as a collectible set, and their prices can jump when attention returns. Here is how the market works, what moves it, and how to avoid its common traps.
By the DappsAtlas editorial team · Updated

What is a four-digit ENS name?
A four-digit ENS name is a.eth name made only of four numerals, such as 0420.eth or 7777.eth. There are exactly 10,000 of them, from 0000 to 9999. Because the full set is finite, short, and easy to remember, collectors treat it as a category in its own right, often called the 10k Club.
ENS, the Ethereum Name Service, maps readable names to wallet addresses and other records. Instead of sending funds to a long hexadecimal address, a person can send to a short name. Numeric names add a second appeal: they are language-neutral, simple to type on any keyboard, and cannot be confused with most spelling variants.
The market for these names works like other collectible sets:
- Fixed supply. No more than 10,000 exist, and many are held long term.
- Pattern premiums. Repeating digits, palindromes, sequences and culturally meaningful numbers tend to attract more interest than random combinations.
- Community identity. Holders often join clubs and display the name as a profile badge, which adds a social layer to the price.
Note that a name's usefulness and its trading price are separate things. A name can work well as a wallet label and still have no active buyers. Conversely, prices can rise for reasons that have little to do with how the name is used. The rest of this guide explains what sits underneath those price moves and how to look at them calmly.
Why do numeric ENS names attract traders?
Several features make numeric names attractive to speculators and collectors at the same time.
Scarcity you can count. Ten thousand names is a small, fully visible universe. Anyone can check how many are listed, how many have changed hands recently, and which are still unregistered or expired. That clarity makes the category easy to talk about and easy to compare with other collections.
Easy entry compared with three-digit names. Three-digit names are even scarcer, so they usually sit in a higher tier. Four-digit names are the next step down, which makes them a popular first purchase for people who want a short numeric identity.
Low per-item price relative to many art collections. In many market phases, a four-digit name has cost far less than a top profile-picture NFT. That lowers the barrier to participation, though it does not reduce risk.
Utility narrative. Holders can use the name for receiving funds, as a subdomain parent, or as a profile on apps that read ENS records. Supporters argue this gives the names a reason to exist beyond speculation.
Social signalling. Wallets and social apps display ENS names, so a short numeric name is visible to others.
None of these factors guarantees demand. Interest in the category rises and falls with the wider NFT and Ethereum market, and attention can move to other themes quickly. Treat the appeal as a reason for the market to exist, not as evidence that any particular price is justified.
How ownership works: token, registrant and records
Understanding the ownership model helps you avoid buying something different from what you expected.
A.eth name is registered through the ENS system and represented as a token. In the standard form, the name is an ERC-721 NFT. Whoever holds that token is the registrant, the true owner. Two other roles matter:
- Controller. The address allowed to manage records and subnames. By default it is the registrant, but it can be changed.
- Resolver and records. The settings that say which wallet address the name points to, plus optional profile data.
Setting the name to point at your wallet does not make you the owner. The token is what counts. A buyer who receives the token but forgets to update the records may find the name still pointing to the previous owner's address, which can misdirect payments.
Wrapped names. ENS also offers the Name Wrapper, which turns a name into an ERC-1155 token and adds fuses. Fuses are permissions that, once burned, cannot be undone, such as preventing the name from being unwrapped or restricting subname creation. Some collectors like the added guarantees. Others stay unwrapped for simplicity or to avoid compatibility quirks.
Before buying, confirm whether the listing is wrapped, which fuses are set, who the registrant is, and what the records point to. After buying, update the records and consider setting the name as your primary name if you want it shown in apps.
What causes a surge in four-digit name trading?
Numeric ENS markets are known for sudden bursts of activity. Several forces usually sit behind them.
- Broader NFT sentiment. When general NFT interest rises, collectors rotate into categories with simple stories and low entry prices. Numeric names often get attention early in such rotations.
- Social momentum. A prominent wallet buying, a community club announcing activity, or a trend among well-known accounts can pull in followers.
- Floor sweeps. Buyers who purchase many of the cheapest listings at once push the lowest price up and make the category look active.
- Clustered listings and bids. Collectors place offers above the floor, which can reset price expectations quickly.
- Wash trading. The same party can trade a name back and forth to create the look of demand. This is a known issue on NFT markets and can inflate volume figures.
- Renewal and expiry cycles. Lapsed names re-entering the pool can change supply at the margin.
A surge on its own tells you little. The questions to ask are whether many different wallets are buying, whether sales continue after the first spike, and whether the floor holds when volume cools. Surges in thin markets often reverse as quickly as they appear, and late buyers are the ones most exposed when that happens.
For evergreen purposes, do not rely on a past spike to infer what will happen next. Check live data instead, as described later in this guide.
How trading works and where names change hands
Four-digit ENS names are traded peer to peer on NFT marketplaces that support ENS tokens, with OpenSea being the best-known venue for the category. Other venues and aggregators may also list them. ENS itself provides a manager app for registering, renewing and transferring names, but it is not a trading venue.
There are a few ways a sale can happen:
- Fixed-price listing. The seller sets a price and the buyer pays it.
- Offer or bid. A buyer places an offer on a specific name or on the collection, and the owner can accept.
- Direct transfer. Two parties agree off-platform and move the token themselves. This carries more risk, since no marketplace protections apply.
- Fresh registration or post-expiry registration. Anyone can register an unregistered name by paying the registration fee. Names that expire go through a grace period and a temporary premium before opening to everyone.
Some tools take a different route to liquidity. Doma fractionalizes web3 domains into tradable tokens, which changes how a holder can sell or share exposure. NFTX turns NFT collections into vault-backed tokens to allow instant sales at pool prices, though availability depends on which collections have vaults. Check each protocol's current supported assets before assuming it handles ENS names.
Remember that on-chain sales carry gas costs, and marketplaces take fees and may enforce creator or protocol charges. Factor these in when comparing a listing price with the real cost of acquiring or exiting a position.
How to judge the value of a four-digit name
There is no single correct price for a four-digit name. Experienced traders look at several factors together and compare against recent sales of similar names.
| Factor | What to check |
|---|---|
| Pattern | Repeating digits, palindromes, ascending sequences, round numbers and culturally meaningful numbers usually draw more interest than random strings |
| Recent comparable sales | Sales of similar patterns over the past weeks, not asking prices alone |
| Expiry date | A name close to expiry carries an immediate renewal cost for the buyer |
| Wrapped or unwrapped | Different buyer pools and different fuse settings |
| Sales history | Many quick trades between few wallets can signal inflated volume |
| Records and subnames | Existing subnames or records may need cleanup after transfer |
| Listing depth | How many similar names are listed and at what spread |
Two habits help. First, compare sold prices, not listed prices. Asking prices can sit far above where anything clears. Second, look at how long comparable names took to sell. A name that needs months to find a buyer has lower liquidity than its listing price suggests.
For any digit pattern that seems cheap relative to others, ask why. It may reflect a short renewal window, a messy history, or simply a lack of demand for that pattern. Valuation here is partly subjective, and community taste shifts over time.
Costs, renewals and what happens at expiry
Owning an ENS name is not a one-time purchase. Names are registered for a chosen number of years and must be renewed to stay yours.
Registration and renewal fees. ENS charges an annual fee that depends on name length. Shorter names cost more per year than longer ones, and the fee tiers are set by the ENS DAO. Fees are quoted in US dollars and paid in ETH. Check the ENS manager app for the current rate for four-character names rather than relying on a number from an article.
Expiry. If a name is not renewed, it enters a grace period during which the previous owner can still renew. After that, a temporary premium applies for new registrants, which decays over time until the name is available at the normal fee. If you buy a name close to expiry, you take on the renewal responsibility immediately.
Other costs to count:
- Network gas for registration, renewal, transfers and record updates.
- Marketplace fees on sales.
- Gas for any approvals or listings.
Renewals can often be paid by anyone, which means a third party could extend your name, but you should not count on that. Set a calendar reminder well ahead of expiry and consider registering for multiple years if you plan to hold.
A practical rule is to add the cost of renewal to your purchase price when comparing with other options. A name with years remaining may justify a higher price than one due to lapse soon.
Main risks of trading numeric ENS names
Four-digit names combine a speculative market with technical details that trip up newcomers. The main risks are:
- Price risk. Values can fall sharply after a surge, and there is no guarantee of resale.
- Liquidity risk. The market is small. Some names have few buyers at any given time.
- Inflated volume. Wash trading and self-dealing can make activity look stronger than it is.
- Expiry loss. Forgetting to renew can mean losing the name, and a rival may register it.
- Lookalike and phishing risk. Scammers create fake listings, spoofed marketplace pages and unsolicited offers. A fake collection or a different token with a similar title is a common trick.
- Approval scams. Signing a malicious setApprovalForAll request can let a thief move every ENS name and NFT in your wallet.
- Wrapping and fuse mistakes. Burning a fuse is permanent. Doing so by accident can lock you out of actions you wanted.
- Tax and legal duties. Many places tax NFT gains or treat them under specific rules. Check local requirements or ask a qualified adviser.
For defence, keep high-value names in a hardware-backed wallet that you do not use for browsing airdrops or minting. Use a separate wallet for experimentation. Read every signature request, revoke stale approvals periodically, and never share a seed phrase. This guide is general information, not financial advice.
A step-by-step checklist before you buy
Use this sequence before you pay for any four-digit name.
- Confirm the name and token. Check the exact digits and the contract on the marketplace. Make sure it is the official ENS registrar or Name Wrapper token, not a lookalike.
- Read the ENS manager record. Look at the registrant, controller, expiry date and whether the name is wrapped. Note any burned fuses.
- Check sales history. Look for repeated trades among a small number of wallets and for sale prices well below or above the current listing.
- Compare recent sold prices for similar patterns across more than one venue.
- Add up total cost. Include price, gas, marketplace fee and the next renewal.
- Use a clean wallet. Keep only what you need in the wallet that signs the purchase, and use a hardware wallet for storage.
- After purchase, set your records. Point the name to your address, and set it as your primary name if wanted.
- Plan renewal. Calendar the expiry and consider extending for several years.
- Review approvals. Revoke any marketplace permissions you no longer need.
If a deal feels rushed, comes from an unsolicited message, or asks you to move the name off-platform, stop. Legitimate trades rarely need urgency. Walking away costs nothing, while a bad transfer is usually irreversible.
Where to check current data and alternatives
Because this market moves fast, live data matters more than any figure in an article. Prices, floor levels, volume and the number of active listings change constantly, so check them yourself at the time you decide.
Where to look:
- The ENS manager app for a name's registrant, expiry date, wrapped status and the current fee for its length.
- Major NFT marketplaces for the ENS collection floor, recent sales and offers.
- NFT analytics dashboards that track volume and unique buyers and sellers, which help separate real demand from wash trading.
- Community channels for the numeric clubs for pattern conventions and general sentiment, treated cautiously since participants often hold names themselves.
- ENS governance forums for fee changes, registrar updates or policy proposals that could affect holders.
If you want exposure to domains through a different structure, Doma's fractionalized domain tokens and NFTX's vault-backed collection tokens represent different approaches to liquidity. TokenWorks' NFTStrategy tokens use trading fees to buy, relist and burn NFTs, and are aimed at experienced, risk-tolerant users. Each has its own smart-contract and market risks, and none is an endorsement. Confirm what each currently supports before using it.
Finally, decide your limit before you start, size positions to what you can afford to lose, and be skeptical of anyone promising returns.
Frequently asked questions
How many four-digit ENS names are there?
There are 10,000 possible names, from 0000.eth to 9999.eth. Traders group them as the 10k Club, and it sits alongside smaller sets such as the three-digit 999 Club. Each name is a single unique token, so supply is fixed by the digits themselves.
Do four-digit ENS names expire?
Yes. Every.eth name is registered with an annual fee and must be renewed. If it lapses, it enters a grace period and then can be registered by anyone, so a buyer inherits the renewal duty and should check the expiry date before paying.
Can I count on being able to resell a four-digit name?
Not reliably. Prices depend on demand for the whole category, and a single name can sit unsold for long stretches. Treat any price history as a record of past sales, not a promise of future resale, and never spend money you cannot afford to lose.
What does it mean for an ENS name to be wrapped?
Wrapping converts a name into an ERC-1155 token through ENS's Name Wrapper and enables extra permission controls called fuses. Many collectors prefer unwrapped names for simplicity, and some buyers want wrapped ones. Check which form a listing is in and whether any fuses are burned before buying.
How do I check whether a four-digit name's price is real?
Check the sales history and the expiry date on the ENS app, confirm the contract and token ID on the marketplace, and compare recent sales on more than one venue. Be cautious of unusually high volume on a name that has traded repeatedly between a few wallets.
