Withdrawal Address Whitelist
Address whitelist · Withdrawal whitelist · Address book · Withdrawal address registration · Personal wallet registration
Registering and verifying a withdrawal address, and whose it is, before sending coins out; Korean exchanges in effect require it.
Simple explanation
Background: Abroad, an address whitelist is usually an optional security switch. In Korea, registering the receiving address (출금 주소 등록) and having it checked is part of every withdrawal, because the Travel Rule requires exchanges to know whether coins go to another exchange's customer or to the sender's own wallet.
A withdrawal address whitelist means registering in advance the addresses you will send to, and allowing withdrawals only to those. Many overseas exchanges let you turn this on or off as a security feature: with it on, someone who gets into your account cannot simply send your coins to their own address. At Korean exchanges it is less an option than a step you cannot skip, because regulation requires them to know which exchange and which person is receiving, or that a wallet really is yours.
That regulation is the Travel Rule. Under Korea's Specific Financial Information Act, since March 2022 a Korean exchange sending ₩1,000,000 (about $714) or more of crypto to another exchange must pass sender and recipient information to the receiving exchange. To do that it needs to know, before the withdrawal, where the coins are going and to whom, so exchanges have customers register withdrawal addresses and then verify them. If the destination is an exchange linked through a Travel Rule system, the recipient's details are checked with that exchange; if it is a personal wallet, you prove it is yours. Withdrawals to overseas exchanges that are not linked may be blocked or need extra checks.
Amounts under ₩1,000,000 now need registration too. Upbit from February 13, 2025, and Bithumb from April 1, 2025, block withdrawals under ₩1,000,000 whose destination has not been verified, allowing them only to addresses at Travel Rule-linked exchanges or to addresses registered and verified in advance. Before that, splitting a transfer into pieces below ₩1,000,000 let people send to personal wallets or abroad without any check, and this "split sending" had been criticised as a loophole.
How you register differs by exchange. Typically you open the withdrawal address menu, enter the coin, the network and the address (plus a memo or tag where needed), choose whether the destination is an exchange or a personal wallet, and pass an extra authentication step. For a personal wallet you must prove ownership in the way the exchange specifies; which wallets are supported and how ownership is proved vary by exchange and change often. The same coin may need a separate entry for each network, verification can take time, and a registration can be refused. Check each exchange's own guide and notices for the exact steps.
Registration also protects your coins. Someone who logs into your account still cannot withdraw straight away to an address that is not registered, and adding a new one takes extra authentication. So be suspicious of anyone who, citing a "security check", "profit withdrawal" or "account protection", asks you to register an address they give you as your withdrawal address, or to install a remote-control app. Registration never involves handing over your seed phrase either. And a registered address is only as good as what you entered: register a wrong address, and whatever you send to it is a mistaken deposit.
The rules are set to tighten. A decree amending the Specific Financial Information Act's enforcement rules, approved by Korea's cabinet on August 11, 2026, scraps the ₩1,000,000 threshold so the Travel Rule covers transfers of any size, and sorts transfers to overseas exchanges and personal wallets by the counterparty's risk. Transfers to low-risk overseas exchanges are to be allowed; other overseas exchanges and personal wallets only when sender and recipient are the same person (your own account or your own wallet); and dealings with places rated high-risk banned. It is due to take effect six months after promulgation, in early 2027. Separately, to go with the amended Foreign Exchange Transactions Act due to take effect on December 3, 2026, a decree that would have transfers between Korean exchanges and overseas exchanges or personal wallets reported to the Bank of Korea's foreign-exchange data system was pre-announced in October 2026. This is general information as of early November 2026, not legal advice; check exchange notices and official announcements for when and how the rules apply.
For kimchi premium arbitrage, an overseas exchange address that has not been registered and verified in advance means you cannot send coins the moment a premium opens, and the premium may shrink while you wait. Whether the overseas exchange appears on your Korean exchange's Travel Rule list can decide where you are able to send at all. These steps make moving coins between Korea and abroad slow and cumbersome, which is one of the reasons often given for why the premium does not vanish at once.
CoinGaja does not handle withdrawal addresses, but Exchange notices gathers the four Korean exchanges' notices, where withdrawal-policy and Travel Rule link changes appear, and the deposit and withdrawal suspension page shows whether withdrawals of a coin are open. The Kimchi Premium Calculator takes withdrawal fees off too and shows what is actually left.
Example
With Tether at ₩1,400, the ₩1,000,000 (about $714) Travel Rule line → 1,000,000 ÷ 1,400 = about 714.29 USDT
Withdrawing 700 USDT (₩980,000, $700) → under ₩1,000,000, but since February 13, 2025, Upbit sends it only to registered and verified addresses or Travel Rule-linked exchanges
Withdrawing 800 USDT (₩1,120,000, $800) → ₩1,000,000 or more, so sender and recipient information goes to the receiving exchange with it (the Travel Rule)
Split ₩3,000,000 (about $2,140) into ₩990,000 × 3 + ₩30,000 → still none of it can go to an unregistered, unverified address, and once the new decree applies every transfer falls under the Travel Rule regardless of size
Planning to move ₩10,000,000 (about $7,100) at a +3.00% premium, but the premium falls to +1.00% while you wait for registration → expected gain ₩300,000 → ₩100,000 (about $214 → $71)
