OKX Sign-Up FAQ: Verification Codes, Nationality, Invite Code, Rejections
Wherever sign-up gets stuck, jump to that question. We've gathered the most-asked OKX (formerly OKEx — same company) sign-up questions on one page — from verification codes not arriving and wrong nationality, to whether you can add invite code OK2707 later, what to do if KYC is rejected, and how to recover lost 2FA — 18 in all. Read whichever one hits your problem; no need to start from the top. One thing up front: invite code OK2707 can only be entered at sign-up, not added later.
If you want the full sign-up steps rather than single-point Q&A, start with the full sign-up guide; this page is all about "what to do when you're stuck."
01Sign-Up
From sign-up to buying crypto, roughly how long does it take?
Registering the account itself is only a few screens; for the identity verification review time, see “How long does KYC verification take?” below; P2P deposits depend on how fast the merchant releases. Going from zero account to your first coin mostly comes down to how long the verification review takes.
What if the verification code never arrives?
Email code missing? Look in spam and promotions first. SMS code missing? Check the country code, wait a minute or two, then resend. If nothing still arrives, try another network. It's mostly a delay or a block by the carrier/mailbox, not a problem with the account itself.
I forgot to enter invite code OK2707 at sign-up — can I add it later?
No. Per OKX's official Help Center, registration has to be completed with the referral code already entered for the referral relationship to exist — it can't be added or changed after sign-up. So if you haven't registered yet, make sure to enter OK2707 on the same step where you type your email (OKX's steps note “insert Referral code (if any)” right there) before submitting — it decides whether the fees on your qualifying trades come back to you. For how to enter it and confirm it took, see How to Enter Invite Code OK2707.
What if I picked the wrong country / region?
The Country/Region box at sign-up asks where you live now. OKX says it usually isn't your nationality or the country that issued your passport, so it doesn't have to match your ID; the nationality in identity verification is what follows your document. If the region you picked doesn't reflect where you actually live and you haven't verified yet, check account settings to see if you can change it; if it already affects verification, contact official support.
How many OKX accounts can one person have?
A verified account is tied to your identity, so one person can usually have only one KYC-verified account. Don't try to register multiples to farm promotions — it easily triggers risk controls and account limits. Just use one account normally.
Does it cost money to register on OKX?
Registering and verifying are free. The only money you spend is in two places: the cost of depositing and buying crypto (the P2P spread or Express Buy channel fee), and trading fees. Part of the latter comes back if you bind invite code OK2707 at sign-up and the trade qualifies — see How Fees Work.
The page keeps failing / submitting does nothing — what do I do?
First confirm you're on the official domain
okx.com (don't enter via unfamiliar links); then switch networks, clear cache, or try a different browser/app. Still nothing? Come back a bit later — sometimes it's temporary peak-time turbulence.Can people in my country register and use it? What are the risks?
Crypto rules vary by country — check your local laws before you act. In some places, personal participation carries legal or tax implications, so decide carefully based on your own situation, at your own risk. This site only provides information and is not encouragement or advice of any kind.
02KYC Verification
How long does KYC verification take?
OKX's English Help Center says it reviews applications within 24 hours of submission. After submitting, wait patiently — don't resubmit over and over. A clear ID photo and matching information make a rejection far less likely.
What do I do if KYC is rejected?
Rejections are usually one of these: glare/blur on the ID photo, corners cut off, info not matching what you entered, or face recognition failing. Re-shoot as prompted — lay the ID flat, even lighting, no glare; do face recognition in a bright spot, no beauty filter — and resubmit. For a case-by-case breakdown, see How to pass OKX KYC with a passport.
Can I verify with a passport? Is a local ID required?
Yes. OKX's KYC supports a passport and various other government IDs (the exact list is what the verification page shows for your region) — it's not limited to a local ID. The nationality you enter follows your ID; the region you picked at sign-up follows where you live, and the two can differ.
Face recognition keeps failing — what do I do?
Move to a well-lit spot, take off your mask and glasses, skip the beauty-filter camera, and keep your face steady in the frame. A laggy network can also fail it, so use a stable connection. A try or two usually does it.
03Account & Login
What if I forget my login password?
Tap "Forgot password" on the login page, verify via the email or phone you bound at sign-up, and reset it. This is exactly the advantage an exchange account has over a Web3 wallet — a forgotten password is recoverable.
I switched phones — how do I keep logging in?
Install the OKX app on the new phone and log in with your username/password + verification code. But note: if you turned on Google Authenticator (2FA), migrate or unbind the authenticator before switching phones, or you'll get stuck at the 2FA step. See the next item.
I lost my Google Authenticator (2FA) / it's gone after changing phones — what now?
If you saved the backup key from when you bound it, just re-add it in the authenticator on the new device; if you didn't, you'll go through the official identity verification / unbinding process, which usually needs account info and a security check — more of a hassle. This is why the security setup guide keeps stressing copying down the backup key when binding.
Where do I find official live support / help?
Find the "Help Center / Live Support" entry inside the OKX app or on
okx.com. Remember: official support won't DM you and won't ask for your password, verification code, or seed phrase. Anyone proactively adding you and asking for these is a scammer.04Age limits and what to do after signing up
Can minors register?
No. Exchanges require users to be of legal age (usually 18+), and KYC verifies the age on your ID — minors can't pass.
After registering, what's the first thing to do?
Do account security first: turn on 2FA with Google Authenticator and set an anti-phishing code, then complete KYC and deposit. While there's no money in the account yet, spend a few minutes locking it down to save yourself trouble later. Steps in Post-Sign-Up Security.
📋 If sign-up gets stuck
OKX's Help Center lists the desktop order like this: pick your country/region and accept the terms, then enter your email — OKX's own steps mark this screen with “insert Referral code (if any)”, and that's where OK2707 goes. A six-digit code is sent to your inbox and has to be entered within 10 minutes; it sometimes lands in the promotions or spam folder first, so check there. After that you verify your phone number, and setting the password comes last. The "forgot password" flow likewise resets fine via email verification. The takeaway: many "can't register" cases are really a delayed code or one sitting in spam, not a problem with the account. Timings per item are subject to your network and the verification queue at the time.
