How to buy coins on exchanges: deposits, KYC, limits

What you need before you start

Nothing about buying coins is complicated once the paperwork clears. The paperwork is the whole exercise. Have these ready before you open a new account:

• A government-issued ID: passport, driver's license, or national ID card, unexpired.
• A phone number and email address you actually control, since both get a verification code.
• Proof of address for higher verification tiers: a recent utility bill or bank statement with your name and address visible.
• A funding source already active: a bank account for transfers, a card that permits crypto purchases, or an existing wallet if you're moving coins rather than buying fresh.
• Confirmation that your country of residence isn't on the exchange's restricted list. Binance's list is long and includes American Samoa, Canada, Cuba, Cyprus, Guam, Indonesia, India, Iran, Japan, North Korea, Northern Mariana Islands, Philippines, Puerto Rico, Russia, Singapore, Thailand, Ukraine (Crimea Region incl. Donetsk, Luhansk, Zaporizhzhia and Kherson as well as the Crimea Peninsula), United States Minor Outlying Islands, USA, Vietnam, Virgin Islands (U.S.), Malaysia, Netherlands, United Arab Emirates, United Kingdom..

Skip any of these and you'll stop mid-process, usually right after uploading a blurry ID photo.

Takeaway: verification documents matter more than the deposit method you eventually pick.

Steps to buy coins on a centralized exchange

The sequence is the same across most exchanges, Binance included. The differences show up in how long each step takes, not in the order.

1. Register. Sign up with an email or phone number and set a password. This gets you a shell account with no withdrawal or purchase rights yet.
2. Verify identity (KYC). Upload the ID document, take a selfie, and wait. Approval times vary; treat anything instant as a bonus, not a baseline.
3. Add a payment method. Link a bank account for transfers or a card for instant buys. Card purchases usually process faster and cost more.
4. Deposit funds. Minimum deposit amounts vary by currency and method, so check the specific asset's page before sending anything. Minimum deposit amounts vary by currency and method
5. Place the order. Use an instant buy for speed at a fee of up to around 2%, or a spot order for lower cost at a maker fee of 0.100% or taker fee of 0.100%.
6. Move the coins, or don't. Leave them on the exchange for convenience or withdraw to a wallet you control. That's a separate decision with its own fees.

Takeaway: the account creation is fast; the identity check is the actual bottleneck.

A note on instant buy versus spot orders

Instant buy is a convenience fee dressed up as a feature. You're paying up to up to around 2% for the privilege of not placing a limit order. If the amount is small, the difference in dollar terms won't matter. If it's not small, it will.

Fees and limits that apply

Here's what actually costs money once you're through verification.

The gap between spot fees and instant buy fees is the whole story here. A taker fee of 0.100% on a spot order is a rounding error next to a card purchase fee that can run up to up to around 2%. If you're buying a small amount once, the difference is trivial. If you're doing this repeatedly, it compounds.

Country access is a separate limit from fees, and it's binary: you're either allowed on or you're not. Binance's restricted list covers American Samoa, Canada, Cuba, Cyprus, Guam, Indonesia, India, Iran, Japan, North Korea, Northern Mariana Islands, Philippines, Puerto Rico, Russia, Singapore, Thailand, Ukraine (Crimea Region incl. Donetsk, Luhansk, Zaporizhzhia and Kherson as well as the Crimea Peninsula), United States Minor Outlying Islands, USA, Vietnam, Virgin Islands (U.S.), Malaysia, Netherlands, United Arab Emirates, United Kingdom.. Separately, the Binance app lists Countries/Regions where the Binance App is supported: El Salvador as a supported country/region for its app specifically — a narrower claim than general platform availability, and worth checking before assuming your country is fine just because it's not on the restricted list.

Takeaway: fee differences are a matter of percentage points; country access is a matter of yes or no.

Common problems and fixes

Most support tickets on exchanges fall into a handful of repeat categories.

KYC rejected. Usually a blurry photo, a name mismatch between the ID and the account, or an expired document. Fix: resubmit with a sharper image and make sure the name field matches the ID exactly, including middle names.

Deposit not credited. Often the wrong network was selected when sending crypto, or the transaction hasn't reached enough confirmations yet. Fix: check the transaction hash on a block explorer before contacting support, and confirm the network matched what the exchange's deposit page specified.

Country blocked. If your country appears on the restricted list, the account will not function regardless of what documents you provide. Binance's restricted list includes American Samoa, Canada, Cuba, Cyprus, Guam, Indonesia, India, Iran, Japan, North Korea, Northern Mariana Islands, Philippines, Puerto Rico, Russia, Singapore, Thailand, Ukraine (Crimea Region incl. Donetsk, Luhansk, Zaporizhzhia and Kherson as well as the Crimea Peninsula), United States Minor Outlying Islands, USA, Vietnam, Virgin Islands (U.S.), Malaysia, Netherlands, United Arab Emirates, United Kingdom.. There's no support ticket that fixes this; it's a policy decision, not a technical one.

Card declined. Some banks block card transactions tagged as crypto-related regardless of the exchange. Fix: contact the bank first, then fall back to a bank transfer if the card keeps failing.

Fees eating a small purchase. An instant buy at up to up to around 2% on a small amount can feel disproportionate. Fix: switch to a spot order once verification is complete; the maker and taker fees (0.100% and 0.100%) are considerably lower.

Takeaway: most problems are either a documentation mismatch or a jurisdiction issue, and only one of those is fixable by the user.
