Everything You Need to Know Before Signing Up at 21com

Signing up at 21com is quick, but there are a few things worth knowing before you fill out the form. Nothing complicated — just the details that make for a smoother experience from day one. If you've used other sports betting platforms in Brazil before, you'll find the process here pretty familiar, with a few differences the team considers important.

Why your CPF is required at sign-up

The CPF is the tax identification number for every Brazilian citizen, and 21com requires it at registration for two main reasons. The first is identity: the CPF links your account to a real person, preventing anyone from signing up with fictitious information. The second is financial security: when you withdraw, Pix or TED transfers must be made to an account under the same CPF as your 21com account — protecting you from having your balance sent to a third party's account by mistake or fraud. The CPF also ensures that each user has only one account, a rule that protects all players by preventing the bonus system from being exploited unfairly.

Mobile sign-up: works just like on desktop

The vast majority of Brazilian bettors use their phones as their primary device — and 21com was built with that in mind. The registration form works seamlessly in your mobile browser, with fields optimized for numeric input (CPF, phone number, date of birth) and minimal scrolling required. Once your account is created, you can download the 21com app for Android or iOS and access everything in one place — Pix deposits, live betting on Brasileirão and UFC, live casino with a real dealer, and instant withdrawals — all from your phone, wherever you are.

Identity verification (KYC): when and how to complete it

You don't need to verify your identity to create an account or make your first deposit. You can deposit via Pix, bet on the Flamengo match or a UFC card, and enjoy the Live Casino before submitting any documents. KYC is only required before your first withdrawal — and the sooner you complete it, the faster the process will be when you're ready to cash out. It's straightforward: a photo of your ID (RG, CNH, or passport — front and back, clear image), a selfie holding your document, and in some cases proof of address. Verification typically takes around 30 minutes during business hours. Once approved, all future withdrawals are processed without any additional steps.

First deposit: what to expect

Once you've confirmed your email and logged in, the first step is making a deposit. Via Pix, here's how it works: go to the deposits section, enter the amount (minimum R$ 10.00), and the platform will generate a QR code or a Pix key. Open your banking app — Nubank, Itaú, Bradesco, Banco do Brasil, or any Pix-supported bank — and complete the payment. The funds appear in your 21com account within 30 seconds. For bank slips, the minimum is R$ 30.00 and processing takes up to 2 business days. Credit and debit cards are credited immediately in most cases, with a minimum of R$ 20.00. 21com also accepts PicPay and Mercado Pago for those who prefer digital wallets.

Setting responsible gambling limits from the start

21com recommends that every user set deposit and betting limits right after their first login — not because you'll have a problem, but because it's a healthy habit that puts you in control from day one. You choose the limit that works for your entertainment budget: R$ 50.00 a week, R$ 200.00 a month — whatever suits you. Once a limit is set, the platform automatically prevents you from depositing beyond it within that period, regardless of payment method. Reductions take effect immediately; increases have a 7-day waiting period to protect you from impulsive decisions. You can find these settings under "Responsible Gambling" in your account settings.

Account security: essential tips

Once your account is set up, a few basic security habits go a long way. Use a strong, unique password for 21com — ideally a mix of uppercase and lowercase letters, numbers, and symbols that you don't use anywhere else. Enable two-factor authentication (2FA) in your security settings: it adds an extra layer of protection by requiring a confirmation on your phone every time you log in, so even if someone has your password, they can't access your account without your device. Never share your login credentials with anyone — including anyone claiming to be "21com support." Our support team will never ask for your full password. If you notice any suspicious activity, use the account lock option in your settings right away and reach out via live chat.

Under-18s: strictly prohibited

21com is a platform exclusively for users aged 18 and over. The registration form requires an age declaration, and the identity verification (KYC) process confirms your date of birth against an official ID. Accounts created by minors are closed immediately upon detection, and the associated CPF is blocked from future registrations. If you are a parent or guardian, make sure your device does not remain logged in to 21com where children or teenagers can access it.
