Creating an account at 55aa is the fastest registration process you'll find on any betting platform in Brazil. We only ask for basic information to properly identify you — name, CPF, date of birth, email, and mobile number — plus a secure password to protect your account. No lengthy forms with dozens of fields, and no documents required before you can do anything on the platform.
Your CPF is required because it is the way that 55aa must ensure that each person holds only one account — required both by law and to prevent promotional abuse. It's the same reason Pix transactions in Brazil require a CPF: it's every citizen's unique identifier within the national financial system.
After registering, you'll receive a confirmation email within seconds. One click on the link and your account is active. Your first deposit can be made via Pix with any Brazilian bank — Nubank, Itaú, Bradesco, Banco do Brasil, Caixa, Inter, C6 Bank, or any other institution participating in the Banco Central's Pix system. Your balance appears instantly and the welcome bonus from 55aa is applied automatically — no code needed.
Identity verification (KYC) is not required to place bets — you can deposit, bet, and enjoy the platform without submitting any documents. KYC is requested before your first withdrawal, which is standard practice on all serious betting platforms in Brazil. The process is straightforward: a selfie with your ID and proof of address. Approval takes up to 72 business hours in most cases.
Important tip: use your real CPF and accurate personal details when registering. Incorrect information can delay your first withdrawal — and worse, result in your bonus balance being cancelled if the discrepancy is flagged during KYC. It's much easier to get it right from the start.
Registration requirements
100% up to R$ 500.00 on your first deposit. No tricks — see exactly how to make the most of it.
The welcome bonus from 55aa is applied automatically on your first Pix deposit after registration — no promo code needed, no need to contact support. You deposit, the system doubles the amount up to R$ 500.00, and the bonus shows up in your account's bonus balance.
Practical example: you've just created your account at 55aa and make a Pix payment of R$ 100.00 as your first deposit. The system applies a 100% match, giving you R$ 100.00 in real balance + R$ 100.00 in bonus balance = R$ 200.00 to play with. If you deposit R$ 500.00, you get R$ 500.00 in real balance + R$ 500.00 in bonus = R$ 1,000.00 available.
Your real balance is yours — withdraw it whenever you want, no strings attached. Your bonus balance must meet the 10x rollover requirement before it converts into real withdrawable funds. That means with R$ 100.00 in bonus, you need to place R$ 1,000.00 in eligible bets to convert the bonus into real balance. Sports bets with odds above 1.50 and slots both contribute 100% toward the rollover.
How to get the most out of your bonus: bet on Brasileirão teams with odds above 1.50 or use your bonus on Pragmatic Play slots. Slots contribute 100% toward the rollover and come with high RTP. You have 30 days from bonus activation to complete the rollover — plenty of time for regular users of the platform.
