Getting started with sports betting apps in Massachusetts is a straightforward process that requires just a few simple steps. Follow our guide to unlock the best MA sportsbook promos and set yourself up for a smooth, rewarding experience.

1. Pick a welcome offer

Massachusetts sportsbook promos come in all shapes and sizes, from bet-and-get bonuses to deposit matches. Browse the top offers on this page and choose the one that best fits your betting style.

2. Claim your promo code

Click any one of our links to activate your offer. Some Massachusetts sportsbook promos apply automatically, while others may require you to enter a code during registration. You may also be prompted to download the sportsbook app.

3. Create a new account

Fill out the registration form with your name, date of birth, address, email, and the last four digits of your Social Security number. These details are used to verify your identity and comply with Massachusetts sports betting laws.

4. Verify your identity

Before you can bet, most apps will ask you to upload a valid photo ID. This step confirms that you're at least 21 years old and physically located in Massachusetts, both of which are legal requirements for online betting.

5. Deposit funds

Make a qualifying deposit using your preferred payment method. Most sports betting apps in Massachusetts accept secure options like PayPal, Venmo, credit cards, debit cards, online banking, and Apple Pay.

6. Place a bet

Now you’re ready to bet. Make your first wager according to the promo’s terms — for example, the DraftKings welcome offer requires your first bet to have minimum odds of at least -500. Always double-check the offer details before you bet.

7. Enjoy your bonus

Once your bet settles, your bonus funds or bet credits will be added to your account. Most sports betting promos in Massachusetts come with a seven-day expiration window, so be sure to use your bonus bets before they expire.
