Underdog Fantasy Promo Codes & Coupons September 2025

To apply an Underdog Fantasy promo code during signup, enter the code during the registration process. After signing up for an Underdog Fantasy account, enter a promo code like "UDPROMO," "SDS," "LABS," "FANTASYPTS," or "THELINES" when prompted. After entering the code, make your first deposit, and Underdog will match 50% of your deposit amount in bonus cash, up to a maximum of $1,000. The bonus may also include a free pick'em special entry in eligible states.

Pro tip: Enter the promo code before making your first deposit, as this is when the bonus is applied to your account.

The minimum deposit required to activate the Underdog Fantasy promo code bonus is $10. When you make your first deposit of at least $10 after entering a valid promo code, Underdog will match 50% of your deposit amount in bonus cash. For example, if you deposit $10, you'll receive $5 in bonus cash. To maximize the full $1,000 bonus, you would need to deposit $2,000, as Underdog offers a 50% match on first-time deposits up to that amount.

Pro tip: Consider how much you're willing to play with and deposit accordingly to get the most value from the 50% match bonus without overextending your budget.

Underdog Fantasy has eligibility requirements that users must meet before signing up. While the exact age requirements aren't specified, fantasy sports platforms typically require users to be of legal age in their state. Check Underdog's terms of service or contact their customer support directly to confirm the age requirements for your specific state.

Pro tip: Always verify the legal age requirements for your state before attempting to sign up, as these can vary by location and may be different from sports betting age requirements.

Most fantasy sports platforms credit bonus cash to your account immediately or shortly after your qualifying deposit is processed.

Pro tip: If you don't see your bonus cash credited within 24 hours of making your qualifying deposit, contact Underdog Fantasy customer support with your deposit confirmation details.

The Underdog Fantasy promo code bonus can be used for various contests, including best ball fantasy drafts. The bonus is structured as a 50% match on your first deposit, with a minimum deposit of $10 and a maximum bonus of $1,000 (requiring a $2,000 deposit). Some promotions include additional benefits like a "Special Pick" or "New Customer FREE PICK". Note that the Pick'Em Special is not available to users in certain states including Kansas, Maryland, Michigan, Mississippi, New Hampshire, New Jersey, Ohio, and Pennsylvania.

Pro tip: Check the specific terms for the promo code you're using, as some codes may have partnerships with specific contests or additional benefits beyond the standard deposit match.

You can only use one promo code when signing up for Underdog Fantasy. The promo codes are designed for first-time users making their initial deposit. There's no indication that multiple promo codes can be stacked or combined. Each promo code (like "UDPROMO," "SDS," "LABS," "FANTASYPTS," or "THELINES") offers the same core benefit of a 50% deposit match up to $1,000, though some may include additional partner-specific perks.

Pro tip: Compare the different promo codes available before signing up to choose the one that offers the best overall value, including any partner-specific bonuses beyond the standard deposit match.

Fantasy sports platforms typically require promo codes to be entered during the registration process or before making your first deposit. If you've already created an account without using a promo code, contact Underdog Fantasy customer support directly to inquire if they can apply the code retroactively, though this is not guaranteed.

Pro tip: If you've created an account but haven't made a deposit yet, try logging out and creating a new account with a different email address to use the promo code, or contact customer support immediately before making any deposits.
