Welcome bonuses are limited to one per household, IP address, or device. Existing customers do not qualify. That's the rule at every major US sportsbook, and it's enforced more aggressively than most bettors expect. If you're sharing a home with someone who already claimed a welcome offer, you may be out of luck — even if you've never opened an account before. Understanding exactly how these restrictions work can save you from a voided bonus or, worse, a permanently closed account.
How do sportsbooks detect multiple accounts in the same household?
Sportsbooks track IP addresses, device fingerprints, shared payment methods, and matching personal details like name, address, and date of birth. If two accounts share the same home Wi-Fi during registration, the system flags it. Shared debit cards or bank accounts are another common tripwire. You don't have to do anything overtly suspicious — just registering from the same router as a family member who already has an account can trigger a review.
What gets your bonus voided?
Promo code not entered at sign-up is one of the most common reasons. Most sportsbooks will not honor a welcome offer if the code is applied after account creation. There's no override process. You either entered it during registration or you didn't. Other common reasons for voiding include placing the qualifying bet below the minimum odds threshold, using an excluded deposit method, and triggering the household flag. Check which deposit methods qualify for sportsbook offers before you fund your account — some payment types are excluded from bonus eligibility outright.
Attempting to claim multiple welcome bonuses using a family member's account violates T&Cs and can result in permanent account closure. That's not a warning — that's the standard enforcement outcome. A closed account means losing any remaining balance, not just the bonus.
Should you deposit more to unlock a bigger bonus?
No. Depositing more than planned to unlock a larger bonus is exactly the behavior that large headline bonus numbers are designed to trigger. Read the terms before depositing a single dollar. A $1,500 second-chance offer only pays out as bonus bets on a loss — it's not $1,500 in cash. See the best second-chance bet offers at US sportsbooks for a current breakdown of what each book actually delivers.
How do the major sportsbooks compare on household and promo rules?
| Sportsbook | Welcome offer type | One-per-household rule | Promo code required at sign-up | Bonus bet expiry window |
|---|---|---|---|---|
| FanDuel | Bet & Get (guaranteed bonus bets) | Yes — one per household/IP/device | Yes — must be entered at registration | 7–30 days |
| DraftKings | Deposit match / Bet & Get | Yes — one per household/IP/device | Yes — cannot be applied retroactively | 7–30 days |
| BetMGM | Second-chance bet up to $1,500 | Yes — one per household/IP/device | Yes — must be entered at registration | 7–30 days |
For a detailed look at one specific book's terms, see the FanDuel sportsbook offer breakdown. And before you enter any code, read how sportsbook promo codes work and why they matter — skipping that step is one of the most avoidable ways to lose a bonus.
What should you do if you live with an existing customer?
Contact customer support before registering. Explain the situation in writing and get a response in writing. Some sportsbooks will manually verify separate identities for household members — but there's no guarantee, and policies vary by operator and state. Availability and bonus eligibility depend on your state's regulations; sports betting is legal in 39 states plus D.C. and Puerto Rico as of 2026, but offer terms differ by jurisdiction.
