Start with the licence number
Where you can play starts with who is allowed to let you play. In Great Britain that means a licence from the UK Gambling Commission, and the licence number is the quickest thing to check on any sportsbook page.
Numbers differ in length, so copy them whole rather than trusting your memory. 10Bet publishes 043173-R-322899-023 and also a Great Britain entry, 43173. 888sport lists 039028-R-319297-014, and Bar One Racing Bar 1 Betting lists 056516-R-332750-007.
Take that number to the public register and check the licence holder's name and status before you sign up. Brands like 10Bet publish enough detail for you to do this in a couple of minutes, and the same habit works for every brand in our list.
Several sites, the same licence holder
Regional sportsbooks often share a single licence, and that is easy to miss. bet365 publishes 055149-R-331499-004, and Bet365 Argentina, Bet365 BR, Bet365 EE and bet365 Espana carry the same number as 055149-R-331499-004, 055149-R-331499-004, 055149-R-331499-004 and 055149-R-331499-004.
The betano family works in the same way: betano lists 039576-R-319370-028, Betano BG lists 039576-R-319370-028 and Betano Chile lists 039576-R-319370-028.
A shared number means you are dealing with the same licence holder, so the name on your screen tells you less than the number does. Local market rules still differ, so keep reading the terms on the site you actually sign up to.
Regulators outside Great Britain
Regulators elsewhere run their own schemes, so a licence from one country does not cover you in another. Sweden's Spelinspektionen shows up on several entries: bet365 at Kommersiellt online 710308134, atg at Kommersiellt vadhållning 710308135 and 10Bet at 22Si2218.
10Bet also lists an Irish licence, GRAI-0917-RB-26-0001, from the Gambling Regulatory Authority of Ireland. Bet On Alfa lists B005 from the National Betting Authority of Cyprus, while Amazon Betting lists 77962 from the Seychelles Licensing Authority.
The question to ask is simple: does your own gambling authority appear? If it does not, you have less local protection and more reason to read the withdrawal terms and limit tools closely.
The country lists that decide where you cannot play
A licence tells you who may serve you. A country list tells you where you are turned away, and that is where many new readers get caught out.
20Bet blocks BY, FR and NL and Bet223 Bet2africa blocks GB, US and FR. Both lists are long, which hints at the markets each brand serves.
1xBit blocks US, GB and NL and 1xBet Partners blocks US and AU. The list for 1win is shorter: KZ and RU. A short list is not an open door, because payment methods and local rules decide the rest.
bet365 shows the opposite pattern, with wide reach and a long block list at AF, AS and AO, while Bet365 Argentina blocks CN and IN, Bet365 BR blocks CN and Bet365 EE blocks CN. Read the list for the site you will use, not for the parent brand. The detail behind these entries is worth reading again in our 1win, 1xBit, 1xBet Partners and 20Bet reviews.
Bonus terms, deposits and withdrawal times
Licensing and country checks tell you whether a sportsbook can take your money. They say nothing about the money side, so read that with the same care.
Look for the wagering condition attached to any bonus, the minimum deposit for the payment method you prefer, and the withdrawal time for the payout route you would use. Write each answer in the same column for every brand on your shortlist.
A headline bonus with a long wagering condition is worth less than the headline suggests, and a quick withdrawal paired with a high minimum deposit suits a particular budget rather than a general one. Values only compare when the conditions behind them match.
If a terms page leaves any of this unclear, treat it as a question to ask before you deposit rather than something to discover afterwards. Our Betting apps roundup is handy for comparing how apps handle deposits, while the Betting exchanges list suits readers who prefer to back and lay.
Safer play, limits and adults only
Whatever you pick, play is for adults only, and the safety tools matter more than any bonus offer.
Before you deposit, find the deposit limit, the session reminder and the self-exclusion route. Setting them takes a moment, while doing it later, in the middle of a session, is far harder.
Set a limit you can afford to lose, and treat a win as a reason to stop rather than a reason to keep going. Never borrow to bet, and never use money meant for rent, food or bills.
If betting starts to feel like a chore you cannot skip, or you begin hiding losses from people close to you, close the account and use a self-exclusion block. A gambling support service in your country can help you take the next step.
A checklist you can reuse
Work the same order for every brand: licence number, your own regulator, the country list for the site you will use, wagering condition, minimum deposit, withdrawal time, then limits and self-exclusion.
Write the answers side by side and the differences stop hiding. Keep the numbers to hand so you can re-check them if a site rewords its terms.
