Short answer: Not always. Coral and Ladbrokes share an operator, LC International, and a welcome offer may be refused if you already hold an account at the sister brand. Check each offer's terms on existing customers.
What a sister site is
A casino run by the same licensed operator as another. They share systems, so the operator knows you are the same person.
How to find sister sites
Search the operator's account number on the Gambling Commission's public register; the entry lists every domain it runs.
What is shared
Often payment exclusions, terms and self-exclusion. A self-exclusion at one should apply at the other.
Among the five
Only Coral and Ladbrokes are sisters. PlayOJO, Casumo and 10bet each have a separate operator.
