Vérifier vs. contrôler vs. checker
The French verbs vérifier, contrôler, and checker all translate to the English concept of checking or verifying the state and accuracy of something. However, they are used in different contexts depending on the level of formality, the presence of an authority figure, and whether the language used is standard or colloquial.
Vérifier
This is the most standard, neutral, and versatile verb used to confirm the accuracy, truth, or current state of something. You use vérifier in everyday situations when you want to make sure that a fact is correct, a task is done, or an item is in order without implying any legal or authoritative inspection.

(I need to check if I locked the door properly.)

(He checked the tire pressure before hitting the road.)
Contrôler
This verb implies a more official, formal, or systematic inspection. It is commonly associated with authority figures, regulations, security, or strict quality assurance protocols. While it translates to checking, it carries the weight of an official audit or inspection.

Checker
This is an informal anglicism borrowed from English, heavily used in modern spoken French and corporate slang. It means taking a quick look at something or verifying a minor detail casually. You should only use checker in relaxed, informal settings or among friends and colleagues.

Summary
To summarize, use vérifier as your standard, everyday word for making sure something is correct. Choose contrôler when referring to an official inspection conducted by an authority figure or a strict quality process. Finally, use checker only in informal conversations to describe a quick, casual verification.
