Given name/ first name?

[maral55]

Is there any differences between the term 'Given name' and 'First name' ?

[Mrs Irons]

According to the Oxford Advanced Learner's Dictionary,
first name
(also given name especially in AmE)
noun
the name or names that were given to you when you were born, that come before your family name: His first name is Tom and his surname is Green. ◆ Please give all your first names. ◆ (BrE) to be on first-name terms with sb (= to call them by their first name as a sign of a friendly informal relationship) ◆ (AmE) to be on a first-name basis
