A first name is usually a given name and a last name is usually a surname in English-language forms. The spoken or written order of the names can differ across languages, so use the field labels and the document the form asks you to match.

Key Differences Between a First and Last Name
How They’re Assigned
While the semantic position of first and last names is a primary difference, another major distinction between the two is how they are assigned. The first name is chosen by the parents to give individuality. Whereas, the last name is passed down to carry on familial connections.
Personal Identity
The role of a first and last name in one’s personal identity influences how they perceive themselves and how they’re perceived by others. While a first name carries a sense of individuality, last names usually hold significance by carrying down a familial legacy and shared heritage.
Etiquette
There is usually a difference in formality and a certain etiquette when addressing someone by their first or last name that depends on context and cultural considerations. In formal or professional settings, it is customary to show a level of respect in interactions and refer to individuals by their last names preceded by a title, such as Mr., Mrs., or Dr. On the other hand, in more casual and familiar environments, first names are generally acceptable and considered appropriate in friendly atmospheres.
