Yes—for a UK passport application, every part of the name requested by the form should be included. HM Passport Office guidance says the name on the application must match the name on the applicant’s UK or overseas supporting document. Its paper-application instructions also ask for the person’s surname and first and middle names.
How to check the name
Before submitting, the applicant should:
- Check the name on the supporting document.
- Compare its surname and first and middle names with the corresponding fields on the application.
- Follow the field labels used by the particular application form rather than entering only part of the name.
The cited paper-application guidance uses separate fields for “surname” and “first and middle names.” Other application routes may present the name fields differently, so the relevant form and its current instructions remain important.
What the applicant must still confirm
The two cited passages do not explain how every possible discrepancy should be resolved. If the supporting document and passport show different name components, or if the applicant is unsure which field a particular component belongs in, that person must confirm the correct treatment under the current official instructions before submitting the application.
This answer concerns UK passport applications. The supplied official material does not establish equivalent name-entry rules for another country’s passport or for a different type of travel document.
