What documents do I need to provide for a passport application?

When applying for a passport, you need to provide specific documents to support your application. Primary proof of identity can be established using your current passport, a certified copy of a birth or adoption certificate, a certificate of naturalization, or a valid travel document. Additionally, you'll need to submit two identical photos meeting specific requirements. Proof of name change, if applicable, must also be submitted, such as a marriage or civil partnership certificate. It's crucial to provide adequate proof of your British nationality, whether by submitting your previous passport or a naturalization certificate. Lastly, you'll need to include supportive documents proving your eligibility and entitlement. This can vary depending on individual circumstances, so it's worth consulting the HM Passport Office website or contacting their helpline for detailed guidance tailored to your specific needs.
