The time period for which a passport is valid depends on the age when you were first issued the passport. If you were 16 and older, the passport is valid for 10 years from the date of issue. If you were 15 or younger, the passport is valid for five years from the date of issue. For easy reference, the specific expiration date will be designated on your passport next to your picture.
When renewing your passport, allow enough time for the process to go through, especially if you have imminent travel plans. The Department of State, the issuing agency for passports, suggests renewing your passport at least nine months before its expiration. This will allow for a seamless renewal. Certain countries and airlines require a passport to be valid months beyond the departure date of your trip. Familiarize yourself with individual policies relevant to your travel plans.
You can renew your passport by mail if you have your passport, if it was issued within the last 15 years, you were 16 or older when an original was issued and if you have the same name or legal documentation of a name change. You'll need to mail in a DS-82 form, available from the Department of State's website, along with your most recent passport, two identical passport photos and a passport fee. Send the information in a padded envelope, and it won't hurt to send it through certified mail so there is a record it arrived. Expedited service is available for an additional fee.
If you have changed your name since the issuance of your most recent passport, you'll need to include a certified copy of the name change documentation (marriage certificate or court order). If you do not have this information, you will need to apply in person for renewal.
You will need to apply for a renewal passport in person if you do not have your most recent passport, if your passport was issued more than 15 years ago, if your passport is damaged or if you were younger than 16 when an original was issued. You will need to submit form DS-11 along with proof of U.S. citizenship. Acceptable documents include a previous passport, not torn or damaged, a certified copy of your birth certificate, a certificate of citizenship, a naturalization certificate or a Consular Report of Birth Abroad or Certification of Birth (refer to the Department of State for more detailed information). Also, submit identification such as a valid driver's license or as stated the previous passport, along with an application fee and two identical passport photos. Check with the Department of State for facilities near your location about how to renew your passport.
Passport regulations are changed and updated periodically. Be sure to check with a passport facility for the most recent information, particularly if you have any questions, issues or specific circumstances that may affect your application or renewal.
