This is the update I got when I tracked my passport application. Woo Hoo!
Thank you for submitting your passport application!
Your passport application locator number is xxxxxxxxx.
When you applied, you requested Routine Service and Routine Delivery of your passport. Passport Agencies use Priority Mail. This means you should receive your passport within 6 weeks from the date you applied. Depending upon how the facility where you applied forwarded your application, you should receive your passport on or about 02/10/2007.
