renewing a US passport, the official steps (check the date)

what to actually do, not the 45 blog posts about it. rules change, so check the date on this before you rely on it for a trip.

01
Check you're actually eligible to renew
not your first passport, not older than 15 years, not damaged, no name change without paperwork - otherwise it's Form DS-11 in person
02
Decide: online or by mail
03
Online: create an account through the State Department's renewal system
this part trips people up, it's a MyTravelGov account, not the passport application itself
04
Online: fill out the application and upload your photo
05
By mail: get Form DS-82
fill it out online and print it, download the PDF, or pick one up at an acceptance facility
06
By mail: get a passport photo taken and include it
07
Pay the fee either way
the amount changes most years, check the date on whatever number you're reading
08
By mail only: send in the application, photo, fee, and your current passport
yes, your actual passport - it gets mailed back separately after the new one arrives
09
Track your status online once it's submitted
10
Check your destination's 6-month validity rule before you book anything
some countries and airlines deny boarding under that window, and it's never the airline that tells you first
