Ok, so this is weird....
Just made my login.gov account, which went smoothly enough. I provided my PASS ID number, and it pulled up my GE membership under my account just fine. But this is where things start getting odd.
I clicked on the 'Update Documents' link on the right to make sure everything was up to date before applying for my GE renewal, and every single date on every document is off by one day! My date of birth on my passport and DL is one day earlier than the actual date. Similarly, the issuance and expiration dates on my passport, as well as the expiration date on my DL are off by a day (listed as being one day earlier, just like on my date of birth under both documents).
Anybody else run into this issue?
