Check the validity maths
Count three months beyond the e-visa's expiry, not beyond your return date.

Documents and requirements
The Azerbaijan e-visa asks for little paperwork, but every item has to be exact. Here is the Baku visa checklist we use for every client.
Baku visa checklist
Based on the conditions of the official e-visa portal.
Requirements for embassy visas and residence permits are different. See Baku embassy and Azerbaijan TRC.
The passport scan
The official conditions list an unreadable passport scan among the reasons an e-visa can be refused, and a refused fee is not refunded.
We check every scan before submission. A good scan is in colour, flat, evenly lit and shows all four edges of the photo page including the machine-readable lines at the bottom.

Detail that matters
Count three months beyond the e-visa's expiry, not beyond your return date.
Type every name exactly as printed in the passport, in the right fields.
The e-visa and any request from the portal go to that address.
Turn on international online payments with your bank before applying.
Your arrival date should agree with your flight booking.
Stays of more than 15 days need registration of your place of stay with the State Migration Service.
Requirement questions
The online e-visa form itself does not ask for one, but carrying proof of funds when you travel is sensible.
The e-visa uses your passport photo page scan. Embassy visas and residence permits have their own photo requirements.
At least three months beyond the expiry date of the e-visa.
