e-Devlet (turkiye.gov.tr) lets you handle hundreds of official procedures online without standing in line: getting documents, making inquiries, submitting applications, filing reports... All you need is an e-Devlet password — and this password is issued only to you, through an identity-verified process.
To get it the first time, you need to go to a PTT branch once; after that, everything runs online. Even if you forget your password, in most cases you can recover it without going back to PTT. You'll find the step-by-step path below. One warning up front: never share your e-Devlet password with anyone — anyone who calls and asks for your password is a scammer, without exception; official institutions don't ask for passwords over the phone.
