Is it a crime to open other people's mail

In most jurisdictions, opening someone else's mail without their permission is considered a criminal offense. This is because mail is considered private property, and opening it without consent is a violation of the recipient's privacy and property rights.

In the United States, for example, the United States Postal Service (USPS) has a specific law that prohibits the unauthorized opening of mail. The law, known as 18 U.S.C. § 1702, makes it a felony to "open, detain, or conceal" any letter or package that is being transported by the USPS.

Similarly, in Canada, the Criminal Code prohibits the unauthorized opening of mail, and is punishable by up to 10 years in prison.

In the United Kingdom, the Theft Act 1968 makes it an offense to "steal" mail, which includes opening someone else's mail without their permission.
