Every Day Is Tag Day is observed worldwide every first Saturday of April, initiated by the American Humane Society. This annual awareness campaign focuses on educating pet owners about the significance of pet tags and identification. Participants are encouraged to ensure their pets wear ID tags, which typically include the pet's name, owner's name, phone number, and address. The campaign highlights the importance of visible ID tags in complementing microchipping, as tags allow anyone who finds a lost pet to contact the owner directly. With approximately 10 million pets lost or stolen in the U.S. each year, the campaign aims to improve the chances of reuniting pets with their owners, especially for those in shelters without identification. Additionally, it emphasizes that even indoor pets should have proper identification, as they can accidentally escape.
