When I was younger my parents wrote our full home address on every luggage tag in big clear capitals, and I did the same for years without thinking about it. Then a friend who travels a lot for work pointed out what a luggage tag actually tells a stranger standing next to you in the check in queue: your name, where you live, and that nobody will be home for the next week.
That was enough for me to change how we tag bags.
The point of a tag is to get a lost bag back to you. For that, an airline or a finder needs a way to contact you, not a map to your front door. So our tags now carry a surname and initial, a mobile number with the country code, and an email address. Some people write their work address instead of home, which is a sensible middle ground if you want a postal address on there at all. I also add a small note to say which bag belongs to which person, because four cases from one family look alike on a belt.
Privacy flaps help too. A lot of tags have a leather or plastic cover over the card so the details are not on display, and the airline can still lift it to read. If a tag does not have one, turning the card to face inwards against the bag does a similar job.
The outside tag is also the one most likely to go missing. Belts, loading machinery and baggage carts are hard on anything sticking out from a bag, and tags get ripped off regularly. That is why I put the same contact details on a card inside every case too, usually tucked in the lid pocket, sometimes with a copy of our trip details: the hotel name and dates. If the outside tag is lost and the airline opens the bag to identify it, the inside card is what gets it home. I learned this one from a school trip where a case arrived tagless and still found its owner because of a note inside.
Then there are the old airline stickers. The barcode tags from past flights can confuse scanners and send a bag to the wrong place, so I peel them all off, including the little barcode stickers the desk puts on the case body, before each trip. It feels fussy but it takes seconds.
Making the bag easy to recognise helps as well, mostly so nobody else walks off with it by mistake. A bright strap, a coloured tag or a ribbon on the handle makes a black case stand out, and it helps the kids spot their own bag without dragging every black suitcase off the belt. Some people take a photo of each bag and its tag before leaving home, which I now do too, because describing a lost bag to an airline is much easier with a picture.
None of it takes long. A name, a phone number and an email on the outside, the same details plus trip info on the inside, old stickers gone, and something bright to spot it by. The house address stays at home where it belongs.
