Airline-approved luggage tags: what you need to know

The airline’s own tag is the one that matters most

Before worrying about your own tag, understand what the airline does: at check-in, a barcoded luggage tag — technically a PTC (Passenger Tag Coupon) — is attached to every checked bag. That tag is what the airline’s sorting system reads at every checkpoint. It’s the reason your bag ends up where it does. Anything that obscures, damages or detaches from that barcode is a problem.

Your personal luggage tag is — from the airline's perspective — cosmetic. It helps a human identify your bag on a carousel. It does nothing to help the airline route it. This is why no airline publishes a list of approved personal tags: the only hard requirement is that the airline barcode remains visible and intact. And if your bag does go missing, see our step-by-step recovery guides for the major UK, US and European airports.

Tags with batteries: where airlines draw the line

The main friction point for “smart” luggage tags is batteries. Active transmission tags — those that broadcast a Bluetooth, cellular or RFID signal — fall into different regulatory categories depending on the airline and the route. The concern isn’t the radio itself (low-power Bluetooth is generally harmless near avionics) but the lithium battery that powers it, which is subject to strict IATA regulations on spare batteries in checked vs. carry-on baggage. For a comparison of QR tags against Bluetooth trackers like AirTag, see our guide.

Most major airlines — including British Airways, Virgin Atlantic, United, American, Delta and Lufthansa — have updated their policies in recent years to explicitly permit Bluetooth trackers like AirTags in checked baggage. The key caveat is that the battery must be in the device (not loose), and the device must be switched off or in airplane mode on some carriers. Always check your specific airline’s current policy before packing an active tracker in a checked bag.

Cellular tags with their own data plan and ongoing transmission tend to face more scrutiny, both from airlines (due to radio emission rules) and from customs agencies (due to serial number registration requirements in some countries). A QR tag, by contrast, contains no battery and no radio — so there is quite literally nothing for an airline to restrict.

Physical tag materials: what causes problems

Most personal luggage tags are made from one of four materials: leather, plastic/PVC, metal, or fabric. All are generally fine for carry-on bags. For checked bags, the issue isn’t safety — it’s equipment damage.

• Leather tags — unlikely to cause conveyor issues. A leather loop tag is probably the safest choice for frequent checked-bag travellers who want something durable and unobtrusive.
• Plastic / vinyl tags— standard and universally accepted. Flexible enough not to catch on anything. BagBeacon’s vinyl QR sticker is this category.
• Rigid plastic tags — acceptable in most cases, but a tag with a protruding buckle or clip could theoretically catch on conveyor mechanisms. Smooth-edged designs are preferable.
• Metal tags — acceptable in principle, but heavier and more likely to scratch or dent bag-handling equipment if they come loose. A solid metal tag with a leather or fabric loop and smooth surfaces is generally fine. Tags with sharp edges or carabiner clips are more questionable. BagBeacon uses printed plastic and vinyl, which are flexible and lowest-risk for conveyor equipment.
• Fabric tags with plastic hardware — broadly fine. Like leather, fabric is unlikely to damage equipment and is commonly seen on luggage.

RFID and NFC: do you need it, and does it matter?

Most QR luggage tags don’t contain an RFID chip at all — they’re printed codes that point to a web page. If a tag advertises “RFID blocking” as a feature, that refers to blocking unauthorized reads of an embedded chip — which most QR tags don’t have.

For airline RFID bags — where the airline embeds an RFID chip in its own tag so that sorting scanners can read it throughout the journey — the read range is specific to the airline’s infrastructure. An RFID-blocking layer on your personal tag would not interfere with an airline RFID bag scan: the blocking material is designed to defeat general-purpose readers at a distance, not the dedicated close-range scanners airports use.

In short: RFID features on a personal luggage tag are largely irrelevant to airline operations. Choose based on whether you actually want the functionality (e.g. tap-to-read from a smartphone) rather than airline compatibility concerns. For a comparison of QR vs NFC tags specifically, see BagBeacon vs NFC luggage tags.

What to do if your tag causes a problem at the gate

Security or gate staff very occasionally question unusual tags — usually when something looks like it might contain a battery or when a metal tag is large enough to be visible on an X-ray. The practical steps are the same in either case:

• Stay calm and cooperative. This is almost always a five-minute conversation, not a security incident.
• Explain what it is.“It’s a QR luggage tag — no battery, no radio, it’s just a printed code on the outside of the bag.”
• Show the tag separately if asked. Most gate staff will accept a visual inspection and move on.
• If told to remove it, remove it. A tag is not worth missing your flight over. You can reattach it at arrivals or complain afterwards.
• Note the airline and incident detail. If this happened at a security checkpoint rather than the airline gate, the relevant complaint is to the airport authority, not the airline.

The practical summary

The vast majority of luggage tags — leather, vinyl, flexible plastic, fabric — cause zero friction at any airline. The situations where a tag becomes a problem are narrow and specific: a metal tag with protruding hardware that catches on conveyor equipment, or a tag containing an active radio transmitter that the airline hasn’t approved.

If you want the maximum compatibility with zero airline policy checking, choose a passive QR tag with no battery. If you want an AirTag for its network-based location features, keep it in the checked bag (where airlines have broadly approved it) and confirm your carrier’s current policy before you fly. For carry-on bags, any standard tag is fine. For a full comparison, see our guide to BagBeacon vs Apple AirTag.

FAQ

Can I use an AirTag or Bluetooth tracker as a luggage tag?

Yes — but with conditions. Most airlines now permit Bluetooth trackers in checked baggage following years of ambiguity. The issue isn’t the radio (which operates at low power) but the lithium battery inside them. Individual airline policies vary, so always check before you fly. Apple’s own guidance and most airline policies explicitly permit AirTags in checked bags. They are not permitted as carry-on accessories in some contexts, so confirm with your carrier.

Do QR luggage tags cause problems at airport security?

No. QR luggage tags are passive — they’re printed codes that do nothing until someone scans them. There’s no transmission, no battery, no RFID chip. Security scanners read barcodes on airline tags; they don’t interact with QR luggage tags in any way. A QR tag attached to the outside of your bag is functionally identical to a paper luggage tag from the scanner’s perspective.

What about RFID-blocking luggage tags?

RFID-blocking tags are designed to prevent unauthorized reads of the chip inside an RFID-enabled passport or credit card. Most QR luggage tags don’t contain an RFID chip at all, so the RFID-blocking feature is irrelevant to them. If your tag does include an RFID chip for airline tracking, the blocking layer would theoretically interfere with it — but airline RFID bags are read by dedicated scanners at close range, not the general-purpose readers RFID-blocking is designed to defeat.

Do airlines have official approved luggage tag lists?

No major airline publishes a formal approved list of luggage tags. What airlines do have is a set of restrictions: nothing that obstructs the airline barcode on the bag, nothing with active transmission that violates their electronics policy, nothing that damages handling equipment. The practical test is whether a tag would interfere with the airline’s own identification and routing system. Most tags — leather loops, simple plastic tags, QR sticker tags — pass without question.

Will a metal tag damage airport conveyor systems?

Metal tags with sharp edges or protruding parts can theoretically damage conveyor belt equipment, which is one reason many airlines prefer flexible materials. A solid metal tag with a smooth finish, like BagBeacon’s stainless steel tag, is generally fine in practice — but the safest choice for checked bags is a flexible tag that can’t catch on anything. For carry-on or personal items, metal is less of a concern.
