Airline baggage systems use a range of codes and numbers to identify checked luggage, record who issued a baggage tag and describe what has happened when a bag is delayed, mishandled or damaged.
These codes are not all part of the same system. A 10-digit baggage tag number, a three-digit Baggage Tag Issuer Code and a WorldTracer Reason for Loss code each communicate different information.
This page brings our airline baggage code guides together so you can quickly find the code, number or baggage reference you are trying to understand.

What Are Airline Baggage Codes?
“Airline baggage codes” is a useful umbrella term for several identifiers used during baggage handling. Some identify a particular checked bag, some identify the organisation that issued its tag, and others record the reason baggage was mishandled.
Understanding which type of code you are looking at is the first step. The number printed on your baggage receipt does not serve the same purpose as an operational code entered into a delayed-baggage file.
Airline Baggage Codes and Numbers at a Glance
| Code or Number | What It Is Used For |
|---|---|
| 10-digit baggage tag number | Identifies an individual piece of checked baggage |
| BTIC | Three-digit Baggage Tag Issuer Code forming part of the baggage tag number |
| Reason for Loss code | Records why baggage was mishandled in WorldTracer |
| PIR/file reference | Identifies a delayed or damaged baggage report or case rather than the physical bag itself |
Airline Baggage Tag Numbers
When checked baggage is accepted at the airport, the tag attached to it carries a standard identification number. The IATA baggage tag Licence Plate Number contains 10 digits.
The number can be divided into a leading digit, a three-digit Baggage Tag Issuer Code and a six-digit serial number. Together, these identify the checked item within baggage-handling systems.
Our guide to airline baggage tag numbers explains how the 10 digits are structured, what the leading digit can mean, how rush baggage tags differ and why you should keep the baggage receipt after check-in.
The IATA Baggage Tag Issuer Code (BTIC)
BTIC means Baggage Tag Issuer Code. It is a three-digit numeric code contained within the standard 10-digit baggage tag number.
The name is important: the code identifies the baggage tag issuer. It should not simply be interpreted as “the airline operating my flight”, particularly when a journey involves codeshares or connecting airlines.
Our dedicated guide to the IATA Baggage Tag Issuer Code explains where the BTIC appears in a baggage number and how it works with the tag’s serial number.
WorldTracer Lost and Mishandled Baggage Codes
WorldTracer uses Reason for Loss codes to record why baggage has been mishandled. Despite the name, these codes are not limited to luggage that has permanently disappeared.
The standard categories cover issues including check-in and tagging errors, baggage that was not loaded, loading and offloading mistakes, arrival problems, transfer baggage, airport-related causes, miscellaneous mishandling, damage and pilferage.
Our guide to IATA WorldTracer lost baggage codes explains the current categories and secondary codes and also highlights differences between current information and older baggage-code lists.
WorldTracer Reason for Loss Categories
| Primary Code | Category |
|---|---|
| 10 | Original station check-in |
| 20 | Origin station failed to load |
| 30 | Loading and offloading |
| 40 | Arrival station |
| 50 | Transfer station |
| 60 | Airport — general |
| 70 | Miscellaneous |
| 80 | Damage |
| 90 | Pilferage |
Individual secondary codes provide more detail about the recorded cause. Airlines or handlers may also use customised descriptions or codes, so check directly with the airline if a code in your baggage file does not match a general reference.
Baggage Tag Number vs Lost Baggage File Reference
These references are easy to confuse but they perform different jobs.
Your baggage tag number identifies the checked item. If the bag does not arrive and you report it, the airline or baggage service may create a separate delayed-baggage report and file reference.
Keep both references. The original tag helps identify the physical baggage, while the baggage tracing or case reference identifies the report created after something went wrong.
What Is a Property Irregularity Report?
A Property Irregularity Report (PIR) is associated with reporting baggage that has not arrived as expected or has been damaged. The resulting file or reference is separate from the baggage tag number attached when the item was originally checked.
If you need to report baggage, follow the airline or baggage handler’s instructions at the airport or through its designated reporting system. Keep the reference it gives you together with your original baggage receipt.
Why Keep Your Baggage Tag Receipt?
The small baggage receipt given to you at check-in can become important if a suitcase does not arrive. It contains the identification information linked to the checked item.
- Keep every baggage receipt until all checked items have been collected.
- If you check several bags, record which tag belongs to which suitcase.
- Take a photograph of the luggage before handing it over.
- Photograph the baggage receipt as a backup.
- Keep any delayed-baggage case reference separately.
- Use the exact reference requested by the airline’s tracking system rather than guessing which part of the number it needs.
You should store backup copies of anything you backup in a Google Drive folder so you always have access if you have an internet connection.
Are Baggage Codes the Same as Airline SSR Codes?
No. Baggage identification and mishandling codes should not be confused with the Special Service Request codes used to communicate passenger requirements.
SSR codes can be used for matters such as disability assistance, medical requirements, special meals or other passenger services. Baggage tag and WorldTracer codes perform different operational functions.
You can learn more about SSR codes in our guide to passanger SSR codes used by airlines.

Airline Baggage Codes FAQs
How many digits are in an IATA baggage tag number?
The standard baggage tag Licence Plate Number contains 10 digits, including a leading digit, three-digit Baggage Tag Issuer Code and six-digit serial number.
What does BTIC mean?
BTIC means Baggage Tag Issuer Code. It is the three-digit issuer code contained within the standard baggage tag number.
What are WorldTracer Reason for Loss codes?
They are codes used in baggage files to indicate why a bag was mishandled. Categories cover issues such as check-in, loading, transfers, arrival, damage and pilferage.
Is a PIR number the same as my baggage tag number?
No. The baggage tag number identifies the checked bag. A PIR or baggage-file reference identifies the report created when baggage is delayed or damaged.
Should I keep my baggage tag receipt?
Yes. Keep it until every checked item has been collected. The identification information can be important if a bag is delayed or does not arrive.
Are baggage codes the same as airline disability codes?
No. Baggage codes identify luggage or record baggage-handling information. Airline disability and other SSR codes communicate passenger service or assistance information.
Understanding airline baggage codes can make luggage tags, baggage allowances and lost luggage updates feel less confusing. Keep your baggage receipts until your bags are safely back with you, and ask the airline to explain any unfamiliar reference. Knowing which details to check can help you feel more prepared if something does not go to plan.
