Checking Lottery Results with the Ticket Barcode

This article was translated by AI from the Thai original. If anything is unclear, the Thai original is the reference.

Checking lottery results using the barcode on the ticket is a method that reduces the steps of manually typing in the number. Users can open the GLO Lottery Official app and scan the Data Matrix 2D Code, or two-dimensional barcode, on the lottery ticket, so the system can match the data against the prize result database.

However, what is printed on the ticket, the data inside the code, and the details shown on the app's screen do not necessarily have to be the exact same set of information. Scanning should therefore be used to help check the result, not as proof that the ticket is genuine, and the result screen cannot be used in place of the actual physical ticket.

What is checking lottery results with the barcode on the ticket

The Government Lottery Office has publicized that ticket holders can check prize results via the GLO Lottery Official app by scanning the Data Matrix 2D Code, a two-dimensional barcode that appears on the lottery ticket. This method allows for faster number checking and reduces the risk of errors from manually entering the ticket number.

Once scanned, the app processes and uses the data it reads to check against the prize results. Users therefore do not need to type in the number every time, but should still verify that the number and draw date on the screen match the physical ticket before trusting the result shown.

Many people call this method "checking the lottery with a QR Code" out of familiarity, but in the case of the code used for scanning on the ticket, the more appropriate term is Data Matrix 2D Code, or two-dimensional barcode, because QR Code and Data Matrix are different code formats, even though both fall under the category of two-dimensional codes.

How are QR Code and Data Matrix barcodes different

The line-style barcodes commonly found on general packaging are one-dimensional codes, where data is stored through a sequence of lines and spaces. QR Code and Data Matrix, on the other hand, are two-dimensional codes that use both vertical and horizontal space.

QR Code usually has large square-shaped alignment markers at the corners, while Data Matrix has a different layout pattern for its data cells. The two names should therefore not be used interchangeably without explanation.

For scanning the Government Lottery Office ticket barcode, the code that the Government Lottery Office refers to in its publicity is the Data Matrix 2D Code, or two-dimensional barcode. Using the correct terminology helps reduce confusion about which part of the ticket needs to be scanned with the camera.

What information can you check by scanning the barcode on a lottery ticket

Scanning is used to check the prize results of that ticket through a supporting app, but the data must be separated into 3 layers: the information visible and readable on the ticket itself, the Data Matrix 2D Code, and the prize results database that the app uses to display the results.

Seeing one piece of detail appear on the screen does not mean that all the details are directly stored in the code. The app may read a certain identifier from the code, then use it to look up or match against data in the system in a separate step.

Information	Source	What can be said
6-digit ticket number	Text on the ticket or data read by the system from the code	Used for matching to check prize results
Draw date	Printed on the ticket and may be displayed in the app	Must be checked to match the actual physical ticket
Set number	Printed on the ticket	Should not be assumed that the official app will always display it
Winning status	Prize results database	Can be displayed once the results have been announced
Prize category	Prize results database	Should be re-verified against the official lottery results
Ticket authenticity	Cannot be confirmed from scanning alone	The scan result must not be used as proof that the ticket is genuine

The information in the code and the information the app displays are not the same thing

The easiest way to understand this is to view it as a continuous process. It starts with the app reading the Data Matrix 2D Code, after which the system takes what was read and checks it against the database, then displays the relevant results on the screen.

Therefore, the information that appears after scanning, such as winning status or prize category, may be data pulled from the prize results database, not all of it text embedded directly in the Data Matrix. Without technical documentation to confirm it, one should not assume on one's own exactly how much the code stores — the number, the draw, the set, the date, or other information.

Users should check three points together: the number on the ticket, the draw date, and the result the app displays. If the details do not match, one should not rush to a conclusion from the screen alone.

What information does scanning before the results are announced give you

Scanning before the results are announced cannot tell you the winning status in advance, since the system relies on results that have already been announced in order to verify anything. If the results are still in the process of being announced, the information displayed may not yet be complete or final.

The prudent choice is to wait until the announcement of results is finished, then scan again. If the result on the screen is still unclear or looks abnormal, it should be compared against the official lottery results from the Government Lottery Office's own channels.

How to scan a government lottery ticket with a mobile phone

How to scan a government lottery ticket is not complicated, but you should start by choosing the correct app and checking its details before installing. Follow these steps:

1. Open the App Store or Google Play and search for the GLO Lottery Official app

2. Check the app name, developer name, store page details, and the permissions the app requests before installing

3. Open the app and allow camera access permission when the system requests it

4. Select the menu for checking prizes, noting that the name or position of the menu may change depending on the version

5. Place the ticket flat on a surface with sufficient lighting

6. Position the Data Matrix 2D Code within the scan frame

7. Hold the phone steady and wait for the system to process it

8. Compare the numbers and draw date on the screen with the information printed on the ticket

9. If the app indicates a winning ticket, verify again against results from official channels before proceeding

Scanning lottery tickets with a mobile phone can therefore help reduce the chance of typing numbers incorrectly, but it does not eliminate the step of checking the details on the physical ticket. Users still need to be careful not to select the wrong draw, and should check that the numbers the app processes match the ticket actually in hand.

Do you need to use the GLO Lottery Official app, or can you just use the phone's camera

The camera on some phone models may be able to read two-dimensional codes, but this capability varies depending on the operating system, device model, and code format. Even if the camera successfully reads the code, that does not mean it will connect to the prize results database or display complete information.

Therefore, if you want to use the GLO Lottery Official app's function to check lottery results, you should scan directly through the tool within the app itself, and verify that it is the app officially promoted by the Government Lottery Office. You should not install a code-scanning app from an unknown developer just to read the information on the ticket, as it may request permissions or collect data beyond what is necessary.

What to do if scanning the lottery ticket fails

A failed scan can be caused by lighting conditions, focus distance, the camera, or the condition of the code on the ticket. Try fixing it in the following order:

Clean the camera lens before you start scanning
Move to an area with sufficient lighting
Avoid hand shadows and reflections on the ticket surface
Lay the ticket flat so fold creases don't overlap the Data Matrix position
Move the phone slowly in and out so the camera can find focus
Hold the camera straight toward the code, not tilted too much
Check your phone settings to make sure the app has camera permission
Close the app and reopen it if the scan screen is unresponsive
Check for and update the app to the latest version
If the code is faded, torn, or still won't scan, use the method of entering the 6-digit ticket number instead
Double-check the number and the draw date on the ticket before pressing confirm

If the ticket is damaged right at the code's position, trying to scan it repeatedly may not help. A better approach is to switch to entering the number manually, and check every digit carefully before viewing the result.

Can you check past lottery draws with a barcode?

Information on the app's listing page states that GLO Lottery Official supports checking the current draw as well as checking past draws by scanning the 2D barcode on the ticket. However, the supported time range and usage format may change depending on the app version.

If you can't check the lottery from a past barcode, you might try entering the 6-digit ticket number instead, while selecting or checking the draw date to match the actual ticket. You shouldn't assume that the time range for checking past draws is the same for number entry and code scanning, since these are different methods of use.

How far can scan results confirm a winning ticket

The results shown in the app are a channel to help check prizes. Users should compare these results against the information on the physical ticket, not just look at a message saying "winning" or "not winning" and consider the process finished right there.

After scanning, you should check at least 3 things: the 6-digit ticket number, the draw date, and the prize category. If the information does not match, you should check again by entering the number manually and compare it with the official lottery results from the website or channels operated by the Government Lottery Office.

In the case where the check result indicates a winning ticket, the original physical ticket must be kept in complete condition. It should not be discarded, torn, folded further, or have important information written over it just because the result was trusted from a single screen display. A screenshot or the result page in the app is not a substitute for the actual physical ticket when claiming prize money. Ticket holders should study the latest regulations from the Government Lottery Office before proceeding.

Can scanning the barcode check whether a ticket is genuine?

You should not conclude that a ticket is genuine simply because the app can read the code or shows a successful check result. Scanning the Data Matrix mainly serves to help check prize results, but there is not yet sufficient evidence to use a single scan as proof of a ticket's authenticity.

Likewise, scanning cannot be used to confirm who owns or holds title to that ticket. If you notice anything unusual, find mismatched information, or suspect the ticket is not valid, you should keep the ticket and inquire directly with the Government Lottery Office.

How does the official app differ from third-party lottery-checking apps

GLO Lottery Official is the app promoted by the Government Lottery Office for checking results, while third-party apps may differ in appearance, menus, data sources, and functions. Therefore, a feature of one app should not be described as a capability of another app.

Before installing, you should check the app name, developer name, reviews, permissions requested by the app, and privacy details. Avoid apps that request access to data unrelated to checking prizes, or whose developer cannot be clearly identified.

Even though third-party apps may display results quickly or offer additional menus, confirming results should primarily rely on information from the official website and app, especially when screens from different sources show inconsistent information.

Frequently asked questions

What information can the barcode on a government lottery ticket be used to check

It is used to scan through a supporting app to check that ticket's prize results. The information shown on screen may come from both what the system reads from the code and data retrieved from the prize results database, so it should not be concluded that every detail shown is stored directly in the barcode.

Is the code on the ticket a QR Code or a Data Matrix

The code that the Government Lottery Office promotes for scanning on tickets is called a Data Matrix 2D Code, or a 2-dimensional barcode. It should not be called a QR Code directly, since a QR Code and a Data Matrix are two different forms of two-dimensional codes.

If the barcode scan doesn't register, can you still check the lottery

Yes. Users can enter the 6-digit lottery number into the GLO Lottery Official app and check the draw to match the ticket. Before switching to entering the number manually, try wiping the lens, adding more light, laying the ticket flat, and checking the app's camera permission first.

Does scanning the barcode confirm that the ticket is genuine

It should not yet be concluded that way. The code being read successfully is not sufficient evidence that the ticket is genuine. If there is any doubt about the ticket's authenticity, you should ask the Government Lottery Office directly.

Can the checking result in the app be used in place of the real ticket to claim money

No. The checking result screen is meant to help verify prizes. Prize winners must keep the actual physical ticket and follow the criteria for claiming prize money set by the Government Lottery Office.

If scanning while the results are still being announced, should the result be trusted right away

You should not jump to conclusions yet, because the prize results may not have been fully announced. You should wait until the announcement is complete, then scan or check the number again through official channels.

Summary

Checking lottery results via the barcode on the ticket can be done through the GLO Lottery Official app, using the camera to scan the Data Matrix 2D Code on the ticket. There are 4 key steps: install the app from an official app store, scan the code on the ticket, check that the number and draw date match the physical ticket, and double-check against the official lottery results if a prize is won.

This method helps reduce the risk of manually typing in the wrong number, but it must be understood that the information on the ticket, the information encoded within the code, and the information the app retrieves from the prize results database are three separate things. A successful scan does not confirm that the ticket is genuine, does not establish ownership, and the result screen cannot be used in place of the physical ticket. The ticket should therefore be kept safe until every step of verification and claiming has been fully completed.
