You can check through the dedicated electronic invoice inquiry platform by entering the invoice code, number, issuance date, invoice amount, and other information. Electronic invoices can also be checked through third-party platforms. Simply go to the WeChat Card Package and select "My Vouchers" to view your personal electronic invoice information.

I drive a lot, and checking electronic invoices at gas stations is quite simple. Usually, after refueling, I receive an SMS notification on my phone with a direct link to view the electronic invoice. If using the gas station's official app, such as PetroChina's 'Jia You Zhong Shi You' or Sinopec's service account, I can log in and go to the billing page, then enter the phone number or fuel card number used during refueling. The system automatically displays the invoice records for the day. I recommend saving them to cloud storage to prevent loss, as electronic invoices, just like paper ones, can be used for reimbursement, making things much easier. The interface may vary slightly between different gas station apps, but the process is similar, usually supporting PDF downloads or sharing via WeChat. If the SMS is delayed, it might be due to network latency or an incorrect phone number entry. You can check again later or call customer service—they're quite responsive. I've noticed that after the electronic invoice system update, it's even more convenient to check, and binding an email can enable automatic push notifications.

When I first started driving, I was confused about how to check electronic invoices. Later, I learned that the app would send a push notification after refueling, and clicking on it would bring up the detailed invoice. All I needed to do was enter my phone number for verification. Now, I make it a habit to check after each refueling to confirm the information is correct, such as whether the time and amount match. Using the WeChat mini-program to find the gas station’s official account and binding my account makes the process even simpler—just a few steps to save a copy. The advantage of electronic queries is that they eliminate the need to handle paper invoices, making it both eco-friendly and reliable, with the system automatically categorizing historical records for easy access anytime. I recommend that beginners test the process once to ensure they receive notifications, as occasional poor signal may cause delays. The platform prioritizes security, requiring only basic authentication while ensuring good privacy protection. After driving regularly, I find this feature truly hassle-free, avoiding the annoyance of lost invoices when claiming reimbursements.

I often use the APP to check electronic invoices for gas stations. The operation is straightforward. For example, log in to the CNPC app, select the query option, enter the transaction record code, and the data is instantly displayed with support for download and storage. The process is time-saving and efficient—just input verification information, and the system automatically generates accurate electronic invoices that can be emailed or synced to the cloud. Technically, the backend processing is fast, ensuring authenticity and anti-counterfeiting to avoid the risk of fraud. It is highly practical.
