I figured out what the PCR Testing Registration Code is in the Leave Home Safe App. It was very unclear on the Leave Home Safe App what it was for, and also at the physical PCR testing site. The PCR Testing Registration Code is so you don't have to enter all your personal information at the testing site manually. If you complete the PCR Testing Registration Code, you are given a QR code, and if you go to the PCR testing site, they will scan this QR code, and it makes everything much faster. At least that's what I think when I read this news bulletin: https://www.info.gov.hk/gia/general/...2090900593.htm
For the longest time, I was scratching my head. On the Leave Home Safe App, they don't explain what the PCR Testing Registration Code is for when you enter that section.
I talked to somebody who had a family member who crossed the border. So an update on what I was told by that person:
1. I don't think you get a QR code for step 1) in my original post when you make the booking to cross the border to Shenzhen. That person told me you get a SMS message. It's when you return to HK in step 4) of my original post, is when you get a QR code.
2. In step 2) of my original post when you do the PCR test, you must do a paid PCR test, which may cost between $150 to $240 (cost may differ based on different PCR testing centers). The results of the $240 PCR test is returned faster than the $150 PCR test. From speaking to the staff at the PCR testing center, I believe you cannot do the free PCR test to cross to Shenzhen. The free PCR test is for entering local hospitals in Hong Kong, and for other purposes in Hong Kong, etc. If you cross the border to Shenzhen, you must do the paid PCR test.
3. That person also said when returning to Hong Kong, there wasn't need to do anything on WeChat. I think someone mentioned that you had to do something on WeChat, or fill some form on WeChat on the return to Hong Kong. But at least if you are returning to Hong Kong on the same day (ie. you are doing a day trip to Shenzhen) and you are not staying overnight in Shenzhen, there wasn't a need to do anything special on WeChat or fill any form on WeChat. Perhaps the step involving WeChat is for people that stay in Shenzhen/China for over 48 hours?
(BTW, if you want the proper steps officially, you should probably contact the Hong Kong Customs & Immigration Department and the corresponding official department in Shenzhen/China, because this information may not be accurate and it's heresay - it's what other people are telling me, so use this information at your own risk)
