Manufacture Date via IMEI?

[LilSweetLin]

Hi folks, so I saw a listing for the V30. The title says, "LG-V30-H930-64GB-Cloud-Silver-Unlocked-Smartphone-CA". The picture for the listing, however, shows the phone with a sticker that says, US998. The seller is local, here in NYC, and offered to give me the IMEI to check the manufacture date. The LG IMEI checker had no results for the number, but when I used another, it said it was the LG V30+. I used IMEI Pro, as well as the Swappa IMEI checker. When I used the Swappa checker, there was no mention of the device being the V30+; only the regular V30. How can I figure out the manufacture date of the device, via IMEI? What sites do you use, that list the date as part of the info? Is there a way to decipher it, without there being a manufacture date actually listed?
