Other mistake: Dom drives his Dodge Charger out of the Antonov's cargo hold - which is filled with, well, cargo - through the nose of the plane which was already on fire while he was still in it - and yet there isn't a single dent on his car before he loses control and rolls it.
Other mistake: When Hobbs and Letty jump from the plane they jump down to the car, but earlier when Shaw's girlfriend fell out of the door she was blown backwards, this should apply to Hobbs and Letty too.
Other mistake: Hobbs asks to see all footage from "in and around Waterloo station." The technician is then asked to "bring up cameras 58 through 62." 5 cameras to cover the entirety of that area is laughable.
Chosen answer: It's the house number of Dom's old house in Los Angeles, from the first film. Hobbs says "name your price", so I guess Dom was asking him to buy his old house back (the gang are having a BBQ there in the next scene).
