As the first 2 letters indicate the area of registration - it is more likely to be seen in the same area. There are lots of instances of cars with similar reg numbers - theirs is just 6 months newer than yours - a coincidence but not unlikely - a fairly common car in a common colour - registered in the same area.
Hi, the only advise I can offer on your question, start making notes of where you where if possible you never know you may have been camerad, parking bad driving or anything to that effect.
