My guess would be that the number is the "service number " of the individual that the badge was given to. The company name may be either the firm that made the bagde, or an employer of the man who it was issued to, post war.

My Dad was a First World War veteran of the Canadian Army, and during WW2, he wore a "Veterans' Service " lapel badge on his civillian clothes, to show that he had all ready "done his bit " 20 years before hand.

At the end of WW2 Canada issued a similar "overseas service " badge to returning servicemen and women, so show they had been "serving Canada ". They also got a wall hanger "certificate of service " signed by the Prime Minister, and the King.
