What happens if you use one of the NPC’s uniform numbers in Sword/Shield?

Question

Pretty clear question, what happens if you choose one of the other NPC’s trainer uniform numbers as your own? Marnie is 960, Bea is 193, Hop is 189 etc on and on. Does it change anything in-game if you choose the same number as one of them?

Comments

Likely nothing, but I can't find anything that directly proves this.
