What are the weird number boxes on peoples bebo pages?

[Scadoosh-x]

Recently Ive noticed little squares on most my friends bebo pages. They have two lines, each line with two numbers on them. I thought they might be symbols that I need to install onto my computer? If so how do I get them and what are they likely to be of? thanks in advance
