Is there a specific symbol for $\mathbb{N}\cup\lbrace 0\rbrace$?

Question

It is well known that natural numbers start in 1.

However, sometimes people work with a "widened set" of natural numeres plus zero, $\mathbb{N}\cup\lbrace 0\rbrace$. That is, all non-negative integers.

Is there a specific symbol for this set? such as $\mathbb{N}^{*}$, $\mathbb{Z}^+$ or anything similar? Thank you

Answer 1

$\mathbb{N}_0$ is the most common choice.

Answer 2

I've seen $\mathbb{N}_0$. But saying $n\ge 0$ is not heavy lifting.
