Incorrect regex for numbers

I need a regex that matches only 10, 11 and 12 numbers. I tried this:

\b[10|11|12]{1}\b

But no matches found here. Could you help me out?

You should use

\b(10|11|12)\b

Check it at work here

Also, no need to specify {1}, it is implicit.

Square brackets are used to match a character from a set

Match anything inside the square brackets for ONE character position once and only once, for example, [12] means match the target to 1 and if that does not match then match the target to 2 while [0123456789] means match to any character in the range 0 to 9.
