Excuse me to ask you this.
The following is the sentence on the famous dictionary.
"Some software can be configured to prevent children from giving out their phone numbers on the internet."
I searched the meanings for give out on the same web dictionary, and I found the meanings of 'give out'. It says:
phrasal verb
(NOT CONTINUE)
to last no longer, or to work no longer:
Food supplies will give out by the end of the week.
I think the upper one means the other meanings such as 'pass on', 'release' or so.
Is it right or not?
Yes, you're right. "Giving out" here means: to provide, pass on.

Yes, you're right.
"Giving out" here means: to provide, pass on.
In your sentence, as you thought, 'pass on their phone numbers' means give/reveal their phone numbers to somebody.
The dictionary does not list this meaning because in this context. 'pass on' is not a phrasal verb: it's just a verb with a preposition.
