call (at) 12345678

[GeogeHalin]

Hello members!

There's a number a person can call if he needs help. So I say to him:
1. You can call 12345678 if you need any help.

I think we don't add 'at' before the number.
Unless it's "You can call me at 12345678 if you need help."

Is that correct?
Thank you!

Or should it be 'on' instead of 'at' in sentence 2??

Absolutely.

I think both "on" and "at" can be used. May be a BrE/AmE difference or a personal preference. I'm not a native though.

"On" would be wrong. "At" is correct.

Thanks!
And sentence 1 is correct right? We don't use the preposition there?

"On" would be wrong. "At" is correct.

It is a BrE/AmE thing. "On" is just fine in BrE.
You don't need a preposition if the object of call is simply the number, so your first sentence was fine. You do need one if it is "call me at/on 12345678".

Yes, have a look at:

call at your home phone
contact me on/at this telephone number


The verb can be call, phone, ring or contact. The preposition is either at or on​.
