I've checked some translations in the office from Chinese to English. My job is just to correct some of the grammar. We are all confused in the use of 2 or more Id[identification card]. It is actually used as plural possessive form. The original translator wrote it as " id's photocopy". So I've been thinking that it's only a singular possessive form of noun, so I corrected it because there are 2 or more IDs to photocopy, instead I've wrote "IDs' photocopy", to make it plural possessive form. Can I use IDs'? is it acceptable?, or how to write ID in plural possessive form? I would greatly appreciate your advice on this... thank you...

You are making it more difficult and awkward than it need be. Inanimate objects seldom use the '-s' possessive. Use the noun as an adjective, which works for one or more IDs:

'ID photocopy' / 'ID photocopies'.

Or, you should use 'Photocopies / A photocopy of the IDs'.

hi
I´m confused about the spelling of the word dialled, Is that the correct spelling or is it dialed?

[Mister Micawber]

British spelling uses 2 'L's.
