Could an mobile App access hardware information like IMEI or serial number without my acknowledgement?

In addition to IMEI and serial number what is the information that could be used to distinguish one device from the other assuming that they are of the same models)

Not anymore due to increased sensitivity for privacy

See here http://nshipster.com/uuid-udid-unique-identifier/
And original document for UIDevice class

You can also look into the samples for notification where a unique ID is provided; might be useful too.

Whatever you do: respect the privacy of users and watch what Apple gives as rules to avoid rejection.
