Its company number 04054040 shows it was registered in England and Wales, so its records are kept by Companies House in Cardiff. It has been on the register for 26 years and 2 months.

Where COMMSONIC LTD. is registered

Its registered office is in Cambridge (postcode district CB4). The registered office is the official address for letters from Companies House, HMRC and the courts.
