Plans for a new parliamentary constituency called Antrim Coast and Glens have been dropped.
Northern Ireland currently has 18 seats at Westminster
The Boundary Commission said there was no support for the idea.
This is the major change in revised recommendations which have been published following public inquiries in Belfast, Newcastle and Ballymena.
New boundaries are being proposed in 12 of Northern Ireland's 18 Westminster constituencies, but the changes are not as sweeping as earlier proposals.
Belfast's four constituencies are being extended outwards to incorporate Carryduff, Dundonald, Dunmurry, Lagmore and Glengormley
With the Antrim Coast and Glens plans dropped, East Antrim survives and is being given three wards from the massive North Antrim constituency.
Some changes will also be made to Strangford, South Down, Lagan Valley, Foyle and East Londonderry.
Despite earlier proposals to the contrary, the constituencies of Newry and Armagh and Upper Bann are both unchanged.
