In line with future expansion, technical issues and international standardization All our alphanumeric codes now consist of seven characters.
All postcodes within the zones NW1 to EC5 will be increased from six to seven characters.
If you presently have a six character code, simply add a G to the end of the code. For example, if your present postcode code is NW1 186 simply add a G to the end. Thus your new postcode is NW1 186G. Here’s another example, EC5 837 changes to EC5 837G. It’s that simple.
If your address is within the SE6 Galway postal district zone – these changes do not apply to you.
