Individual Electoral Registration

The process for registering electors has changed.

The registration system changed in June 2014. The new system is called ‘Individual Electoral Registration’ (IER) and is the biggest change to the voter registration system in 100 years.

Most people who were already registered will have been transferred automatically to the new register. However some people will have had to re-register in Isle of Anglesey County Council. There are also people in the area who have not registered to vote at all and so need to register to have their say in elections.

Previously, one person was responsible for registering all electors in their household. Now each individual is responsible for making sure they are on the Electoral Register.

If you weren’t registered previously, you can register under the new system at or by telephoning the Elections Offices on 01248 752548.

You need to provide a few more details to register – including your national insurance number and date of birth. This makes the electoral register more secure. Please ensure you have these to hand if you are using the online system or if telephoning the Office.

If you cannot find your national insurance number you can use the HMRC enquiry service at, or ring 0300 200 3502.

If your name, date of birth or national insurance number are not verified (matched) after you have applied to register, we will contact you asking for further documentary evidence, such as a copy of your passport or photo drivers licence.
