Your data and security : How we will contact or visit you

At the Office for National Statistics (ONS), we will be carrying out the census for England and Wales in March 2021.

We’ve created an address register to make sure that every household and managed accommodation in England and Wales gets a census questionnaire.

To do this, we combined a list of addresses from Royal Mail and another list from local authorities. We also carried out address checks in some areas to improve the accuracy of our register.

We will send you census information by post including a letter containing the access code needed to fill in your census online questionnaire.

We will not call you for information about your census, unless you’ve made an appointment with our Contact Centre or made a query or complaint.

We will never ask you for your national insurance number, passwords, bank account details, or your credit or debit card numbers.

Any emails from us will be sent from: noreply@help.census.gov.uk

Any texts you receive from us will be sent from Census2021. If you text us, our responses will come from 86677.

Our data processing and contact centres are in the UK and subject to UK data protection legislation.

Our census officers may visit you

Census officers may visit to offer help if you’re yet to complete the questionnaire. They may also visit to make sure that everyone has been counted. They will identify themselves as being from the ONS and carry an official ID badge. Census staff will never ask to enter the property.

Census officers visit during the following times:

  • Monday to Saturday: 9am to 8pm
  • Sundays and bank holidays: 10am to 4pm

We don’t wish to disturb your evenings or weekends, but we might visit at these times because this is when most people are at home.

We carry out employment checks to make sure that everyone working on the census is qualified to work with the public.
