Your data and security : How we will contact you

At the Office for National Statistics, we made sure every household and managed accommodation in England and Wales had a Census 2021 questionnaire. We did this by creating an address register from Royal Mail and local authority address lists.

We sent you census information by post, including details about how to fill in your census questionnaire. You can contact us to request a paper census questionnaire, which will be sent to you by post.

We will not:

  • visit you
  • call you for information about your census, unless you’ve made a query or complaint
  • email you, unless you’ve contacted us
  • ask you for your national insurance number, passwords, bank account details, or your credit or debit card numbers

If you have received a text message, phone call or email about the census, this could be a scam. We will not contact you via a text message, email or phone call asking for your details or regarding a fine. We're working very hard to get these websites taken down.

Please don't engage or respond to these messages and don't click on any links provided. If you've completed your census, you will not be fined. If you wish to report the scam to us, you can contact us. Please provide as much detail as you can, for example, a telephone number or a link to the website.

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