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

How we will contact you

We sent you census information by post, including details about how to fill in your census questionnaire. You can still complete your form by requesting a paper census questionnaire, which will be sent to you by post.

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
  • email you unless you’ve contacted us using our web form – our responses will come from
  • text you unless you’ve texted us – our responses will come from 86677
  • 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 send us a message using our web form. Please provide as much detail as you can, for example, a telephone number or a link to the website.

If you manage accommodation where people live or stay, visit our guidance for managers page to find out how we may contact you.

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

I’ve received more than one letter

We’re sending letters to everyone who has not submitted their census form. Visit our why have I received a warning letter page to find out more.

Why we may still need to visit you

If you do not fill in the census after you've received a warning letter, you may be visited by officers from our Non-Compliance team. They will encourage you to fill in your form and will help you access any support you need to complete your census.

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

If you suspect that a person at your door is not a genuine census officer, close the door. If you feel unsafe, call the police.

Our Non-Compliance officers may visit when you've already submitted your census

Follow the guidance on our why have I received a warning letter page, as you may have had a visit for reasons described there.

Visits from the Census Coverage Survey team

The other reason we may visit you is if we need you to complete the Census Coverage Survey.
