Obtaining a NHS Test and Trace Account ID NHS Test and Trace uses a web-based tool called the Contact Tracing and Advice Service (CTAS) to record information about people who have tested positive for COVID-19 and their contacts.

How applicants obtain an NHS Test and Trace Account ID Most people who test positive for COVID-19 or are a contact of someone who has had a positive test will receive a digital invitation from the CTAS web tool to undertake the contact tracing journey. The invitation message (sent via a text message or email) contains the 8-character Account ID. Everyone who has completed the contact tracing journey (including those who were ineligible for the digital invitation, such as children or individuals with a landline number only) will receive a message upon completion of the NHS Test and Trace questionnaire. The message (sent either via a text message/email or postal service for people with no access to mobile phone or email) contains the 8-character Account ID.
