What is a CRSid?

Your Cambridge CRSid (Common Registration Scheme identifier) is a unique username issued by University Information Services (UIS). It is used to identify an individual on any online system managed by UIS, including Raven, Hermes and Desktop Services.

It is also used as a username on many computing systems managed by other University Institutions. In particular, the CRSid forms part of your standard Cambridge @cam email address.

You can find out what your CRSid (and therefore your @cam address) will be before you arrive in Cambridge, but you will not be able to read your @cam email until you have collected your initial UIS Password.

  • Postgraduates
    If you are a new (to Cambridge) postgraduate student you can find out what your CRSid and email address will be, usually within a couple of weeks of receiving an offer. You will be asked for your Board of Graduate Studies admissions number which is quoted on all correspondence from the Board, and your surname. 

    If your application was not processed through the Board of Graduate Studies, or is still in the process of being approved, or your College has not yet been finalised, you will not (yet) be able to use this mechanism.

    Postgraduate students who were previously undergraduates at Cambridge will retain their CRSids and email addresses.

  • Undergraduates
    In late August before the start of your first year, you will be sent an email from the Student Registry () containing instructions about completing student registration prior to collecting your CRSid and email address.

  • Staff
    If your College or Department has arranged for your UIS accounts to be created before your arrival, you can find out your CRSid and address and collect the passwords for your accounts. You will need a registration code from your Institution.

What will my CRSid be?

Your CRSid is generated from your initials followed by some digits. For example, a Cambridge user called 'Alison Beth Cooper' might be assigned the CRSid abc123, and so her @cam email address would be

Note: It is not possible for you to request a specific CRSid because they are randomly generated by our user administration system. CRSids are unique to an individual person, and will never be reissued – your CRSid lives on in perpetuity, whether or not it is currently active.
