Your CHESS holding statements will have your HIN/SRN on them, as long as you can find one for any of the holdings you have/had, it should work, as long as 'postcode' verification matches Link-DB...
I am sure I've seen them start with an 'S' also, but not according to the info below...
"A HIN or SRN can have up to 12 characters, usually starting with an 'X', 'I' or 'C' followed by up to 11 digit number, for example 'X00012345678' or 'X12345678'.
The HIN or SRN can be found on the top right hand corner of your holding statement and other shareholder communications.
A HIN, being Broker sponsored, commences with an 'X'. If you have an account number from a CHESS statement you will need to add an 'X' to the front of the account number before logging in.
A SRN, being Issuer sponsored, commences with an 'I' or 'C'. You will need to enter the 'I' or 'C' followed by the 11 digit number before logging in.
Important note - your HIN/SRN identifies you as the owner of your securities and should be stored securely..."
