IELTS Award Refernce Number

[imran99132]

Hi,

I was filling the TIER 1 application form and I came across this question in the English proficiency requirement section.
For an IELTS certificate as evidence what would be the "Award Reference Number".
I've checked the IELTS certificate and there is no refernce number, but there is a "Test Report form number" which is 18 digits long while there are only 14 boxes in the application form.
Could somebody please advise.

Thanks
