How to pay for missing National Insurance Years

Hello, Please can you tell me if it is still possible to pay for gaps in my National Insurance by cheque ? I am not yet of pensionable age and the pension website shows the increase that I will get in my state pension if I pay for my missing years of National Insurance. I can see quite clearly on the pension website which years I need to pay for and how much this will cost so can see no reason to contact the Future Pension Centre. Many thanks Sarah
