NIC and maximum state pension

Hi, One question, my National Insurance record online shows 41 years of full contributions, but also says that I need three more years to be entitled to the maximum will get. I had understood that I need 35 years full contributions for my  maximum state pension. Do you understand this, and do I need to make more contributions?

Hi Jack Xu,
If you contact the DWP Future Pension Centre, they will be able to check your National Insurance account and let you know the number of tax years
that you need to get a full State Pension. You may wish to obtain a State Pension Forecast or giving them a call.  
The following weblink will give you further information:  Check your State Pension forecast
Thank you.
