The old portal for checking PF balance is down because a new portal has been introduced by the government. The New Portal (EPFO) is a revamped version of the old one but does not come with extra options/facility as compared to old one.EPFO has put up a new portal for ECR 2.0 and is experiencing huge traffic. The maintenance/integration of other portal is also in full swing on account of centralization of data.
But, still it is more user friendly and have a fresh UI.
EPFO is moving to new website and all data is synchronizing to new UAN Link. hence the websites were down since December 2016.
New UAN link is Member Home, where you can activate UAN, Know your UAN, Change Mobile number through option “change Password” & upload your KYC (Aadhaar is mandatory, PAN & Bank details)
