The prices for insurance coverage available next year from the federal Obamacare exchange will be posted online starting Sunday, federal officials said, as they unveiled consumer-friendly upgrades to the digital marketplace for its third open-enrollment season.

An Obamacare enrollment informational pamphlet sits on display at a Community Clinic Inc. health center in Silver Spring, Maryland.

The announced improvements include simplifying re-enrollment in current Obamacare plans, encouraging enrollment in plans that are best financially suited to a given person, and reducing the number of cases of people failing to provide information about their Social Security numbers or other data required to prove eligibility.
