There’s no way to tell how many people who think they enrolled for health insurance through the U.S. Obamacare exchange actually have, after about 1 in 4 files sent to insurers had garbled and incomplete information.

The data transmission errors have been reduced to 1 in 10 since Nov. 30, the government said on Dec. 6. Still, the acknowledgment suggests consumers need to be vigilant about their health plan purchases. Letters from insurers confirming coverage can take a week or more, and the Obama administration now says people should call their companies if they aren’t contacted within that time.
