March 8 (UPI) -- An error caused thousands of residents in Colorado to appear much taller on their driver's licenses and state IDs.

More than 12,000 people renewed their identification online between Feb. 20 and March 6 had their height misprinted due to an error by Marquis ID Systems, which produces the documents for the state.

"They had asked us to file height in inches, and that was what was done, but they failed to do the conversion," Colorado Department of Revenue spokeswoman Lynn Granger said.

Granger explained the error resulted in people who would measure 71 inches tall being listed much taller.

"Instead of converting to be [5-foot-11], it's [7-foot-1], so there was just that minor error with the listed height on our driver's," she told CBS Denver.

The state said it was aware of the issue and Marquis will send replacement IDs to affected customers free of charge no later than March 10.

The misprinted licenses will remain valid while replacements are being mailed to residents.

Granger added that the state will continue its partnership with Marquis to produce the IDs despite the mistake.

"I don't think we will be switching anytime soon," she said. "They have apologized for the error, and we're happy with that, and that there will be no cost to either the customer or the state."
