US mailbags containing personal information are no longer required to have a signature seal on them, a U.S. Postal Service official said.
Under new rules announced on Monday, all envelopes must now have a self-sealing envelope label, with the seal indicating the sender’s identity.
The change comes as postal workers are under pressure from lawmakers to crack down on identity theft and other crimes.
A few weeks ago, the Postal Service announced it would be reducing the amount of time it takes to receive letters.
In October, the USPS said it would begin requiring envelopes to have self-service labels that will help employees better identify each envelope.
The Postal Service, which serves about 75 million U.N. recipients, has been under pressure to improve security since the November election, where it lost its first three presidential elections in a row.
