KUT Radio (Ashley Lopez, https://www.kut.org/politics/2022-01-13/texas-senate-bill-1-election-officials-vote-by-mail-identification) is reporting:
“Travis County Clerk's office says that as of today, their office 'has rejected about fifty percent of applications for ballot by mail that have been received for the March 1, 2022 primary election,' due to changes to ID requirements made by Texas' new voting law.
"The new law, SB 1, requires that voters provide the same ID number -- driver's license, social, etc. -- on their VBM app that they provided on their voter registration. Many folks who registered a long time ago, don't remember what ID they used.
"For those asking, according to the @TXsecofstate's office, you can correct the ID information using the state's new ballot tracker website: teamrv-mvp.sos.texas.gov/MVP/mvp.do”

====
• If you are applying for ballot by mail be sure to include both driver’s license and social security numbers.
• If you have already applied, check the status of your application on the SoS site mentioned above or with the County.
NOTE: At the time of this writing, the vote by mail part of Travis County’s https://votetravis.com is off line.
Follow up: I looked up my BBM status on the SoS website. They showed no status for 2022. I just voted by mail in the local special election.
